Patent number: 7807258Abstract: A composite structure is provided. In another aspect of the present invention, a composite structure has relative layer-to-layer fiber orientations of between approximately 5° and 15°, inclusive. A further aspect of the present invention employs relative fiber offset angles less than 30° on a curved section. Yet another aspect of the present invention provides a three-dimensionally woven configuration where the first sheet is interwoven or mechanically linked with both the adjacent second layer and the opposite third or deeper layer.Type: GrantFiled: September 21, 2007Date of Patent: October 5, 2010Assignee: Board of Trustees of Michigan State UniversityInventors: Dahsin Liu, Peter Schulz

Patent number: 7687153Abstract: A donor substrate for laser transfer comprises: a base film; a light-to-heat conversion layer formed on the base film; and a transfer layer formed of an organic material on the light-to-heat conversion layer. The transfer layer contains a thermosetting electroluminescent material, and an organic electroluminescence display device is manufactured using the same. Thus, R, G and B emission layers are simply formed with a fine pattern by a thermal curing process after laser transfer. As a result, the emission layers are not damaged, and the manufacturing cost of a full-color organic electroluminescence display device is reduced due to employment of a simplified mask process. The donor substrate is advantageous to use in the manufacture of a large-sized organic electroluminescence display device.Type: GrantFiled: November 10, 2004Date of Patent: March 30, 2010Assignee: Samsung Mobile Display Co., Ltd.Inventors: Nam-Choul Yang, Seong-Taek Lee, Min-Chul Suh, Tae-Min Kang, Mu-Hyun Kim, Byung-Doo Chin

Patent number: 7371470Abstract: A light-emitting compound that can be easily applied to vacuum vapor deposition and exhibit long wavelength light is disclosed. Further, a light-emitting element without inferior luminescence properties due to the carbonization of a light-emitting compound during vapor deposition; and a light-emitting device that is composed of the light-emitting elements are also disclosed. A pyran derivative is represented by the following general formula 1: wherein R1 is a hydrogen element or an alkoxy group.Type: GrantFiled: April 4, 2007Date of Patent: May 13, 2008Assignee: Semiconductor Energy Laboratory Co., Ltd.Inventors: Sachiko Yamagata, Hiroko Abe, Nobuharu Ohsawa, Ryoji Nomura, Satoshi Seo

Patent number: 6979487Abstract: An improved printed article and a method of making same. The article including a substrate having a top surface and a bottom surface, with a reflective layer printed on the top surface of the substrate, a graphic design layer printed on the reflective layer, a textured pattern of transparent ink printed over the graphic design and reflective layer, and a glossy layer of transparent ink printed over the textured pattern and reflective layer. The glossy layer is printed over the entire surface of the substrate. The graphic image is printed through a four-color printing process over portions of the reflective layer. The textured pattern includes a plurality of light bending convex lines of transparent ink printed on and around the graphic image and reflective layers. The lines produce a reflective glossy textured surface on the printed article creating the illusion of depth and three-dimensionality.Type: GrantFiled: March 26, 2001Date of Patent: December 27, 2005Assignee: Serigraph Inc.Inventors: Joel Scott Scarbrough, Daniel C. Faul
