The plies are preferably heat strengthened glass in the thickness range of about 1.0-3.0 mm. The interlayer is preferably a plastic material, such as polyvinyl butyral, and has a thickness in the range of about 0.50-0.80 mm. A coating, such as a solar control coating or electroconductive coating, can be formed or deposited on one or more surfaces of the plies and/or interlayers. A method and apparatus are also provided for producing a laminated sidelite of the invention.Type: GrantFiled: February 25, 2000Date of Patent: June 24, 2003Assignee: PPG Industries Ohio, Inc.Inventors: C. Edward Brown, William S. Cunningham, Michael T. Fecik, Vaughn R. Imler, Alana R. Zajdel, William B. Zimmerman

Patent number: 6579608Abstract: The invention provides a laminated glass and a method of producing the same. This laminated glass includes first and second transparent glass plates and an interlayer film interposed therebetween. This interlayer film has functional ultra-fine particles which have a particle diameter of up to 0.2 &mgr;m and are dispersed therein. Due to the incorporation of the ultra-fine particles thereinto, the interlayer film is provided with various additional functions such as heat insulation, ultraviolet ray absorption and the maintenance of a sufficient radio transmittance. Therefore, the laminated glass becomes suitable as an architectural or automotive laminated glass.Type: GrantFiled: August 4, 2000Date of Patent: June 17, 2003Assignee: Central Glass Company, LimitedInventor: Takeshi Kondo

Publication number: 20030096116Abstract: A heat dissipating structure is provided which lowers the thermal contact resistance between a heat generating electronic component and a heat dissipating component, and markedly improves the heat radiation. The heat dissipating structure comprises a graphite sheet and a heat conducting material layer provided on at least one surface of the graphite sheet, and is positioned between the electronic component and the heat dissipating component. The heat conducting material has no fluidity at room temperature when the electronic component is not operating, but undergoes a reduction in viscosity, softens or melts, under the influence of heat generated during operation of the electronic component.Type: ApplicationFiled: November 15, 2002Publication date: May 22, 2003Applicant: Shin-Etsu Chemical Co., Ltd.Inventors: Kunihiko Mita, Akio Suzuki, Tsutomu Yoneyama

Publication number: 20030072950Abstract: The present invention is directed to an aqueous polymer composition comprising a copolymer and water, the copolymer containing at least one hydrophilic base or acid-neutralizable monomer and at least one hydrophobic ethylenically unsaturated monomer. A film formed from the contains essentially no crosslinking. The polymer composition is formed by polymerizing the hydrophilic monomer and hydrophobic monomer in a non-aqueous solvent; forming an aqueous polymer dispersion from the non-aqueous polymer solution, and adding a base or acid to form an aqueous polymer composition.Type: ApplicationFiled: August 1, 2001Publication date: April 17, 2003Inventors: Klein Rodrigues, Michael Eknoian

Patent number: 6531215Abstract: An antifogging article includes a substrate and an antifogging film covering the substrate. This antifogging film contains a water-absorbing organic polymer and an inorganic substance and has a water repellent finishing on a surface of the antifogging film. Another antifogging article includes (1) a substrate, (2) a water-absorbing, antifogging film covering the substrate, and (3) a water-permeable, protective film covering the antifogging film. This antifogging film contains (a) a polyvinyl acetal resin having a degree of acetalization of not greater than 10 mol % and (b) a hydrolysate or partial hydrolysate of an alkylsilylisocyanate. This constituent (b) can be replaced with at least one of a silylisocyanate, its hydrolysate, and its partial condensate. These antifogging articles are superior in antifogging property and abrasion resistance.Type: GrantFiled: April 17, 2001Date of Patent: March 11, 2003Assignee: Central Glass Company, LimitedInventors: Seiji Yamazaki, Noboru Murata, Hideki Yamamoto
