Title: Electronic clock with illumination
Inventor: FUJIMORI MOTOYUKI
IPC: G09G3/00
Filed: 1979-05-29
Abstract: PURPOSE: To provide an electronic clock with illumination which permits reading an display of time at a low power consumption, by adapting illumination to be lit automatically at predetermined intervals within a predetermined period of time.  
     CONSTITUTION: Switches 7, 8, 9 are externally operated to memorize desired time for turning on a light 11 in a memory circuit 13. When the memorized time and the time on a time counter 4 agree with each other 14, a light controlling and energizing circuit 12 is turned on to allow the light 11 to be automatically lit. A light energizing time is set in a timer 15, and a light-energizing pattern memorized in a memory circuit 16, in which various-energizing time dividing patterns are memorized, is selected so as to divide the time set in the light-energizing timer 15. Thus, the light 11 is automatically lit by actuating the light controlling and energizing circuit 12.

Title: Tester for electronic device
Inventor: YOKOYAMA EIJI
IPC: G01R27/28
Filed: 1986-03-26
Abstract: PURPOSE:To shorten a test time and to prevent malfunction from occurring by providing an oscillator, a rectifying and smoothing circuit, an A/D converting circuit, a control and arithmetic means, etc. CONSTITUTION:The variable frequency type oscillator 1 sends its output to an electronic device 2 to be inspected. The rectifying and smoothing circuit 7 rectifies the output of the electronic device 2 on full-wave basis to generate a DC level and the A/D converting circuit 5 converts the output of the rectifying and smoothing circuit from analog to digital. Then, the control and arithmetic means 6 sets the oscillation frequency of the oscillator 1 and also sets a sampling period corresponding to the set oscillation frequency in a sampling circuit. Namely, the sampling period is shorter and shorter and the frequency of sampling is larger and larger as the set oscillation frequency is lower and lower. For the purpose, all sampled values are averaged and the mean value is equal to the value when a capacitor is switched. Namely, electrostatic capacity need not be increased, so the time up to the stabilization of the output level of the rectifying and smoothing circuit is shortened in the beginning of the oscillation of the oscillator.
