Title: Constant voltage device
Inventor: ODA KATSUHIRO
IPC: H02M5/257
Filed: 1991-08-20
Abstract: PURPOSE:To obtain a low-cost and high-quality stabilized power source by connecting resisters to both the lines of AC power, respectively, and providing a voltage detection part at the other end of the respective resisters. CONSTITUTION:AC voltage is detected by a voltage detection part 16 via resisters 14 and 15. Normally the AC voltage is rectified by means of full-wave rectification and the resistor or a capacitor, etc., is connected to the output terminal of the line to construct the voltage detection part. To facilitate the design of the circuit, the resistors 14 and 15 have a same resistance value. The full-wave rectifier within the voltage detection part 16 has low withstand voltage because the operation voltage within the voltage detection part 16 is low and the voltage exceeding it is not applied. The same is true of the case where an absolute value circuit is used without using the full-wave rectifier. A signal is transmitted to a control part 17 by the voltage detection part 16 corresponding to the detection voltage. The control part 17 controls the continuity of a switching element 13 so that the voltage of a load 12 can be kept constant based on the signal.

Abstract: PURPOSE:To form a high quality picture stably by measuring the potential of the surface of a photosensitive body after or before it is turned and controlling the surface potential so as to be appropriate. CONSTITUTION:Before a series of copying process is performed, a dark attenuation amount is measured.
