Patent number: 6366012Abstract: A CRT has an improved contrast with the provision of a filter layer where nano-sized metal particles and colored particles are dispersed in a dielectric matrix to selectively absorb light in predetermined wavelengths, specifically wavelengths between peak wavelengths of primary colors emitted by phosphors coated on the inner surface of the faceplate. The improved contrast is a result of the metal particles in a dielectric matrix resonating with particular wavelengths and thus absorbing them.Type: GrantFiled: April 28, 2000Date of Patent: April 2, 2002Assignee: Samsung SDI Co., Ltd.Inventors: Jong-Hyuk Lee, Jung-Hwan Park, Yoon-Hyung Cho, Hae-Sung Lee, Dong-Sik Zang

Patent number: 6245694Abstract: Automotive bedliners (e.g., for pickup trucks) are formed from a sheet of thermoplastic material having electrically conductive fibers embedded in a surface thereof in an amount sufficient to render said sheet electrically conductive. The bedliners are most preferably formed of a thermoplastic material (e.g., a polyolefin, such a polyethylene and/or polypropylene) having a matrix of electrically conductive fibers physically embedded in at least one side thereof. By physically embedding the conductive fibers in a surface of the bedliner, the fibers are capable of establishing electrical continuity between the bedliner and the pickup truck bed thereby effectively dissipating static electrical charges.Type: GrantFiled: October 1, 1997Date of Patent: June 12, 2001Assignee: Shakespeare Conductive Fibers, LLCInventors: Grover L. Davenport, Wayne S. Stanko, Allen Ray, Everett C. Cox, Michael A. Davis, Gary M. Carnes
