摘要： PURPOSE:To obtain a removing method for coating of insulator coating without residue by removing the coating from a metal wire by alternately supplying bidirectional pulse currents having different polarities between the insulator- coated metal wire and a discharge electrode, and forming an arc discharge of the wire in a nonmelted state. CONSTITUTION:Bidirectional pulse currents having different polarities are alternately supplied between an insulator-coated metal wire 2 and a discharge electrode 1, an arc discharge 7 of the metal wire 2 of a nonmelted state is formed, and an insulator coating 4 is removed from the wire 2. For example, an interval between a polyurethane-coated gold-plated Cu wire (OFC, 50mum of diameter) 2 and the electrode 1 is set to 0.05-0.1mm by using an Ag-W electrode. As a step of removing an insulator coating layer 4, a pulse current of 3500V, 150mA, 10msec is supplied between the electrode 1 as a positive side and the wire 2 as a negative side. As cleaning of the electrode 1 and heat treating of a metal wire 5, a pulse current of 50V, 0.1A, 50msec is fed between the electrode 1 as a negative side and the wire 2 as a positive side, and they are alternately continuously repeated 120 times.

摘要： PURPOSE:To prevent occurrence of failures due to abrasion powder, by preventing production of abrasion powder due to the contact between a large magnetic disc as a workpiece to be incorporated in the above-identified mechanism and a spindle as a member to be incorporated. CONSTITUTION:A workpiece 1 is set on a workpiece receiving seat 9 in a workpiece positioning section 2 so as to be positioned. Then, an assembling handle 16 is made to approach a receiving seat 5 so as to set a guide block 17 on a level surface of the receiving seat 5. Thereafter, a frame 25 is made to approach the receiving seat 9 to move a workpiece gripping and releasing means 36 to a workpiece gripping position. Then, the entire assembling handle 16 is moved to a position where a member 64 to be incorporated is set. Further, the guide block 17 and a guide shaft 19 are positioned with respect to the member 64 to be incorporated. After the workpiece 1 is moved to its incorporating position, the workpiece gripping and releasing means 36 is operated so as to release the workpiece 1, and therefore the workpiece 1 is assembled at a predetermined position in the member 64 to be incorporated.

摘要： PURPOSE:To eliminate a rotation wait time and to speed up operation by arranging index data at an address position shifted from the start address of servo pattern data and starting comparison with verification data corresponding to the position. CONSTITUTION:An MPU1 writes servo pattern and verification data in a servo pattern memory 2 while specifying addresses by an address counter 9, and then reads out servo patterns successively to write them on a servo disk 6 by a servo head 5 through a write circuit 3 and an R/W amplifier 4. A read verifying circuit 7, on the other hand, compares read data from the amplifier 4 with the verification data from the memory 2. At this time, the verification data is read out of an address (n) and an offset value (n) is outputted from an address counter offset circuit 9 to the counter 8 only in read verification processing. Then, the circuit 7 compares the verification data with the servo pattern data to inform the MPU1 of whether an error occurs or not.

摘要： PURPOSE:To enable to reduce the rate of misreading, by calculating the similarity of the pattern in the buffer area and the standard pattern with the similarity calculation circuit, and detecting the maximum. CONSTITUTION:The demarcation processing section 100 demarcates the video data into the character pattern of one character, it is fined at the character pick up circuit 200 to pick up the derectivity of connection and to normalize the size, and the gradation processing circuit 300 reads in the pattern in the buffer area to perform gradation processing to each pattern. Next, the similarity calculation circuit 400 reads in the pattern in the buffer area to calculate the similarity with each of the standard patterns stored in itself. The maximum similarity is detected and the main computer 70 writes in the result of recognition in the floppy disc 500 in given format. Thus, the rate of misreading can be reduced.
