Abstract The ring opening of epoxide group in the reaction of ethyl ,β-alkylglycidates with sodiomalonate was observed mostly at the α-position of the glycidates. Ethyl β-ethylglycidate, however, on treatment with sodiomalonate gave ten percent of β-fission product, elucidated by NMR spectra. The reaction sequence provides a general preparative route to γ-alkylparaconic acids and their derivatives.

Abstract The reaction of ethyl γ,γ-dialkylparaconate with aromatic aldehydes, i.e., benzaldehyde, anisaldehyde, p-chlorobenzaldehyde, and piperonal, has been investigated. The condensation took place at the α-position of the lactone ring. As the acidic components, α-benzylideneparaconic acids and α-benzylidene-β-alkylidensuccinic acids were obtained in 25-48% and 7-15% yields, respectively. From the neutral portions small amount of ethyl benzylideneparaconates were separated. During the course of distillation ethyl α-benzylideneparaconate was partially converted into α-benzylidene-γ-methy-γ-ethylbutyrolactone.

Abstract 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.

Abstract The method for continuous measurement of the high temperature heat content, developed by W.Oelsen et al. and applied to the glasses by M.Tashiro, was examined and modified in some points. Relations between the temperature and heat contents referred to the standard temperature 25℃, were determined for the some glasses of R(2)O-SiO(2) system, and the specific heats as well as the entropies were calculated. Comparing the results, some views have been obtained relating to the effect of the species and content of alkali ions on the thermodynamic quantities of such glasses.

Title Alternative A REPORT ON THE DEGREE OF SATURATION OF SPRING SOURCES IN TOTTORI HOT SPRING.
FullText URL 006_039_045.pdf
Author Mifune, Masaaki|
Abstract 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.

Abstract 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.

Abstract 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.

Abstract 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.

Abstract The optimum temperature in a sequence of two stirred tanks is considered subject to inequality constraints. For an illustrative example this nonlinear programming problem is solved using the SUMT method of Fiacco and McCormick, which transforms the constrained problem into a sequence of unconstrained minimization problems. The results are presented for several cases, and are fairly good.

Abstract 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.

Abstract 0.005r of paladium is detectable by the dithizone chromatographic method. Its absorption band is bluish green and situates between the brownish purple hand of nickel and violet band of cobalt. A micro amount of paladium, such as contained in rocks, can be determined by the dithizone chromatographic method. Interfering ions are eliminated by the combination of copper sulfide and nickel dimethylglyoxime methods. Analytical methods of paladium, nickel, cobalt, and copper by paper chromatograph were investigated.

Abstract 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.
