Title: Preparation of spherical hydrogen storage alloy and nickel-hydrogen battery using the storage alloy
Inventor: GERARD FRIEDELMAYER
IPC: C22C1/00
Filed: 1998-05-29
Abstract: PROBLEM TO BE SOLVED: To obtain a hydrogen storage alloy electrode for a nickel-hydrogen battery with the attenuation of the capacity as the cycle elapses suppressed and the rate characteristic improved by dripping a heated and melted hydrogen alloy base metal on a rotating metallic wheel to make it into spheres. SOLUTION: A hydrogen storage alloy rich in Mg components such as Mg, Mg2 Ni and Mg2 Cu is heated, melted and dripped on a rotating water-cooled metallic wheel in an inert gas atmosphere. As a result, a crystalline or amorphous spherical hydrogen storage alloy having a microstructure of <=500 μm grain diameter on the surface is obtained. The electrochemical activity is improved by this spherical alloy powder, the pulverization due to the swelling and contraction because hydrogen is stored and discharged is prevented, hence the service life is prolonged, and the capacity is increased by packing it in a high density. A high-performance nickel-hydrogen battery is composed of a negative electrode with the hydrogen storage alloy as an active material, a positive electrode with nickel oxyhydroxide as the active material and an aq. alkali metal soln. as an electrolyte.

IPC: H01L29/73
Filed: 1986-06-27
Abstract: PURPOSE:To prevent a soft error from being produced by alpha rays by forming an emitter layer on the side of a substrate and a collector layer on a surface. CONSTITUTION:After an undoped AlGaAs layer 11 and undoped GaAs are formed on a semi-insulative GaAs substrate, Si ions are implanted in regions 15 and 16 to be an emitter. Then, ramp annealing is performed to activate Si atoms. Then, an uppermost GaAs layer used as a protective film for the layer 11 is thermally decomposed in an MBE chamber. Then, a p-type GaAs layer 12 containing Be is formed and an n<-> collector layer 13 containing Si and then an n-type GaAs collector layer 14 containing Si are formed. Thus, since the inflow of hole and electron pairs due to alpha particles flowing into the collector layer can be prevented, the alpha ray soft error of an SRAM can be reduced by four figures as compared with the conventional.
