Abstract: PURPOSE:To prevent cracking of the stock, to reduce the machining time, and to increase the service life of tools by forming a gear through swaging and spinning after heating the outer circumferential part of the stock in the prescribed temperature range. CONSTITUTION:A blanked circular stock 1 is held at the axial center side away from the outer circumferential part 1a by a fixing table and a pressing plate 3, and fixed. Positioning is made by fitting a positioning pin 4 provided on the axial center of the fixing table 2 to the axial center of the circular stock 1. A part 1a to be swaged is induction heated to 400-500 deg.C, and the part 1a to be swaged of the stock l is swaged in the axial direction. The part of large wall thickness is spun to provide a roughed gear 8 whose sectional shape is angular at the part. The gear 8 is finished by a spinning dies for finishing gears. The gear part is hardened as necessary. This constitution reduces the machining process, and forms the gear without causing cracking in the outer circumferential part.

Abstract: PURPOSE:To prevent a silicide film from being oxidized abnormally, to prevent a film from being stripped and to prevent particles from being produced due to it by a method wherein a photoetching process used to remove a silicide layer at the peripheral part of a semiconductor wafer is added before a process used to form a polycide gate electrode. CONSTITUTION:An Si oxide film 2 and a poly-Si layer 3 are formed sequentially on an Si substrate 1, a high-melting-point metal silicide layer 4 is laminated on them, the silicide layer 4 and the poly-Si layer 3 are then etched by making use of a resist layer 5 as a mask, and a gate electrode 6 is formed. Then, the resist layer 5 is removed, an oxide film 7 is deposited on the whole face so as to cover the gate electrode 6, the whole face is then etched back, and an oxide-film sidewall 7a is formed on the side face of the gate electrode 6. When a semiconductor device provided with a polycide gate electrode is manufactured in this manner, a photoetching process used to remove the silicide layer 4 at the peripheral part of a semiconductor wafer is added before a process used to form the gate electrode 6.

Title: Picture processing unit
Inventor: YAMAKAWA SHINJI
IPC: H04N1/387
Filed: 1990-04-02
Abstract: PURPOSE:To attain excellent void data processing to a natural picture by applying void data processing to an input picture data after the end of mosaic processing. CONSTITUTION:A mosaic picture data subject to mosaic processing by a mosaic processing means is a binary data (1 bit) by a binary processing section 41, stored by n-lines in a line memory 42 and inputted to a void data processing logic 43. Any of color data 1, 2 is selected by a selector 44 based on the result of output. When a void data for processing void is not outputted, the color data 1 is selected. Since the data processing logic 43 has a thick processing function and a thin processing function, one optional kind of the result of output has only to be selected.

Title: Cleaner, process cartridge, and electrophotographic image forming device
Inventor: MURAYAMA KAZUNARI
IPC: G03G21/00
Filed: 1998-03-16
Abstract: PROBLEM TO BE SOLVED: To maintain cleaning performance with respect to small diameter, fine particle developer over a long period till the end of the service life of an electrophotographic photoreceptor. SOLUTION: A device has a cleaning member 16 which scrapes developer off an electrophotographic photoreceptor, and a scraping member 60 which is disposed upstream from the cleaning member 16 in the direction of the rotation of the electrophotographic photoreceptor and scrapes the developer from the electrophotographic photoreceptor by rotating motion. Here, the number of rotations of the scraping member 60 is made smaller than that of the electrophotographic photoreceptor. This way, the scraping member 60 exerts a sufficient scraping force when scraping the developer from the electrophotographic photoreceptor, because the scraping member 60 rotates with the number of rotations smaller than that of the electrophotographic photoreceptor.  Further, the number of the rotations of the scraping member 60 that is smaller than the number of rotations of the electrophotographic photoreceptor prevents excessive load on the drive transmission mechanism of the scraping member 60 and makes it possible to endure long-term service and to maintain its cleaning performance over a long period.

Title: Magnetic head
Inventor: SAKURAI HIROSHI
IPC: G11B5/187
Filed: 1981-06-05
Abstract: PURPOSE:To prevent a tape from damaging by terminating grooves, used for aerodynamically controlling a floting gap provided on the surface of a head facing a recording medium, smoothly at points inside of the ends of the surface. CONSTITUTION:A magnetic head consists of a magnetic core part 5 and a slider part 7 having an arc surface 7' for floating a magnetic tape aerodynamically. In the arc surface 7' of the slider part 7 facing the magnetic tape, two grooves 6 are made. Those grooves 6 are provided for controlling the floting gap of the magnetic tape, and both ends of each groove 6, i.e. entrance and exit ends for an air flow are terminated smoothly to the arc surface 7' at points inside of the ends of the arc surface 7'. Therefore, even if the magnetic tape is bitten into the gap part between a rotor and the magnetic head, the possibility that the magnetic tape damages is reduced greatly. The influence of the shortened lengths of the grooves 6 upon the flating state of the magnetic tape and upon electromagnetic transducing characteristics is removed by adequately adjusting the extent of head deep work and that of groove depth work.

IPC: G05D1/02
Filed: 1988-04-07
Abstract: PURPOSE:To use only one feedback system by directly detecting the direction of a driving wheel by a gyroscope and traveling the driving wheel on a straight track. CONSTITUTION:A steering motor 6 is controlled by a straight traveling control means 16 to travel a moving body. An angle deflection arithmetic means 17 and a distance deflection arithmetic means 18 respectively compute an angle deflection theta and a distance deflection (x) (theta=0 and V=0 at the initial time). A decision means 21 compares the deflection (x) with a fixed value (a), and when the moving body goes far from the straight track, rotates motor 6, turns the driving wheel 2 to the straight track at a fixed angle and stores a deflection x'. When the traveling track is deflected right or left, a decision means 20 compares the angle deflection theta with a fixed value alphaand turns the driving wheel 2 to the straight direction theta=0. When the arithmetic operation of theta and (x) and the motor 6 is controlled by the means 16, the driving wheel 2 goes straight on the straight track while being corrected and the body 1 is also traveled on the straight track. Consequently, the moving body can surely travel straight without external guide by means of a control system omitting the direction of body direction and using only one direction controlling feedback system.
