  • Patent number: 6979650
    Abstract: In order to reduce micro scratches which tend to occur during chemical-mechanical polishing, a polishing slurry is diluted with deionized water immediately before it is supplied in a gap between a polishing pad and the surface of a wafer to be polished. By diluting the polishing slurry with deionized water to increase its volume, the concentration of coagulated particles contained in the polishing slurry can be lowered. For a mixture ratio of the polishing slurry and deionized water, about 1 (polishing slurry): 1–1.2 (deionized water) is used, and the concentration of silica contained in the diluted polishing slurry is adjusted to about 3–9 weight %, preferably about 4–8 weight %, and more preferably about 8 weight %.

  • Patent number: 6020681
    Abstract: A color cathode-ray tube, and a method for manufacturing this color cathode-ray tube capable of reducing light/dark line patterns produced while the color cathode-ray tube is operated. Exposing light which has passed through a correction lens made of a continuous lens and a discontinuous lens is irradiated onto a photosensitive film of an inner surface of a face panel of the color cathode-ray tube via a shadow mask so as to expose this photosensitive film, and then while using the exposed photosensitive film as a mask, fluorescent dot patterns are formed on a surface of the face panel. The correction lens having a discontinuous plane owns a plurality of light incident planes, a light projection plane for projecting the light entered into the light incident planes outside this light projection plane, and a plurality of level difference planes arranged between the light incident planes located adjacent to each other.

  • Patent number: 5166824
    Abstract: In a rear projection screen, a plurality of convex lenses of the prescribed configuration are made of photoresist and formed and arranged on a surface or surfaces of a substrate in the prescribed pattern. In case that the convex lenses are formed in the shapes of ellipsoid, the longer radial direction of the ellipsoid is made to coincide with the horizontal direction and shapes of the lenses are changed gradually from the center of the screen to the extremity thereof. Bottom surfaces of non-lens boundary grooves between adjacent convex lenses are made rougher than the convex lens surfaces. A screen manufacturing method comprises the steps of applying photoresist onto a surface or surfaces of a substrate, exposing a patttern of boundary grooves onto the photoresist by photolithography, forming the boundary grooves by etching, and heating and melting the photoresist which is formed with the boundary grooves so as to form a plurality of convex lenses having the prescribed configuration.

  • Patent number: 4786163
    Abstract: An auto-keratometer attached to an operating microscope to measure the refraction and astigmatic condition of the cornea comprises a cornea irradiating light source section disposed below the operating microscope, and switching means for selectively switching the light source section between an irradiating position on the optical axis and a retracted position. When it is desired to measure the corneal condition, the light source section is set at the irradiating position below the operating microscope, so that the light from the light source section reflected by the cornea travels through a beam splitter and is detected by a detector, whereby the refraction or astigmatic condition of the cornea is measured. If the light source section is found interfering with the operation, the light source section is set at the retracted position by rotating it through 180 degrees, whereby the working region below the microscope is widened to facilitate the operator's surgical operation on the cornea.

  • Patent number: 4662801
    Abstract: This invention relates to a tool for use in carrying out a cutting process, and more particularly to a cutting tool formed so that it can be sued to cut an iron material of a high hardness and thereby obtain a mirror-polished surface thereon, the cutting tool being characterized in that it is formed by attaching a monocrystal of boron nitride to the tip thereof so that predetermined surface and orientation of the crystal are set suitably. To be concrete, the present invention is directed to a cutting tool in which monocrystalline boron nitride is used for a tip which forms a blade of the cutting tool, (111) surface of this boron nitride being used as a relief surface of the blade, <211> direction being used as a cutting direction; or a cutting tool of the same material, in which (100) surface of the boron nitride is used as a relief surface of the blade, <110> direction being used as a cutting direction.

  • Patent number: 4504940
    Abstract: A stylus suitable for use with a video disc player of a type in which signals representing changes in electrostatic capacity with respect to a video disc are detected, including a scanning surface brought into contact with the video disc for scanning same, a plurality of inclined surfaces, and a plurality of ridges formed by the inclined surfaces. At least one of several meeting points of the plurality of ridges located in a direction in which scanning is performed is chamfered to render the point blunt. A stylus of the aforesaid shape is produced by a grinding method consisting in using a grinder pan composed of a plate of soft resin having a coat of hard material applied to its surface and forcing a forward end of a stylus against such grinding pan.
