Title: Manufacture of hydrogen storage alloy electrode
Inventor: ISE TADASHI
IPC: H01M4/26
Filed: 1997-01-30
Abstract: PROBLEM TO BE SOLVED: To provide a metat hydride storage battery with excellent initial inside pressure characteristics and highly rated discharge characteristics in its initial stage, by treating a surface of hydrogen storage alloy in acid solvent containing not less than one king of ion selected from a group of ions such as aluminum ion, galium ion, etc. SOLUTION: A surface of hydrogen storage alloy is treated by acid solvent containing at least one kind of ion selected from a group of aluminum ion, galium ion, indium ion and tarium ion. By this surface treatment, while a reaction surface area of the alloy is increased, the surface of the alloy becomes a layer rich with nickel. Besides this nickel-rich layer acts as a catalyst for absorbing and discharging reaction of hydrogen, it also becomes a catalyst for absorbing reaction of oxygen gas produced from a positive electrode when over charged. The surface of the hydrogen storage alloy is further etched by hydrolysis reaction of those ions, so that a reaction surface area of the alloy surface is further increased and the hydrogen storage alloy with high activity can be obtained.

Filed: 1989-01-26
Abstract: PURPOSE:To attain the remote supervisory and control by securing the input/ output state where the input side is set at a TTL level with the output side set at a CMOS level. CONSTITUTION:A comparator 2 and a CMOS buffer 3 are set at the input and output sides of an internal circuit 1 respectively, and the reference voltage of the comparator 2 is set via the resistors R1 and R2. Thus the input is attained for the TTL level (threshold voltage of 1.3V) of a bipolar. The protecting clamp diodes D1 and D2 are connected to the output side of the circuit 1. An internal constitution that can be attained with a gate array is secured in the case of realizing circuit integration. Therefore it is possible to obtain the input/output state where the input and output sides are set at the TTL level and the CMOS level respectively. As a result, the input/output noise margin is increased and furthermore the transmission speed is never lowered without waveform strain. Then the remote supervisory and control is attained with the improvement of the reliability.
