Title: Method for machining workpiece with grinding machine
Inventor: KISHINO KAZUHISA
IPC: B24B1/00
Filed: 1998-06-09
Abstract: PROBLEM TO BE SOLVED: To minimize the punch warp caused by grinding and to prevent defective machining such as punch breakage by shortening the moving distance of a grinding wheel at least on the final machining face having the least thickness of a work, and finishing the final working face in multiple stages. SOLUTION: A machining face 4a is first ground by a grinding wheel 3. For the next machining of the machining face 4a, the moving distance of the grinding wheel 3 is shortened, and grinding is applied little by little in stages. The maximum moving distance of the grinding wheel 3 is determined under consideration of the thickness and material of a punch 1 immediately before machining. The punch 1 is machined little by little from the portion on its left side into the final shape, and the machining face 4a is machined in three stages, for example. When machining is applied in stages, a warp rarely occurs on the punch 1, and punch breakage is resolved.

Title: Disk reproducing device for vehicle
Inventor: KAWAMURA KATSUMI
IPC: G11B21/00
Filed: 1986-07-08
Abstract: PURPOSE:To avoid inadvertent injuries of a pickup or a disk by short-circuiting both ends of an actuator in an inactive mode. CONSTITUTION:A control circuit 12 turns off a switch 11 when an end of application is inputted or the power supplied from a battery is cut off due to an OFF state of an accessory switch of a car. Under such conditions, a relay 10 is set under a non-energized state. In this case, contact points 2, 5 and 8 are switched toward (b) and coils 3, 6 and 9 are short-circuited at each both ends by the contact points 2-8. When an objective lens tries to move in the focus direction or the tracking direction or a pickup tries to move in the disk radius direction owing to vibration, etc., the counter electromotive force is produced at the coils 3-9 to prevent the shift of the objective lens or the pickup. Thus a collision is avoided between the pickup and a disk and therefore the injuries of these pickup and disk are prevented.
