Title: Electrophotographic photoreceptor
Inventor: ICHIKAWA YOSHIHARU
IPC: G03G5/00
Filed: 1978-07-12
Abstract: PURPOSE: To prevent aging changes and deterioration of moisture resistance in recording characteristics and enhance the recording characteristics and reliability, by filling the cavity in a sintered type photoelectric conductor layer with a specific insulating material.  
     CONSTITUTION: A liquid composition containing CdS, sealing glass, etc. is spread on a conductive supporting body and dried, and is baked at 600°C in air atmosphere. This porous photosensitive layer thus sintered and formed mainly with inorganic photoconductive material is dipped and coated with a solution of insulating material such as polyvinyl chloride resin in which are dispersed insulating particles of low dielectric constant such as polytetrafluoroethylene particles. After removing excess resin on the surface, the solution is allowed to dry naturally. Thus is obtained a electrophotographic photoreceptor having almost the same dielectric constant as the electrophotographic photoreceptor before filling. Therefore, even when a high voltage necessary to obtain sufficient recording concentration is applied, state of fog on recording is almost negligible practically.

Filed: 1982-05-19
Abstract: PURPOSE:To detect the vehicular position with a relatively simple constitution, by providing a light receiving device which transmits a light reception signal when the light radiated from a prescribed known position toward different directions successively is received through the position of a rotary light reflecting material on the vehicle and taking a signal, which indicates the direction of radiation at the transmission time, and a signal indicating the rotation angle of the reflecting material from a reference direction. CONSTITUTION:When a laser light is incident to a photodetector 14 of a laser light source 1, the photodetector 14 sends the light reception signal to a transmitter 15. Then, the transmitter 15 transmits an angle alpha of the output of a rotary encoder 13 and a discrimination signal indicating the light reception of the photodetector 14. These signals are received by a receiver 35 on a vehicle V and are given to an operation controlling part 34, and an output value gamma1 of a rotary encoder 33 and the angle alpha are stored in the operation controlling part 34. When a reflecting material 31 is rotated and a light receiving device 2 is irradiated with the reflected light, the light reception signal is transmitted from the light receiving device 2 to the vehicle V through the transmitter 15. The operation controlling part 34 of the vehicle V reads an output value gamma2 of the rotary encoder 33 by this signal and uses this value and the output value gamma1 to obtain a direction gamma of the reflected light.
