Title: Manufacture of wire electrode for electric discharge machining
Inventor: TOMINAGA HARUO
IPC: C23C2/04
Filed: 1988-03-26
Abstract: PURPOSE:To reduce manufacturing cost, and to improve performance by purify ing the surface of a steel wire, and immersing it into fused copper to form a coated layer of copper, and then immersing it into fused zinc or fused copper-zinc alloy to form a coated layer thereof, and further subjecting it to wire drawing. CONSTITUTION:A fine steel wire 1 is subjected to purifying treatment, and is immersed into fused copper 4 for coating copper, and after the temperature thereof has dropped, it is immersed into fused zinc or fused copper-zinc alloy 5 to form a coated layer thereof, and then is subjected to wire drawing. Accordingly, since there is no wire drawing process for reducing a large diameter to a fine diameter, large- and intermediate-size wire drawing machines can be eliminated, and the annealing process for removing work-hardening strain can be also eliminated. Further, an electrogalvanizing process as before becomes unnecessary, and a copper-zinc alloy layer is formed by a fused immersion plating, and at the same time it forms an alloy with the copper being ground metal, so that the heat treatment for the formation of alloy also becomes unnecessary. Thus, since the wire electrodes can be manufactured by a simple process, the manufacturing cost can be remarkably reduced, and the selection width of material such as the use of a high-strength steel wire can be extended, and the performance of the wire electrodes can be further improved.

Abstract: PURPOSE:To enable automatic clutch control at the time of engine stop and failure in the case of using an engine driven hydraulic pump for automatic clutch control by providing a manual-operated oil pressure generating device for feeding operating oil manually and a manual-operated switching valve for discharging operating oil manually in parallel with each other. CONSTITUTION:When a clutch pedal is pushed in against the spring 62 of a manual-operated oil pressure generating device, negative pressure is generated in a pressure chamber 54, so that a check valve 56 is closed, whereas a check valve 58 is opened to suck operating oil in a drain tank 34 up into the pressure chamber 54. When a manual-operated switching valve 47 connected to the pressure chamber 24 of a hydraulic cylinder 10 is opened manually, operating oil in the cylinder 10 can be discharged. Accordingly, in case it is not possible to open a second solenoid switching valve 40 or a third solenoid switching valve 42 to discharge operating oil in the cylinder 10 for gear-in parking because of the failure of a timer operated at the stop time of an engine 16 and therefore gear-in parking cannot be performed, the operating oil is discharged by a switching valve 47 so as to place an automatic clutch in the connected state to perform gear-in parking.

Title: Forced commutation circuit employing gate turn off thyristor
Inventor: TAKEI HIDETOSHI
IPC: H02M1/06
Filed: 1979-06-14
Abstract: PURPOSE:To protect the thyristor element avoiding the application of the step voltage to the other thyristor while making the circuit smaller employing the gate turn off thyristor in the forced commutation circuit. CONSTITUTION:As soon as the gate turn off thyristor (GTO)SA1 is fired at the time t1, the commutation condenser C starts resonance. As soon as the auxiliary thyristor SA3 is fired at the time t5, the reverse voltage for turning off is applied to the main thyristor S1 as shown by the dotted line of the waveform diagram. In addition, the current transformer CT, for example, detects the current of GOTO SA to be zero and the gate signal for turning off is generated to the thyristor SA1 at the time t2 from the control circuit 6 to lessen the gate signal current for turning off. Thus, as compared with the conventional type, the element can be protected while the commutation circuit is miniaturized.
