Abstract: A device for driving a piezoelectric vibrator is comprised of an AC power supply for supplying electric power to a piezoelectric vibrator for vibration thereof, a detecting device for detecting current supplied to the piezoelectric vibrator, and a driving circuit interposed between the AC power supply and the piezoelectric vibrator so as to decrease the electric power being supplied to the piezoelectric vibrator as the current flowing therethrough increases. This structure brings a decrease in electric power being supplied to the piezoelectric vibrator when current flowing therethrough is increased during resonance of the piezoelectric vibrator, thereby enabling the restriction or regulation of the expansion and contraction of the piezoelectric vibrator while maintaining resonance thereof.

Abstract: An amplitude control unit for an ultrasonic machine comprises a load detector for detecting the load applied to the tip of a tool during ultrasonic machining on the work, a load/amplitude conversion circuit for converting the load output detected by the load detector into an amplitude conversion value appropriate for the load at the tip of the tool, an amplitude addition circuit for receiving the amplitude conversion value generated by the load/amplitude conversion circuit and for adding it to a predetermined amplitude value at no load. The vibration of the piezoelectric transducer is changed to correspond to the load applied to the work by sending the new amplitude value generated by the amplitude addition circuit to the high frequency oscillator.

Abstract: There is disclosed a constant amplitude controller with feedback control for a vibratory feeder apparatus wherein a controlled rectifier is used to rectify the A.C. line voltage applied to the feeder solenoid and to control the voltage to the feeder solenoid. Triggering of the controlled rectifier is accomplished by a bias control signal which is composed of an A.C. phase shift voltage superpositioned by a variable D.C. bias voltage. Mechanical coupling is provided between the solenoid and a transducer which provides feedback to control logic circuitry. In the control logic circuitry, the signal received from the transducer is compared with a signal received from an operator adjusted potentiometer. In this manner, the desired amplitude of the vibrator apparatus is compared with the actual amplitude of the vibrator apparatus and, if there is a discrepancy, the control logic circuitry modifies the amount of control voltage being transferred by the controlled rectifier.

Abstract: A wide bandwidth, ultrasonic frequency transducer drive circuit incorporates a first unidirectional signal path from a source of drive signals to the transducer. A second unidirectional signal path from the source of drive signals couples signals away from the transducer. A circuit resonant with the transducer causes a relatively high signal voltage to be developed across this transducer.

Abstract: A polarizing DC voltage is generated at the capacitance of an ultrasonic transducer and then short circuited by a parallelly arranged electronic switch controlled by the command signal frequency to be radiated. A direct current stored in an inductance during the shorting phase is supplied by way of a decoupling diode to the electrodes to the electrostatic transducer upon opening of the switch thereby generating a polarizing DC voltage for the transducer which is regenerated periodically. For achieving additional energy recuperation, a booster capacitor is disposed in series with the inductance and a booster diode is connected in parallel with the booster capacitor and a portion of the inductance.
