IPC: G01R31/26
Filed: 1979-08-29
Abstract: PURPOSE: To enable to measure the turn-off time of the sample thyristor, by parallel connection of the active element having the switching capability of ON/OFF by itself to the diode in series connection with the sample thyristor.  
     CONSTITUTION: GTO31 or electrostatic induction type thyristor, or bipolar transistor 32 are connected in antiparallel to the diode 4. With the active element 31 or 32 ON, the inverse voltage is not fed to the diode 4 and with the active element 31 or 32 OFF, OFF voltage can be fed to the sample thyristor. Accordingly, even with the difference among thyristors to be tested for the turn-off time, the turn-off time can be measured without replacing the diode 4.

Filed: 1986-05-16
Abstract: PURPOSE:To enable an electrochromic layer to color sufficiently even at a fast write speed by holding a conduction state long as compared with the writing speed. CONSTITUTION:A voltage from a driving part 10 is impressed between a lower electrode 2 and the 2nd transparent electrode 7 and a pen 30 is pressed against an elastic transparent film 8. Then, transparent electrodes 6 and 7 facing the pressed part contact each other and the lower electrode 2 and the 2nd transparent electrode 7 become conductive to each other to inject charges into the electrochromic layer 4, which begins to color. The elastic transparent film 8 does not restore itself to the original state even after the pen 30 moves, the contacting state between the transparent electrodes 6 and 7 continues for a certain time T2, and then the film restores itself to the original state gradually by its elasticity. The injection of charges into the electrochromic layer 4 is not determined unconditionally by the motion of the pen 30 and the apparent contacting time is extended by the mechanical design conditions of the elastic transparent film 8.

Filed: 1991-05-17
Abstract: PURPOSE:To easily set the sectional area of the gate part of a metal mold, by releasing a runner and a package by cutting a gate with a cutting tool. CONSTITUTION:A gate 4 is cut with a cutting tool 3, thereby releasing a runner 5 and a package 8. For example, a lead frame 1 wherein resin sealing is finished is fixed with a lead frame clamp 2.
