Title: Vibration proofing structure for optical mirror for image forming device
Inventor: AKURA KAZUYA
IPC: G03G15/04
Filed: 1989-12-08
Abstract: PURPOSE:To prevent a mirror from being resonated with the vibration of a motor, etc., without damaging the flatness of the mirror and to prevent image blurring by interposing a vibration proofing member between the optical mirror and its supporting frame through a sandwiching means. CONSTITUTION:As to 1st and 2nd mirrors 3 and 4, the vibration proofing members 6 and 7, 11 and 12 are respectively interposed between the sandwiching members 5 and 10 and the supporting surfaces 91 and 92 of the supporting frame 9, so that its rigidity is increased and the peculiar vibration numbers of the mirrors 3 and 4 are deviated to a higher band side. That means, in the case that the vibration proofing member is disposed, the resonance does not occur in the mirror even though the mirror is resonated with the vibration of the motor, etc. The vibration proofing members 7 and 12 can be disposed on two positions on both end sides of the supporting frame 9 in a longitudinal direction, and also can be disposed so as to uniformly fill a space between the supporting surfaces 91 and 92. And it is desirable that the fixing positions 8 and 13 of the members 5 and 10 are positioned on the central part in the longitudinal direction of the mirrors 3 and 4, but the other part can be good.

Title: Solid-state image sensing element
Inventor: TORIYAMA KEIJI
IPC: H04N5/335
Filed: 1988-12-19
Abstract: PURPOSE:To remove the through of channel potential which is caused by a solid-state image sensing element at overlap between a photoelectric conversion element and a read electrode and then improve the defect that appears in residual image by causing an insulating film below the read electrode to have a film thicker than a part on a read channel region located on the photoelectric conversion element. CONSTITUTION:A silicon oxide film 7 on an N<-> type region 3 has a film exceedingly thicker than that of any other region. When read pulse voltage is impressed to read electrodes, the thicker the oxide film becomes, the smaller a voltage effect of channel potential becomes. As the trough of potential is removed by causing potential on the N<-> type region 3 of a photodiode to be lower than read channel potential 6, a signal charge (e) is read after transferring it to a CCD shift register N-type region 4 without being left very much. In this way, there is no possibility of destroying signal conversion characteristics almost without lowering light conversion efficiency.
