摘要： A compact or miniaturized well-shielded double superheterodyne tuner is provided, wherein an input circuit portion, a first mixing portion, a first intermediate frequency bandpass filter, a second mixing portion and an output circuit portion are mounted in separated casings. The first mixing portion and the second mixing portion are provided on printed boards and each mounted on a bottom plate of the casing. The casings containing the first and second mixing portion are arranged in a manner such that grounded surfaces of the printed boards contained in the casings are arranged face to face. The casing containing the bandpass filter is contacted adjacently to a common face of the face to face casings. Each of the casings containing the input and output circuit portions is located adjacently to each of faces common to the face to face casings and the filter containing casing. Some structual improvements are also provided for simplifying the manufacture and adjustment of the tuner.

摘要： An ultrasonic probe which scans an ultrasonic beam in a sector area by a mechanical drive is disclosed. The ultrasonic probe essentially has a driving motor, a rotary shaft rotatably supported in a direction perpendicular to the direction of the driving shaft of the driving motor, a rotor shaft rotatably supported in a direction parallel to the direction of the rotary shaft, a rotor mounted on the rotor shaft for carrying ultrasonic transducers, screw gears for transmitting rotation of the motor to the rotary shaft, and a transmitting device for transmitting rotation of the rotary shaft to the rotor.
