Patent number: 7399498Abstract: A transparent vessel is filled with a mixture solution containing a first photo-curable resin of a low refractive index and a second photo-curable resin of a high refractive index different in curing mechanism. When light at a wavelength capable of curing the first photo-curable resin but incapable of curing the second photo-curable resin is applied to the mixture solution through an optical fiber, the first photo-curable resin can be cured in a state in which the second photo-curable resin is enclosed in the cured first photo-curable resin. Because the refractive index increases according to curing, a self-condensing phenomenon can be generated so that an optical path portion is formed. The optical path portion emits leakage light to its surroundings to thereby form an outer circumferential portion. Then, all uncured resins in the mixture solution are cured.Type: GrantFiled: October 27, 2003Date of Patent: July 15, 2008Assignee: Toyoda Gosei Co., Ltd.Inventors: Yukitoshi Inui, Kuniyoshi Kondo, Tatsuya Yamashita, Akari Kawasaki, Manabu Kagami, Hiroshi Ito, Shin Sato, Hisao Kato

Patent number: 7229520Abstract: A film laminating adhesive is formed by admixing a polyester resin and encapsulated metallic flakes. The metallic flakes are encapsulated with a silane in a hydrolyzed condition modified with a surfactant or dispersion agent. A mounting adhesive is applied to an outside surface of a first clear PET film. A silicone liner is adhered to the outside surface. A second PET film is bonded to another side of the first clear film with the film laminating adhesive containing encapsulated metallic flakes to form the spandrel glass film composite adapted for bonding to a glass surface after removal of the silicone liner.Type: GrantFiled: February 26, 2004Date of Patent: June 12, 2007Assignee: Film Technologies International, Inc.Inventors: Haibin Huang, Verne Joseph R.

Patent number: 7128944Abstract: The invention relates to thermally tempered safety glass comprising an non-abrasive and porous SiO2 layer which is stable during sintering and has a refractive index of between 1.25 and 1.40. The inventive safety glass can be obtained by coating standard soda-lime glass with an aqueous coating solution having a pH value of between 3 and 8 and containing between 0.5 and 5.0 wt. % of [SiOx(OH)y]n particles (0<y<4 and 0<x<2) having a particle size of between 10 and 60 nm, and a surfactant mixture. The coated glass is then dried, thermally hardened at temperatures of at least 600° C. for several minutes, and thermally tempered by a flow of air.Type: GrantFiled: October 17, 2001Date of Patent: October 31, 2006Assignee: Flabeg Solarglas GmbH & Co., KGInventors: Hans-Joachim Becker, Armin Dauwalter, Andreas Gombert, Walther Glaubitt, Thomas Hofmann, Monika Kursawe

Patent number: 7125578Abstract: A method using polyelectrolyte self-assembly for preparing multi-layered organic molecular materials having individual layers which exhibit ultrafast electron and/or energy transfer in a controlled direction occurring over the entire structure. Using a high molecular weight, water-soluble, anionic form of poly-phenylene vinylene, self-assembled films can be formed which show high photoluminescence quantum efficiency (QE). The highest emission QE is achieved using poly(propylene-imine) (PPI) dendrimers as cationic binders. Self-quenching of the luminescence is observed as the solid polymer film thickness is increased and can be reversed by inserting additional spacer layers of transparent polyelectrolytes between each active conjugated layer, such that the QE grows with thickness. A red shift of the luminescence is also observed as additional PPV layers are added. This effect persists as self-quenching is eliminated. Charge transfer superlattices can be formed by additionally incorporating C60 acceptor layers.Type: GrantFiled: April 23, 1999Date of Patent: October 24, 2006Assignee: Los Alamos National Security, LLCInventor: Duncan W.
