  • Patent number: 4391282
    Abstract: A coeliac cavity ultrasonic diagnosis apparatus which includes an ultrasonic transducer or scanner portion adapted to be inserted into a coeliac cavity to effect a sector scan of an ultrasonic beam to produce an ultrasonic image of internal tissues and in which the ultrasonic oscillator on the one hand and an ultrasonic reflecting mirror and rotary disc on the other hand are relatively rotated so as to effect the sector scan of the ultrasonic beam and the rotary angle of the rotary disc is detected so as to obtain a deflecting angle of the ultrasonic beam and a display on a cathode ray tube of a precise ultrasonic picture image.

  • Patent number: 4375818
    Abstract: An ultrasonic diagnosis system includes an ultrasonic wave transmitting and receiving transducer which is rockably disposed within the distal end of a portion of an endoscope which is adapted to be inserted into a coeliac cavity. The transducer emits ultrasonic wave from within the coeliac cavity and directs it toward internal tissues of a physical body, thereby enabling an ultrasonic tomographic image to be obtained. The endoscope also includes an observation optical system which permits the location of the ultrasonic transducer within the coeliac cavity to be visually recognized.

  • Patent number: 4242541
    Abstract: A composite type acoustic transducer of a flat drive type electrodynamic transducer and a piezoelectric type transducer. A diaphragm has a membrane of any suitable shape made of high molecular piezoelectric material such as polyvinylidene fluoride, an electrode layer applied on one surface of a membrane, and a coil like conductor applied on the other surface of the membrane. A supporting member supports the diaphragm along its edge. A permanent magnet device produces a magentic field extending in parallel to a plane of the diaphragm and perpendicular to the coil like conductor.
