The wire is softer than the glass material and does not damage the surface of the glass material.Type: GrantFiled: June 1, 2000Date of Patent: April 23, 2002Assignee: Motorola, Inc.Inventors: Charles A. Rowell, David W. Jacobs, Edward A. Zarbock

Patent number: 6346290Abstract: Methods and apparatus for the preparation and use of a substrate having an array of diverse materials in predefined regions thereon. A substrate having an array of diverse materials thereon is generally prepared by delivering components of materials to predefined regions on a substrate, and simultaneously reacting the components to form at least two materials. Materials which can be prepared using the methods and apparatus of the present invention include, for example, covalent network solids, ionic solids and molecular solids. More particularly, materials which can be prepared using the methods and apparatus of the present invention include, for example, inorganic materials, intermetallic materials, metal alloys, ceramic materials, organic materials, organometallic materials, non-biological organic polymers, composite materials (e.g., inorganic composites, organic composites, or combinations thereof), etc.Type: GrantFiled: July 31, 1998Date of Patent: February 12, 2002Assignees: Symyx Technologies, Inc., The Regents of the University of CaliforniaInventors: Peter G. Schultz, Xiaodong Xiang, Isy Goldwasser

Patent number: 6337119Abstract: Master discs and similar devices used in the production of digital data storage and recording discs and the like are produced with a substrate member which is provided with a layer of material which is applied to the substrate member in liquid form of a thickness greater than the surface roughness of the substrate member and of a thickness greater than any particulates present on the substrate member. The material layer is preferably a polymer such as epoxy, acrylic or styrene and is hardenable by exposure to UV light, heat, air circulation or catalytic reaction to provide a substantially smooth flat surface for receiving a data bearing film. The film may be treated to generate bumps or pits representing digital signals, for example, which are free of any defects resulting from surface roughness or contamination of the substrate member.Type: GrantFiled: February 21, 1995Date of Patent: January 8, 2002Assignee: Headway Research, Inc.Inventor: Vern D. Shipman

Patent number: 6337029Abstract: A composition comprising bifluoride salts in a somewhat viscous form for roughening glass, ceramic and porcelain surfaces in preparation for refinishing includes: a. bifluoride salts in an amount ranging from 10.0 to 85.0 parts by weight; b. thickener in an amount ranging from 0.1 to 5.0 parts by weight; c. organic solvent in an amount ranging from 2.0 to 20.0 parts by weight; and d. water in an amount ranging from 7.0 to 75.0 parts by weight. A coating of the composition is applied to a substrate, such as those having low surface tensions and to which paint adhesion is difficult. The coating is left in contact with the substrate for a period of time effective to roughen the substrate. The coating is then removed and discarded or alternatively, collected and reused. The substrate after treatment will have a roughened surface from which improved paint adhesion results.Type: GrantFiled: January 21, 1999Date of Patent: January 8, 2002Assignee: Xim ProductsInventors: Richard D. Hardy, Juan E. Jarufe

Patent number: 6299940Abstract: A glass ceramic article is decorated with ceramic paints in a screen printing process in accordance with which two, mutually corresponding grate-shaped structural elements are arranged on the surface of the glass ceramic article to form a closed, full-surface decorative coating so that the surface beneath it is not visible. The first structural element consists of ceramic paint members covering respective separate parts of the surface with intermediate spaces between them, while the second grate-shaped structural element consists of other ceramic paint members covering the intermediate spaces between the ceramic paint members of the first structural element but only at most overlapping edges of the ceramic paint members of the first structural element without covering them. The closed full-surface decorative coating can have a two-color pattern, such as a black and white pattern.Type: GrantFiled: July 2, 1998Date of Patent: October 9, 2001Assignee: Schott GlasInventors: Susanne Rapp, Holger Sieck

Patent number: 6294218Abstract: In a process for coating a substrate, a texture (4) is created in a portion of its surface. A first layer (5) to be applied on the surface of the substrate adheres better to the texture (4) than it does to a surface area located outside of the texture (4). Then, the layer (5) is applied to the surface of the substrate and after that, areas of the layer projecting laterally beyond the texture (4) are mechanically removed. The material of the texture (4) contains at least one chemical element or a compound, which the layer (5) does not have or has only in a smaller concentration than the material of the texture (4). On the first layer (5), at least one second layer (7) is then applied which does not have the chemical element or compound contained in the material of the texture (4), or it has it only in a smaller concentration than the material of the texture (4).Type: GrantFiled: June 25, 1999Date of Patent: September 25, 2001Assignee: Micronas GmbHInventors: Günter Igel, Joachim Krumrey

Patent number: 6231924Abstract: The present invention provides a method of partially forming oxide layers on a surface of a substrate such as a glass plate by forming an oxide layer on the surface of the substrate, partially contacting the surface of the oxide layer formed on the substrate with an inorganic compound different from the oxide, dissolving partially the layer with the inorganic compound and removing the dissolved components of the layer together with the inorganic compound, by which the oxide layers are partially formed on the surface of the substrate efficiently and surely.Type: GrantFiled: May 26, 1999Date of Patent: May 15, 2001Assignee: Nippon Sheet Glass Company, LimitedInventors: Koichi Sakaguchi, Shigeki Nakagaki, Yasuto Sakai

Patent number: 6143375Abstract: A method for manufacturing a magnetic disk comprises the step of depositing a metallic layer on a glass substrate and laser texturing the metallic layer. The magnetic disk is then completed by deposition of (a) an underlayer such as Cr or sputtered NiP, (b) a magnetic layer such as a Co or Fe alloy, and (c) a protective overcoat such as ZrO.sub.2, carbon or hydrogenated carbon. By providing the above-mentioned metallic layer, laser texturing can now be used in conjunction with glass substrates.Type: GrantFiled: January 28, 1999Date of Patent: November 7, 2000Assignee: Komag, IncorporatedInventors: Caroline A.
