Title: Refrigerator
Inventor: NAKADA JUNICHI
IPC: F25D23/06
Filed: 1995-04-04
Abstract: PURPOSE: To provide a refrigerating chamber which is not burnt or hardly burnt by a method wherein a heat insulation box body and a cooling system constituting the refrigerating chamber are made non-combustible or flame-retardant. CONSTITUTION: A heat insulation box body 27 is formed in a non-combustible or a flame retardant state and a part of a cooling system 28 is also formed in an incombustible or a flame retardant state. The heat insulation box body 27 comprises or is constituted of incombustible or flame-retardant parts and the cooling system 28 also comprises or is constituted of incombustible or flame-retardant parts. A means to bring it into an incombustible or a flame retardant state substitutes a resin part form a metal, covers a resin part with a metal, and is incombustible or flame retardant surface treatment of a resin part through resin modification. In the refrigerator, when combustion originates from a refrigerator itself, since the heat insulation box body and the cooling system are incombustible or flame retardant, combustion is insignificant.  When the refrigerator catches fire from other origin of combustion, since the heat insulation box body and the cooling system are incombustible and flame retardant, catching fire from other origin of combustion is prevent and a spreading fire is blocked.

Title: Air bag driving device
Inventor: HAYAKAWA YOSHIHIRO
IPC: B60R21/16
Filed: 1993-03-12
Abstract: PURPOSE:To provide an air bag driving device which has less risk of malfunction associate with up-and-down impacts applied to a car when it runs on a rough road. CONSTITUTION:A car such as an RV car is fitted with a fore-and-aft G sensor 10 to sense vibrational impacts in the direction fore and aft and an up-and-down G sensor 11 to sense vibrational impacts applied in the direction vertical. The obtained signals are fed to an impact judging apparatus 12. The impact judging apparatus 12 shuts the high range components of the up-and-down G signal level using a low-pass filter 14 and adjusts the output level. When the difference with the fore-and-aft G signal level exceeds the specified value, an impact signal is emitted to actuate an initiator 3. Even though the car is running on a road with large surface unevenness, air bag 3 is free from risk of undeliberate explosion.

Title: Humidity sensor
Inventor: IKEJIRI MASAHISA
IPC: G01N27/12
Filed: 1989-03-30
Abstract: PURPOSE:To obtain a resistance value variation type humidity sensor capable of precisely measuring humidity in a wide range with a simple circuit by utilizing a silica film having a crack as a moisture-sensitive film. CONSTITUTION:A film having a crack is easy in adsorption and desorption of water and can be utilized as the moisture-sensitive film of a humidity sensor. At this time, current is allowed to flow by ionic conduction due to H<+> generated by dissociation of water adsorbed to the crack. Therefore in order to obtain the humidity sensor having small resistance value, the interval of a couple of electrodes is desirably connected by the continuous crack. Further when the width of the crack is made excessively wide, water is made difficult to be adsorbed to the crack. Therefore the existence of the crack having <=10mum width is desirable. In such a way, conductivity can be freely changed by controlling formation of the crack. Therefore the linearity of change in resistance value for the change in relative humidity is made excellent. The resistance value variation type humidity sensor can be produced which is easily capable of measuring even low humidity large in resistance value. Humidity in a wide range can be precisely measured.

Ferromagnetic materials are stuck on the belt surface by a magnetic force source 612 and are discharged through a discharge port 652 on the outside of the magnetic field. Powder drops in the direction (b) and enters the rotary sieve 73 of the part 63. The small grain size powder is discharged through a discharge port 653. Non-metals are discharged in the same direction by the rotary cylinder 71 of the part 64 which rotates together with the sieve 73 and non-magnetic metals are discharged through a discharge port 654 and are blown  up other than light powder by a fan 68. With the above-mentioned constitution, the size is reduced, fine quality scraps are recovered by applications, and the dropping and scattering during transporting are prevented.

Abstract: PURPOSE:To prevent an edge-face reflecting film from creeping to the periphery of an electrode by forming a silicon nitride film on the edge face of a laser- diode element by high-frequency sputtering, to provide the edge-face reflecting film and subjecting an electrode forming surface to dry etching. CONSTITUTION:Laser-diode bars 1, on edge faces of which edge-face reflecting films composed of a silicon nitride film are attached through a sputtering method, are set to a cathode electrode 8 for a reactive sputtering-etching device, Freon-gas plasma is generated between the cathode electrode and a counter electrode 9, and the laser-diode bars 1 are dry-etched. When etching is conducted under the state, the silicon nitride films adhering on the edge faces are not etched and left from the characteristics of reactive sputtering-etching, and only the silicon nitride films creeping to the electrode side are removed. Accordingly, the silicon nitride films as the edge-face reflecting films creeping to the electrode side can be got rid of completely, and a heat sink and laser-diodes are bonded perfectly, thus also lowering electric resistance, then also reducing thermal resistance.

Title: Offset printing apparatus
Inventor: HIRANO YOSHIYUKI
IPC: B41F13/08
Filed: 1989-03-30
Abstract: PURPOSE:To adjust the length where an object to be printed is applied with the printing pressure thereby to meet various printings different in the printing depth by a method whereby the distance when a brancket cylinder and a form cylinder, and the formed and a pressure cylinder are in contact with each other is set to be smaller than the width of a recessed portion of said brancket cylinder, and said brancket cylinder is arranged to be detachable from said form cylinder and pressure cylinder. CONSTITUTION:When the leading edges of recessed portions 7, 14 of a brancket cylinder 8 and a pressure cylinder 6 come to agree with each other, the brancket cylinder 8 is moved in contact with a form cylinder 1 and the pressure cylinder 6. Although a paper 15 is sent between the cylinders 6, 8, it is not printed since it agrees with the recessed portions 7, 14. Thereafter, when each terminal edge of the recessed portions 7, 14 passes the contacting position, printing is started and continued until the leading edges of the recessed portions 7, 14 are brought into contact with each other again. Since the contacting position between the brancket cylinder 8 and form cylinder 1 coincides with the recessed portion 14, the ink is never supplied to the brancket cylinder 8 irrespective of the phase of the form cylinder 1.

Abstract: PURPOSE: To surely perform moving of belt material at a constant speed by providing a recess for releasing the contact of capstan and gear to the gear provided coaxially to the pinch roller and delaying the pressure-contact timing of the pinch roller with respect to the start timing of the motor.  
     CONSTITUTION: In the operating device of a pinch roller with moves the recording belt material of a cine camera together with a capstan shaft, a pinch roller is freely rotatably mounted to the shaft 20 at one end of the moving member 19 and a notched gear 25 having a toothless recess 25 at a part is fixed to the shaft 20. When the moving member 19 is turned about a fulcrum axis 21 at the time of moving the belt form member shown by a dot-dash line, the pinch roller 18 moves right upward. This movement causes a switch 30 to go ON to start a motor 12. Then, a flywheel 11, capstan shaft 15 and gear 16 rotate, causing the notched gear 25 and gear 16 to intermesh and rotate. When the toothless recess 25a comes to oppose to the gear 16, the pressure contact blocking state of the capstan 15 and pinch roller 18 is released and both make pressure contact with each other and multually rotate, thereby moving the belt material at a constant speed.
