Title: Improvement of covering power of cationic electrodeposition paint
Inventor: HIRATA YASUYUKI
IPC: C25D13/06
Filed: 1988-05-31
Abstract: PURPOSE:To efficiently improve the covering power of cationic electrodeposition paint at a low cost by subjecting the paint to vacuum steam distillation to reduce the amt. of a low b.p. org. solvent contained in the paint to a specified content. CONSTITUTION:Cationic electrodeposition paint inevitably contains a low b.p. org. solvent used to produce the compsn. The amt. of the solvent such as alcohol is reduced to <=1wt.% by vacuum steam distillation. This distillation can be carried out by charging the paint at about 10-60 deg.C in to a packed tower under about 20-100mmHg pressure from the upper part of the tower and feeding steam at about 30-60 deg.C from the lower part of the tower. The pref. ratio between the flow rate of the paint and that of steam is about 1:5-1:20. Cationic electrodeposition paint having satisfactory covering power and capable of forming a paint film having superior corrosion preventiveness and smoothness on a bag-shaped structure is obtd.

Title: Manufacture of semiconductor device
Inventor: KAIDA NAOHIKO
IPC: H01L21/3205
Filed: 1979-10-13
Abstract: PURPOSE:To prevent the abnormal generation of projections of Al through heat treatment by a method wherein after the formation of a thin Al film for inside wiring, thin fine-grained films are laminated under low temperature for controlling the movement of Al particles. CONSTITUTION:On the thin Al 5 for inside wiring is formed a thin SiO2 film 8 by spattering under the low temperature at which the fautly projections of Al are not caused. Thereafter the alloying of the Al film 5 and a diffusion layer 2 and the formation of a protection film 6 are performed by heating in the same way as usual. Since the movement of the Al particles of the Al film 5 is controlled by the fine- grained SiO2 film 8 in this constitution, the faulty projections are not produced. In addition to SiO2, a thin film of Al2O3 is also effective, and thereby the generation of the deterioration or inferiority of the characteristics of the semiconductor device caused by the abnormal projections of Al can be prevented.

IPC: G11B5/60
Filed: 1982-07-31
Abstract: PURPOSE:To eliminate the need to set the angle of a magnet chuck, etc., and to obtain a high-precision head core, by interposing a special jag between the head core and magnet chuck without attaching the head core directly to the magnetic chuck. CONSTITUTION:A head core material 7 is fixed temporarily in close contact with the intersecting state part 4 of the jig 3 for head core attachment, and plural materials are attached to a working jig 6 threadably. The working jig 6 is mounted on a plane polishing machine to polish the top surface of the head core 7 as prefihishing. Then, the jig 3 is detached from the working jig and set to the magnet chuck 8 by pressing the 3rd surface 3c (side CD) of the jig 3 against the side surface 9a of a reference plate 9 perpendicular to the surface 3c. Consequently, one side AF of the intersecting stage part 4 of the jig 3 slants to the surface of the magnet chuck 8 at a fine angle 30', so the angular mirror surface part 7b with the angle 30' is worked on the top surface 7a of the head core material 7 by a cup-shaped resinoid grindstone 10.

Title: Production of dead-soft carbon steel
Inventor: OBANA TOMOYUKI
IPC: C21C7/10
Filed: 1990-05-24
Abstract: PURPOSE:To securely obtain the desired carbon content by previously determining the computed values of CO concentration in exhaust gas in the case where the desired carbon content is presumed to be obtained and finishing decarburization at the time when the measured values of CO concentration in exhaust gas with respect to respective decarburization treatment times reach the computed values or below, respectively. CONSTITUTION:A dead-soft carbon steel is produced by using vacuum degassing equipment. At the time of carrying out decarburizing refining, the computed values of CO concentration in exhaust gas in the case where the desired carbon content is presumed to be obtained are previously determined with respect to respective decarburization treatment times. Decarburization is finished at the time when the measured values of CO concentration in exhaust gas with respect to respective decarburization treatment times reach the computed values or below, respectively. By this method, decarburization treatment time can be shortened, and this method can greatly contribute to the reduction in manufacturing costs.

Title: Recording and reproducing device
Inventor: KAWASAKI NOBORU
IPC: G11B17/32
Filed: 1989-05-30
Abstract: PURPOSE:To always obtain an optimum head touch wherever a transducer is positioned in either inner circumferential side or outer circumferential side of a recording medium by generating more negative pressure on a stabilizing plate with an inner circumferential position of the recording medium than an outer circumferential position. CONSTITUTION:The stabilizing plate 18 has a bottom plate 21 provided with a head inserting hole 20 in the center and an ellipsoidal wall part 19 formed erectly on the outer periphery of this bottom plate 21. With the stabilizing plate 18 erected with the wall part 19, a generating amt. of negative pressure due to an airflow is mainly proportional to a distance between a position and the wall part 19 measured in the direction of the airflow. Consequently, large negative pressure is generated by the stabilizing plate 18 with the recording medium on the inner circumferential side which is required comparatively large negative pressure, and as the position is moved toward the outer circumferential side, the negative pressure generating amt. is gradually decreased, while on the outer circumferential side, the min. negative pressure is generated by the stabilizing plate 18. By this method, wherever a magnetic head 17 is positioned, the proper head touch always is obtained.

Since the distance between the two markers 4A and 4B can be taken relatively large, the measurement accuracy is improved. The azimuth angle of the high accuracy is obtd. in this way and the yield of the production and assembly is improved.

Title: Device for regulating quantity of fuel-air mixture
Inventor: SHIMOMURA SETSUHIRO
IPC: F02M51/02
Filed: 1981-08-25
Abstract: PURPOSE:To provide a mixture quantity regulation device in which the pressure at a region most restricted by an air restrictor valve interlocked with an accelerator pedal is detected to calculate fuel pressure to regulate fuel by a fuel control valve so that a mixture is increased for acceleration, without delay. CONSTITUTION:Fuel is discharged into a region A through passages 2-4, 2-6 and atomized and mixed with the flow of air. A spring 2-7 acts to push an air restrictor valve 2-2 in a direction for closing. The flow of air is restricted by releasing an accelerator pedal 1. An electric controller 3 calculates the velocity of the air flow on the basis of the output P1 of a pressure detector 4 and then calculates required fuel pressure P2 on the basis of the air flow velocity and the pressure level P1. An electric signal corresponding to the required fuel pressure P2 is supplied to a fuel pressure controller 5 to provide the fuel pressure P2 to attain a prescribed air fuel ratio. The rate QA of the air flow is drastically increased by the sharp depression of the accelerator pedal and thereafter gradually increased with the rise in the rotational frequency of the engine.

Title: Small-sized electromagnetic clutch mechanism
Inventor: TAKEKOSHI TARO
IPC: F16D27/112
Filed: 1989-05-29
Abstract: PURPOSE:To reduce cost, prevent reduction of reliability, and keep durability, by forming a yoke by deep drawing, maintaining accuracy of air-gap in connection with a cylindrical member, and providing a flanged portion integrally on the outer periphery of the yoke. CONSTITUTION:A yoke 1 in thin-wall cup-shape can be formed by a simple deep drawing and press working, and these processes are made by a progressive press machine. By this, a cycle time for working a part is low. Also, an accuracy requested for a cylindrical member 2 is air-gap delta, but accuracy control for each part is not made except that accuracy maintenance is made with a jig during the connection with the yoke. Next, a grooved portion engraved in the end surface 1-c of the yoke flange keeps lubricant to prevent durability abnormal wear due to oil shortage. On the other hand, it gives the excellent cut of oil film to prevent a contact surfaces, sliding at high speed, from being separated due to the oil film of the lubricant. Also, since the yoke 1 is made in contact with the absorbing plate 4 at the flange end surface, the contact area is increased remarkably.
