摘要： PURPOSE:To eliminate fluctuation in electrical resistance for a long time in service so as to obtain stable and high charging efficiency by forming both of a positive electrode and a negative electrode of sulfur and sodium respectively, and joining the outer circumference of a metallic container containing both of said materials with a bus-bar made of Al using an Al insert. CONSTITUTION:Pure Al is used as electrode terminal member 7, wherein no increase in an oxide film at temperature in service of 330 deg.C is allowed while electrical resistance is smaller that that of materials in an iron series, which is roughly one tenth of said material in this case, so that the electrode terminal member 7 is joined with a metallic container 6 by the use of an insert member in an Al-Si series. Thus, since Al small in electrical resistance is used as the electrode terminal, and moreover, connection is sufficiently made with a positive electrode container by the use of the Al insert member, electrical resistance between joint surfaces is extremely small, and there is no sign for an increase in electrical resistance due to temperature in service held for a long time. By this constitution, the charging/discharging efficiency of a battery is enhanced, and the reliable electrode terminal can be obtained.

摘要： PURPOSE:To obtain bonding substance excellent in corrosion resistance by using glass which has thermal expansion coefficient being smaller by 1-10X10 / deg.C than the thermal expansion coefficients of alpha-alumina and B''- alumina. CONSTITUTION:A solid electrolyte beta''-alumina to be 2 is arranged at the inner periphery of an alpha-alumina ring 1 for electric insulation, and glass powder is applied in slurry conditions, and is heated in the air so as to form a glass, with which those are joined together. In case that the thermal expansion coefficient of the glass is smaller than those of both aluminas, compressed stress remains at the surface of the glass after joining, and it improves the strength of the bonding substance. But, it if becomes too small, cracks occur inside the glass, which lowers the strength, so favorable strength and airtightness can be obtained within the range that the difference between both thermal expansion coefficients is 1-10X10 / deg.C. The glass, which has the above- mentioned thermal expansion coefficient, can be achieved by using glass in composition of 50-60mol% SiO2, 27-40mol% B2O3 and 10-13mol% Na2O from wettability, bonding property, etc., on limiting SiO2 to a maximum of 63mol% from corrosion resistance.

摘要： PURPOSE: To provide a turbo-machine and its anticorrosive treatment method capable of improving the corrosion resistance of a clearance part of a fitting part and a chrome plating part even if the oxygen process method (CWT) is employed for the water supply process method and maintaining and improving the durability against the corrosion fatigue even if seawater leak is generated. CONSTITUTION: In a turbo-machine provided with a shaft, impeller 1 and casing, a anticorrosive diffusing layer formed by the heat treatment of an anticorrosive diffusing material is formed on the surface of the mother material of a fluid path. A nickel alloy such as Ni-P, Ni-Si or Ni-B alloy is used for the anticorrosive diffusing material. Thus, the high dimensional accuracy can be maintained without changing the quality of the mother material while the corrosion resistance of the turbo-machine can be improved. Even if the oxygen process method (CWT) is particularly employed for the water supply process method, the corrosion resistance of a clearance part of a fitting part and chrome plating part can be improved and even if seawater leak is generated, the durability against corrosion fatigue can be maintained and improved.

CONSTITUTION:A pressure reception cover 8, two separation chambers 2 which are covered with a diaphragm 6 provided at a pressure reception part 1, and a pressure guiding path 3 for guiding the pressure of the other separation chamber to a pressure sensor 4 installed in one separation chamber are formed, the differential pressure between both pressure reception chambers 5 is detected, and then it is transferred to the outside by a transfer circuit 7. The diaphragm 6 is mounted to the pressure reception part 1 by a mounting part 10 and a groove 11 for preventing clearance corrosion is provided near the mounting part 10. Then the atmospheric pressure and the pressure of a measuring fluid are applied to the pressure reception chamber 5 and then the resistance of a sensor 4 according to the pressure of the measuring fluid is detected to measure the pressure. Also, by providing the groove 11, uneven concentration operation of a dissolved constituent within a liquid solution causing clearance corrosion to occur is prevented, thus suppressing the occurrence of clearance corrosion.
