Title: High sensitivity image pickup device
Inventor: KAWAMURA TATSURO
IPC: H04N5/30
Filed: 1991-08-26
Abstract: PURPOSE:To raise the rate of signal doubling to reduce dark current flow so as to provide a high sensitivity image pickup device having high image quality by removing a fluorescent screen, and stacking on a solid image pickup element charge-doubling layers having both end faces covered by holes or by electron stopping layers. CONSTITUTION:An image of a subject to be photographed is formed on a photoelectric surface 2 and photoelectrons are released from the photoelectric surface 2 according to the bright and dark parts of this input image. The photoelectron flow is focused on a conductive film 5 from an electron lens system comprising an electrode 3 in an image intensifier II tube 12 and is accelerated by an AC high voltage applied to a film 5 and the photoelectric surface 2. Then the flow is allowed to pass through the film 5 and a charge implant-stopping layer 6 and incident on a charge doubling layer 7. Signal charge doubled by the layer 7 operates as an image pickup device guided to a solid image pickup element 9 via a stopping layer 8. The image pickup device shows high sensitivity and dark currents are decreased by the stopping action of the device whereby excellent picture quality can be obtained.

Filed: 1985-09-27
Abstract: PURPOSE:To suppress a through-current by providing an N type transistor (TR) whose gate and drain are connected between P type the 1st TR and N type the 2nd TR. CONSTITUTION:When the gate input signals of TRs QP1, QN1 changes from an H level to an L level, the potential of a gate S2 is a potential lower by the threshold value of the TR QN1 than the potential of the gate S1. When the signal S changes from an L level to an H level, the potential change of the gate S2 is faster than that of the gate S1, and since the timing when the TR QN2 is turned on by the gate S2 is faster than the timing when the TR QP2 is turned on by the gate S1, the time of simultaneous-on is reduced.

Title: Cam driving device
Inventor: NAGATA JIRO
IPC: F16D11/00
Filed: 1993-08-31
Abstract: PURPOSE:To rotate a cam in first and second positions with simple constitution by constituting in such a way that when a driving gear is rotated in the forward direction, a cam shaft is rotated in the forward direction, and when the cam reaches the first position, the cam is stopped, and when the driving gear is rotated in the inverse direction, and when the cam reaches the second position, the cam is stopped. CONSTITUTION:When a retransfer motor 45 is rotated forward, a retransfer roller 36 moves automatically up to a position, that is, a first position coming into contact with an intermediate transfer drum 28. When retransfer is finished, rotation of a second gear 50 is not transmitted to a first hub 76, and is transmitted only to a second hub 77, and a second sleeve 73 is stopped after the second hub 77 is rotated until a projecting part 73b of the second sleeve 73 butts a second detent 75. Thereby, a cam 42 is stopped in a corresponding position. Since the cam 42 can be rotated in the first position and a second position without releasing contact between a clutch means and a stopper every time, a solenoid can be dispensed with, and so that constitution is simplified and cost is reduced.
