  • Publication number: 20110239834
    Abstract: An apparatus for processing a hole with a rounded edge includes a punch having a rounded shape formed at a base portion of a cutting tip, and a die supporting a peripheral edge of a pierced hole formed through piercing by the cutting tip of the punch with a pressure receiving surface perpendicular to a punch axis. By driving the punch to make a single stroke motion, a hole is pierced in a work piece by the cutting tip of the punch to form the pierced hole and the rounded shape of the cutting tip is transferred onto a ridge portion on the side of a design surface of the pierced hole. This permits efficient processing of holes with a rounded edge. In addition, by supporting the peripheral edge of the pierced hole with the pressure receiving surface, a uniform and highly accurate rounded shape can be formed on the ridge portion of the pierced hole.

  • Patent number: 6124955
    Abstract: A light-beam scanning apparatus includes at least two holograms with an optical path length difference .DELTA..PHI. along a scanning beam light flux. The path length is measured from a light source to a scanning surface in the first hologram, and is represented by .DELTA..PHI.<C(.lambda..sup.2 /D.lambda.) where C is a constant less than 0.5. The path length is related per the above equation to a wavelength, .lambda., at the center of the light source, and a wavelength displacement .DELTA..lambda. measured from the wavelength .lambda. at the center of the light source.

  • Patent number: 5982342
    Abstract: A parallax image generator establishes a plurality of projected regions around a display in predetermined intervals and generates a plurality of parallax images having different parallaxes due to being seen from respective points of view. In addition, pixels of the plurality of parallax images occupying the same position are gathered together in a pixel block, and are mapped to rendering memory corresponding to the display. A parallax image display unit displays mapped images in the rendering memory, projects the light from a pixel toward the projected region corresponding to each parallax image per pixel of the plurality of parallax images in each pixel block, and makes a 3-D image observed by positioning both eyes of an observer in adjacent projected regions and projecting the parallax images.

  • Patent number: 5940195
    Abstract: A high-resolution light-beam scanning apparatus utilizing only mass-producible holograms instead of utilizing auxiliary optical systems such as optical lenses or a mirror having curvature, and capable of compensating for disadvantages including scanning beam thickening and variation, failure of a rotatable hologram to rotate at a constant velocity, displacement of a scanning beam position in the scanning direction and the cross scanning direction due to a mode hop of a wavelength of a semiconductor laser, and deviation of a base of rotatable hologram from a parallel state. These disadvantages are detrimental to efforts for increasing the resolution of a hologram scanner and lowering the cost thereof. The light beam scanning apparatus includes at least two holograms with an optical path length difference .DELTA..PHI. along a scanning beam light flux. The path length is measured from a light source to a scanning surface in the first hologram, and is represented by .DELTA..PHI.<C(.lambda..sup.2 /D.lambda.

  • Patent number: 5872590
    Abstract: A position of an observer in a stereoscopic observing region is detected by a position detecting unit. A right-eye image and a left-eye image which are seen from the detecting position are formed by an image forming unit and displayed on a display. By setting an aperture position of a projection optical system, the right-eye image is projected to the right-eye position of the observer and the left-eye image is projected to the left-eye position, thereby allowing a stereoscopic image to be observed. Further, an aperture is set so as to project the right-eye image or left-eye image to a position different from the detecting position of the observer, thereby allowing a same image to be seen to both eyes of another observer and allowing a two-dimensional image to be observed.
