| Abstract | Poly[(benzo[1,2-d:5,4-d']bissthiazole-2,6-diyl)-1,4-phenylene](cis-PBZT)with a relatively high molecular weight was prepared by a new synthesis route. Properties of the synthesized polymer, such as thermostability, liquid crystallinity etc. were investigated and compared with those of trans-PBZT. cis-PBZT was crystallized from dilute solution and the electron microscopy showed that the precipitate was a rod-like crystal similar to that of trans form. In spite of rigid nature of the back bone, cis-PBZT showed poor crystallinity. |

| Abstract | The author investigated the effect of the radioactive thermal bath upon the carbohydrate metabolism and the leucocyte picture in alloxan-diabetic rabbits. 1. The author injected 100-200 mg. of alloxan per kg. of body weight intravenously into normal rabbits and produced alloxan diabetes. The triphasic blood sugar response to the injection of alloxan is illustrated in Table 1. and Fig. 1. About a week after the injection of alloxan, the fasting blood sugar values ranged 127 to 331 mg./dl. (Table 3.). 2. In this experiment the alloxan-diabetic rabbits were put in radioactive hot spring and plain water bath, 42-44℃. in temperature. The radioactive hot springs put in use are "Hisui-no-Yu" and "Kenkyusho-sen" (the Loboratory-Spring), both in Misasa Spa, the chemical compositions of which are given in Table 2. 3. In any case, the blood sugar level rose temporarily after the thermal baths for 5 minutes, but the 24-hour blood sugar value after taking a bath was lower in "Hisui-no-Yu" (Rn: 300-400 Mache units) than in "Kenkyusho-sen" (Rn: 10-30 Mache units) (Table 3 and Fig. 2). 4. The glucose tolerance was found to be abnormal in alloxan-diabetic rabbits even 3 months after the injection of alloxan, but this abnormal carbohydrate metabolism tended to become normal by the radioactive thermal bath (Table 5, 6 and Fig. 3, 5.). 5. The radioactive thermal bath in "Hisui-no-Yu" caused increase of leucocyte counts of alloxan-diabetic rabbits more remarkably than the bath in "Kenkyusho-sen" (Table 8. and Fig. 6). |

| Title Alternative | RHEUMATOID ARTHRITIS AND THORN'S TEST |
| FullText URL | 015_029_033.pdf |
| Author | Izumi, Tomokuni| |
| Abstract | In a course of balneotherapy of rheumatoid arthritis, there was no proper standard to judge the therapeutic effect. In this circumstance, Thorn's test and a measurement of red cell sedimentation rate were applied to ten patients with rheumatoid arthritis before and after balneotherpy, and it was found that, although patients before therapy showed a low value of Thorn's test and a faster rate of red cell sedimentation, after released from various symptoms by balneotherapy they had a higher value of Thorn's test and a slower rate of red cell sedimentation. Therefore, these two tests above described may be used as a standard for a judgement of the effect of balneotherapy to patients with rheumatoid arthritis. |

| Abstract | Dependence of precipitation hardening on the distance from specimen surface and effect of the surface layer on the fatigue strength of an Al-1.2mass% Si alloy were studied by microhardness test, transmission electron microscopy and repeated tension fatigue test. Rate of age-hardening was slower in the vicinity of surface than in the interior of the specimen aged at 423K after quenching from 853K. The result of the electron microscopy was that the size ot Si precipitates formed in the vicinity of surface was smaller than in the interior of specimen aged for 6ks at 423K. This difference was considered to be caused by the effect of the surface as vacancy sinks which slowed down the growh of Si precipitates in the vicinity of the specimen surface. A specimen surface layer whose hardness was different from that of the specimen interior was formed at the vicinity of the surface when the specimen was aged at relatively low temperature such as 423K. The fatigue strength in repeated tensile test ot the specimen did not depend on whether the specimen surface layer was present or not. |

| Abstract | In this paper, we propose a method to solve simultaneously facility layout problem and scheduling problem. About a initial random layout planning, the production scheduling and the transportation scheduling of AGV are obtained by using priority rules. From the obtained transportation scheduling, the critical transportation and the closeness rating are obtained. Facility layout is renewed by the combined procedure of genetic algorithm and tabu search in order to reduce the material handling cost. By using this renewed facility layout, the production scheduling and the transportation scheduling of AGV are also revised until no further improvement is possible. |

| Abstract | A method for designing a monitoring system with multiple cameras is proposed in order to supervise and recognize the progress of wide work area. First, a wide view camera is deveeloped by combining several usual cameras so that its visual angle could cover more than π/2. Secondly, A method for determining the number and location points of cameras is proposed by considering the shape of monitored area and the installation cost of cameras. The monitored area is divided into three kinds of basic shape (rectangular form, L form and convex form). For every basic shape area, the camera is located at the vertex pasition, so that the whole area can be monitored by the camera. |

| Abstract | In this paper, we propose a recognition index to evaluate the complexity of discrimination among parts and units. The parts and units are classified into some groups (the number of groups is shown as n) by one characteristic, such as color, shape, size and so on. The recognition index of each is denoted as log(2) (n+1) by the information quantity formula. The recognition diagram shows the classfication of parts and units into only one part and unit by the structure of a characteristic. Further we propose the line balancing method for assembly line based on the working time and recognition index. |

| Abstract | The present paper deals with measurements of the diffusion coefficients as well as the saturated solubilities of single component gases such as N(2), O(2) and CO(2) to a mineral oil. The method to determine the diffusivity is based upon measuring the pressure changes caused by the one-dimensional diffusion between the gas and the oil enclosed in an airtight container. For N(2) and O(2) the profiles of the measured pressure changes agree well with those predicted by diffusion theory, whereas that is not the case with CO(2). Although the reason why CO(2) does not seem to obey diffusion theory has yet to be studied, it may suggest the possibility that the diffusion coefficient varies with the pressure, considering that the range of pressure change in the diffusivity measurement was much obtained by this method fell within ±30% around the average. Moreover the solubility measurements have made clear that Henry's law holds true between the three pure gases and the oils tested, and that O(2) and CO(2) dissolve into the oil approximately two and ten times more, respectively, than N(2). |

| Title Alternative | EFFECT OF WATER LEVEL OF RIVER ON MINERAL SPRING (Continued) |
| FullText URL | 015_011_015.pdf |
| Author | Umemoto, Shunji| |
| Abstract | From February to September 1954, observations were made of the rates of flow and the water temperatures at a spring called "Tanaka-no-Yu", Misasa Hot Springs, Tottori Prefecture. Simultaneously with these observations, the water level of the River Misasa and that of an irrigation stream nearby were also determined. The procedures for the observations were the same as in the previous report. Comparing the results here obtaind wite those previously obtaind, and referring to the conclusions in the previous report, the author has been led to the following conclusions. From the observations in the period from February to September, 1954, as from those in the period from June, 1953 to January, 1954, a positive correlation was found between the rate of flow and the water teperature, the correlarion coefficient being 0.828 (highly significant). The analsis of variance of the obseryed results showed that the rate of flow and the water temperature appear to be affected by the water levels of the River and of the irrigation stream, and also by their interaction. This conclusion supports what was deduced in the previous report. The average water levels of the River and of the irrigation stream, the average rates of flow and the average water temperatures, for the period from June to September in 1953, were compared with those for the period from June to September in 1954. The differences in the average water levels of the River, the average rates of flow and the average water temperatures are significant; while that in average water levels of the stream is not significant. From this it may be concluded that the increase in the rate of flow and the rise of the water temperature were resulted from the upheaval of the water level of the River, which followed the construction of a dam there. |

| Title Alternative | STUDIES ON THE CHLORIDE AND SULFATE CONTENT OF WELL WATERS AND THE AMOUNTS OF CHLORIDE AND SULFATE FIXED TO SOIL IN THE MINERAL SPRING DISTRICTS (IX) SAGINOYU HOT SPRINGS, SHIMANE PREFECTURE, JAPAN. |
| FullText URL | 015_001_005.pdf |
| Author | Umemoto, Shunji| Tanaka, Shigeo| |
| Abstract | At Saginoyu Hot Springs same experiments as those described in previous reports were carried out. Water temperature of Springs is about 50℃. and main constituents dissolved in spring water are calcium sulfate and sodium chloride, its total salt content being 1.5g./ℓ.. Experimental results obtained are shown in the annexed table and map. The results obtained may be discussed in two ways: First, the area marked with ※ is regarded as the spring zone, and a comparison is made by Cochran and Cox's method between this zone and the outside area as to the average contents of chloride and sulfate in well Water, the average water temperatures of well water and the average amounts of chloride and sulfate fixed to soil. The differences in averages of the chloride and sulfate content of well water are significant, while that in average water temperatures is not significant. The differences in the average amounts of chloride and sulfate fixed to soil are not significant. However, the difference in the average amounts of chloride fixed to soi1 is nearly same as that for the 5 % level, and it is seen that the average amount of chloride fixed to soil tends to be higher in the spring zone than in the outside area. Second, the area marked with t is regarded as the spring zone, and a comparison is made in the same way as the above. The differences in the averages of the chloride and sulfate contents and water temperatures of well waters, all being higher in the spring zone, are significant. The differences in average amounts of chloride and Sdlfate fixed to soil are not significant. However, since these differences are nearly same as that for the 5 % level, the average amounts of chloride and sulfate fixed to soil tend to be higher in the spring zone than in the outside area. As the existence of sources which would supply the chloride, sulfate and heat to the water and soil is impossible, the above differences may be due to effects of thermal springs. Since the spring zone may be defined as the zone effected by mineral springs, it is more appropriate to follow the second of the above two ways than to follow the first, and to regard the area marked with t as the spring zone. Then, the differences between the spring zone and the outside area are revealed more remarkably than otherwise. It is an interesing fact that the samples Nos. 3-6, though collected from the spots very near to the springs, do not belong to the spring zone. |

| Abstract | At present, the two dimensional CAD systems which are used to make drawings go around widely. But in order to use design data at the lower stream of production process, the replacement from the two dimensional CAD systems to the three dimensional CAD systems have started. Accordingly it is dimensional drawings for the three dimensional shapes. And it is also necessary to store them in the three dimensional CAD systems. And in the studying of the machine vision which is often used as "Eyes of robot" , it is being studied the method to recognize the three dimensional objects from the two dimensional image. This is the problem about data exchange, too. Therefore in this report, we propose the method to exchange the plural two dimensional elements of figure from image relations between elements were found from reference of the element coordinates. Next, the three dimensional shapes were reasoned from reference of the knowledge (for corner, etc) prepared beforehand. Then that data were exchanged to the three dimensional CAD data. We report one example about this method. |

| Abstract | This paper presents a method using simulated annealing(SA) and genetic algorithm(GA) to solve the plant layout problem in which the layout is evaluated by material handling cost and maintainability. In the former study about facility layout problem, it was either the minimization of the objeective function consisting of transport cost or the maximization of the objective function consisting of closeness rating. In this paper, both transport cost and maintainability were included in the objective function to be minimized. The plant layout problem, this paper proposes the heuristic procedures to obtain a suboptimal layout solution by combining SA with GA. From the simulation by computer, it concluded that the method which SA is combined with GA is more efficient than the method which utilizes SA and GA independently. |

| Title Alternative | EFFECTS OF RADIO-ACTIVE THERMAL BATH ON OXIDATION- REDUCTION SYSTEM |
| FullText URL | 007_035_081.pdf |
| Author | Sotozono, Masazumi| |
| Abstract | The author proved that consumption of iodate by proteinfree serum filtrate, an index of total reductive substance in serum filtrate, was increased after a radioactive thermal bath of Misasa (400-700×10(-10) Curie units Rn per liter), at a temperature of 40°～45℃ for five minutes. Reduced glutathion in blood showed little change, but oxidized and total glutathion tend to rise and decreased only temporarily. Reduced ascorbic acid in blood and urine increased after the radioactive thermal bath, but the oxidized and total ascorbic acid decreased after a temporal increase. After the thermal. bath a tendency of fall in reduced and oxidized ascorbic acid content was observed in liver, lung, and adrenal glands, and a tendency of rise was shown in kidney, spleen, skin and musclein albino rats. By a series of daily successive thermal baths a fall in ascorbic acid content was observed in most of the organs examined in the first week (on the fourth day) and then a reactive increase was shown during the second week. |

| Abstract | The thermal expansion coefficient of some bioactive glasses in the system CaO-SiO(2)-B(2)O(3) were adjusted to be similar to that of titanium by controlling the composition. A glass of composition 45CaO･30SiO(2)･25B(2)O(3) was selected among those as the enameling glass. A slurry was prepared by mixing the glass powder and ethanal to be developed on titanium and heated at 740℃ for 30 min. Thus treated specimen was soaked in a simulated body fluid (Kokubo solutiion). FT-IR reflection and thin film X-ray diffraction analyses indicated apatite formation on the glass coating layer within 12 h of soaking in the fluid. Thus titanium could be provided with bioactivity due to the enameling. |
