Filed: 1997-12-24
Abstract: PROBLEM TO BE SOLVED: To remove an unnecessary photoreceptive layer formed on one end face at the time of applying a photoreceptive layer on an electrically conductive supporting body by immersion regardless of the diameter of a photoreceptor to be produced. SOLUTION: This device is provided with a cleaning member 5 consisting of a holding body 5a where a removing brush 5b is flocked, and by immersing in solvent in a solvent tank the brush 5b of the member 5 is brought into contact with the end face of the photoreceptor 64 where the photoreceptive layer applied by an immersion coating method is formed on the surface of an electrically conductive base substance. By rotating the photoreceptor 64, the applied unnecessary photoreceptive layer is removed by its contact part with the brush 5b.  In such a case, the member 5 has circular-arc shape whose diameter is much larger than the outer peripheral diameter of the photoreceptor 64, so that a part of the brush 5b is brought into contact with the photoreceptor 64 and a part of the brush 5b is not brought into contact therewith even when the diameter of the photoreceptor 64 is different, whereby the adhering degree of the residue of the removed photoreceptive layer to the brush 5b is reduced, but removing processing is efficiently performed.

Title: High frequency switch
Inventor: KODO GIICHI
IPC: H04B1/44
Filed: 1992-12-22
Abstract: PURPOSE:To obtain the inexpensive high frequency switch with a small insertion loss. CONSTITUTION:A transmission circuit TX is connected to an antenna ANT via a 1st diode 14. Furthermore, the antenna ANT is connected to a reception circuit RX by using a circuit including a strip line 28 and a 2nd diode 32. Two diodes 14, 32 are conductive by impressing a positive voltage to a 1st control terminal 22. The signal from the transmission circuit TX is sent from the antenna ANT in this state. The transmission signal is not sent to a reception circuit RX because a strip line 28 is connected to ground by the 2nd diode 32 resulting in being resonated. A positive voltage is applied to a 2nd control terminal 40 at reception. The voltage is divided by resistors 26, 36 and the divided voltage is impressed to the diodes 14, 32 as a reverse bias voltage to surely turn off the diodes.
