Patent number: 9856395Abstract: A coating composition, a method for coating a substrate and a pipeline are provided. The coating composition includes at least one epoxy resin and at least one functionalized elastomer. The functionalized elastomer includes an elastomer being grafted with acid anhydride-based groups. The method includes steps of applying the coating composition to the substrate, and curing the coating composition so as to obtain a coating. The pipeline includes a pipe and the coating formed from the coating composition coated on the pipe. The coating has improved flexibility, and improved heat and chemical resistance.Type: GrantFiled: October 30, 2015Date of Patent: January 2, 2018Assignee: LCY CHEMICAL CORP.Inventors: Yu-Tien Chen, Po-Nien Tsai, Ruoh-Huey Uang

Patent number: 9857572Abstract: A fixed-focus projection lens, in order from an image side to an image source side along an optical axis, includes a first lens with negative refractive power, a second lens with positive refractive power, a third lens with negative refractive power, a fourth lens with positive refractive power, a fifth lens with positive refractive power, and a sixth lens with positive refractive power. The second lens is a biconvex lens. While projecting, a light enters the fixed-focus projection lens from the image source side, and passes through the fixed-focus projection lens. Further more, at least one surface of the first lens is aspherical, a refractive index of the second lens is greater than 1.8, and a refractive index of the fifth lens is greater than 1.7. Such arrangement helps to lower a spherical aberration of spherical lens, shortening the optical system, and effectively lower the distortion.Type: GrantFiled: August 11, 2016Date of Patent: January 2, 2018Assignee: CALIN TECHNOLOGY CO., LTD.Inventors: Chien Hsiung Tseng, Yi-Ling Yang, Po-Nien Tsai
