Title: Gate driving circuit for voltage-driving type semiconductor element
Inventor: MARUYAMA KOJI
IPC: H02M7/483
Filed: 1999-05-11
Abstract: PROBLEM TO BE SOLVED: To prevent element destruction and reduce generated loss at the time of re-ion by causing re-ion of a voltage driving type semiconductor element where over-voltage is applied, and setting the gate voltage of re-ion to the voltage level of around the threshold value of the element. SOLUTION: When Q1 is first turned off, for example, the voltage detected by detection resistor as well as the collector-to-emitter voltage CCE of Q1 reaches an over-voltage detection level, which is discriminated as over-voltage by an over-voltage discriminating circuit. As a result, a re-ion circuit comes into action to cause re-ion of Q1. The collector-to-emitter voltage VCE of Q1 drops, therefore over-voltage can be prevented from being applied to Q1 during the time Δt necessary to turn off Q2. The gate voltage VGE of Q1 is controlled so as to be around threshold value of Q1, so that repetition of re-ion operations can be prevented, thus it is possible to reduce the loss of Q1.

Title: Two-color electrophotographic copying method
Inventor: SAKAI TOSHIO
IPC: G03G13/01
Filed: 1977-10-28
Abstract: PURPOSE: To improve the color separation characteristics of images by controlling the potentials of an evenly charged recording medium to specified values with light of the original colors and subjecting the unexposed parts to required development processing.  
     CONSTITUTION: A recording medium 1 is evenly charged at a potential V 0  by a charger 2. Next, when the red part of the original is exposed by using a filter FR which transmits only the red light, the developable charge potentials V 1 , V 0  of the exposed and unexposed parts of the medium 1 become V 1 <V 0 . If bias voltages satisfying the conditions of V 0 >VB>V 1  are applied to the medium 1 and development processing is performed with opposite polarity toners TBL, then only the unexposed part of the medium 1 corresponding to the black part of the original is processed. Similarly, when exposure is performed by using a filter FB which transmits only the black color and development processing is done, then only the red part of the original is processed, thus the two-color images of good color separating characteristics may be formed.
