| Abstract | The microstructure of oxidizing magnesium at elevated temperatures has been studied using HR-TEM, SEM and EDS. Two kinds of thin magnesium specimen for TEM observation were prepared. One was oxidized after preparing TEM foil of magnesium, the other was prepared from an oxidized bulk magnesium for observing the cross-section of oxide/Mg interfacial region. In the former, several oxides(MgO) morphologies were observed depending on the temperature and time of the oxidization. The growth of needle-like oxides formed at 573K and mottled oxides formed at 773K were recognized as a remarkable phenomenon belonging to the local oxidization. These oxides were composed of poly-crystal. The thin uniform oxidization layer was also observed in all conditions. In the cross-sectional observation, the local oxide layer, nearly 300nm in thickness, on the matrix(Mg) were observed. The thin uniform oxidized layer of bulk samples was identified as a kind of modified layer (~40nm in thickness) in which the formation of HR-TEM lattice fringes were prevented by the strain due to the slight oxidization. |

| Abstract | At Sekigane Hot-Spring, Tottori, Japan, where three hot-springs place side by side, the auther measured the variation of spring temperature, pH, Cl,- HCO(3)- and SO (4)-- content and the amount of flow, during and after, pumping suction of one hot-spring. About the variation of other hot-spring, immediately after the commencement of suction, the content of HCO(3)- decreased and that of Cl- and SO(4)-- increased. Then the increase of HCO(3)- content and the decrease of Cl- and SO(4)--contents appeared with the lapse of time. After stopping the suction, these changes in contents were reversed agaln, that is, the decrease of HCO(3)- and the increage of Cl- and SO(4)-- were observed. Immediately after the second suction was begun, HCO(3)- increased and Cl- and SO(4)-- decreased rapidly. The amount of flow increased only when the pumping suction stopped. At the hot-spring which was pumped, HCO(3)- and SO(4)-- contents decreased and the slight increase was observed in Cl- content. Of cource, only when the suction stopped, the amount of flow decreased. But at these hot-springs, the ratio of Cl-/SO(4)-- has always constant value, about 1.05. These results show that these three hot-springs belong to the same line and difference was observed only in the contamination with ground-watres. |

| Abstract | In this study we investigated the water quality of surface runoff and groundwater runoff from the basins of the Yodo River and the Asahi River based on that separated by a numerical filter. The water quality of the surface runoff is greatly different from the groundwater runoff. The tendency of concentration change in accordance with river discharges is different from each other. The water qtiality of groundwater runoff changes with river discharges clockwise in many cases. The differences of COD and SS originating from those of population and industrial activities in each basin are found in the lower SS concentrations of the surface runoff and the COD cencentrations of the groundwater runoff. The nutrients and chlorine ion were investigated, too. |

| Abstract | Scribing of copper coated alumina ceramic board with Q-switched YAG laser used for the maskless direct patterning of circuit board is experimentally investigated, which leads to efficient production of trial circuit board. Better dividing of alumina circuit board 655μm in thickness can be attained by the scribing of about 100μm depth. Higher repetition frequency of laser irradiation leads to smaller notch angle and lower breaking load. |

| Title Alternative | BALNEOLOGICAL STUDIES USING RADIO-ACTIVE ISOTOPES (1) ON THE MECHANISM OF THE ACTION OF SODIUM SULFATE SPRING BATH． |

| Abstract | Using Na(2)SO(4) labelled with S(35) transition of sulfate ion into the body across the skin was investigated soon after the bath in sodium sulfate solution at varying conditions. Mice were used as test animal. Percutaneous absorption of sulfate ion proved to be promoted at high bath temperature (45℃) than at indifferent temperature(37℃). stronger by the bath of longer duration (30min.) than by the bath of shorter duration (10min.), increased after repeated baths than after a single bath. It was accelerated by making a burn to the skin of the bathed animals. Layton and Dziewiatkowski proved that the parenterally administered sulfate ion was partly fixed in the connective tissue as chondroitin sulfate. The author had proved that chondroitin sulfate relieves pain, increases peripheral circulation and when administered parenterally promotes production of immune bodies. In Japan natural and artificial Glauber's salt spring bath are known to have a beneficial effect on wound healing, but no satisfactory explanation was given till today. Lith reported that a hypertonic solution of sodium sulfate promoten wound cure by external application and Seki showed that subcutaneous connective tissue of mice was stimulated by the bath in sodium sulfate spring. And so the abovementioned author's data seem to throw some light on solving the problem. |
