  • Patent number: 6308389
    Abstract: This invention relates to a method of manufacturing an ultrasonic transducer. First, a plurality of printed boards in each of which a plurality of leads are formed in a line are stacked. The end portions of the leads protrude from each printed board. These lead end portions are inserted into a plurality of lead holes of an alignment jig. The plurality of printed boards are buried in the back surface of this alignment jig, and a backing layer is formed by resin molding. After that, the alignment jig is removed from the surface of the backing layer, and the surface of the backing layer is flattened. Since the end portions of the leads are exposed to this flattened surface of the backing layer, discrete electrodes formed on the back surfaces of transducer elements are electrically connected to these lead end portions. The accuracy of lead arrangement is thus improved by the use of the alignment jig. This reduces alignment errors of leads with respect to the discrete electrodes of the transducer elements.

  • Publication number: 20010015007
    Abstract: In detecting a boundary line between areas different in light reflectance, it has so far been impossible to specify the boundary line at a distance shorter than the arrangement pitch of photodetectors (pixels) arranged in the camera. In the present invention, luminance variations near the boundary line between areas different in light reflectance are derivated. Further, in unit blocks G corresponding to pixels and arranged in a direction (Y direction) in which the boundary line extends, derivated values of luminance for each row of unit blocks are added and then a variation curve of the added values of derivated luminance values in unit block rows is drawn to specify a peak position thereof and also specify the position of the boundary line X0. Thus, it is possible to specify the position of the boundary line with a high accuracy at a distance shorter than the unit block pitch.

  • Patent number: 6105241
    Abstract: A universal fixture has an alignment surface which temporarily holds a heat sink for installation of a plurality of electrical devices on its working surfaces. The fixture rotates about an axis to place an alignment surface in a first or second mounting position corresponding to a generally vertical orientation of the alignment surface. This corresponds to a horizontal position of the opposite first and second sides of the heat sink temporarily mounted thereon. Double rows of openings in the rotatable alignment member are universal in the sense they are configured to accept connection pins of the common packages to be clamped against the opposite sides of the heat sink. This permits one fixture to accommodate a variety of devices and arrangements. A unique standoff device supports smaller packages above the alignment surface to permit clamping across larger and smaller electrical devices without the necessity of attempting to manipulate and hold the devices by hand during the clamping operation.
