Filed: 1994-12-07
Abstract: PURPOSE:To finely finish work surface roughness of a work object by directly connecting a series circuit of a resistor and a light emitting element in parallel to a discharge clearance as a discharge condition detecting circuit. CONSTITUTION:When only a discharge condition detecting circuit is connected at finishing work time by a mechanical opening-closing switch 48, only a seried circuit of a resistor 41C and a light emitting element 41A is connected in parallel to a discharge clearance. Thereby, floating capacitance around the discharge clearance or by a circuit network at least around the discharge clearance is put in the most reduced condition. As a result of this, discharge having a high peak current value by the floating capacitance by the circuit network around the discharge clearance or discharge energy per single discharge does not become larger than a prescribed value. Thereby, a work surface is not roughened.

Title: Control unit for automatic transmission for vehicle
Inventor: SAKAKIBARA SHIRO
IPC: F16H61/18
Filed: 1988-12-29
Abstract: PURPOSE:To prevent the life lowering of a non-stage transmission with unnecessary change gear eliminated by stopping the change gear of the non-stage change gear device when a travel condition is in a very-slow or a slow speed travel region and a torque ratio is in an under-drive side. CONSTITUTION:In an electronic control unit 120, travel conditions of a vehicle are classified into very-slow speed, slow speed, and normal travel regions based on the signal of a speed sensor 167. The change gear of a non-stage transmission 30 is prevented in the very-slow speed travel region where the number of revolution of a primary or secondary pulley 31 or 32 can not be correctly detected with sensors 165 and 166. And the change gear of a non-stage change gear device 30 is stopped too when a torque ratio is in an under drive side in the slow speed travel region. Consequently since the slow speed travel region is surely passed when a vehicle is stopped, the vehicle can be stopped with the device 30 surely made to the condition of the maximum torque ratio, and restarting can be made with the maximum torque ratio. Thus unnecessary change gear is eliminated and life lowering can be prevented.
