  • Ultrasonic probe
    Publication number: 20050113700
    Abstract: The present invention provides an ultrasonic probe, which is soft for the subject, and which has an ultrasonic transceiver unit and an enclosure for housing the unit. The integrated enclosure includes a first partial enclosure made of hard plastics and having an opening at one end, and a second partial enclosure molded together with the first partial enclosure so as to cover the opening to expand beyond the end, the transmission/reception surface of the ultrasonic transceiver unit being in contact therewith from inside.

  • Thickness detecting caliper for sheet material having elastic arms with printed coils
    Patent number: 6175235
    Abstract: A pair of elastic strips are provided in order to hold sheet material to be measured in thickness. Each of the elastic strips includes of one or more elastic films. Ends of the elastic strips are supported by support portions, and the other ends of the elastic strips are provided with respective coils, opposed to push each other, and kept in contact with each other. When the sheet material is held between support portions, the inductances of the coils are changed and the thickness of the sheet material is detected as an electric signal representative of the changed inductance.

  • Image scanner apparatus with scanning function
    Patent number: 4760463
    Abstract: An image scanning section has an optical system for scanning an original in a two-dimensional manner, and a photoelectric converter for converting an optical image obtained by the optical system into an electrical signal. A binary coding section performs simple binary coding of the electrical signal supplied from the photoelectric converter in such a manner as not to accompany pseudo-gray scale coding, and performs pseudo-gray scale binary coding of the electrical signal supplied from the photoelectric converter in such a manner as to accompany pseudo-gray scale coding. An area designating section designates an area on the original. A scanning mode designating section designates image scanning modes within and outside an area designated by the area designating section and has at least a first scanning mode designating section which does not accompany pseudo-gray scale coding and a second scanning mode designating section which accompanies pseudo-gray scale coding.
