摘要： Provided is a diagnostic ultrasound system producing an image whose brightness is enhanced by a contrast medium by implementing contrast echography based on intravenous injection. A diagnostic ultrasound system comprises a probe for converting an electrical driving signal into a corresponding transmission ultrasound wave and converting an echoed ultrasound wave into a corresponding electrical echo signal. The system still comprises a unit for transmitting the transmission ultrasonic wave to a subject by providing the probe the electrical driving signal substantially consisting of a fundamental component of a given driving frequency. The non-fundamental component is typically a second harmonic. A non-fundamental component of the driving frequency is intentionally lowered in power relative to the fundamental component by a suppressing element in the transmitting unit. The system comprises a unit for receiving the echo signal from the probe and processing the echo signal into a display image data reflecting both the fundamental and non-fundamental components and a unit for displaying the display image data.

An earth electrode is provided at the other side of the transducer elements. Each of a plurality of signal conductive members is connected to a corresponding signal electrode. An earth conductive member is connected to the earth electrode.

摘要： An ultrasound diagnosis apparatus that can acquire ultrasound image data having excellent spatial resolution and contrast resolution by electrically controlling focusing points of transmission/reception waves so as to form transmitting beams and receiving beams having substantially uniform thin beam width along an elevation direction. Ultrasounds emitted from a prescribed number of transducers are focused at a hypothetical point sound source. Wave-fronts reflect at a plurality of observing points. Ultrasounds reflected at the observing points are received through a prescribed number of transducers generating a plurality of channels of receiving signals, which are focused by performing phase compensation and summation so that the observing point becomes a reception focusing point. The receiving signals are focused to correct transmitting delays due to propagation distances between the transmitting focusing point and the observing points.

摘要： Plural thin plate projecting portions are integrally and projectingly provided on an outer peripheral portion of a side plate member of a bobbin. Each of the thin plate projecting portions comprises a circumferential rib, a slit portion and a reinforcement rib. The circumferential rib is provided on an outer peripheral face of the thin plate projecting portion of the bobbin and then a gap is formed between a claw-shaped magnetic pole of a rotor core and the thin plate projecting portion. A varnish material etc. is caused to adhere to and harden in this gap. By filling a root portion of the claw-shape magnetic pole of the rotor core with varnish material, the resonance vibration in the rotor core can be restrained. As a result, an alternating current generator for use in a vehicle having the small magnetic noise can be obtained.

摘要： In an ultrasonic diagnostic apparatus in which ultrasonic echo beams is focused three-dimensionally, a probe employs plural transducers arranged in two directions, lateral and azimuth directions. The transducers arranged in each azimuth direction are connected to a transmitting-receiving channel in a transmitting-receiving portion via a switch circuit. The switch circuit operates on the control of a switching controller and can connect a transducer selected by the controller in the azimuth direction to the transmitting-receiving channel. Output signals from the transmitting-receiving portion are supplied to a signal processing portion, in which beam forming for three-dimension echo beams is carried out by using a beam former. Thus, transducers arranged on each line in the lateral direction can be driven simultaneously, resulting in a more compact circuit and a reduced number of transmitting and receiving for better real-time processing. Further, the beam former is devided into two stage, one for the lateral direction and the other for the azimuth direction. This combination of two beam formers lead to adjustable focuses in the both direction in addition to a reduced memory capacity in the signal processing.
