  • Patent number: 8293330
    Abstract: While one side of a lens L is held by a suction-holding member 17 and the suction-holding member 17 is moved by the moving mechanism, a coating process, a drying process, and a curing process are sequentially performed in respective receptacles disposed independently of each other. A suction force applied to the lens L by the suction-holding member 17 is controlled by a control section 22 in accordance with each of the receptacles in which the suction-holding member 17 is positioned.
    Type: Grant
    Filed: December 22, 2006
    Date of Patent: October 23, 2012
    Assignee: Hoya Corporation
    Inventors: Kenichi Shinde, Katsuaki Uchida, Tomohiro Ogawa, Tetsuhisa Nakamura, Hideki Hasegawa

  • Patent number: 6046256
    Abstract: A water-based dispersion composition obtained by partially or wholly neutralizing a mixture of a modified epoxy resin (A) as an emulsifying resin and an aromatic epoxy resin (B) having a number average molecular weight of 1,000 to 30,000 as a resin to be emulsified, with ammonia and/or an amine, the modified epoxy resin (A) being a modified epoxy resin obtained by reacting an aromatic epoxy resin (a1) having an epoxy equivalent of 2,000 to 20,000 with an acrylic resin (a2) having an acid value of 50 to 450 and containing acrylic acid and/or methacrylic acid, the water-based dispersion composition is applied to an internal surface of a metal can particularly required to have high processability and corrosion resistance by coating it directly on a metal material or coating it on an undercoating, baking it and drying it.

  • Patent number: 5008108
    Abstract: A method for utilizing a purified exocellular polysaccharide, Zooglan, produced by Zoogloea ramigera, as a viscosity modifier, gellant, drag reducing agent, dispersant, flocculant, or emulsifying agent, wherein the properties of the polymer are dependent on, and can therefore be controlled by varying, the pH, the concentration of polymer, the ionic strength of the solution, and the processing parameters such as mechanical shear.The overall conformation of Zooglan, which is responsible for its functional properties, can be manipulated with pH and/or ionic strength of the solution. For example, the intrinsic viscosity of Zooglan (estimated m.w.=2.times.10.sup.7) can vary from 16 to 170 dl/g in aqueous solution as a function of pH between 2-9 and salt concentration between 0 and 1M KCl. Zooglan is a polyelectrolyte above pH 2. The Zooglan chain is relatively stiff, with a stiffness parameter of 0.02. Zooglan solutions at a concentration above 0.
