Abstract: A vibratory actuator includes a vibration body, a contact body, a base, a holding member, and a flexible substrate. The vibration body includes an elastic body and an electro-mechanical energy conversion element. The contact body is in contact with the elastic body and relatively moves with the vibration body due to vibration of the vibration body. One end of the flexible substrate is arranged along a first surface of the holding member and is folded back with respect to an end portion of the holding member toward a second surface of the holding member on a back side of the first surface, and an other end of the flexible substrate is supported by a portion of the base. The flexible substrate separates from the second surface to form a U-turn portion so that the one end and the other end of the flexible substrate are electrically connected.

Abstract: An ultrasonic apparatus includes an ultrasonic transducer, a transmitting circuit, a receiving circuit, a Q-factor measuring circuit, and a frequency measuring circuit. The ultrasonic transducer is a three-terminal ultrasonic transducer that includes a transmitting electrode, a receiving electrode, and a common electrode. The transmitting circuit outputs a driving signal to the transmitting electrode to cause the ultrasonic transducer to transmit ultrasonic waves. The receiving circuit receives a receive signal from the receiving electrode. The frequency measuring circuit measures a resonant frequency of the ultrasonic transducer from a reverberation signal in the receive signal. The Q-factor measuring circuit measures a Q factor of the ultrasonic transducer from the reverberation signal in the receive signal.

Abstract: According to one embodiment, an ultrasonic probe has a laminated structure of an acoustic matching layer, transducer layer with arrayed transducers, and backing layer. A transmission/reception unit transmits and receives ultrasonic waves to and from an object via the transducers. A control unit controls the transmission/reception unit to synchronize ultrasonic-wave generation by a specific transducer of the transducers with ultrasonic-wave reception by a different transducer. A phase shift detection unit detects a phase shift between an output signal from the transmission/reception unit and a reference signal, the output signal corresponding to synchronization between the ultrasonic-wave generation and the ultrasonic-wave reception.
