Filed: 2000-02-29
Abstract: PROBLEM TO BE SOLVED: To provide a developing device capable of obtaining a stable image over a long term by preventing the welding of toner to the surface of a developing sleeve even when the toner remains on the surface of the developing sleeve from which two-component developer is peeled by repulsive magnetic field. SOLUTION: A magnet 3 in the developing sleeve 21 has repulsive magnetic poles N3 and N2, and the developer is drawn up to the sleeve by the magnetic pole N2, and the developer returned from a developing part is peeled from the sleeve by the repulsive magnetic field of the magnetic poles N3 and N2. The toner happens to remain on the sleeve in such peeling. In such a case, by providing a conductive blade 31 coming into contact with the surface of the sleeve 21 between the magnetic poles N3 and N2 as a charge imparting member for the toner and applying DC voltage having the same polarity as the electrification polarity of the toner to the blade 31, the remaining toner is electrified to have the original polarity by charge injection.  Thus, the remaining toner is prevented from being retained at one spot on the surface of the sleeve so as to be prevented from being welded by replacing the remaining toner with toner adhering to the magnetic carrier in the midst of carrying the toner by the sleeve 21 or making it contribute to development in the developing part.

Title: Fluid pressure control device
Inventor: NAKAMURA EIJI
IPC: B60T13/68
Filed: 2000-03-17
Abstract: PROBLEM TO BE SOLVED: To provide a fluid pressure control device for controlling a brake fluid pressure with the control of a solenoid control valve, inhibiting the lowering of control accuracy of the brake fluid pressure resulting from a change in temperature. SOLUTION: A pressure intensifying linear valve 162 is opened/closed depending on whether resultant force of differential pressure operating force F1 and solenoid force F2 is greater than elastic force F3 of a spring 174 or not. In this case, a lower limit value for the solenoid force F2 is determined by a lower limit value for a current actually flowing in a coil 178 and by a lower limit pulse width of a FET 242. The current actually flowing in the coil 178 is larger if a temperature is lower and a resistance is smaller, and the generated solenoid force F2 is greater, accordingly. If the liquid pressure of a power liquid pressure source 12 is lower and the differential pressure operating force F1 is smaller when the temperature is lower, the resultant force can be controlled as required without lowering the solenoid force F2.
