[Detailed description of the invention] Ultrasonic vibrators used in ultrasonic welding, ultrasonic
plastic working, etc., the humidity during loading is high and it works at night to produce a
resonant stripe, so that the vibrator and the vibration in a short time There is a sense 11 I to lose
the oscillator that excites the child. In general, a piezoelectric element is attached to the outer
surface of a metal vibrator (such as a horn) of an ultrasonic transducer for eO, and a part of
ultrasonic waves is converted to electric quantity by this V) piezoelectric element to generate O
and IIO. By supplying a voltage to the tracking circuit unit that controls the frequency of the
oscillator, the vibrator is always kept in a constant resonance state, but the piezoelectric element
has not only poor adhesion strength to the metal vibrator but also a thermal expansion difference
Since the solution is easily peeled off by the following method, the solution is a solution to the
defect in a part of the solution, and the following description will be made with reference to FIG.

because the company used to increase the company's ability to obtain powerful ultrasound. In
the above embodiment, a single piezoelectric element is used as a piezoelectric element for
detecting a voltage which is sandwiched between electrostrictive vibration elements or a hall I or
a second metal vibration member biased. In this case, the surface of the piezoelectric element O
positive electrode end is electrically insulated from the metal vibrator in the negative 4 of the
electrostrictive vibration element and in the contact with the negative 4). Further, according to
the present invention a metal vibrator and an electrostrictive vibrator element are described in
the example using a #s moving element as an example, and a metal vibrator is self-assembled
with a magnetostrictive vibrator element which is elastic from 7 efts. The idea is to apply the
present invention to l1ill I child as well, 1 to 0 or more ebb the present proposal is a metal

formed by bringing the other metal vibrator into contact (1) Since a piezoelectric element for
voltage detection is inserted in the corresponding surface @ and fixed by the screw part # 0, it is
possible that the vibrator falls off from the vibrator during driving (the function is sufficiently
exhibited and the vibrator is Always maintain constant resonance, and most of the voltage
detection piezoelectric elements are metal Therefore, covered with are for the vibrator, as
wearing the durability of the piezoelectric element for voltage detection Wuyi Mel large t!
