  • Ultrasonic transducer
    Patent number: 5200666
    Abstract: In an ultrasonic transducer for the transmission of ultrasonic energy to a liquid which has ultrasonic generators coupled to opposite ends of rod-like resonators which both operate at the same frequency to transmit ultrasonic vibration to the resonator to be emitted therefrom, no radiation is emitted from the ends occupied by the generators so that all radiation is emitted from the resonator in a desired radial fashion.
