摘要： In a pulse power source for applying a pulse voltage to a capacitive load; a series resonance circuit capable of generating transient oscillation is formed of the capacitive load adapted to be applied with the pulse voltage, an inductance for generating transient oscillation and a power source capacitor; the capacitive load is charged from the power source capacitor by first closing one of two switch elements provided in the midway of the resonance circuit, that is, a load charging switch element to make the voltage across said capacitive load rise up to about twice the voltage across the power source capacitor after a period equal to about 1/2 of a transient oscillation period of said series resonance circuit, to form a rising edge of the desired pulse voltage; then reversely, the power source capacitor is charged from the capacitive load by closing the other switch element, that is, a charge recovering switch element after first said one switch element has been closed to make the voltage across said capacitive load fall down, to form a falling edge of the desired pulse voltage; and further a residual charge on said capacitive load is discharged by closing still another switch element provided in parallel to said capacitive load, to improve the falling edge of the desired pulse voltage; whereby a steep pulse voltage can be applied to said capacitive load with a low power loss.

An electrodeless unit for transmitting electric power by way of high-frequency electromagnetic induction and a unit for transmitting signals by way of optical transmission or high-frequency electromagnetic induction are installed in either a reduction gear that is coupled to the shaft of a motor for actuating each of the shafts of the robot or a direct-drive motor. Electric power or signal wires are drawn through a groove or hollow defined in an output shaft of the reduction gear or the direct-drive motor. Information produced ahead of the output shaft is fed back over signal wires that are drawn through the groove or hollow defined in the output shaft.
