Abstract: A supersonic transducer including means for detecting its vibrating speed and for changing the frequency of the energizing current in response thereto. This invention utilizes the property that when an electrostrictive vibrator is vibrated resonantly, its dynamic admittance varies depending upon the difference in its stress distribution. The electrostrictive vibrator is divided into portions of large and small stresses to cancel the applied brake currents. Simultaneously, a signal is derived that is proportional to the difference of the dynamic currents so as to provide an effective energization by detecting the resonant frequency of the vibrator in order to automatically adjust the applied frequency of the supersonic transducer.

Abstract: A dielectric elastomer vibration system includes a dielectric elastomer vibrator with a dielectric elastomer layer and a pair of electrode layers, and a power supply device producing a potential difference across the electrode layers. The vibrator exhibits various modes or regions of relationship between potential difference and deformation induced by the potential difference: a high-response region in which a relatively large deformation is induced; a low-response region of lower-potential difference in which a relatively small deformation is induced; and a low-response region of higher-potential difference in which a relatively small deformation is induced or in which a break point of the dielectric elastomer layer is included. The power supply device produces the potential difference by applying across the electrode layers a vibration signal voltage, which is generated by combining an AC voltage with a bias DC voltage corresponding to a potential difference falling in the high-response region.

Abstract: A method for flating the phase characteristic of a differential detection signal in one higher and lower regions thereof relative to its resonance frequency by controlling a differential characteristic. A searching, over a range, which is wider than the width of the flat region, is accomplished prior to phase characteristic being effected thereby discriminating a fundamental resonance frequency. After this discrimination of the fundamental resonance frequency, automatic tracking is effected under stable corrected phase characteristics for the fundamental resonant frequency whereby high electro-mechanical conversion efficiency can be maintained.
