Abstract: PROBLEM TO BE SOLVED: To provide an electric discharge machining system showing generally constant machining performance. SOLUTION: The electric discharge machining system comprises a conductor plate 19 provided in contact with a holder 3 for machined material; plural first conductive cables (16a1-16a4, 17a1-17a4) supplying power from machining power supplying means 13 to a wire electrode 1; plural second conductive cables (16a1-16a4, 17b1-17b4) supplying power from the machining power supplying means 13 to the conductor plate 19; and cable supporting means (15a-15d) supporting the conductive cables at a position generally symmetric with respect to the centroid of the holder 3 for machined material.  Even when the fitting position of machined material 2 on the holder 3 for machined material or the machining position therefor is changed, change in resistance and inductance of the cables involved in power supply from the machining power supplying means 13 to the wire electrode 1 and the machined material 2 can be controlled, and generally constant, good machining performance can be obtained, irrespective of the size of holder 3 for machined material, because the inductance itself is small.

Title: Wiper device
Inventor: OTA SHIGEKI
IPC: B60S1/08
Filed: 2000-12-12
Abstract: PROBLEM TO BE SOLVED: To prevent a damping phenomenon of a retractable wiper device and to reduce a price thereof. SOLUTION: Since a wiper arm 6 approaches a reversing position H1 and a relay plate starts the detection of a position D1, a moor is made to be in an electric damping state, thereby decelerating a wiper arm. Since the starting of the detection of a position D2, the damping force of the motor is released, thereby automatically stopping the wiper arm. For example, the motor is reversed after the expiration of a predetermined time interval since the starting of the detection of the position D2, the wiper arm is reverted from the reserving position H1 and driven to the other reversing position H2, thereby carrying out a wiping out movement.  If reversing before the axial displacement of a rod becomes 0, the motor is made to be in an open state before the reversing position, so that the generation of damping due to an influence of the inertial force on the rapidly reversed wiper arm can be prevented by a simple structure, and the price of the wiper device preventing the generation of damping can be reduced.
