Filed: 1995-01-11
Abstract: PURPOSE: To reduce defective operation and current fluctuation and to stabilize operation by arranging a pair of resistors in a power semiconductor module(PSM) to be connected in parallel with another PSM and arranging a pair of resistors between both PSMs. CONSTITUTION: Gate resistors 14 (Rg1 , Rg2 ) are arranged in the vicinity of gate on respective IGBTs 13 (IGBT1, IGBT2) and a common gates resistor 14 (Rg0 ) is arranged in the vicinity of the outside of a part on which respective gates are connected in parallel. When the IGBTs 13 are switched by switching a gate signal by 2 to 10kHz high frequency, the resonation of gate voltage may be generated between the IGBT1 and the IGBT2 connected in parallel if the resistors Rg1 , Rg2 are not arranged. When the resistors Rg1 , Rg2 are added, turn-on and turn-off operation is slightly moderated but the resonation of the gate voltage can be suppressed. Since gate resistors Rg0 are added in the case of connecting plural modules in parallel, the resonation of the gate voltage can be effectively suppressed.

Title: Toner concentration control method
Inventor: TAKAHASHI ZENJI
IPC: G03G15/00
Filed: 1990-01-11
Abstract: PURPOSE:To prevent the blank part of paper already printed from being contaminated and printing density from lowering by dividing the level of the reference voltage of a comparator into plural levels, comparing an output value from a concentration sensor with either of the levels of the reference voltage and controlling toner concentration. CONSTITUTION:The plural levels of the reference voltage are selected according to the signal level of the output ports P1 and P2 of a microprocessor 1 and compared with the output value from the toner concentration sensor 5 of a developing device 6 by the comparator 2. When the toner concentration is higher than that at the level of the reference voltage, the level on a side where the density is one rank higher is set as the level of the reference voltage. Immediately after applying power supply voltage, the output from the sensor 5 is compared with the reference voltage on a side where the density is low to control the toner concentration, and the level of the reference voltage is changed to the side where the density is high to be in a stable state as the temperature of the toner rises. Thus, the blank part of the paper already printed is prevented from being contaminated at the switching point of the reference voltage of the comparator or at the time of applying the power again after turning off a power source and the printing density is prevented from lowering.
