Patent JP-S63241860-A (JP)
Title: Alkaline zinc battery
Inventor: HAYASHI AKIRA
IPC: H01M4/06
Filed: 1987-03-30
Abstract: PURPOSE:To reduce gas generation at less consumption of mercury by keeping amalgamation ratio at a minimum level of zinc alloy powder inside a negative electrode gel body, and selectively amalgamating zinc alloy powder particles located in the vicinity of a separator. CONSTITUTION:A negative gel body 4 is prepared by mixing very low mercuric chloride zinc alloy powder, alkaline electrolyte solution and gelation agent with a specific ratio. The zinc alloy powder in alkaline zinc battery has 50-500 ppm of amalgamation ratio. Only the zinc alloy powder particles, in the vicinity of a point 4' which in contact with a separator 3, has 0.5 wt.% of mercuric chloride, a higher concentration than other places. If the amalgamation ratio is higher than 500 ppm, the voltage vibration phenomenon and deterioration with elapsed time in storage are resolved but the hydrogen generation rate disadvantageously increases. On the other hand, if the concentration is lower than 500 ppm, though the hydrogen generation rate is suppressed, the reliability declines because of the voltage vibration phenomenon and deterioration of the very low amalgamated zinc alloy powder with elapsed time in storage.

Title: Display device for camera
Inventor: YONEDA OSAMU
IPC: G03B17/18
Filed: 1980-06-03
Abstract: PURPOSE: To eliminate the failure in flash photographing that occurs on account of a photographer's false recognition by forcibly disabling a display element for flash emission permission display when the source voltage on camera side drops below a prescribed value.  
     CONSTITUTION: When the voltage of the power source EA 1  of a camera side circuit A lowers below a prescribed value, the voltage divided by resistances R 5 , R 6  by the power source A 1  is smaller than reference voltage ES and therefore a comparator A 1  generates an L level output. Hence, the currents from constant current sources 5, 6 are sucked into the comparator A 1  through diodes D 2 , D 5  and transistors TRQ 3 , Q 4 , Q 9 , Q 11  are forcibly turned off. When the TR Q 4  goes off, an LED 1  goes off, thereby displaying that photographing is infeasible. When the TR Q 11  goes off, no more current from an electronic flash device side circuit B flows to an LED 2  and therefore, the LED 2  is also forcibly put out. This eliminates the photographer's false recorgnition that flash photographing is feasible.

Title: Peak value tracking device
Inventor: KUBO HIROTSUGU
IPC: H03M1/18
Filed: 1989-03-29
Abstract: PURPOSE:To suppress generation of malfunction of a phase synchronizing device by varying a frequency division ratio of an operating clock generating circuit for a peak detection circuit and in a sampling pulse generating circuit according to a phase control signal through the use of a frequency division ratio deciding circuit. CONSTITUTION:A frequency division ratio deciding circuit 5 has a counter C counting a phase control signal generated between adjustment timings to calculate D=CmodM3 and E=CmodM1. Then the frequency division ratio for a signal outputted to a sampling pulse generating circuit 8 only for a period when the adjustment timing is inputted is changed from M3 into M1+D, while the frequency division ratio outputted to an operating clock generating circuit 4 is changed from M1 into M1+E. Thus, since the frequency division ratio is increased only at the adjustment timing, no problem takes place in the operation of the hardware. Thus, a timing error to be caused due to a shifted sampling pulse is solved by deviating the operating clock similarly.
