Patent JP-H04204964-A (JP)
Title: Developing device
Inventor: FUJII JIRO
IPC: G03G15/08
Filed: 1990-11-30
Abstract: PURPOSE:To prevent developer from being excessively supplied to parallel developing drum by making a gap between a photo-sensitive body and a reversing developing drum larger than a gap between the photosensitive body and the parallel developing drum and making the surface of the parallel developing drum rougher than the surface of the reversing developing drum. CONSTITUTION:Developer which circulates along an arrow in a developing device 11 forms a magnetic brush on the surfaces of the parallel developing roller 23 and the reversing developing roller 22 so as to develop an electrostatic latent image on the photosensitive drum 9. Since the gap S1 between the roller 22 and the drum 9 is made larger than the gap S2 between the roller 23 and the drum 9, the developer on the roller 22 side is not supplied to the roller 23 side but carried to a peeling roller 31 side with the rotation of the roller 22. Then, the surface of the roller 22 is formed to be dense, so that napping becomes weak and the reproducibility of a thin line is improved, and the surface of the roller 23 is formed to be rough, so that napping becomes tough and image density is made high.

Filed: 1994-12-28
Abstract: PURPOSE: To prevent a malfunction of a power window by providing a circuit which prohibits an automatic reverse operation, when a car is in a predetermined state, in a control device of power window which detects the penetration of an object during a closing operation to effect a reverse operation. CONSTITUTION: When a power window is in a closed state by means of an open/closure switch 11, drive current (ripple pulse) to a motor 5 is detected (14) and if, at least, either of amplitude or frequency becomes larger in comparison with amplitude or frequency under normal load, it is judged that a penetration of an object has occurred and the motor 5 is automatically put into a reverse operation. Sensing devices S1-S5 for sensing the conditions of car such as open/closure of door, running state of car (position of speed change gear), drive voltage drop, operation condition of motor are provided in a control circuit 12, and when these conditions are in predetermined conditions, since a driver is present near the devices, even if ripple current increases, automatic reverse operation is not effected.  And by providing an automatic reverse operation prohibiting switch, reverse operation at the time of malfunction can be prevented. Thus, the power window can be opened or closed smoothly.
