Title: Polychromatic recording method
Inventor: SATOU KAZUHIKO
IPC: G03G15/01
Filed: 1984-07-06
Abstract: PURPOSE:To record a polychromatic image with high resolution at a high speed by forming and developing latent images corresponding to respective colors on a photosensitive drum as a latent image formation medium repeatedly during one rotation of the photosensitive drum, and transferring toner images of many colors to a recording form by a transfer means at a time during the rotation. CONSTITUTION:The photosensitive drum 1 as the latent image formation medium has a photosensitive layer on its surface and rotate at a constant speed as shown by an arrow, and electrifier 21-23 supply uniformly a charge on the surface of the photosensitive layer. Exposure parts 31-33 form a latent image and irradiate the photosensitive layer on the photosensitive drum 1 with laser light corresponding to information such as characters to be recorded. One dot of laser light from those exposure parts 31-33 forms one picture element of information such as characters. Development parts 41-43 form the toner image of the latent image on the photosensitive layer by reversal development and one set of an electrifier exposure part, and development part forms a toner image of some color on the photosensitive layer. A transfer part 5 transfers the toner image formed on the photosensitive layer to the recording form 9 and is equipped wth a transfer corotron 51.

Title: Switching power supply and its control method
Inventor: MORIYA MASAAKI
IPC: H02M3/28
Filed: 1997-05-16
Abstract: PROBLEM TO BE SOLVED: To provide a switching power supply and a switching control method wherein, if load fluctuation occurs on the secondary side of a transformer, abrupt increase in supply voltage Vout can be prevented and the supply voltage Vout can be swiftly returned to steady state. SOLUTION: If the value for voltage Vout exceeds a voltage of Vref2 (R2+R1)/R2, the ordinary negative-feedback control mode is restarted, and the pulse width is reduced from the next PWM signal to be outputted with the voltage Vout gently inclined. If a counter counts up without the value for voltage Vout exceeding the voltage value of Vref2 (R2+R1)/R2, the ordinary negative-feedback control mode is restarted as well, and the pulse width is increased from the next PWM signal to be outputted. Thus, the value for supply voltage Vout is controlled so that it exceeds Vref2 (R2+R1)/R2 before the inclination of the supply voltage Vout becomes steep, and pulse width reduction mode is initiated.

Title: Backing prevention device for automatic transmission
Inventor: YAMAZAKI TSUTOMU
IPC: F16H61/02
Filed: 1996-05-13
Abstract: PROBLEM TO BE SOLVED: To reduce fuel consumption during an idling operation by variably controlling tightening pressure applied to a tightening element for the prevention of the hacking of a vehicle due to signals from a proceeding automatic speed change range detection means, a travel speed sensor and a throttle sensor. SOLUTION: An idling state is detected with a throttle sensor 21, an acoustic velocity sensor 2 and a range sensor 23, and the gradient of a vehicle position is detected with a gradient sensor 24. A signal from each sensor is transmitted to a control device 6, thereby finding line pressure required for preventing a vehicle from moving backward on a current gradient. Also, a signal for generating the line pressure is sent to a line pressure solenoid 7 for adjusting line pressure, and hydraulic pressure is fed to each tightening element via a speed change hydraulic pressure circuit 8. This control process generates minimum required hydraulic pressure for preventing the backward travel of the vehicle on the climbing road.  Also, hydraulic pressure remarkably lower than the case of the climbing road is generated on the flat road, thereby preventing the deterioration of fuel consumption during an idling operation.

Title: Metal bulge molding
Inventor: SATOU TAKAYUKI
IPC: B21D22/20
Filed: 1977-11-25
Abstract: PURPOSE: The press molding is operated by a thermal expansion process wherein a mold is placed on an extended material to be molded. The process provides the molded material with a suffieiently extended hight of molding without causing breakage thereof.  
     CONSTITUTION: When a metal 15 and a wire net 13 are heated, the metal 15 expands and pushes a spherical head punch 16 upward. The punch 16 causes the wire net 13 to expand and form into shape between metal molds 11 and 12. Since the molding operation is a thermal expansion process, the molding pressure exerting  on the wire net depends on the temperature. At low temperature, the wire is less  extensible and the pressure is weak, at high lewperature, the wire is more extensible and the pressure is high. Thus, the exerting molding pressure is adequately  adjusted to the net extensibility thereby providing sufficient elevation without causing wire net brekage.

Title: Angular-velocity sensor
Inventor: TAKEUCHI SACHIOSA
IPC: G01C19/5642
Filed: 1994-06-23
Abstract: PURPOSE:To provide an angular-velocity sensor whose structure can be made simple by a method wherein a piezoelectric element for drive and a piezoelectric element for detection are formed on the same face. CONSTITUTION:One to a plurality of piezoelectric elements 3 for drive and one to a plurality of piezoelectric elements 4a, 4b for detection are arranged and installed on the support main face 20 of a diaphragm 2 having the support main face 20 which is nearly parallel to the axial center of a rotation. When an electric field is applied to the piezoelectric elements 3 for drive, the' piezoelectric elements 3 for drive are expanded and contracted in a direction which is parallel to the support main face 20, i.e., in the z-axis direction. As a result, the diaphragm 2 is bent in the y-axis direction. When an angular acceleration acts on the diaphragm 2, Coriolis' force in a direction which is perpendicular to the bend direction is applied to the diaphragm 2, and the piezoelectric elements 4a, 4b which are arranged and installed on the diaphragm 2 generate a signal voltage according to Coriolis' force.

Title: Pump
Inventor: WASHIDA AKIRA
IPC: F01C21/08
Filed: 1981-09-09
Abstract: PURPOSE:To improve slidability, increase wear resistance, decrease vibration and noise, and reduce the price by manufacturing the outer periphery of a roller using a material whose major component is fluoride resin while the inside is made or rubber. CONSTITUTION:An outer periphery 8 of a roller 7 is made of a material whose major component is ethylene tetra fluoride resin, while the inside 9 of the roller 7 is made of suitable rubber. With this contrivance, the outer periphery 8 of the roller 7 is brought in elastic contact with the inside surface of a casing 1, and a fluid lubricating film is formed surely. Since the material, whose main component is fluoride resin, has less frictional resistance and high wear resistance, the slidability of the roller 7 is improved while its wear resistance is increased. Owing to the elasticity of rubber in addition to the flexibility of fluoride resin, the roller 7 can absorb vibration so that the vibration and noise can be reduced. Since fluoride resin of high cost is used only for the outer periphery 8 and the inside 9 is made of rubber of cheap cost, the whole can be manufactured at a low cost.

Abstract: PURPOSE:To obtain a carbon/carbon composite material having high smoothness and excellent heat-resistance, corrosion resistance, oxidation resistance, strength and rigidity, by depositing an SiC film on a surface of a carbon/carbon composite material and impregnating SiO2 into fine cracks formed on the SiC film. CONSTITUTION:An SiC film is deposited on a surface of a carbon/carbon composite material (C/C material) by evaporation and SiO2 is impregnated into fine cracks generated on the surface of the deposition film during the cooling process. SiO2 can be left in the fine cracks by impregnating e.g. tetraethyl orthosilicate into the fine cracks and heat-treating the silicate. The surface- treated C/C material produced by the above process enables the improvement in the dimensional accuracy of e.g. a nose cap of a reusable wing-type space shuttle which is to be exposed to the most severe history.
