Patent JP-H05259521-A (JP)
Title: Dc-driven josephson output buffer circuit
IPC: H01L39/22
Filed: 1992-03-13
Abstract: PURPOSE:To enable transmission of a signal of small waveform distortion by connecting a resistance between an output terminal and a transmission line. CONSTITUTION:When an output voltage is finite, an output impedance is equal to the combined resistance Rs of a load resistance R1 104 and a parallel resistance Rp 105. When an output voltage is zero, an output impedance becomes zero. Therefore, time average of an output impedance can be estimated to be Rs/2. Since the load resistance R1 and the parallel resistance value Rp are merely 10OMEGA, Rs/2 is also 10OMEGA and is enough small as compared with a value of a characteristic impedance of a transmission line 116 which is usually 50OMEGA. Therefore, if a resistance 105 of a value obtained by subtracting merely 10OMEGA from a value of a characteristic impedance of the transmission line 116 is connected between an output terminal 111 and the transmission line 116, the output impedance of an output buffer circuit viewed from the transmission line 116 is effectively equal to a characteristic impedance of the transmission line 116, and thereby transmission of a signal of a small waveform distortion having good impedance matching is enabled.

Title: Electrophotographic recording device
Inventor: KIKUCHI KO
IPC: G03G21/10
Filed: 1990-03-08
Abstract: PURPOSE:To adjust a cleaning member which is deformed before cleaning ability becomes equal to or under specified one by comparing the set value of the number of printed sheets corresponding to the deformation amount of the cleaning member with the value of the number of printed sheets and driving and rotating a heating roller in a normal or reverse rotation direction. CONSTITUTION:A comparison means 16 compares the value of the number of printed sheets after incrementing by one by a printed sheets counting means 14 with the content of a printed sheets number set value storing means 15 and outputs the compared result to the means 14 and a driving control means 17. When the compared result shows that they are not equal, the means 17 controls to drive and rotate the heating roller in the normal rotation direction, and when they are equal, it controls to drive and rotate the heating roller in the reverse rotation direction before a printing action. Therefore, when the value of the number of printed sheets attains the set value of the number of printed sheets corresponding to the deformation amount of the felt surface of a fuser pat, the heating roller is reversly rotated so as to adjust the deformation of the felt surface. The deformation of the felt surface is adjusted before the cleaning ability becomes equal to or under the specified one.

Title: Flash fixing device
Inventor: TAKAHASHI TOYOHIKO
IPC: G03G15/20
Filed: 1979-05-06
Abstract: PURPOSE:To lower the temperature rise in reflecting plates and make the exchanging of a flash discharge tube easy by disposing the opening of the conductor secured to the flash discharge tube in opposition to recording paper and forming an opening to the conductor back side of the reflecting plates enclosing the flash discharge tube. CONSTITUTION:The flash discharge tube is constituted by closely contacting a plate body 5 having high light reflecting characteristic and electric conductivity to the outside surface of a tube bulb 1 and the opening 5a for light transmission of the plate body 5 is opposed to recording paper PR. The reflecting plates are constituted by two sheets 81, 82 and an opening is formed at their top end. The surrounding air passes in the clearance at the bottom ends of the reflecting plates 81, 82 and the top surface of a guide plate 9 and enters between the reflecting plates 81, 82, where it ascends and escapes through the opening. By the convection of this air, the temperature rise between the reflecting plates 81, 82 is suppressed. In addition, the flash discharge tube 1 is prevented from leakage of radiations by the metal plate 5, thus the radiations may be concentrated to the recording paper PR by making a radiation range narrower. In this way, the temperature rise in the reflecting plates may be made lower and the exchanging of the flash discharge tube made easier.

Title: Combustion chamber for cylinder fuel injection type internal combustion engine
Inventor: NAKAGAWA YASUHIKO
IPC: F02B23/10
Filed: 1980-04-25
Abstract: PURPOSE: To increase a volume or fuel rate of gas caused by a compression stroke of the internal  combustion engine and impove a fuel consumption by a method wherein a communication port between a spherical piston combustion chamber in the piston and a main combustion chamber is arranged substantially in a tangential direction of the inner wall surface of the piston combustion  chamber.  
     CONSTITUTION: When the piston 1 is filled up, the air in the main combustion chamber 11 is  pushed into the spherical piston combustion chamber 10. During the operation, the communication port 12 is reduced to show a small sectional area and inclined in a tangential direction with respect to the inner wall surface of the piston combustion chamber 10. And due to the fact that the  piston combustion chamber 10 shows a spherical or substantial spherical shape, a sufficient eddy  flow caused by a squish may be provided and may hardly be reduced. When the fuel is injected  from the injection valve 3 through the communication port 12, the fuel may be ignited under its  compressed condition, made to form some fine particles under an action of eddy flow caused by  the squish, make a rapid expansion of the flame plane and then provide a transmission of flame  toward the main combustion chamber 11. Less heat loss is found in the piston 1 with being different from that of the cylinder head 7, then a fuel consumption may be improved.

Title: Hydraulic control valve
Inventor: KUBOTA HITOSHI
IPC: B60T8/26
Filed: 1979-05-07
Abstract: PURPOSE: To avoid the danger of producing the rear wheel locking dut to an excessive hydraulic pressure of the rear wheel brake by shutting the hydraulic pressure at midway beteeen an liquid inlet ports and liquid outlet port by the self-closing of the normally closed valve immediately after the G ball starts to move in the hydraulic control valve used for the brake of the automobile.  
     CONSTITUTION: The master cylinder hydraulic pressure generated with the depressing of the brake pedal is fed intact to the rear wheel from the port 4 via the ball chamber 2 and the port 5. As the deceleration of the vehicle exceeds a certain value during the braking under the pressure, the ball G moves leftward against the gravity working along the inclination of the tray 11. With such an arrangement, the valve body 9 is tilted and released with the spring 8 so that the valve 6 is closed by itself to shut the port 4. In this manner, further rise is checked in the hydraulic pressure to the rear wheel cylinder from the port 4 thereby preventing any rear wheel locking.
