Publication number: 20090091549Abstract: A touch panel includes multiple belt-like upper conductive layers and lower conductive layers formed in an orthogonal direction to the upper conductive layers. Those two kinds of layers are formed on a light transmissible substrate. A strong adhesion layer and a weak adhesion layer are layered together on a top face or an underside of the light transmissible substrate. The presence of the weak adhesion layer allows peeling off the touch panel from a cover of an apparatus fairly easier when the touch panel needs to be retrofitted to the cover. Since the weak adhesion layer is peeled off together with the strong adhesion layer, it will not be transferred or attached onto the cover. No time or labor is thus needed for removing the layer transferred or attached to the cover. The touch panel capable of being retrofitted with ease is thus obtainable.Type: ApplicationFiled: October 6, 2008Publication date: April 9, 2009Inventors: Kenichi Matsumoto, Koji Tanabe

Patent number: 6951595Abstract: A method of forming a reinforced polymer film structure is disclosed that includes the steps of slitting a biaxially oriented polymer film web having a top face and a bottom face into a first portion and a second portion, identifying the first portion and the second portion, and placing the first portion atop the second portion, such that the bottom face of the first portion is adjacent the top face of the second portion. This structure provides an impact and tear resistant laminate. Also disclosed is a method of forming a polymer film structure by identifying a molecular orientation direction profile of two portions of biaxially oriented polymer film and layering the two portions such that a molecular orientation direction profile of one does not coincide with a molecular orientation direction profile of the other.Type: GrantFiled: March 19, 2004Date of Patent: October 4, 2005Assignee: Mitsubishi Polyester Film, LLCInventors: Charles David Carlson, Jr., Russell Scott Foxhall

Patent number: 6949280Abstract: A sheet of unidirectionally-oriented fiber strands includes unidirectional fibers, bonding fibers interwoven with the unidirectional fibers to form a fiber panel, and thermoplastic film laminating the fiber panel there between. In one embodiment, a second sheet of laminated unidirectional fibers is joined to the first sheet of laminated unidirectional fibers with the unidirectional fibers running in a second direction as compared to the first fibers. In yet another embodiment, individual laminated sheets of unidirectional fibers are stitched together to form packets of sheets which may be used singularly or multiple packets may be bundled together.Type: GrantFiled: April 22, 2003Date of Patent: September 27, 2005Assignee: Survival, IncorporatedInventors: Lee Walker Brillhart, III, Ricky William Stewart, Ronald G. Krueger

Patent number: 6929841Abstract: The invention relates to a plastic-based composite product which consists at least partially of a plastic in which a material consisting substantially of particles is homogeneously embedded, which particles have tensile strength in at least one principal direction. The invention provides a product of the stated type which has the special feature that the particles comprise: small particles, in particular plates or fibres, with a random orientation and a length of 0.2-2 mm; and large particles with a dominant orientation, for instance 80-95%, of the said principal direction of the particles in a chosen product principal direction and a length in the particle principal direction of about 2-6 mm.Type: GrantFiled: April 27, 1995Date of Patent: August 16, 2005Assignee: Tech-Wood International Ltd.Inventors: Dirk Van Dijk, Franciscus B. A. De Vries

Patent number: 6926953Abstract: Copolymer structures are formed by exposing a substrate with an imaging layer thereon to two or more beams of selected wavelengths to form interference patterns at the imaging layer to change the wettability of the imaging layer in accordance with the interference patterns. A layer of a selected block copolymer is deposited onto the exposed imaging layer and annealed to separate the components of the copolymer in accordance with the pattern of wettability and to replicate the pattern of the imaging layer in the copolymer layer. Stripes or isolated regions of the separated components may be formed with periodic dimensions in the range of 100 nm or less.Type: GrantFiled: March 15, 2004Date of Patent: August 9, 2005Assignee: Wisconsin Alumni Research FoundationInventors: Paul F. Nealey, Juan J. DePablo, Francesco Cerrina, Harun H. Solak, XiaoMin Yang, Richard D. Peters, Qiang Wang

Patent number: 6919118Abstract: A plurality of unidirectional sheets (30a, 30b, 30c) are superposed in different directions and they are bonded together. At least one of the unidirectional sheets is made by spreading a tow so as to obtain uniform thickness, width not less than 5 cm, and a weight of no more than 300 g/m2, cohesion being imparted to the sheet so as to enable it to be handled prior to being superposed with other sheets. Advantageously, the unidirectional sheets are made of carbon fibers and are obtained by spreading out large tows.Type: GrantFiled: December 27, 2002Date of Patent: July 19, 2005Assignees: Societe Nationale d'Etude et de Construction de Moteurs d'Aviation-SNECMA, Hexcel ReinforcementsInventors: Bruno Bompard, Pierre Olry, Renaud Duval, Alain Bruyere, Dominique Coupe, Jean Aucagne

Patent number: 6918998Abstract: An on-machine-seamable industrial fabric comprising rings connected by pintles. In one principal embodiment, the rings are oriented in the machine direction and the pintles extend at an angle, connecting the rings. Such configuration improves the strength of the fabric and provides resistance to needling damage. In another principal embodiment, the rings are oriented in the cross-machine direction and the pintles extend in the machine direction, joining the rings.Type: GrantFiled: November 13, 2002Date of Patent: July 19, 2005Assignee: Albany International Corp.Inventor: Robert A. Hansen

Patent number: RE40207Abstract: An organic shell inlay blank is provided including a first layer of organic shell matter having two opposed surfaces defining a first thickness therebetween rendering the first layer flexible, a second layer of organic shell matter having two opposed surfaces defining a second thickness therebetween rendering the second layer flexible. One of the surfaces of the first layer substantially overlaps and is secured to one of the surfaces of the second layer. A bonding agent secures the layers together to form the inlay blank. A method for manufacturing an organic shell inlay blank is also disclosed and includes the steps of cutting a plurality of flexible pieces of organic shell matter from an organic shell, stacking the pieces in a substantially overlapping relationship with a bonding agent between the pieces, and urging the pieces together while the bonding agent cures to form the inlay blank.Type: GrantFiled: August 13, 2004Date of Patent: April 1, 2008Inventors: Lawrence J. Sifel, Charles W. Erikson
