Title: Method for exchanging photosensitive body and electrophotographic copying device
Inventor: WAKAGI MASATOSHI
IPC: G03G15/00
Filed: 1989-09-20
Abstract: PURPOSE:To designate the exchange of a photosensitive body by measuring a residual potential so that the life of the photosensitive body may be detected and lighting an abnormality lamp when the potential gets equal to or below a reference potential. CONSTITUTION:The surface potential detected by a detector 8 is compared with the reference potential 10 by using a comparison amplifier so as to control a display lamp system 11. When the residual potential of the photosensitive body gets equal to or below the reference one, a signal showing the exchange of the photosensitive body is lighted. By exchanging the photosensitive body in accordance with the signal, a distinct image is always obtained. The photosensitive body used in this invention is obtained by forming an organic surface protective layer 16 on a photosensitive layer in which a-Si is a base. Since the exchange signal is lighted when the residual potential becomes smaller than the reference one, the photosensitive body is exchanged before the organic protective film is abraded to disappear.

Title: Solid-state image pickup device
Inventor: KATOU NAOKI
IPC: H04N5/3728
Filed: 1997-09-08
Abstract: PROBLEM TO BE SOLVED: To prevent deterioration in image quality at receiving a large signal or at transfer by giving a pulse signal used to discharge electric charges to a charge extraction means in a prescribed timing and giving an inverted pulse signal to an output gate section in a same timing as the pulse signal. SOLUTION: A timing generating section 4 outputs 4-phase vertical transfer signals Vϕ1-Vϕ4 given to a vertical transfer register 2, horizontal transfer signals Hϕ1, Hϕ2 given to a horizontal transfer register 3, and a reset gate clock RGϕ given to a reset gate RG and also outputs an inverted pulse signal in the same timing as the reset gate clock RGϕ as an output gate clock HOGϕ. Thus, in the case of transferring charges to a part corresponding to the Hϕ1 of the final stage from the part corresponding to the Hϕ2, the amount of the charge processed at the final stage of the Hϕ1 is increased and high image quality is maintained even at the reception of a large signal without decreasing the transfer efficiency.
