Title: Electronic watch
Inventor: ONDA MITSUO
IPC: G04G99/00
Filed: 1978-10-03
Abstract: PURPOSE: To prevent the power voltage reduction to the heavy load only at the low temperature time by inserting the switch or the temperature-sensitive resistance element between the cell and the capacitor.  
     CONSTITUTION: Switch 7 is inserted between cell 5 and capacitor 6 and opened at the normal temperature. When switch 7 is closed at the low temperature, capacitor 6 is charged at the light load driving time in the electronic circuit 2 and the like of the watch. And the power voltage reduction according to the reduction of the inner resistance caused by the low temperature can be prevented for cell 5 owing to the discharge energy of capacitor 6 at the driving time of the heavy load of driving circuit 3 and the like. As a result, the consumption of the leak current is limited only at the low temperature, thus avoiding the undesired power consumption and accordingly ensuring good driving for the light and heavy load of the watch. The temperature-sensitive resistance element can also be used in place of the switch to obtain the same effect.

Filed: 1979-09-25
Abstract: PURPOSE: To realize a control of the electronic meter to a proper luminance in both the daytime and the night, by securing the minimum luminance of the electronic meter through a control given to the voltage level of the control pulse after detecting the daytime via the light switch.  
     CONSTITUTION: The daytime light switch 4 is turned off, which is detected by the daytime/night detecting circuit 54. Thus the transistor TR 4  is turned off in the circuit 54, and accordingly the transistor TR 5  of the night luminance lowering circuit 55 conducts. As a result, the Zener diode ZD 1  is short-circuited to give no function to the circuit 55. At the same time, the transistor TR 4  of the minimum luminance securing circuit 56 conducts, and thus the control pulse voltage which is applied during the duty 100% of the control pulse delivered from the illumination controller 1 to the center tap CT of the display power supply circuit 52 is secured by the Zener diode ZD 2  in accordance with the minimum luminance. In such way, the luminance of the electronic meter can be controlled properly in both the daytime and the night through the interlocking of the light switches.
