Title: Electrifying device
Inventor: WATANABE YUKIO
IPC: G03G15/02
Filed: 1995-10-27
Abstract: PROBLEM TO BE SOLVED: To prolong the service lives of an electrifying member and a cleaning member therefor by setting cleaning timing by the cleaning member in accordance with the using environment and using circumstances of an electrifying device. SOLUTION: For example, in the case of consecutively forming an image on 500 sheets of transfer material, an electrifying roller 3 is cleaned every 50 sheets. Meanwhile, in the case of forming the image on 500 sheets of transfer material one by one by depressing a copying button 500 times, the roller 3 is cleaned when the image is formed on the 500th transfer material. Namely, in the case of forming the image on the same-number sheets of transfer material, staining is more in the case of consecutively forming the image than in the case of forming the image one by one because the time for post-rotation to reduce the staining of the roller 3 is less in the former case than in the latter case, so that cleaning frequency is increased in the former case.  By setting the cleaning of the roller 3 in accordance with the using environment and the using circumstances in such a way, the irregular electrification is prevented without spoiling the lives of the roller 3 and the member 1 themselves.

Title: Vehicular radio equipment
Inventor: IDA MASAYUKI
IPC: H04B7/08
Filed: 1995-10-30
Abstract: PROBLEM TO BE SOLVED: To prevent distortion by a suitable attenuation amount due to combination while utilizing the isolation characteristics of a transmission-reception changeover switch itself in the case of strong input. SOLUTION: When a signal is received by a 1st antenna 1, a transmission- reception changeover switch 4 is switched to the side of a reception system circuit part 8 through a filter 3 passing through a specific frequency band. A reception strength detection circuit built in this reception system circuit part 8 detects the level of reception strength. In the case of strong input for which this level is higher than a specified value, the transmission-reception changeover switch 4 is switched to a transmission system circuit part 7 by a control signal from a control part 10. In the case of reception strength for which the reception strength level is lower than the specified value, that switch is changed over to the side of the reception system circuit part 8 as it is.  Thus, since the transmission-reception changeover switch is changed over to the transmission system circuit part even during reception in the case of strong input, the suitable attenuation amount due to combination can be provided while utilizing the isolation characteristics of the transmission-reception changeover switch itself. Thus, the distortion in non-linear areas can be prevented.
