Title: Oil-impregnated porous ceramic ball
Inventor: ICHIKAWA YUKITO
IPC: A61N5/06
Filed: 1987-08-10
Abstract: PURPOSE:To produce the titled ball superior in lubricity together with the superior characteristics of rolling, load-resistance and abrasion by making the pores smaller and the strength higher in the surface side of layer than in the inside layer in porous balls consisting of the specified ceramic sintered layer having >=2 layers, and impregnating the pore part with a lubricating oil. CONSTITUTION:The ceramic-sintered-body raw-material (e.g.; silicon nitride) powders having <=1-50mum mean particle diameter are incorporated and mixed with an auxiliary sintered agent (e.g.; yttria), binder (e.g.; insoluble cellulose) and water, and the mixed raw materials are formed to spheric bodies through the extrusion by using a tug mill, and the formed body is dried. This formed body is covered with the powder obtained by mixing the sintered body raw material having <=1mum particle diameter, auxiliary sintering agent and water, and spray-drying and then granulating. This covered particle is formed to spherical ball by a press machine, and the spherical ball is degreased, calcined, and polished. Then, the polished ball is immersed in the lubricating oil under vacuum and further impregnated the lubricating oil by heating under normal and increased pressures. Thus, the titled ball consisting of the ceramic sintered body having >=2 layers of continuous pores and of different pore size and open porosity is produced.

Title: Method of forming pattern
Inventor: KITO MAKOTO
IPC: H01L21/027
Filed: 1988-08-12
Abstract: PURPOSE:To eliminate loss, lack and deformation of a pattern due to the separation of resist and improve pattern accuracy by using an aluminum-containing carbonic thin film having excellent ion trimming resistance and resistance to separation as resist. CONSTITUTION:An aluminum-containing carbonic thin film 3 is formed on the surface of unprocessed substrates 1, 2. An organic polymer thin film 4 containing silicon is formed thereon. A predetermined section of the film 4 is irradiated with high-energy beams such as light or electronic beams. The film 4 is developed and the film 4 in the section other than required is removed. The aluminum-containing carbonic thin film 3 exposed on the surface is removed using oxygen-chlorine mixed plasma. Using the pattern of the aluminum- containing carbonic thin film 3 as a mask material, a substrate is processed by plasma etching, etc. That is, because aluminum has a larger atom radium than that of carbon, residual distortion can be suppressed and it has excellent contact with permalloy, Au, Pt, etc., than carbon. This makes it possible to prevent the separation between an etching material 2 to be processed and the carbonic thin film 3 and to eliminate the loss, lack and deformation of a pattern.

Title: Car washer
Inventor: SHINOZAKI KAZUAKI
IPC: B60S3/06
Filed: 1997-07-25
Abstract: PROBLEM TO BE SOLVED: To prevent a bristle material from being contaminated by the contact with a car washer set surface, or frozen and adhered in cold time when the rotation of a rocker brush is stopped by vertically raising and lowering the rocker brush having a substantially vertical rotating shaft according to preset conditions. SOLUTION: In this car washer, the rod part of an air cylinder is contracted when no car wash is performed to contract the rotating shafts 34a, 34b of the rocker brush 21, so that the setting surface of the car washer is prevented from making contact with the bristle material 37 of the rocker brush 21. When the rocker brush 21 is rotated at the start of a car wash, the bristle material 37 of the rocker brush 21 is swollen by centrifugal force, and the car washer extends the rot part of the air cylinder, so that the bristle material 37 can be sufficiently worked to the lower part of an automobile A. In no car wash, the bristle material 37 of the rocker brush 21 is prevented from making contact with the setting surface of the car washer.  Thus, the setting surface of the car washer can be prevented from being contaminated with sludge or residual wash water by the contact with the bristle member 37, or the bristle member 37 can be prevented from being frozen together with the residual wash water.

Abstract: PURPOSE:To prevent data in a data latch circuit from being damaged by power noise by providing at least one inverter in the preceding stage of a first transfer gate. CONSTITUTION:When the potential level of a second power source Vcc2 is made lower then that of a first power source Vcc1 by DELTAV more than a normal threshold ¦VTkappa in the data holding period because of the power noise of another circuit, an output signal B of an inverter 5 of a data latch circuit 2 goes to (the high level)-DELTAV. With respect to levels of three terminals of a PMOS transistor 6, the source S goes to (the high level)-DELTAV, and the gate G goes to (the high level)-DELTAV, and the drain D goes to the low level. Thus, the transistor 6 is not turned on in the case of ¦VGS¦>¦VT¦. Consequently, the malfunction of the circuit 2 is prevented.

IPC: H04N1/40
Filed: 1989-08-02
Abstract: PURPOSE:To improve the operability by constituting the reader so that sampling of shading correction data can be omitted in accordance with a prescribed condition. CONSTITUTION:The reader is provided with a shading data RAM 409 and a shading correction table RAM 415, brings shading correction data to sampling before reading an image of a light transmission document, and executes a shading correction to output data of a CCD 27 by using the data brought to sampling.

However, the time is counted from the start time of a light transmission document copy operation of the previous time, and when a prescribed time elapses, the contents of the RAM 409 are set to '0', that is, the shading data is eliminated. In such a way, the operability is improved.

Title: Magnetic recording medium and its production
Inventor: ISHIZAKA YASUO
IPC: G11B5/706
Filed: 1985-09-11
Abstract: PURPOSE:To attain the recording with intensive residual magnification having a prescribed slope within a recording medium by tilting the direction of easy magnetization of a magnetic matter by a prescribed angle to a normal line of the medium surface and therefore approximating the slope of a line of magnetic force within the medium to that of an easy axis of magnetization. CONSTITUTION:A target 6 contains an Nb or Ta pellet put on a Co-Cr alloy of a prescribed composition factor. A room 5 is exhausted under vacuum and a Co-Cr-Nb or Co-Cr-Ta thin film is sputtered while a heat-resistant polymer film 9 is driven. For production of a magnetic thin film having the direction of easy magnetization tilted by a prescribed angle theta0 to the normal line of a medium surface 17. Thus the recording is possible with large residual magnetization because the direction of easy magnetization gets close toward a line of magnetic force of a core that contributes directly to the recording. Furthermore a produced pattern of magnetization produces no demagnetizing function between the adjacent patterns. Then a field of demagnetization is reduced with increase of the recording density.

Abstract: PURPOSE:To equalize a light quantity distribution of a light source device by providing a photodetecting part of an optical fiber bundle on an irradiating area of a reflected ray by a reflector, in the vicinity of the second focus of a reflector of a rotating elliptical body shape. CONSTITUTION:When light of a light emitting source 11 provided on a focus F1 of a reflector 10 of a rotating elliptical body shape is reflected by the reflector 10, it is condensed to the second focus F2.
