Title: Driving equipment for ultrasonic vibrator
Inventor: FUNAKUBO TOMOKI
IPC: H02N2/00
Filed: 1993-10-12
Abstract: PURPOSE:To make it possible to immediately polarize a laminated piezoelectric element if it is depolarized, by providing a means for applying driving voltage to the piezoelectric element and DC power supplying means for polarizing the piezoelectric element. CONSTITUTION:An oscillator forms driving signals of a specified frequency, which are applied to a phase A application terminal through a amplifier and one terminal 5a of a relay switch 5. The driving signals are also applied to a phase B application terminal through a phase shifter and one terminal 6a of a relay switch 6. If a motor is driven for an extended period and a laminated piezoelectric terminal is thus depolarized due to temperature rise, the setting of the relay switch 5 is switched from the terminal 5a to the terminal 5b, and that of the relay switch 6 is switched from the terminal 6a to the terminal 6b. Then DC voltage is gradually applied by a DC power supply 9. If the polarization of the laminated piezoelectric element through the voltage application is completed, the setting of the relay switches 5, 6 is switched from the terminal 5b to the terminal 5a and from the terminal 6b to the terminal 6a, respectively.

Filed: 1989-09-30
Abstract: PURPOSE:To detect with high accuracy the bonding state of a sheet material by a method whereby ultrasonic waves are projected from an ultrasonic sensor to a bonded part of the sheet material bonded to a molding drum, and by judging the bonding condition of the sheet material through measurement of the distance to the surface of the bonded part. CONSTITUTION:An ultrasonic sensor 3 is placed so that an incident wave and a reflecting wave are found along a bonding part 2a of a sheet material 2, and therefore, detecting errors due to the thickness of the material 2 are reduced. The material 2 cut in a predetermined length is bonded to a molding drum 1. The molding drum 1 is rotated at a constant speed in a direction shown by an arrow, and at the same time, ultrasonic waves of 1mmphi or smaller are irradiated to the surface of the bonding part 2a from the sensor 3. Accordingly, the distance to the surface of the bonding part 2a is measured. In determining the bonding state of the material 1, since the incident wave and reflecting wave from the sensor 3 are found along the bonding part 2a at all times, detecting errors due to the thickness of the material 2 can be eliminated, thereby securing highly accurate detection of the bonding state.
