摘要： A surgical operation device comprising an ultrasonic piezoelectric transducer for generating ultrasonic vibrations, an oscillation feedback type oscillator for supplying high-frequency power to the ultrasonic transducer, a vibration transmitter connected to the ultrasonic transducer for transmitting and amplifying mechanical vibrations at an ultrasonic frequency, a suction unit and an irrigator. The ultrasonic transducer includes a bolted Langevin type transducer. The feedback circuit of the oscillation feedback type oscillator includes an oscillation voltage detector, a phase comparator, a low pass filter, a differential amplifier, and a voltage controlled oscillator. Thus, the mechanical resonant frequency can be traced in a wide range of fluctuations of a load on the vibration transmitter during vibration and vibrations can start an appropriate mechanical resonate frequency irrespective of the load status of the vibration transmitter at the start-up.

摘要： A gas concentration measuring instrument using the dependency of the propagation velocity of ultrasonic wave propagating in gas on the gas concentration incorporates a dampproof ultrasonic sensor with a metal or the like deposited by evaporation on the surface of the sealing material. Therefore, this gas concentration measuring instrument is almost not affected by the change of temperature and humidity and can precisely measure gas concentration continuously for a long period of time under high humidity. The ultrasonic sensor is formed fundamentally by an ultrasonic vibrator, a holder and a sealing material. More preferably, this sensor is embedded in a block and sealed with an elastic sealing material and a film of conductive material and/or a nonconductive material is formed on the surface of the sealing material, the elastic sealing material, the vibrating end surface of the ultrasonic sensor and the end surface of the block.
