Title: Wick
Inventor: HIRATA YASUSHI
IPC: F23D3/08
Filed: 1982-07-14
Abstract: PURPOSE:To control the generation and accumulation of tar substance, thereby stabilize combustion for a prolonged period of time by a method wherein at least a part of a porous fuel vaporization section formed by adding a small amount of a bonding agent to a ceramic fiber material is impregnated and adsorbed with a platinum group catalyst. CONSTITUTION:A main wick 1 is formed by adding bonding agent such as polyacrylic acid ester to silica alumina type ceramic fiber material and an auxiliary wick 2 is formed of a knitted cloth mainly consisting of glass fibers. Further, fuel vaporization section 5 is adsorbed with a platinum black catalyst as the platinum group catalyst formed by reducing hexachloro platinum (IV) acid. Due to the fact that the platinum black catalyst displays its catalytic action sufficiently by being adsorbed by the surface of silica slumina and that the temperature of the fuel vaporization section 5 is suitable for the platinum black catalyst to covert a high boiling point component or a deteriorated component into a vaporizable substance by decomposition, it is possible to reduce the generation and accumulation of tar substance.

IPC: H05K9/00
Filed: 1996-05-17
Abstract: PROBLEM TO BE SOLVED: To provide an electromagnetic wave shielding gasket having excellent contact property with a conductive member. SOLUTION: An electromagnetic wave shielding gasket 20 is provided with a core material 22 made of silicone rubber formed in a quadrangular prism sectional shape, a damping layer 24 formed to cover the surface of the core material 22 and a shielding layer 26 provided around the damping layer 24. The damping layer 24 made of a soft and fluid silicone base damping material is transformable into various shapes corresponding to the surface shapes of the contacted members, so that the contact area between the shielding layer 26 and the contacted members may be increased, resulting in lessening the contact resistance between the elements for assuring the excellent shielding property.  Besides, the damping material forming the damping layer 24 converts the applied oscillation to heat and discharges for damping the oscillation so that, even if a conductive member is applied with continuous oscillation, the fluctuation in the contact resistance between the shielding layer 26 and the contacted member may be lowered, thereby enabling the stable electromagnetic shielding performance.

Title: Slip preventing device for vehicle
Inventor: TSUDA HIROSHI
IPC: B60B39/04
Filed: 1995-05-23
Abstract: PURPOSE: To enhance air-tightness and water-tightness by scattering slip preventing particles, which, when a rotor is rotated, are supplied from a particle tank to a recessed part of the rotor via a particle-introducing opening part and a particle-discharging opening part of a pad. CONSTITUTION: Owing to the self-weight, particles in a particle tank are always in such a state as came into a recessed part 4a of a rotor via a particle- introducing opening part 3a and a particle-discharging opening part 3c of a pad 3. Accordingly, when a driver turns a switch on, an electric current flows in a harness to start a motor. The motor, rotates a shaft, thereby turning the rotor 4 via a reduction gear. Rotation of the rotor 4 removes surplus particles from a mating surface between the rotor 4 and the pad 3. Therefore, only the particles, which got into the recessed part 4a of the rotor 4 are scattered from a particle discharging part. Since all the particles except those which got into the recessed part 4a of the rotor 4 are removed by the pad 3 made of an elastic body, a fixed quantity of particles can be scattered without leakage of the particle.

Title: Color liquid crystal display device
Inventor: TAKAMATSU TOSHIAKI
IPC: G02F1/133
Filed: 1988-05-19
Abstract: PURPOSE:To improve color reproducibility of a color liquid crystal display device and to fasten switching of display color by regulating an angle of twist to 180 deg.C in laminated first and second nematic liquid crystal layer, and arranging each tilt direction on confronting two base plates to opposite direction to each other. CONSTITUTION:Light is absorbed selectively to a color polarizer 9GB or 9R, by impressing/nonimpressing an electric voltage to a liquid crystal layer 12 of a first liquid crystal display element 21. Also, a color polarizer 9G or 9RB is made selectively light absorptive by impressing/nonimpressing an electric voltage to a liquid crystal layer 18 of a second liquid crystal display element 22. Thus, the color of transmitted light can be changed to, for example, black, red, green, or blue. Moreover, the color of transmitted light through an element 21 and an element 22 can be selected securely even if plural display picture elements are driven by time division mode. Further, since each direction of tilt of liquid crystal molecules in each liquid crystal layer 12, 18 is arranged to opposite direction to each other, the time required for liquid crystal molecules to restore nonimpressed state since impressed state is shortened to several m.sec.

Title: Motor control circuit of self-processing type camera
Inventor: HOSONO TSUTOMU
IPC: G03B17/50
Filed: 1977-10-14
Abstract: PURPOSE: To achieve the stabilization of pressure-processing of film units by providing a switching circuit which turns ON an electric motor when the supply current of the motor is above a reference value and turns OFF the motor when it is below the reference value.  
     CONSTITUTION: When the end of a film unit is fed between pressure rollers 9, 9 by the forward movement of a reciprocating member 13 upon ending of exposure, the lower cam 39 of the reciprocating member 13 oscillates a timing lever 35 in the disengagement direction, thus disengaging a stopping lever 26. The stopping lever 26 then turns OFF a switch 40. However, the supply current of the motor has become higher than a reference value because the film is under pressure-processing and therefore, the motor runs in succession. When the film unit is sent out from the pressure rollers 9, 9, the load of the  motor decreases and becomes lower than the reference value, then the motor stops. Thus, stopping of the motor on the way of the pressure processing does not occur at all and the stable pressure processing of the film unit may be performed
