ULTRASONIC TRANSMITTER-RECEIVER

摘要

PURPOSE:To prevent the release of an internal piezoelectric vibrator from a shoe (or a wedge) even when an ultrasonic transmitter-receiver receives a heat shock from an object to be measured. CONSTITUTION:An ultrasonic transmitter-receiver is constituted by bonding a piezoelectric vibrator to a shoe 4 and transmits and receives ultrasonic waves in the direction oblique with respect to a mounting surface. A synthetic material having many grooves 8, 9 provided thereto at a predetermined interval is provided to the entire area of the surface bonded to the piezoelectric vibrator 3 of the shone 4.
