Title: Solid-state image pickup device
Inventor: TAKEMOTO KAYAO
IPC: H04N5/335
Filed: 1982-03-03
Abstract: PURPOSE:To reduce fixed noise, by quickening the potential change speed of an n<+> diffusion layer, obtaining early stabilized potential and flowing out charges under gates at the same time, in a two-dimension solid-state pickup device performing horizontal scanning with charge transfer elements (CTD). CONSTITUTION:A short gate 81, 4mum in gate length is provided between the n<+> diffusion layer 66 and a gate 68. As shown in Figure B, the threshold to the layer 66 is executed at a barrier 801 made of the gate 81, and the potential formed by the gate 68 is made sufficiently lower than the barrier. Since the barrier 801 has a shorter length, charges flow quickly, the potential change in the n<+> layer is fast, and flowing of electrons under the gate 68 is reduced quickly. Since no new current injection exists, the charges under the gate 68 flow out an n<-> layer 63 of a CTD, 23A quickly and no reading error exist. In the reset operation, and also in a CTD, 23B, the same effect is obtained entirely and fixed noise due to transfer errors is eliminated independently of the variance in MOSTs 29A and 29B.

Title: Drive for motor of endoscope
Inventor: SUZUKI AKIRA
IPC: A61B1/00
Filed: 1990-02-13
Abstract: PURPOSE:To achieve a low speed and a high a torque without increasing the size of a device by setting the motion quantity of a second traction part to be 1/2 and the tensile force twice when a motor is driven to rotate for tracting a first tracting member, and setting the moving directions of a second pulley and the second traction member to be almost similar to an insertion part. CONSTITUTION:By rotation of a motor 9, slide members 23a, 23b move along cuts 26a, 26b. The motor 9 rotates right to move the slide member 23a from a neutral position toward the motor 9, while the slide member 23b slides toward an insertion part. For this moving action, a second traction member 13a for up curvature is tracted, so a curvature part 6 is curved up. At this time, the motion quantity of the second traction member 13a is half the motion quantity of a first traction member 11a, so twice the tensile force is generated at the second traction member 13a to the tensile force of the first traction member 11a by the motor 9. By rotating the motor 9 inversely, the curvature part 6 can be curved down.

Abstract: PURPOSE:To simply and efficiently dry and fire wet gel without cracking even when the gel is made from a soln. having an arbitrary compsn. CONSTITUTION:When glass is produced by a sol-gel process, a soln. of an alcohol- or water-soluble org. polymer is substd. for a liq. present in the pores in wet gel and then the gel is dried and fired. Since the org. polymer is not added to an aq. soln. for hydrolyzing metal alkoxide, the viscosity of the soln. is not high and the water mixes rapidly with a stock soln. Hydrolysis and polycondensation uniformly take place and do not partially proceed, accordingly the resulting gel cracks hardly.

Abstract: PURPOSE:To rapidly execute a processing by a button depression discriminating means and to improve the operating and processing speed of a host computer by sampling the output signal of two operating buttons provided on a mouse at every fixed cycle and outputting it. CONSTITUTION:The output signal of an L button 1 and an R button 2 of a mouse 10 is sampled at the generating cycle of a clock pulse set by a pulse interval setting means 24 and a clock generating means 23 by an FF 21 and an FF 22, and is outputted by a button depression discriminating means 5. In this case, the time of the generating interval of the clock pulse outputted by the means 23 is set more than the time when the timing deviating time of the depressing of the buttons 1 and 2 and a chattering time to generate on depressing are added. Thus, the probability of which the output signals of the FF 21 and the FF 22 become high at the same time, and the executing time of the processing of the means 5 is shortened. Consequently, the time for the condition judging of the buttons 1 and 2 of a host computer 12 is shortened, and the original operating and processing speed of the computer 12 can be improved.

Abstract: PURPOSE: To simplify the structure of an arithemetic circuit used in an air-fuel ratio controlling system, by providing an AC coupling circuit for removing DC component from the output signal of an exhaust-gas sensor and taking out its fluctuating component, and controlling the air-fuel ratio by the result of comparison between the output of said AC coupling circuit and a reference level.  
     CONSTITUTION: When an engine is set into operation and an exhaust-gas sensor 8 is fully activated, an output signal fluctuating in a wide range of voltage is produced from the sensor 8, so that an amplified signal A shown in the latter half of wave form (a) is produced at the output terminal of an amplifier 91 in a control circuit 9. The signal A is converted into a signal B by an AC coupling capacitor 92a in a comparison circuit 92, and a comparator 92f produces an output shown by wave form (c) in the drawing by compensating the setting level in response to the signal B.  The output signal of the comparator 92f is afforded via an integration circuit 93a to  a comparator 93c in a modulating circuit 93, in which it is compared with the output of a triangular-wave generator 93b. Here, the output of the modulating circuit  93 serves to drive a vacuum control valve 10 at about 30Hz by a driving circuit 94, for effecting intermittent control of a control valve disposed in a passage by- passing a carburetor.

Title: Lamination type electrophotographic sensitive body and electrophotographic method
Inventor: KITAYAMA HIROYUKI
IPC: G03G5/047
Filed: 1984-02-24
Abstract: PURPOSE:To prevent generation of a carrier trap and to decrease generation of an optical memory and an electrification memory by specifying the dielectric constant in an electric charge transfer layer at a specific value. CONSTITUTION:The dielectric constant in the electric charge transfer layer of a lamination type photosensitive body is made <=3 and the process having electrification-exposing by using such photosensitive body is repeated at least twice or above. The dielectric constant of such charge transfer layer having >=3 dielectric constant can be decreased to <=3 by mixing a charge transfer material and resin and forming a coated film even if both of the charge transfer material and resin have >=3 dielectric constant. The possible reason thereof lies in that the polar groups of both materials are weakened by the interaction. The dielectric constant can be made to <=3 by adjusting the mixing ratio of the chrge transfer layer and the resin so as to decrease the mixing ratio of, for example, the resin. The charge transfer layer having about 2.8 dielectric constant is obtd. from, for example, a styrene resin and hydrazone compd. Generation of a carrier trap is prevented and the repetitive characteristic is improved by using such charge transfer layer having <=3 dielectric constant.
