Title: Magnetic recording medium
Inventor: KONNO AKIHIKO
IPC: G11B5/73
Filed: 1994-06-17
Abstract: PURPOSE:To improve recording and reproducing characteristics in a high density recording region by interposing a nonmagnetic layer consisting of SnO2 stuck TiO2 particles and a binder between a nonmagnetic substrate and a magnetic layer. CONSTITUTION:A nonmagnetic layer 2 is interposed between a magnetic layer 3 and a nonmagnetic substrate 1. Since the nonmagnetic layer 2 functions as an adhesive layer between the substrate 1 and the magnetic layer 3, the magnetic layer 3 is tightly bonded to the substrate 1, and at the time of sliding on various sliding members, the dropping of magnetic powder from the magnetic layer 3 and the peeling of the magnetic layer 3 are prevented and durability is ensured. When the magnetic layer 3 formed on the nonmagnetic layer 2 is calendered so as to smoothen the surface, the nonmagnetic layer 2 is intensely crushed, calendering effect is enhanced and such high surface smoothness as to attain high density recording can be imparted to the surface of the resultant medium.

Title: Diffusing method of aluminum
Inventor: MATSUDA YASUHIDE
IPC: H01L21/22
Filed: 1978-11-06
Abstract: PURPOSE: To prevent the sputtering of Al-Si alloy when Al is diffused into Si by using Al or an alloy the main component of which is Al by attaching the diffusion source to Si and by making the speed of temperature rise 50°C/min or less while heated.  
     CONSTITUTION: Al, which is of p-type, is vacuum-evaporated on the n-type Si substrate in the thickness of about 1μm, the Al layer is regulated to a fixed shape by photoresist technique. It is sufficiently washed, put in the electric furnace in which temperature is kept at 570°C, and is heated up to 1250°C on controlling the speed of temperature rise 50°C/min or less. In this way, the remained cleaning liquid is vaporized before the viscosity of Al-Si alloy drops, the sputtering of Al- Si alloy is not produced. When the temperature exceeds 660°C, that is, the melting point of Al, the said speed can be made greater than 50°C/min.

Title: Supporting structure for clutch hub
Inventor: SUWA HIROTADA
IPC: F16H57/02
Filed: 1997-05-12
Abstract: PROBLEM TO BE SOLVED: To suppress changing in an attitude of a clutch hub, attain extending of a life of an adjacent thrust bearing. SOLUTION: A clutch hub 31 is provided with an outer/inner side cylinder part 32, 34 extended mutually in the same direction from a bottom wall 33. In a peripheral surface of the inside cylinder part, a spline 37 is formed, to be engaged with a spline in an internal peripheral surface of an inner race 21 of one-way clutch, the clutch hub and the inner race are connected together.  In this way, even when a space of a fitting part of an insertion hole 38 in an output shaft 10 of the clutch hub is increased, displacement in the diametric direction of the clutch hub 31 is hardly generated, and since a distance between a load point by dead weight of the outside cylinder part 32 and weight of a friction plate and a support point by the inner race 21 is shortened, and generation of the displacement is prevented even if tumbling, a wrench is prevented from being generated in a thrust bearing 48 supported on a protrusion part 35 of the clutch hub.

Title: Gas metal arc welding method
Inventor: MATSUYAMA OSAMU
IPC: B23K9/16
Filed: 1982-08-04
Abstract: PURPOSE:To enable welding in all attitudes with high efficiency without defects such as lack of penetration in gas metal arc welding by heating the work with an auxiliary heat source. CONSTITUTION:A welding torch 2 is disposed oppositely to the work 1, and a filler wire 3 and a non-consumable electrode 4 which is an auxiliary heat source are mounted to the torch 2. Electric current is flowed to the electrode 4 to generate an arc and to heat supplementally the work 1; at the same time, electric current is flowed to the wire 3 to generate an arc and to weld the work 1. The welding current is controlled independently from the feed speed of the non- consumable wire and the lack of penetration is prevented by combining the auxiliary heat source using the non-consumable electrode in the above-mentioned way.

Filed: 1995-06-02
Abstract: PURPOSE: To obtain a video signal with high image quality having provision for multimedia by discriminating a dynamic image or a still image and controlling a luminance signal processing and a chrominance signal processing depending on the result of discrimination. CONSTITUTION: Two systems of signals read from an image pickup element 101 are A/D-converted by A/D converters 106, 107, from which a digital signal is obtained.

Abstract: PURPOSE: To secure floating of a caliper for transmitting reactions and facilitate a countermeasure to prevent rusting by peripheral revolution of a pin and a boss, also to increase pinching force of friction pads against a disk by receiving a torque of the caliper upon braking.  
     CONSTITUTION: When hydraulic pressure is delivered into an oil chamber 6, a piston 7 is forwarded in a cylinder 5 and an inner friction pad 9 is pushed against a disk 1. Due to a reaction force thereof, a caliper 2 oscillates around a supporting pin 14 and a leg portion 4 pushes an outer friction pad 10 against the disk 1, and thereby, the disk 1 is braked by the friction pads 9, 10. Brake torque generated in the friction pads 9, 10 acts as a moment rotating the caliper 2 in a direction shown by an arrow sign B. A guidance of the oscillation of the caliper 2 is effected by only a relative peripheral rotation between the supporting pin 14 and a boss portion 13 of a caliper 2, and sealing thereof may be effected easily by providing seal rings 17, 18.

Abstract: PURPOSE:To accurately execute the substance pick-up operation with a transfer means through compensation for the positioning operation for substance placed just under the transfer means by detecting displacement of substance located on the positioning means from the specified location with a position recognizing means. CONSTITUTION:A pick-up table 2 is shifted adequately and thereby a point indicated as I in the figure is aligned with the specified point within the sight of a camera 13 of the position recognizing means. Next, only the pick-up table drive motor 3B is driven, thereby the pick-up table 2 shifts in the left direction for the distance integer times the arrangement interval of many pellets 5 and stops at the position aligning with the point II in the fiture at the specified position of sight of cameral means 13. A control unit 14 calculates a value of deviation angle theta from the distance between two points of II and III and a shifting distance (distance between two points of I and II) of the pick-up table 2 and holds such value. A pick-up arm 12 picks up a pellet 5 and increases or decreases the vertical shifting distance for DELTAy=xtantheta for the lateral shifting distance (x) of the pick-up table 2 on the occasion of shifting the pellet 5 to the specified position and thereby said displacement can be corrected.
