Title: Piezoelectric transformer
Inventor: SHINDO SHOTARO
IPC: H01L41/08
Filed: 1987-12-17
Abstract: PURPOSE:To increase voltage and a current output without elevating applied voltage on the primary side by applying comparatively low voltage to an actuator and generating high voltage in a piezoelectric body block. CONSTITUTION:When primary voltage is applied to an actuator 2 through leads 14, 15 from a power supply 5, the actuator intends to elongate in response to applied voltage, but pressure is applied to piezoelectric body blocks 3, 3' because the actuator is regulated by a frame body 1, and the piezoelectric body blocks receive compressive stress. Consequently, the secondary signal of high voltage can be acquired through leads 16, 17, 18 from both ends of piezoelectric bodies. According to such constitution, output extracting surfaces in the piezoelectric body blocks can be spread, thus obtaining currents larger than conventional devices.

Title: Method of activating hydrogen storage alloy for battery, and activating solution
Inventor: MORISHITA SHINYA
IPC: H01M4/26
Filed: 1995-11-15
Abstract: PROBLEM TO BE SOLVED: To form an activated surface having a metal catalyst layer and containing less oxide on the surface of a hydrogen storage alloy for battery by setting the dissolved oxygen quantity of activating solution less than 0.1ppm. SOLUTION: In the activation of the surface of a hydrogen storage alloy, the dissolved oxygen quantity of activating solution is set less than 0.1ppm. Thus, in the surface of the hydrogen storage alloy, an oxide layer is eliminated, and Mm, Co, Al, Mn or the like is also eluted to form an activated surface. A metal such as Ni hardly eluted to alkali is left on the surface of the hydrogen storage allay to form a metal catalyst layer. Namely, since the dissolved oxygen is extremely lessened in the activating solution, the eluted metal such as Mm, Co, Al, Mn or the like is prevented from being reacted with the dissolved oxygen to precipitate a large quantity of oxide again on the surface of the hydrogen storage alloy. Thus, the activated surface having the metal catalyst layer and containing less oxide can be held by the activation.
