Title: Manufacture of cadmium negative electrode for alkaline storage battery
Inventor: YAMASHITA KATSUMI
IPC: H01M4/44
Filed: 1987-12-04
Abstract: PURPOSE:To increase gas absorbency and to lengthen the life even at high temperature by gradually electrolyzing a cadmium active material coated plate in a specific nickel salt aqueous solution while current density is varied from high density to low density to form a thin nickel film on the cadmium active material. CONSTITUTION:Cadmium active material powder is applied to both sides of a conductive substrate, dried, and cathodically electrolyzed in a nickel salt aqueous solution mainly comprising nickel chloride or nickel sulfate while the current density is continuously varied by stages from high density to low density to form a thin nickel layer on the surface. By forming the nickel layer on the active material surface of a cadmium negative electrode, oxygen gas absorbency is increased by the metallic cadmium preferentially deposited in the vicinity of the surface of the negative electrode. Since the dense layer of fine metallic nickel is formed, the dissolution and diffusion of a discharge product at high temperature are prevented and the charge-discharge cycle life of a battery is remarkably increased.

Filed: 1989-11-28
Abstract: PURPOSE:To eliminate a lack of oil of a refrigerant compressor even in case of high speed operation of the refrigerant compressor by a method wherein a bypassing circuit is provided with a differential pressure valve to be opened when a pressure at a refrigerant evaporator is higher than a pressure at the refrigerant compressor by a predetermined value. CONSTITUTION:When a cooling compressor 2 is operated at a high speed, a differential pressure between a refrigerant evaporator 6 and a refrigerant compressor 2 is increased as its suction force is increased. As the differential pressure is more than a predetermined pressure of about 1kg/cm<2> a differential pressure valve 8 is opened. As a result, liquid refrigerant containing oil is flowed out of the bottom part of the refrigerant evaporator 6, the refrigerant may pass through an accumulator 15 and a bypassing pipe 16 and then the refrigerant is sucked into the refrigerant compressor 2. In this way, in the cycle 1, the refrigerant compressor 2 is operated at a high speed when the pressure adjusting valve 7 is operated, and in case that a lack of oil may easily occur, the liquid refrigerant containing oil is returned back from the bypassing passage 16 to the refrigerant compressor 2, resulting in that the lack of oil can be eliminated.
