Patent number: 7935428Abstract: The invention relates to a component made from a substrate with a coating, whereby that coating forms a surface of the component with reduced wettability. The invention further relates to production of said component. The coating which forms a surface with projections and recesses, brings about a reduction in wettability, in particular, by means of an effect based on the properties of lotus blossom. According to the invention, a metal with antimicrobial properties, in particular silver is provided under the coating, which is not fully covered, in other words, regions remain free of the coating in which the surface of the component is formed by the antimicrobial properties.Type: GrantFiled: January 31, 2006Date of Patent: May 3, 2011Assignee: Siemens AktiengesellschaftInventors: Christian Doye, Ursus Krüger, Manuela Schneider

Publication number: 20110014445Abstract: A glass sheet is formed using a roll-to-roll glass soot deposition and sintering process. The glass sheet formation involves forming a first glass soot layer on a deposition surface of a soot-receiving device, removing the first glass soot layer from the deposition surface, and forming a second glass soot layer on the unsupported first glass soot layer. The resulting composite glass soot sheet is heated to form a sintered glass sheet. The glass sheet can be a substantially homogeneous glass sheet or a composite glass sheet having layer-specific attributes.Type: ApplicationFiled: July 17, 2009Publication date: January 20, 2011Inventor: Daniel Warren Hawtof

Patent number: 7871949Abstract: A light emitting device includes: a first substrate; a second substrate; a light emitting unit interposed between the first substrate and the second substrate; and a sealing material bonding the first substrate to the second substrate and sealing the light emitting unit. The sealing material comprises V+4. In addition, a glass frit, a composition for forming a sealing material, and a method of manufacturing a light emitting device using the composition for forming a sealing material are provided to obtain the light emitting device. The sealing material of the light emitting device can be easily formed by coating and irradiation of electro-magnetic waves, so that manufacturing costs are low and deterioration of the light emitting unit occurring when sealing material is formed can be substantially prevented.
