Patent JP-H0251857-A (JP)
Title: Manufacture of cadmium plate for alkaline storage battery
Inventor: MATSUI KAZUHIRO
IPC: H01M4/28
Filed: 1988-08-11
Abstract: PURPOSE:To improve the utilization factor of active material and largely improve the cycle characteristic by causing sufficient nickel hydroxide to exist in a cadmium plate through causing the plate to contain the nickel hydroxide after baking process. CONSTITUTION:A first step wherein a sintered porous nickel base is filled with cadmium hydroxide by chemical impregnation process to fabricate a plate, a second step wherein said plate is baked at a temperature not lower than 200 deg.C, and a third step wherein said plate after the baking is caused to contain nickel hydroxide, are comprised. Because the nickel hydroxide is caused to be contained after the baking process, the nickel hydroxide will never chemically change into nickel oxide. Therefore, sufficient nickel hydroxide exists in the battery so that the discharging reaction of the cadmium hydroxide, which is the anode active material, can be sufficiently promoted. Thus, the utilization factor of the active material can be increased and the cycle characteristic can be improved largely.

By the appropriate arrangement of the light receiving elements 34, the signals of different amplitudes are outputted to the respective elements. A signal level is detected in a signal level meter 32-2, the light receiving element 34 capable of obtaining the maximum amplitude is selected and a changeover switch 32-1 is controlled.  As the result, the output signals of the large amplitude are inputted to the optical communication equipment 30.

Filed: 1989-08-03
Abstract: PURPOSE:To smoothen the discharging of recording medium and prevent vibration, delivered from, a driving unit for discharging to the recording medium, to improve the quality of a picture by a method wherein the driving unit for discharging is set into non-driving condition and a clutch is set into power transmitting condition upon recording to drive a main roller and a discharging roller by a driving unit for recording. CONSTITUTION:Upon recording, a discharging motor 41 is set into non-driving condition and a recording motor 31 is set into driving condition while a solenoid clutch 38 is set into power transmitting condition. Accordingly, a main roller 13 and a discharging roller 15 are driven with an equal peripheral speed by the recording motor 31.
