| 抄録 | The Reformatsky reaction with t-butyl haloacetate could be effected in the presence of lithium or aluminum, but the latter metal proved to be disappointing as a condensing agent. Condensation of benzophenone with t-butyl chloroacetate and bromoacetate in the presence of lithium gave corresponding β-hydroxy esters in yields of 43 and 58%, respectively, and comparable with those of other condensing methods. |

| 抄録 | The preparative method of giant single crystals of PEO and the experimental results of them by x-ray diffraction and electron microscopy are described. The crystallization of PEO was carried out in a two dimensional crystallization apparatus. From the tridirectional x-ray diffraction patterns on the resulting platelike crystals, it was confirmed that these crystals have a single crystal-like orientation at high supercoolings, the [401] axis is parallel to a growing direction and the [001] axis is perpendicular to the wide surface, and a double orientation at low supercoolings, two axes of [421] and [421] are parallel to a growing direction and the [001] axis is perpendicular to the wide surface. |

| 抄録 | Sensitivity of mice to histamine was estimated with the death-rate by its subcutaneous injection. In control group without bath ten mg. of histamine per ten g. of body weight proved to be tolerable, but twenty mg. of histamine per ten g. of body weight was lethal in August. To 24 mice were given everyday a plain water bath at 37℃ for ten minutes. To another 24 mice were given everyday a thermal bath of Misasa at 37℃for ten minutes. On the 4th, 7th, 14th and 21st day to each six mice of both groups was given a subcutaneous injection of histamine, namely to three mice was given ten mg. of histamine per ten g. of bodyweight and to another three mice was given twenty mg. of histamine per ten g. of body weight. In plain water bath group no change in death rate was shown during the series of bath days. But in the thermal bath group a 100% 1ethality was recognized on the 4th day, 67% lethality was proved on the 7th day and only 17% lethality was shown on the 14th day. Histamine or histaminelike substance is known to be a chemical agent liberated in the skin by any skin irritants. And the above-mentioned change in the sensitivity to histamine during a series of thermal baths suggests an explanation to the mechanism of thermal crisis that has a tendency to occur in the first week of thermal bath cure. |

| 抄録 | Decomposition voltages of Na(2)O (30-50 mole % )-SiO(2) binary system were estimated at the temperature range of 700~1200℃ by commutator technique. As the experimental procedure, relations between electrolytic current and resulting polarization potential without ohmic loss were observed by 20 cps mechanical commutator, using Pt|Na(2)O-SiO(2)|Pt electrochemical system. Experimental decomposition voltages determined from above relationship were the value of 1.5~2.0 V at the temperature beyond about 800℃ with comparatively less reproducibility. Further investigations on the decomposition reaction mechanisms were made in reference to both a series of reversible decomposition voltages derived from thermodynamic calculations on the several proposed decomposition reactions and chemical equilibrium in vitreous silicates. |

| 抄録 | Tottori Hot Spring belongs to a muriated sulfated spring with twenty seven spring sources in 1949. But since 1949 about ten new springs are permitted to bore by the Prefectural Council on Hot Springs. And so the total amount of flow or the capacity of Tottori Hot Spring became a matter of concern among the citizens of Tottori. By the relationship between the chloride and sulfate or chloride and bicarbonate content of spring waters, it was concluded that all thermal springs of Tottori City derive from a same thermal source. As Tottori Hot Spring did issue out without aid of a pump in former days and nowadays does not, it seemed possible that a gradual fall of thermal water level took place and was golng On. ln most of Tottori Hot Springs a moter of one horse power was enough to pump up the thermal waters. But it occured that in one of the newly bored spring a pump With a three horse power motor was found being in use without permission of the Council. So the author took the chance of investigating the influence of the pumping of the new spring on the temperature, amount of flow, and chemical composition of waters of the surrounding springs. And he found that pumping up with three horse power motor could lower the water level and change the Chemical composition of some of the sorrounding springs and warned the Council of the danger of an abuse of permission to bore springs. |

| 抄録 | In this report, the analogies of the maximum allowable liquid and gas velocities in various countercurrent gas-liquid contactors of column type are considered analytically. That is, by plotting the flooding points of various columns in a gas-liquid separated coordinates, the similar curves have been obtained in each column. Because the difference of these curves is due to the shape of each column, the difference of each shape must be corrected and evaluated as a ahape factor. Then, by containing this factor in coordinate variables, various flooding points in each column may be correlated by a single curve. If this correlation curve is used, the flooding velocity can be estimated easily, and the maximum allowable liquid and gas velocities in these countercurrent contactors of column type can be compared. |

| 抄録 | Binding energies between a vacancy and an atom of lead or gold were measured with the same method as those previously reported. The solid solubility of lead or gold in aluminium is very small, and the small quantity of precipitates are found along grain boundaries in this experiment. Therefore, it was not possible to determine the value of binding energy, but the lower limit of binding energy was estimated. The values of lower limit for Pb-Vacancy and Au-Vacancy binding energy were 0.38 eV and 0.35 eV, respectively. |

| 抄録 | An analysis is attempted of the human operator's responses to the sinusoidal input and the random input. The human operator's characteristics in the closed loop system are represented by the Bode diagram. This diagram shows that the human operator's response to the random input containing only those frequency components lower than 4 rad/s is almost in accordance with his response to the siunsoidal input of the same frequency range. |

| 抄録 | There are a number of methods for measuring the fatigue because the measurement of this in the working hours is useful for analyzing the factors of fatigue and for the utilization of the labor management. In this paper, the fatigue of bus drivers who have experience of various number of years in some bus company is measured by the flicker and these values are analyzed by X(2) test or sign test and its control limit is determined. These are contributed to find a daily variation and to estimate the fatigue capacity, the degree of skill and what factors have influence on points which oversteps the limit line. It was found in this study that the limit line gets lower as the year of experience increases and the flicker values decrease in the forenoon. |

| 抄録 | In order to clarify the sealing mechanism of an oil seal, it is necessary to know its fundamental properties and movement now in action. There are two subjects in this study. One is to reveal the temperature dependence of fundamental properties, mainly wringing force, average wringing pressure and lip contact width, and the other is to know the lip temperature now in action and to know how the lubrication is carried out at the lip portion. The measurements were carried out with our devised instruments for the former subject and with a thermocouple for the latter. A simple analysis of the lip temperature obtained was made in order to know a mechanism of the lubrication. The results indicate that with the rise of temperature of oil seal, the wringing force and the average wringing pressure decrease because of the reduction of rubber elastic modulus and of thermal expansion of spring, and the lip contact width hardly varies, and also indicate that under a constant temperature of lubricating oil, the lip temperature never rises so high as in the case of free rising of oil temperature, and that the fluid lubrication is carried out at the lip. |
