The method further includes compacting the carbon-filled laminate to admix the resin paste with the carbon fibers between the films, whereby to form the automotive carbon fiber-filled sheet molding compound.Type: GrantFiled: March 15, 2000Date of Patent: January 21, 2003Assignee: Patent Holding CompanyInventor: Frank W.

Publication number: 20030008074Abstract: A system and method for directing metal or ceramic particles toward a substrate (18) in a vacuum chamber includes a powder hopper (11), an enclosure (12) containing multiple differentially pumped vacuum chambers (19), a charging lamp (13), a tube (14), multiple charging and heating diodes 15, and an electromagnetic field generating device (EFGD) (17). The hopper (11) holds metal or ceramic particles, the chambers (19) propel the particles through the tube (14) towards substrate (18) positioned close to the tube, charging lamp (13) charges the particles, diodes (15) are used to heat the particles, and the EFGD (17) controls the direction of the particles propelled out of the tube.Type: ApplicationFiled: October 25, 2001Publication date: January 9, 2003Inventors: William Hofmeister, David Gustafson, Bridget Rogers

Patent number: 6503587Abstract: An oxygen-absorbing multi-layer laminate suitable for preserving food, etc. due to its excellent ability of retaining flavor and taste of food, a method of efficiently producing the oxygen-absorbing multi-layer laminate and a packaging container made of the oxygen-absorbing multi-layer laminate. The oxygen-absorbing agent is interspersed between a first thermoplastic resin layer and a second thermoplastic resin layer, or sandwiched between the integrally bonded first and second thermoplastic resin layers. In the oxygen-absorbing multi-layer laminate having at least three thermoplastic resin layers, the oxygen-absorbing agent is interspersed or interposed between the adjacent layers of at least one adjacent pair. With such a construction, the oxygen-absorbing ability is improved to prolong the storage life of retaining flavor and taste of food.Type: GrantFiled: March 11, 1999Date of Patent: January 7, 2003Assignee: Mitsubishi Gas Chemical Company, Inc.Inventors: Takashi Kashiba, Ryoji Otaki, Yoshiki Ito, Hideyuki Takahashi

Publication number: 20020166628Abstract: In a process for applying microcapsules to textile materials, microcapsules are initially introduced to the textile material without a binder, a dispersant is then introduced to disperse the microcapsules around and through the textile material, and thereafter a binder is added to promote adherence of the microcapsules to the textile material. Such a process advantageously provides for more thorough and even penetration of microcapsules and promotes increased adherence of microcapsules in a textile material, including fabrics and/or garments. Such a process uses a much shorter cycle time and is less expensive than conventional processes.Type: ApplicationFiled: May 9, 2001Publication date: November 14, 2002Inventors: Larry Harris, Larry F.

Patent number: 6471814Abstract: Disclosed is a method of accurately, simply forming a light absorbing layer for improving contrast in a transmission screen including micro glass beads two-dimensionally arranged. A light absorbing layer made from toner is formed on glass beads held in a transparent adhesive layer up to a thickness sufficient to cover the glass beads. The light absorbing layer is irradiated with parallel rays of light in the direction from a transparent substrate, to melt and remove only a portion of the light absorbing layer positioned over a light outgoing portion of each glass bead by the energy of the rays of light converged through the glass bead. By suitably selecting a material of the light absorbing layer, openings can be formed in the light absorbing layer by means of combustion, sublimation or ablation due to the energy of the converged rays of light.Type: GrantFiled: January 28, 2002Date of Patent: October 29, 2002Assignee: Sony CorporationInventors: Tomotaka Ito, Hidetoshi Watanabe
