Patent number: 7459211Abstract: Disclosed is an anti-UV reflector for distributing a light from a point light source or a linear light uniformly over a target. The anti-UV reflector mainly includes a light reflecting polymeric substrate and a protecting layer of anti-UV material provided on the polycarbonate substrate for reducing yellowing in the polycarbonate substrate. When a light from a point light source or a linear light illuminates the anti-UV reflector, UV radiation in the light is filtered or absorbed by the protecting layer thereby reducing yellowing in the polyearbonate substrate.Type: GrantFiled: August 11, 2006Date of Patent: December 2, 2008Assignee: Chi Lin Technology Co., Ltd.Inventors: Hsi-Hsin Shih, Kuo-Lung Wu, Tien-Chieh Chang, Shih-Kai Cheng, Mao-Song Lee

Patent number: 5837085Abstract: A method of making a toothed belt. A toothed belt is made by guiding a strip of fabric to pass through a thermosetting resin to soak it with thermosetting resin, then the soaked fabric is guided to pass through a pair of toothed rollers to form a series of toothed grooves thereon, thereafter the fabric is guided to pass around a plane roller and simultaneously rubber material is fed into the space between the outer peripheral surface of the plane roller and said fabric. Then, the fabric is wound onto a cylindrical mold having corresponding toothed grooves thereon and its two ends are glued together to loop around the cylindrical mold, then reinforcing cords and rubber sheets are covered over the fabric. Finally, the rubber material is vulcanized to form a toothed belt. Fabrics treated by the method demonstrate considerately greater flexibility or extendibility to comply with bending when under operation. Furthermore, the tooth contour of the belt will be more accurate than conventional ones.Type: GrantFiled: April 16, 1996Date of Patent: November 17, 1998Assignee: Industrial Technology Research InstituteInventors: Te-Cheng Chen, Mao-Song Lee, Ruey-Sheng Shih, Huo-Sheng Liao
