Title: Cleaning device for wet type copying machine
Inventor: KUROTORI TSUNEO
IPC: G03G21/00
Filed: 1985-12-20
Abstract: PURPOSE:To extent the replacement cycle of a toner recovery container while maintaining excellent cleaning performance by performing toner recovering operation when detecting the toner concentration in a tank exceeding a specific value. CONSTITUTION:A toner concentration detecting means 110 detects the toner concentration in cleaning liquid 101. Then the toner concentration is larger than a specific value, a bias voltage is applied to an electrode roller 105 to electrodeposit toner in the cleaning liquid on the roller and the toner is scraped by a blade 116 and discharged to the recovery container 107. Only when the toner concentration of the cleaning liquid 101 exceeds the specific value, toner is electrodeposited on the electrode roller 105, so only concentrated toner is recovered efficiently in the recovery container 107 and such trouble that much cleaning liquid itself is recovered is eliminated. Consequently, it takes a long time to fill one toner recovery container 107 and the replacement cycle of the toner recovery container is made long accordingly.

Title: Optical triangular wave communication system
Inventor: ITO TAKUYA
IPC: H04B10/00
Filed: 1989-11-02
Abstract: PURPOSE:To reduce the influence of a reflected wave in a transmission line to attain bidirectional transmission by using the optical signal of a triangular waveform. CONSTITUTION:The electric signal of a doglegged wave pulse is converted into the electric signal of a triangular wave in a triangular wave conversion part 1A (1B), is converted into the optical signal of the triangular wave in an electricity-light conversion part (E-O)2A (2B) and is outputted to the optical transmission line 5.
