Title: Off-track reducing method
Inventor: AOYAMA SHUICHI
IPC: G11B21/21
Filed: 1992-10-29
Abstract: PURPOSE:To reduce an off-track amount in magnetic disk recording and reproducing with simple operations by performing a contact start stop(CSS) operation before the start of a normal operation after it is detected that a magnetic head runs away on a magnetic disk. CONSTITUTION:When a voice coil motor(VCM) runs away and a pad 11 of a swing arm 8 is powerfully abutted to an inner peripheral stopper 12, a magnetic head 9 is shifted in a direction A to the rotational tangential direction of a magnetic disk 5. When a VCM runaway detection circuit detects the runaway of the VCM, a counter for the number of times of the CSS operation is stopped, a stop signal is outputted from an SPM start/stop supporting circuit to an SPM and after the SPM is stopped, the CSS operation is performed by outputting a start signal to the SPM again and rotating the SPM at prescribed rotating speed. Then, frictional force Hl and H2 in the tangential direction is operated to the head 9, and the posture of the head 9 is corrected so as to be coincident with the track of the disk 5.

Filed: 1988-12-14
Abstract: PURPOSE:To obtain a satisfactorily fixed picture over a long period carrying out the cleaning of a fixing rotary body by carrying a cleaning sheet to the fixing rotary body every prescribed number of times and thereby cleaning a fixing rotary body. CONSTITUTION:The cleaning sheet with an adhesive layer 12 can be obtained by such a way that almost the entire surface copies a black original down a sheet 11 and toner is fixed in the same manner on the almost entire rear surface of the sheet. The material of the cleaning sheet is available if it is able to fix the toner.

Furthermore, since the adhesive layer is not laced on the edges of the cleaning sheet in carrying direction, the sheet can be separated surely from the rolls 1 and 2. In this case, the cleaning sheet is carried to the fixed rolls 1 and 2 every prescribed number of times and the fixed rolls 1 and 2 are cleaned. Thereby, the satisfactorily fixed picture can be obtained over a long period.

Title: Method for preventing development of oxide film generated during heating or hot-working of ti alloy material
Inventor: YARIMIZU SEIICHI
IPC: C23F15/00
Filed: 1996-11-14
Abstract: PROBLEM TO BE SOLVED: To prevent the development of oxide film by coating antioxidant on the surface of a Ti alloy material followed by heating or hot-working. SOLUTION: The antioxidant coated on the surface of the Ti alloy material, a carbide of SiC+B4 C, etc., is suitably used. In the case of using, this agent in a form of suspension, powder, etc., can be sprayed or applied with a brush, etc., on the surface of the Ti alloy material. The reason why the carbide is effective as the anti oxidant, is assumed that the carbide itself is oxidized so as to prevent the oxidation of the Ti alloy material. Further, it is well-known that this carbide is superior in adhesion to the other antioxidant, e.g. chloride.
