摘要： PROBLEM TO BE SOLVED: To provide a sodium-sulfur secondary battery with excellent charge/ discharge characteristics. SOLUTION: An electronic conductive material 3 impregnated with sulfur is arranged in a positive chamber 9 formed between a battery container also serving as a positive current collector and a solid electrolyte tube 1, and a substance with high sulfur resistance and low electronic conductivity is stuck to between the solid electrolyte tube 1 and the electronic conductive material 3. Accumulation of sulfur attendant on charge/discharge cycles is prevented, and charge/discharge depth is stabilized. Sulfur deposition reaction on the solid electrolyte surface in the charging final stage is retarded, and charge depth can be increased. Battery performance is stabilized.

摘要： PURPOSE:To adjust the heat radiation from a vacuum heat-insulative layer and maintain the temp. variation of a battery within a certain range without resorting to a mechanical drive by changing the adsorbing ability of a gas adsorptive agent depending upon the temp. for the gas in the vacuum heat-insulative layer, and thereby regulating the degree of vacuum. CONSTITUTION:After a battery module 1 is heated by a heater 19 to the rated running temp., discharge is started, and when the internal temp. of a vacuum heat-insulative vessel 2 has risen, a controller 14 is actuated to allow a heater 7 to heat a layer 6 filled with a hydrogen storage alloy powder, and hydrogen is emitted so that the degree of vacuum of a vacuum heat-insulation part 3 is lowered. This also lowers the heat insulating performance to increase the amount of heat radiation, and the rise of the internal temp. of the vessel 2 is suppressed. In the charge operation, the internal temp. of the vessel 2 sunk, and the controller 14 is actuated to open a control valve 10 so that the layer 6 is cooled by a refrigerant 11, and the hydrogen absorbing ability of the alloy powder is increased to increase the degree of vacuum of the heat- insulation part 3, and the heat insulating performance is enhanced to suppress temp, sink of the vessel 2. Thereby temp. variation of the battery is suppressed, and the energy efficiency is maintained high.

摘要： PURPOSE:To reduce power loss significantly in a D/A inverter and to enhance the transmission efficiency by transmitting DC power, as it is, from a battery facility to a train. CONSTITUTION:Transformed AC power from a transformer 3 is inverted through a D/A converter 4 comprising a thyristor inverter into DC power. When power from the D/A inverter 4 is not fed to a battery facility 5 but fed through a DC transmission line 6 to a train 7, a switching element or a unit constitutes the battery facility 5. The circuit is switched for every group of a large number of batteries by switching the connection of external wiring of the battery facility. Since the output of power stored in the battery facility can be regulated, the battery power storage system can be operated efficiently through connection with a control system 10. Furthermore, since D/A conversion accompanied with high power loss is required only once for transmitting power to a train, high efficiency low loss transmission can be realized.

摘要： PURPOSE:To separate conveying fluid and heat accumulator by non-mechanical means, to separate heat source fluid and the conveying fluid and to bring the heat source fluid with the accumulator to be heat exchanged by holding magnetic fluid by varying an intensity of a magnetic field, arbitrarily altering an apparent specific weight, and dropping capsuled heat accumulator in the magnetic fluid. CONSTITUTION:Units 4, 5 for separating a heat accumulator by applying a magnetic field to magnetic fluid 11 are provided on the way of a transporting passage of heat accumulation medium 3 to be circulated through a heat accumulation unit 1 and a heat exchanger 2, and heat source fluid 9 from a heat source of the heat exchanger side is brought into direct contact with the accumulator 10. Only the accumulator 10 is dropped to be separated in the fluid 11 so regulated to a specific weight as to be heavier than a specific weight of conveying fluid 8 or heat source fluid 9 and lighter than that of the accumulator 10. Thus, since the accumulator of the medium is separated without damaging the accumulator without power by utilizing a difference of the specific weights, a system for bringing the heat source fluid from a waste heat source into direct contact with the accumulator to be heat exchanged can be easily constructed, thereby improving a recovering efficiency of low temperature heat.

摘要： PURPOSE:To reduce the cost and to improve the heat recovery rate by using the medium of a heat source and a heat storage tank as the carrying fluids of a capsule-shaped vessel respectively and circulating a capsule and the mixed fluid of the carrying fluids between the heat source and the heat storage tank while changing over two kinds of the carrying fluids. CONSTITUTION:Solid-liquid separators 5 are installed in front of a heat storage tank 6 and in front of a tank 3 for heat recovery, in which river water 1 and a capsule are mixed, and a capsule medium 7 and river water 1 or the capsule medium 7 and the medium 28 of the heat storage tank 6 are changed over and only the capsule medium 7 is circulated between the heat recover tank 3 and the heat storage tank 6. The heat of river water 1 is exchanged with the capsule medium 7 during carrying until river water is separated from the capsule from the tank 3 for heat recovery at that time, and the temperature of river water 1 is lowered up to approximately 5 deg.C and river water is returned to river. Consequently, a heating medium in the capsule is brought to a molten state, and the capsule is introduced into the heat storage tank 6. The heat storage tank 6 is filled with the medium 28 discharged from a heat pump 10 at approximately 2 deg.C, and the heat of the capsule medium 7 is dissipated to the heat-accumulating medium 28 and the capsule medium 7 is coagulated.

摘要： PURPOSE:To offer a heat-dissipating structure body which is small-sized and lightweight and whose heat-dissipating performance is excellent by a method wherein a sheet-like heat pipe is formed collectively between a face opposite to an LSI chip mounting face of an interconnection board and the bottom face of a radiating fin. CONSTITUTION:A heat-dissipating structure body of a semiconductor device is constituted of the following: an LSI chip 6; an interconnection board 1 on which the LSI chip 6 is mounted; terminal pads 2 to which leads of the LSI chip 6 are bonded; input/output pins 3; and a radiating fin 9 which is fixed and bonded to the interconnection board 1. A working fluid such as water, methyl alcohol or the like is sealed in a closed space which is composed of a hollow formed in the radiating fin 9 and of the surface of the interconnection board. Thereby, a sheet-like heat pipe 4 is formed between the interconnection board 1 and the radiating fin 9. Heat generated by the LSI chip can be conducted efficiently to the radiating fin by a heat transfer in the sheet-like heat pipe, and an excessive temperature rise of the LSI chip can be suppressed.
