A solution, prepared by dissolving an organic dye in an organic solvent, is applied onto the light-transmittable substrate by a spin coating method to form an organic dye layer. A reflecting layer is formed on the organic dye layer without performing a drying treatment of the organic solvent in the organic dye layer, followed by forming the protective layer on the reflecting layer. The result is an optical recording medium containing an organic solvent in an organic dye layer in an amount of 2% to 15% by weight based on an organic dye.Type: GrantFiled: April 18, 2000Date of Patent: February 22, 2005Assignee: TDK CorporationInventors: Kazuki Suzawa, Hiroyuki Arioka, Tomoki Ushida

Patent number: 6852390Abstract: A durable ultraphobic surface that is capable of retaining ultraphobic properties at liquid pressures of one atmosphere and above. The surface generally includes a substrate portion with a multiplicity of projecting regularly shaped microscale or nanoscale asperities disposed so that the surface has a predetermined contact line density measured in meters of contact line per square meter of surface area equal to or greater than a contact line density value “?L” determined according to the formula: ? L = - 10 ? , ? 330 ?cos ? ( ? a , 0 + ? - 90 ? ° ) where ? is the surface tension of the liquid in Newtons per meter, ?a,0 is the experimentally measured true advancing contact angle of the liquid on the asperity material in degrees, and ? is the asperity rise angle in degrees.Type: GrantFiled: June 3, 2003Date of Patent: February 8, 2005Assignee: Entegris, Inc.Inventor: Charles W. Extrand

Patent number: 6852252Abstract: The present invention relates to incorporating metal nanoshells specifically designed to interact with triplet excitons in polymers. By interacting with triplet excitons, the rate of photo-oxidation can be slowed and the density of luminescence-quenching traps can be reduced.Type: GrantFiled: April 6, 2001Date of Patent: February 8, 2005Assignee: William Marsh Rice UniversityInventors: Nancy J.

Patent number: 6846537Abstract: An article and method for reinforcing structural members is provided. The article comprises a carbon fiber material, preferably a carbon fiber mesh with a roughened surface defined by an epoxy resin. The article has lateral fibers woven into longitudinal carbon fibers that are in tension, creating a mesh. An epoxy resin is applied to the fiber mesh to form a rigidified fiber mesh tape once the resin is cured. To obtain a roughened surface a plastic sheet is removably attached to the surface of the fiber mesh. The plastic sheet is removed thereby exposing a roughened carbon fiber surface defined by the epoxy. The rigidified fiber mesh tape is adhered to the structural member by applying a second epoxy to the structural member. The roughened surface of the rigidified carbon fiber mesh material is then joined to the second epoxy resin. To firmly adhere the fiber mesh to the structural member an impermeable material and a plastic barrier are placed above the article and the structural member.Type: GrantFiled: July 11, 2001Date of Patent: January 25, 2005Inventors: Donald G. Wheatley, Donald E. Wheatley

Patent number: 6843871Abstract: Disclosed is a process for preparing a fibrous web. The fibrous web includes a microencapsulated material, such as a microencapsulated phase change material, adhered to the web. Preferably, the web is prepared in a melt-blowing or spun-bonding process. In the melt-blowing process, cooling water containing the microcapsules is used to cool melt blown fibers prior to collection on a collector. In the spun-bonding process, microcapsules are applied in liquid suspension or in dry form to a heated web, for instance, after the web has been calendared. The fibrous webs thus prepared have numerous uses, and are particularly suited to the manufacture of clothing.Type: GrantFiled: November 15, 2002Date of Patent: January 18, 2005Assignee: Appleton Papers Inc.Inventors: Michael Paul Bouchette, David Paul Kendall

Patent number: 6842545Abstract: Optoelectronic and photonic devices are formed by employing polymer materials that have a lower glass transition temperature (Tg) than the nominal operating temperature. By using such materials, the local or segmental mobility is increased so that local stress is eliminated or minimized on the polymer material, making performance more robust. The current invention involves use of a polymer in an optical device in an operating temperature range in the region above Tg, where the polymer segments between crosslinks are allowed local freedom of movement; however, large-scale movement of the material may be restricted by the crosslinked structure of the polymer material.Type: GrantFiled: April 5, 2001Date of Patent: January 11, 2005Inventors: Hilary Sue Lackritz, Tony C. Kowalczyk, Yeong-Cheng Lee, David A. G. Deacon

Patent number: 6838180Abstract: The invention concerns transparent fire break glass panels. The inventive glazing comprises at least two glass sheets and an intumescent phosphate-based material layer, layer which is located between said two glass sheets. The intumescent material comprises pyrogenous silica or a mixture of pyrogenous silica and alumina which enables said material to be exempt from creep deformation at temperatures preceding the expansion of the intumescent material in fire resistance tests. The inventive glass panels have proved heat resistance, and are more easily manufactured than similar glass panels in prior art.Type: GrantFiled: September 11, 2000Date of Patent: January 4, 2005Assignee: GlaverbelInventors: Pierre Goelff, Guy Mertens, Xavier Dallenogare, Mehdi Ghodsi
