Title: Paper feeder of copying machine
Inventor: MURAI KAZUO
IPC: B65H9/00
Filed: 1981-09-04
Abstract: PURPOSE:To facilitate timing of feed of various sizes of papers, by controlling paper drawing action in accordance with a paper end detection signal produced from a sensor installed more upstream from register rollers. CONSTITUTION:When a sensor 13 detects the front end of paper 2 fed from a paper feed roller 5, register rollers 14, 15 are stopped, and pulses transmitted from a pulse generator begins to count. When the count reaches a number of pulses set for paper feed in accordance with the size of the paper 2, the feed roller 5 is stopped. When a synchronizing signal is generated upon coincidence of the front end of an image formed on a photosensitive drum 17 with the front end of the paper 2, a clutch 19 is engaged, the register rollers 14, 15 begin to rotate, and the paper 2a held on stand-by starts to move. With the paper different in size, paper feed control corresponding to paper size can be likewise executed only by changing the set number of said pulses starting upon receiving the paper end detection signal of the sensor 13.

Title: Solid-state image pick up device
Inventor: KANESAKA KAZUMI
IPC: H04N5/335
Filed: 1991-06-11
Abstract: PURPOSE:To eliminate problems caused by a light shield film by interposing an optical anti-reflection layer in a second transparent dielectric film with an arrangement wherein the coating layer is overlaid on the light shield film, and by extending this optical anti-reflection coating layer over the entirety of a semiconductor substrate, except for a region designated for the formation of bonding pads. CONSTITUTION:An organic transparent protective film 35B is deposited over the surface of a semiconductor oxide film 35A in which light shield films 37 are formed. Formed in the layer of the protective film 35B is an optical anti- reflection film 38 with an arrangement wherein the anti-reflection film is overlaid on the corresponding light shield film. This optical anti-reflection film 38 is extended over the entirety of a solid-state image pick up device 3, except for a region designated for the formation of bonding pads 4. When this device undergoes a selective etching using a mask after the deposition of a resist film which serves as a color separation filter 39, light irradiated to the light shield film 37 is interrupted by the optical anti-reflection film 38, thereby reducing the light reflected by the light shield film 37 to a negligible extent.

Title: Direct coupling amplifier
Inventor: OKASHIN YAMATO
IPC: H03F3/343
Filed: 1988-06-06
Abstract: PURPOSE:To eliminate the dispersion in an output circuit by giving correlation between a base-emitter voltage of an NPN transistor(TR) and a base-emitter voltage of a PNP TR. CONSTITUTION:A correlation is given between a base-emitter voltage of an NPN TR and a base-emitter voltage of a PNP TR. That is, a voltage difference (V1-V2) between the base-emitter voltages V1, V2 of the TRs Q1, Q2 is replaced into a voltage difference (V2-V4) of the base-emitter voltages V2, V4 of the TRs Q2, Q4 of the same polarity and the voltages V1,V2 have the correlation through the voltage V4. Thus the dispersion in a DC output current I caused by the voltage difference (V1-V2) is much reduced, and the dispersion in an AC output current (i) is decreased. Since the current negative feedback quantity is reduced, the resistance R2 is decreased and the voltage drop across the resistor R2 is reduced. Then even with a low power voltage Vcc, the dispersion in the output current is suppressed.

Title: Packet switch
Inventor: OZAKI NAOHIKO
Filed: 1988-06-08
Abstract: PURPOSE:To avoid overflow of packets in an input buffer by outputting a packet from each input buffer means in a period shorter than a packet input period and giving the packet to a spatial switch. CONSTITUTION:The system is provided with plural input buffer means provided corresponding to input ports 2 and storing respectively plural input packets, plural output buffer means provided corresponding to plural output ports 4, a spatial switch means 3 interposed between the input buffer means and the output buffer means, and a packet operation control means 6 outputting a packet from each input buffer means in a period shorter than the packet input period and supplying it to the spatial switch 3. Thus, since output opportunity of two packets or over is given while one packet is inputted to the input buffer, the rate of use of each input buffer is suppressed less than 50% equivalently. Thus, saturation of the input buffers and extreme delay of packet are avoided.

Abstract: PURPOSE:To change the aspect of a water spouting consciously or artificially by arranging cylindrical guiding part members to the circumference of spouting nozzles and providing a squeezing mechanism by adjusting the cross sectional area of the passage of water stream on the circumference of guiding part members. CONSTITUTION:The guiding part member 3 is arranged with stationary condition to the circumference of the outlet of the spouting 2 of the nozzle 1. The pressurized water is designed to sent it into the nozzle 1 by the pump P. When the pressurized water is pumped from the pump P is spouted from the spouting outlet 2 of the nozzle 1, water from surrounded section by the guiding part member 3 and lower section of the guiding part member 3 are incentively accompanied with the water stream from the above-mentioned outlet 2 and the water spouting 5 having the aspect of swelling to the definite height is formed. When by adjusting the angle of rocking of the movable plate 6 the cross sectional area of the water stream passage 4 is increased, the water spouting having the aspect of swelling thickly standing from the surface of water is formed, on the other hands, when the cross sectional area of the water stream passage 4 is decreased, the mode of water spouting 5 becomes swelling snugly. By this means, the aspect of the water spouting is making it possible to change consciously or artificially to various aspects.

Title: Vacuum cleaner
Inventor: KOBAYASHI SADAO
IPC: A47L5/22
Filed: 1992-05-29
Abstract: PURPOSE:To provide a case formation by means of a die which does not require any particular securance of strength even if a motor blower with increased output power is incorporated, by forming an inner case where a dust gathering chamber and a blower chamber are formed in consolidated shaping, and fixing this inner case to the inside of the body of a vacuum cleaner concerned. CONSTITUTION:A dust gathering chamber 31 and a motor blower chamber 32 are formed in consolidated shaping with an inner case 16, which is secured by screw S to an upper case 14 and a lower case 15, and thus the body 11 of a vacuum cleaner is formed. The gap between the upper and lower cases 14, 15 is sealed by a bumper 24 held pinchedly, and thereby the exhaust wind inside of the body case is not likely to leak to outside. Even though the wall thickness of the inner case 16 is enlarged to increase the strength, the inner case 16 itself remains unexposed as any appearnace portion of the cleaner body 11. This allows relieving of the shaping conditions in view of preventing generation of thermal shrinkage, weld line, etc., to ensure that the quality control is conduted easily, and thus a strong vacuum cleaner is achieved without bringing any rise of the product price.

Title: Leak inspection apparatus
Inventor: SAWATANI TERUO
IPC: G01M3/24
Filed: 1988-06-08
Abstract: PURPOSE:To obtain excellent workability and to execute accurate inspection by providing a fine pipe nozzle and an ultrasonic transmitter-receiver. CONSTITUTION:When a hollow container has a pinhole or a welding inferior place, gas is leaked therefrom and the gas in a pipe body 23 flows toward the hollow container and, therefore, the pressure in a hermetically closed container 13 is gradually lowered. By this mechanism, the gas in the pipe body 21 flows in a fine pipe nozzle 11 to be injected from the leading end of the nozzle 11. When the gas is injected from the leading end of the nozzle 11, an ultrasonic wave is generated at the leading end of the nozzle 11 by ultrasonic effect to be detected by a receiver 25 and the fact of leakage is detected on the basis of the detection signal outputted from the receiver 25. Therefore, excellent workability is obtained and accurate inspection can be performed.
