Patent number: 6861091Abstract: A self-assembly process for preparing luminescent organic-inorganic nanocomposite thin films is disclosed. A homogeneous solution in water and an organic solvent is obtained containing a soluble silicate, a silica coupling agent, a surfactant, and an organic material having a hole transport, electron transport, and/or emissive material moiety. The silica coupling agent is selected to chemically react with the organic material. A film of the homogeneous solution is deposited onto a substrate. Preferentially evaporating the organic solvent enriches the concentration of water and non-volatile solution components to promote micelle formation. Organic materials migrate into the hydrophobic portion of the forming micelles. Continued evaporation promotes self-assembly of the micelles into interfacially organized liquid crystalline mesophases. Reacting the organic material and silica coupling forms a nanostructure self-assembly.Type: GrantFiled: December 27, 2000Date of Patent: March 1, 2005Assignee: Canon Kabushiki KaishaInventor: Alan Sellinger

Patent number: 5965209Abstract: In an apparatus and method for forming an applied layer of a photosensitive resin on a large glass substrate for an LCD color filter, a substrate (S) is suctioned and held by a movable holder (8) with a main surface thereof to be processed oriented downward. The movable holder (8) is at an angle of inclination (.theta.) to the horizontal and is capable of moving along a guide rail (7). An application head (H) having an upward-pointing linear slit (13) through which an application liquid is supplied is provided below a region through which the substrate (S) moves supported by the holder (8). When the substrate (S) having a constant clearance (I.sub.2) with the application head (H) is moved diagonally upward, an application liquid bead (B) is formed between the slit (13) and the downward-pointing main surface of the substrate (S), by surface tension. The application liquid bead (B) is moved gradually diagonally downward along the main surface of the substrate to form an application layer (Ra). A meniscus (L.Type: GrantFiled: July 15, 1997Date of Patent: October 12, 1999Assignee: Dai Nippon Printing Co., Ltd.Inventors: Takayasu Komatsu, Shunji Miyakawa, Kazuo Watanabe

Patent number: 5913976Abstract: The invention comprises a fixture and method for holding optical waveguid such as fiber optic cable, in a relatively stable fashion for processing. The fixture includes a first frame and a second frame, releasably securable to the first frame to form a unitary structure. Chambers disposed in at least one of the frames are adapted for removably receiving optical fiber cable when the first and second frames are released from one another and for securely retaining with molding material optical fiber cables when the first and second frames form the unitary structure. A process area is defined in the unitary structure such that segments of optical fiber cables secured therein are accessible in the process area for processing. An optional coating fixture is securable to said unitary structure for forming with a molding material a protective coating about the cable segments in the processing area.Type: GrantFiled: September 9, 1996Date of Patent: June 22, 1999Assignee: The United States of America as represented by the Secretary of the NavyInventors: Scott L. Patton, Robert M. Payton

Patent number: 5900275Abstract: The haze in a conductive tin oxide coating deposited on a substrate, particularly glass, can be reduced by applying, to a desired thickness, a solid-state coating, where the solid-state layer is applied as a precursor liquid to the tin oxide layer, is then dried and/or converted to a solid-state film overlying the conductive tin oxide film on the substrate.Type: GrantFiled: July 15, 1992Date of Patent: May 4, 1999Assignee: Donnelly CorporationInventors: John P. Cronin, Anoop Agrawal, Michael Trosky

Patent number: 5882785Abstract: This invention is comprised of new nonlinear optic polymers and a new Lanir-Blodgett (LB) film deposition scheme for which these polymers were designed. The invention is unique because it produces an electro-optic film which has never undergone electric-field poling nor high temperature treatment. It eliminates the dilution effect of the long hydrophobic alkyl groups, and creates stronger ionic bonds between the polymer chains. Finally, the invention reduces the time to make a film of a given thickness by at least half by virtue of depositing two polymer layers per stroke. The new polymers are comprised of asymmetric chromophores linked head-to-head by alternating two different kinds of bridging groups. One of the bridging groups contains one or more ionic groups, and the other bridging group contains one or more non-ionic, hydrophilic groups.Type: GrantFiled: January 23, 1997Date of Patent: March 16, 1999Assignee: The United States of America as represented by the Secretary of the NavyInventors: Richard A.

Patent number: RE37682Abstract: A light influencing element and the process of fabricating the same is disclosed, wherein the light influencing element is fabricated by disposing a layer of a substantially opaque material upon a transparent substrate. One or more openings or wells may then be cut or formed in the surface of the layer of opaque material. Into such openings a light influencing material is then disposed, preferable said materials are injected thereinto as by ink-jet type injection heads. Liquid crystal displays and subassemblies formed upon the light influencing elements of the instant invention are also provided.Type: GrantFiled: November 16, 1999Date of Patent: April 30, 2002Assignee: LG.Philips LCD Co., Ltd.Inventor: Zvi Yaniv

Patent number: H2046Abstract: A process that lends itself to automation for producing multi-layer second-order nonlinear optical polymer (NLOP) thin films by the forming of a polycation layer containing an NLO-active cationic polymer, having non-centrosymmetric chromophores, on a substrate followed by the forming of a polyanion layer, also having non-centrosymmetric chromophores, on the polycation layer. A predetermind number of the polycation and the polyanion layers may be alternated upon the surface as well as one or more buffer layers. An added benefit is the formation of an ultra-smooth surface of the same order of roughness as the substrate upon which the layers are formed.Type: GrantFiled: October 22, 1997Date of Patent: September 3, 2002Assignee: The United States of America as represented by the Seceretary of the NavyInventors: M.
