Title: Method for adjusting image density for electrophotography
Inventor: TAKEUCHI AKIHIKO
IPC: G03G13/08
Filed: 1987-12-15
Abstract: PURPOSE:To execute the proper adjustment of image density by changing a bias voltage which is impressed on the substrate of an image carrier. CONSTITUTION:A grid 20 is attached in a primary electrifier 17. When primary electrification by the electrifier 17 is negative electrification, grid bias GB impressed on the grid 20 is made to be a negative voltage. A bias potential Vs is impressed on the substrate 3 of a photosensitive drum 1 by a variable bias power source 21. In case of increasing the image density, the potential Vs is shifted by the power source 21 in a direction where the difference with the potential of a dark part Vd becomes large. At such a time, the potential Vd is hardly changed in virtue of rectification effect of the grid 20 and the potential of a light part is shifted to a direction same as the power source Vs. Thus, the proper adjustment of the image density can be executed.

Filed: 1992-11-26
Abstract: PURPOSE:To accurately measure a primary impedance of an induction motor by cutting OFF a current in a state that power is supplied to the motor by a polyphase AC power source having a power cutting-off function. CONSTITUTION:Power is supplied from a three-phase AC power source 1 to a three-phase induction motor 2 via a breaker 3.

In this case, when a measurement start switch 7 is closed, a logic of a measurement start signal 8 becomes '1', and a contact of the breaker 3 is opened. Accordingly, power supply to the motor 2 is abruptly stopped. Thereafter, the switch 7 is input to the circuit 6. Then, a primary impedance of a vector sum of a primary resistance r1 and a primary reactance x1 is measured.
