摘要： An ultrasonic vibration application tool equipped with a Langevin type ultrasonic vibrator which is suitably employable for ultrasonic processing devices and which efficiently generates ultrasonic vibration includes: a cylindrical housing having a contact face on a lower or bottom part of an inner surface thereof, and a lower screw part of an outer surface thereof; a bolted Langevin type ultrasonic vibrator comprising a front mass, a rear mass and a polarized piezoelectric element arranged between both masses, in which the front mass comprises a cylindrical tool-holder and a disc-shaped bulging part provided with a contact face for fitting to the contact face of the housing; and a ring-shaped counterweight having an upper screw part on an inner peripheral surface which is screwed with the screw part of the housing.

摘要： A novel mode of ultrasonic oscillation is generated in a Langevin ultrasonic transducer comprising a metal block, a metal block provided with a supporting means protruding in a ring shape on its side surface, and polarized piezoelectric elements fixed between these metal blocks, by connecting the ultrasonic transducer to a base via the supporting means, whereby supporting the ultrasonic transducer on the base in a restrained state, and applying to the piezoelectric elements a voltage having such frequency that the ultrasonic transducer generates an ultrasonic oscillation with back-and-forth motion in a direction perpendicular to plane surfaces of the piezoelectric elements which has no oscillation node within the ultrasonic transducer; this novel ultrasonic oscillation mode is utilized for performing ultrasonic machining methods as well as for ultrasonic transmission method.
