Abstract: A semiconductor device includes a trim storage and an encoder. The trim storage stores trim values. The encoder determines a magnitude of a supply voltage, determines a magnitude of a handle voltage, determines a source-to-handle voltage of a first transistor, and determines a source-to-handle voltage of a second transistor. Further, the encoder determines a target number of selectable first transistor units comprising the first transistor to select for the first transistor. Based on a trim value from the trim storage, the source-to-handle voltage of the first transistor and the source-to-handle voltage of the second transistor, the encoder determines a target number of selectable second transistor units comprising the second transistor to select for the second transistor. The encoder asserts control signals to select the target number of selectable first transistor units and the target number of selectable second transistor units.

Abstract: A vibration transmitting member transmits ultrasonic vibration generated by an ultrasonic transducer from a proximal side toward a distal side. The vibration transmitting member includes a connection connected to the ultrasonic transducer. When a reference vibration node, which is located most proximally among vibration nodes occurring on the distal side relative to the connection, is defined, while the vibration transmitting member vibrates at a resonance frequency in a predetermined frequency range, a cross-sectional area decreasing part is provided between the connection and the reference vibration node. In the cross-sectional area decreasing part, a cross-sectional area perpendicular to a longitudinal direction gradually decreases from the distal side toward the proximal side.

Abstract: A transmission circuit for ultrasonic diagnosis includes a delay processing circuit that delays a transmission signal pattern and an operational circuit that calculates a delay time. A transmission timing for supplying the transmission signal pattern to a plurality of piezo electric elements corresponding to a plurality of channels is approximated by a multi-dimensional polynomial with locations of the plurality of piezo electric elements being variables so that the transmission timing becomes linear or arc-like. Coefficients in the multi-dimensional polynomial are supplied to the transmission circuit for ultrasonic diagnosis. The delay time in the delay processing circuit is determined by a first coefficient. The operational circuit calculates the delay time based on a second coefficient. The transmission signal pattern is supplied to the plurality of piezo electric elements at a transmission timing including the delay time according to the first coefficient and the delay time according to the second coefficient.

Abstract: An ultrasound diagnostic apparatus according to a present embodiment includes driving pulse generating circuitries and a transmission control circuitry. The transmission control circuitry turns on a switching element of respective driving pulse generating circuitries of the driving pulse generating circuitries to be grounded, and thereby controls so as to make an output impedance of the respective driving pulse generating circuitries become a low impedance. The transmission control circuitry turns off the switching element of the respective driving pulse generating circuitries, and thereby controls so as to make the output impedance become a high impedance by means of a resistance value of the resistance. The transmission control circuitry controls so as to make the output impedance of the respective driving pulse generating circuitries become a lower impedance during a transmission period in which the ultrasound is transmitted than during a reception period in which a reflected wave of the ultrasound is received.
