Patent JP-H01265613-A (JP)
Title: Switching circuit
Inventor: SUZUKI ATSUHIKO
IPC: H03K17/60
Filed: 1988-04-18
Abstract: PURPOSE:To prevent saturation of a switching circuit by giving a control signal to a base of a transistor(TR) with resistance division and supplying the control signal to a collector via a diode at the conduction of the collector-emitter. CONSTITUTION:While a voltage of a high level is given to an input terminal A, a voltage VC at a point C behind a resistor R1 has a sum of a base-emitter voltage VE of a TR Q and a voltage V2 across a resistor R2. Since a forward voltage VD of a silicon diode D is not different from the voltage VE, a voltage VB at an output terminal B is nearly equal to the voltage V2. When the voltage VB reaches the voltage V2 or below, a current flows to the diode D to decrease the voltage VC at the point C, the base current supplied to the TR Q is decreased to prevent the saturation of the TR Q. A TR and a diode of a high dielectric strength voltage are acquired inexpensively and a switching circuit suitable for a load or a communication transmission line is obtained inexpensively.

IPC: G03G15/08
Filed: 1980-07-14
Abstract: PURPOSE:To detect toner density always stably and accurately by adhering a developer consisting of two components to a detection part charged to a prescribed voltage and measuring the quantity of inductive electric charge at the time. CONSTITUTION:When the mixing ratio of magnetic carriers in a developer consisting of two conponents is increased, the quantity of electric charge per weight g/m is also increased.
