IPC: B32B15/04
Filed: 1990-05-07
Abstract: PURPOSE:To shorten the time for working by molding mask materials on the surfaces of a heat resistant ceramics base material exclusive of the surface to be formed as a reflecting surface, then coating the reflecting surface with an SiC film by a CVD method, optically polishing the reflecting surface and further depositing a metallic film by evaporation on the reflecting surface. CONSTITUTION:The mask materials 4 are molded on the surfaces of the heat resistant ceramics base material 1 exclusive of the surface to be formed as the reflecting surface and thereafter, the reflecting surface is coated with the SiC film 2 by the CVD method and this reflecting surface is optically polished; further, the metallic film 3 is deposited by evaporation thereon. The mask materials 4 to be formed on the surfaces of the base material 1 exclusive of the surface to be formed as the reflecting surface are exemplified by the materials of the shape to cover the surfaces exclusive of the reflecting surface by being fitted to the heat resistant ceramics base material 1. A metallic film of Pt or Au formed on, for example, a Cr underlying layer is exemplified as the metallic film 3. The build-up forming of the SiC film in the ridge parts of the base material 1 is, therefore, obviated. The time for the polishing process is shortened in this way.

Title: Rear wheel brake control device
Inventor: KOYANO HITOSHI
IPC: B60T8/32
Filed: 1997-05-08
Abstract: PROBLEM TO BE SOLVED: To easily apply a pressure reduction gradient in accordance with movable load in simple constitution. SOLUTION: A vehicle loading condition is estimated based on a vehicle deceleration (g) determined based on wheel speeds from wheel speed sensors 19, 19', 20, 20' and a master cylinder pressure (MCY) pressure PM from a MCY pressure sensor 21 in normal brake actuation, and a valve control MCY pressure PMO in closing a solenoid valve 26 is determined based on the loading condition. As the MCY pressure PM is increased to reach the valve control MCY pressure PMO, an opening valve 35 is closed. After this, a pressure reduction control piston 29 moves right by increase of the MCY pressure PM, with a W/C pressure PW also increased. The W/C pressure PW at this time is pressure reduction- controlled in accordance with movable load.  When the opening valve 35 is closed in an early stage at the time of sudden braking, in the case where a W/C7 is not substantially actuated, brake fluid is supplied to the W/C7 by actuation of the pressure reduction control piston 29, thereby decrease of the W/C pressure PW is prevented.

Title: Lens shutter for camera equipped with flashing device
Inventor: TOMA KIYOSHI
IPC: G03B9/10
Filed: 1993-05-20
Abstract: PURPOSE:To obtain an excellent subject by setting the timing of the flashing of a flash in a stage where a shutter blade closes an aperture for exposing, in a lens shutter for a camera. CONSTITUTION:An exposure condition setting device 1 calculates the timing of the opening/closing actions of opening/closing shutter blades and the flashing of the flash and issues a signal to a control circuit 3. The reciprocating motion of the closing shutter blade is taken by the forward/backward rotations of a pulse motor 11. On the other hand, the reciprocating motion of the opening shutter blade is taken by the reciprocative turn of a moving magnet type motor 18. The flashing part 8 flashes via a flashing circuit 7 with the flashing signal of the flash. The peak of the flash light at this time is in the stage where the aperture for exposing is closed by the closing shutter blade.

Title: Insulated gate type field effect transistor and manufacture thereof
Inventor: IWAHASHI HIROSHI
IPC: H01L29/78
Filed: 1980-08-28
Abstract: PURPOSE:To enable the high speed operation of a field effect transistor by decreasing the extending amount of source and drain regions under gate electrodes. CONSTITUTION:When a source 17 and a drain 18 are formed, the extending  amounts of the source and drain regions under the polysilicon layer 13 of these regions becomes approx. 80% of the depthwise extension in a substrate 11, but since the layer 13 is etched to contract its width, the extensions of the source 17 and drain 18 under the polysilicon layer (a gate electrode) 13 becomes shorter than the 80% of the depthwise extension in the substrate 11. Accordingly, capacities C2, C3 become small, thereby enabling the high speed operation of an IGFET circuit. Since the depths of the source and drain regions can be sufficiently increased, the resistance of these regions can be decrased, and the punch-through phenomenon of the electrodes can be prevented.

Title: Plate width controller
Inventor: IMANARI HIROYUKI
IPC: B21B1/26
Filed: 1999-04-27
Abstract: PROBLEM TO BE SOLVED: To efficiently control width by means of tension. SOLUTION: With a tandem rolling mill having rolling stands 2 (2a, 2b,...), a tension-width control means 18 takes in measured values of plate width from a rough delivery-side width gauge 9 and a delivery-side width gauge 11, calculates such a tension correction value that the plate width on the delivery side will be a width target value decided by a setting means, adds it to a tension target value decided by a setting means, and gives it as a tension command value to a reduction tension control means 13. The reduction tension control means 13 takes in the rolled material tension value measured by tension detectors 7, determines such a roll gap opening as to be the tension command value, and gives it to reduction controllers 8 (8a, 8b, 8c) to control the tension of the rolled material 1, thus making it possible to make the width control by tension efficiently.

Title: Heat exchanger
Inventor: KOUTATSU HOMARE
IPC: F28F1/32
Filed: 1998-04-28
Abstract: PROBLEM TO BE SOLVED: To braze a fin and a tube other without applying a brazing filler metal over the whole surface of either one of them. SOLUTION: A fin 130 and a tube 110 are brazed to each other using a brazing filler metal 300 applied to the inner side of a bend part 131. Since the dimension between the fin 130 and the tube 110 is not increased when the brazing filler metal is melted, the tube 110 and the fin 130 can be easily laminated and assembled to facilitate assembling of a heat exchanger. Further, since the brazing filler metal is left behind mainly in the vicinity of the bent part 131, most parts of the fin 130 and the tube 131 are not covered with the brazing filler metal, and the brazing filler metal is not diffused when heated during brazing. Thus, the capacity of the heat exchanger can be improved, and generation of erosion can be prevented even when the thickness of the fin 130 and the tube 110 is reduced.
