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.

Abstract: With the aim of suppressing power consumption and reducing circuit size, a positive FET is turned on in accordance with a positive pulse signal and turned off when a return voltage rises up to a positive threshold. An active ground clamp circuit causes the output line to return to the ground voltage after the elapse of a predetermined period of time. A negative FET is turned on in accordance with a negative pulse signal and turned off when the return voltage falls down to a negative threshold. The active ground clamp circuit causes the output line to return to the ground voltage after the elapse of a predetermined period of time.

Abstract: Components of an ultrasonic sensor are contained in a cylindrical casing having an end wall closing one end of the casing. A vibrator such as a piezoelectric element is disposed in the casing in contact with the end wall. An integrated circuit chip that includes a signal generator, a filter device and a temperature sensor is contained in the casing. Vibrations generated in the vibrator are transferred to the end wall that transmits ultrasonic waves. Ultrasonic waves received by the end wall are converted into electrical signals in the vibrator. Frequency of the transmitting signals and a frequency region of the signals to be received are controlled according to the ambient temperature, so that they always coincide with a resonant frequency of the end wall which changes according to the ambient temperature. Thus, high transmitting/receiving efficiency is always realized, irrespective of the ambient temperature.
