Abstract Polyethylene was crytallized from the molten film under temperature gradient. As a result, the optically positive spherulites were observed, though only the negative spherulites had been observed previOusly in polyethylene. When the radial structure units twisted regulary in a spherulite are formed parallel to the surface of the film, the spberulite is usually optically negative in polyethylene. In this study, the temperature gradient normal to the surface of the film gives so significant tilt of the radial structure units formed to the surface of the film that the radial refractive index becomes larger than the tangential one under the transmitted polarized light and the spherulites have optically positive behavior. The optical behaviors of the polyethylene spherulites and the crystallizing condition were studied and discussed.

Abstract It was shown that the fibrous crystals of isotactic polybutene-l crystallized from solution under shearing stress are also composed of the central threads with an extended chain character and the epitaxally deposited lamellae with a folded chain character. The characteristic behaviors in this polymer exist in; (1) that the resulting crystals possess the hexagonal modification of form 1'; (2) that at low polymer concentrations the lamellar crystals with an orthorhombic modification of form Ⅲ are precipitated in similar fashion to the case in the absence of stirring; (3) that the morphology in surface replica of thick deposited film is very similar to that of melt extruded polyethylene film crystallized in a highly stressed state.

Abstract Isotactic polypropylene was crystallized in the form of fibrous crystals from solution under shearing stress. The fibrous crystals consist of the oriented cluster of micro fibrils. From the electron microscopy and the electron diffraction study, it was found that the fine texture of this fibrous crystals is also the two component systems which are composed of the central threads with an extended chain character and the lamellae with a folded chain character deposited on the threads, as in polyethylene. Relatively larger lamellar structure than that of polyethylene was observed. The effect of crystallization conditions to the formation of the fibrous crystals from solution of isotactic polypropylene was described briefly. A characteristic melting behavior due to the melting of the central threads with an extended chain character was observed from the thermogram of differential scanning calorimeter.

Abstract Monoamides of 5-substituted 4-methyl-3-carboxy-3(or 4)-alkenoic acids have been synthesized, starting with substituted itaconic anhydrides. The anhydride ring was opened by amines to afford N-aryl(or alkyl)-4-alkyl(or aryl)-3carboxy- 3(or 4}-alkenamides. The structure of the amide was elucidated by the comparison with the reference compound prepared from the corresponding Stobbe half-esters.

Abstract Spectrophotometric investigations were carried out on soda-lime-silica glasses containing iron in high content, corresponding to 4.9 wt.% Fe(2)O(3), and melted under the various reducing conditions, as a part of series of studies on the redox behavior of glass. Absorption measurement was made in the range from 340 mμ to 1000 mμ. Ferric ions could not be reduced to ferrous ions completely even by the amount of carbon of four equivalents. The ratio of the strength of light absorption at 1000 mμ as a typical band of Fe(2+) ions and that at 380mμ of Fe(3+) ions was expressed as E(1000)/E(380), which was examined for glass compositions as well as various carbon amount added to glass batches. The ratio decreases as the carbon amount increases and increases with decreasing content of Na(2)O or CaO. These changes of spectrophotometric properties of glasses were discussed from the view point of state of the the iron ions. Besides, some results on oxidized glasses were also added.

Abstract The liquid phase mass transfer resistance in the Rotational-current tray is one of the most important factors in its design and performance. In this report, the holding time of liquid on the tray was studied experimentally by water-air system, and then the desorption tests were carried out by water-oxygen-air system that the liquid phase resistance were controlling. From the results of these experiments, it was found that the gas flow rate and the holding time of liquid on the tray control the tray efficiency strongly. Thus, the experimental equation for the number of transfer units based on liquid phase was derived. And also, it was found that this type of tray can be operated at high efficiency with a higher gas rate than the Kittel tray and the sieve tray without downcomer.

Title Alternative STUDIES OF THE RADIO-ACTIVE SPRINGS (XXXII) EFFECTS OF THE RADIO-ACTIVE THERMAL BATH ON CIRCULATION SYSTEM (2nd Report)
FullText URL 008_024_050.pdf
Author Onoda, Susumu|
Abstract a)The author studied the changes in the activity of choline'-esterase (ChE) in serum, before and after a radio-active thermal bath (43℃,5min.)in Misasa, and their seasonal differences. The results were as follows: (1) The ChE activity in human serum was stronger in winter than in summer. (2) The ChE activity was reduced after the thermal bath, and the decrease was more marked in winter than in summer. b) The author proved by Laewen-Trendelenburg's method that fresh radio-active thermal water of "Yamada-Ku-Kyodo-Yu" in Misasa dilatates the blood-vessel, but the same water, stored for weeks, constricts the vessel. Under the author's experimental conditions the dilatating effect of the radio-active spring waters proved to become stronger as their radon content increases. The freshly taken Yamada-Yu water inhihited the action of Adrenaline or Imidaline (a benzyl-imidazoline derivate), but the aged Yamada-Yu water showed no such antagonistic action. c) Blood circulation time, measured with vitamine B(1), was reduced after the thermal bath, but the changes showed no significant difference between the radio-active thermal bath and plain water bath. d) The height of waves of the electrocardiograms in healthy persons increased more after the radio-active thermal bath than after the plain water bath in general. The increase was higher as the temperature of bath rises, but the difference between the kinds of baths was not significant. In chronic rheumatism and hypertension patients the increase was slight, and in some cases a remarkable fall of ST was recognized after the radio-active thermal bath at 40℃ for 10 minutes. QRS shortened slightly in Wilson's lead. After a bath at 40℃ for 10min., lowering of the minimal blood pressure was not so marked than after a bath at 43℃ for 5min., both in healthy and diseased persons.

Abstract Al-Zn, Al-Ag and Al-Cu base ternary alloys were studied by measurement of electrical resistivity. An approximate methods to estimate the binding energy between an atom of a third element and a vacancy was derived. The binding energy between a vacancy and an atom of Cu, Ag, Au, Be, Ca, Cd, In, Si, Ti, Ge, Zr, Sn, Pb or Mn was estimated to be <0.23, 0.25,> 0.35, 0.28, 0.27, 0.32, 0.39, 0.28, 0.30, 0.33, 0.33, 0.43, >0.38 or <0.23 (±0.05) eV, respectively. The results may be summarized as follows: (I) The ratio of the time required to reach the maximum electrical resistivity in isothermal aging curves of the Al-Zn-X or Al-Ag-X ternary alloy to that in the Al-Zn or Al-Ag binary alloy may be inversely proportional to the ratio of the concentration of vacancies bound to Zn or Ag atoms immediately after quenching in the ternary alloy to that in the binary alloy. And also the ratio of initial rate of clustering for AI-Cu-X ternary alloy to that in the binary alloy may be inversely proportional to the ratio of the concentration of vacancies bound to Cu atoms immediately after quenching in the ternary alloy to that in the binary alloy. It is possible to deduce the binding energy between an atom of X element and a vacancy using this relations. (2) The effect of the valence of the solute element on the binding energy between an atom of a third element and a vacancy was remarkable. (3) The effect of the radius of an atom of the solute element on the binding energy is also observed, but this effect is smaller than that of the valence.

Abstract This study is concerned with a developed method for obtaining the quantitative relations between the input or output characteristics and the geometric parameters of the wall reattachment fiuidic devices. In this report, it is shown analytically and experimentally that the characteristics can be represented by the functions, dependent on the geometric parameters only, with non dimensional quantities, if the Reynolds number at the main jet nozzle is sufficiently large. Accordingly, the quantitative relations of the geometric parameters may be analyzed more easily.

Abstract Yanahara Hot Spring is one of the strongest acid vitriol springs in the world. It contains 0.36 g of free hydrogen ion, 14.6 g of ferrous ion, 0.8 g of ferric ion, and 0.44 g of copper in one liter. Its internal use has an remarkable effect on the recovery of hypochromic anaemia. Ten ml of this vitriol water was diluted with plain water to two hundred ml and was given to twenty six patients by stomach tube at 37℃. Gastric acidity of the patients was measured at thirty minutes intervals during the following 150 minutes after the administration of the water. In seven cases of normoacidity no significant difference was proved between the effects of the mineral water and of caffeine control (0.2 g in 200 ml.). In ten cases of hyperacidity a marked decrease in the free gastric acidity curve was recognized by the use of the mineral water compared with caffeine control. In nine cases of hypo- and anacidity both free and total acidity curve was elevated by the use of the mineral water compared with the curve of caffeine control.

Abstract This paper deals with the optimization problem of extraction processes with recycle and immiscible solvent. Gradient methods using control variable iteration require a trial and error procedure to solve process and overall equations for this problem. A new formulation is presented to eliminate such a trial and error procedure. First order and second-order convergence gradient methods were applied to determine the optimum solvent distribution in cross-current extraction with recycle and immiscible solvent. The Fletcher-Powell method converged most rapidly in all cases.

Abstract The measurement of the flicker value is a method to estimate the degree of the fatigue. This method is investigated by several authors. (1),(2) The control chart of the flicker value was used for one method of the labor management and found that this chart showed the learning trend. In this paper, the simulator of automobile was used to examine the relation between the variation of the flicker value and the driving environment, the learning process of the reaction and the relation between the flicker pattern and the learning process in the working hours. These were contributed to find the beginning of the stationary condition and which group was adapted to this work. Data was analyzed by statistical methods. It was found in this study that the variation of the flicker value and the learning process of the reaction were connected with each other.

Abstract The friction coefficient of sectionally rough pipes has not been studied yet. The friction coefficient for turbulent flow through sectionally roughened square ducts is experimentally studied. Four arrangements of rough surfaces are used to obtain the sectionally roughened square ducts. It is attempted to predict the friction coefficient for sectionally roughened square ducts from the friction coefficients for alloverly roughened and smooth square ducts.

Title Alternative STUDIES ON VITRIOL SPRINGS (9) EFFECT OF THE INTERNAL USE OF VITRIOL WATERS ON THE IODATE CONSUMPTION OF BLOOD.
FullText URL 008_013_017.pdf
Author Sotozono, Masazumi|
Abstract Oshima proved that blood catalase level tends to decrease after the internal use of the vitriol waters of Yanahara and Fujino and explained his data by the promotion of oxidative process in the body by the waters. Consumption of iodate by proteinfree serum filtrate is an index of total reductive substances in serum. After the internal use of these two mineral waters, this index increased temporarily, but there was no significant difference between the effects of the two mineral waters and of plain water. In anaemic patients this index tends to decrease after successive daily intake of Yanahara vitriol water in accordance with the recovery of anaemia.

Abstract Broadly speaking, there are three kinds of approaches to investigate the deformation and fracture of materials, that is, the microscopic (metallurgical), macroscopic(mechanical) and theoretical (mathematical) researches. It is necessary, however, to bridge the gap which persists among of them. Many investigations on the form of plastically deformed zone at a crack tip, the distribution of plastic strain in plastic zone and fracture criterion have been made for the purpose to clarify the mechanism on initiation and propagation of cracks. In this paper, the authors report the studies, from the standpoint of microscopic views, on the crystal deformation at the tip of crac's in notched specimen during fatigue process.

Author Yokota, Takeo|
Abstract Using Na(2)SO(4) labeled with S(85) transition of sulfate ion into the body across the skin was investigated soon after the bath in sodium sulfate solution(one gram per liter) at varying conditions. Mice were used as test animal. Percutaneous absorption of sulfate ion was promoted at indifferent bath temperature (37℃) than at lower bath temperature (25℃), became less by the addition of sodium chloride (one gram per liter) to the bath water, proved stronger at lower pH (2.0) than at higher pH (7.0 or 9.0). One of the characteristic types of mineral waters in Japan is "acid spring". And many of the Japanese acid springs contain free sulfuric acid in considerable quantity.It is known that their bath cure often causes dermatitis, socalled "Yutadare". Misawa and Oshima had proved that the level of immune bodies in blood is increased by the bath cure with dermatitis in acid springs of "KUSATSU". And the author's experiment seems to give a new significance to the ro1e of sulfate ion in the action of acid spring bath in Japan.
