Title: Electrophotographic device
Inventor: AOKI FUMITAKA
IPC: G03G15/00
Filed: 1988-12-22
Abstract: PURPOSE:To prevent development in a non-picture area and to reduce the useless consumption of developer by controlling a developing bias voltage in the non- picture area to a voltage value corresponding to the residual potential of a photosensitive body. CONSTITUTION:The developing bias voltage controller 20 of an electrophotographic copying machine is mainly composed of a surface potential sensor 3, a measuring circuit 4, a control circuit 5 and a developing bias power source 6. The control circuit 5 converts a singla into a control signal corresponding to the measuring electric signal, and according to this signal, the developing bias power source 6 applies a developing bias voltage corresponding to the surface potential of the photosensitive drum 1. By such a control means a useless developer is prevented from sticking to the photosensitive drum 1. Consequently, even if the residual potential rises, it is impressed with an appropriate developing bias voltage. Moreover, developing in the non-picture area is prevented, and the useless consumption of developer is suppressed.

Title: Load control system for nonutility generator operated in parallel with utility power system
Inventor: MIYAGI DAISAKU
IPC: H02J3/00
Filed: 1997-11-12
Abstract: PROBLEM TO BE SOLVED: To prevent reverse flow of electric power to a utility power system from a nonutility generator, by controlling start/stop and loading/non-loading operation of the nonutility generator based on a reference value calculated by adding minimum output of the nonutility generator to the minimum remaining value of the utility power. SOLUTION: In stopping a nonutility generator 4, whether or not present remaining power WZ is larger than a reference value (a+c) which is obtained by adding minimum output value (a) of the generator 4 to minimum remaining power (c) from a utility power system 1 is discriminated. When the remaining power W2 is larger than the reference value (a+c), the generator 4 is started by outputting a generator starting output signal 12-1 from an automatic load controller 12 and shifted to a non-loading operation control process. When the remaining power W2 is smaller than the reference value (a+c), on the other hand, the discrimination is repeatedly performed while the generator 4 is stopped.  Therefore, no swinging is given to the power system 1, because the reverse flow of electric power to the power system 1 from the generator 4 can be prevented and the automatic release of the generator 4 from the utility system 1 can be prevented.
