IPC: H01M4/52
Filed: 1989-02-02
Abstract: PURPOSE:To enhance the storage performance and cycling performance of a battery by using spherical nickel hydroxide powder as the additive. CONSTITUTION:A nonsintered cadmium negative electrode for an alkaline storage battery consists of cadmium oxide powder and/or cadmium hydroxide powder which is the main active material, metallic cadmium powder which is the preliminary charging material, and spherical nickel hydroxide powder which is the additive.

IPC: G03B19/12
Filed: 1986-02-10
Abstract: PURPOSE:To reduce shock or vibration generated from a light shielding plate by setting up a driving voltage to be supplied to a motor at the movement of the light shielding plate to a level lower than that of a driving voltage at the movement of a mirror. CONSTITUTION:After the interruption of work due to the completion of the movement of the mirror, a forward rotation signal is outputted again to a forward rotation signal output terminal 86a of a CPU 86. Consequently, a relay 90 is turned on, a contact piece 91 is connected to a terminal 91 and the motor 28 is forward rotated by a driving voltage applied to a point (c). Initially, the voltage is gradually increased in proportion to the voltage of a line 9a), and when it reaches the voltage of a line (b), its level is kept at a fixed value. Since load to rotate the light shielding plate is lower than a mirror rotating load, it is set up to a low level based on resistors 98, 99. The movement of the light shielding plate is detected by a photosensor 71 and the motor is stopped through the CPU 86. Thus, shock or vibration due to the movement of the light shielding plate can be reduced by successively moving the mirror and light shielding plate and changing their driving voltages.
