  • Patent number: 8857372
    Abstract: An isothermal, low pressure-based process of depositing material within a substrate has been developed and results in creating an extremely narrow reaction zone within which a more uniform and efficient deposition will occur. Sets of isothermal plasma operating conditions have been found that create a narrow deposition zone, assuring that the deposited material is clear glass rather than soot particles. The chemical delivery system, in one arrangement, utilizes rods of solid phase source material (which may otherwise be difficult to obtain in gaseous form). The operating conditions are selected such that the hot plasma does not transfer a substantial amount of heat to the substrate tube, where the presence of such heat has been found to result in vaporizing the reactant material (creating soot) and developing hot spots.

  • Patent number: 8852678
    Abstract: Glass surfaces, for example, windshield surfaces, have a durable hydrophobic coating applied thereto. The glass surface is first treated by any suitable method to enhance the ability of a chitosan polymer coating to durably or substantially permanently adhere thereto. Once the chitosan coating has been applied to the glass surface, the normally hydrophilic chitosan coating is rendered hydrophobic by suitable treatment, for example, by a combination of enzymatic and chemical treatments. Alternatively, the chitosan may be rendered hydrophobic prior to coating it on the glass surface, but that is a less preferred technique. The method of the invention provides a glass article having a hydrophobic surface.

  • Patent number: 7247347
    Abstract: A method of coating an optical fiber includes a step of coating the fiber with a curable coating composition and a step of curing the composition, which contains an unsaturated compound having a double bond and an oxidation catalyst. The curing step includes an in-line first phase consisting in exposing the coated fiber to UV radiation for a time shorter than the time needed for complete curing followed by an off-line second phase consisting in placing the coated fiber in an oxidizing medium in order to complete curing.

  • Patent number: 7136562
    Abstract: A process for forming a light guide plate with a reflection film includes: (a) providing a light guide plate (30), which has a light input surface (303) with light incident portions (3032), a bottom surface (304), a light output surface (301), and side surfaces (302); (b) attaching protection film (32) on the light incident portions and the light output surface; (c) providing a reflection solution; (d) dipping the light guide plate in the reflection solution; (e) removing the light guide plate from the reflection solution, and solidifying a portion of the reflection solution remaining on the light guide plate to thereby form a reflection film; and (f) removing the protection film to expose the light incident portions and the light output surface. Because the reflection film is directly attached to the light guide plate, there is no gap and no attendant leakage of light.

  • Patent number: 7128944
    Abstract: The invention relates to thermally tempered safety glass comprising an non-abrasive and porous SiO2 layer which is stable during sintering and has a refractive index of between 1.25 and 1.40. The inventive safety glass can be obtained by coating standard soda-lime glass with an aqueous coating solution having a pH value of between 3 and 8 and containing between 0.5 and 5.0 wt. % of [SiOx(OH)y]n particles (0<y<4 and 0<x<2) having a particle size of between 10 and 60 nm, and a surfactant mixture. The coated glass is then dried, thermally hardened at temperatures of at least 600° C. for several minutes, and thermally tempered by a flow of air.

  • Patent number: 7125578
    Abstract: A method using polyelectrolyte self-assembly for preparing multi-layered organic molecular materials having individual layers which exhibit ultrafast electron and/or energy transfer in a controlled direction occurring over the entire structure. Using a high molecular weight, water-soluble, anionic form of poly-phenylene vinylene, self-assembled films can be formed which show high photoluminescence quantum efficiency (QE). The highest emission QE is achieved using poly(propylene-imine) (PPI) dendrimers as cationic binders. Self-quenching of the luminescence is observed as the solid polymer film thickness is increased and can be reversed by inserting additional spacer layers of transparent polyelectrolytes between each active conjugated layer, such that the QE grows with thickness. A red shift of the luminescence is also observed as additional PPV layers are added. This effect persists as self-quenching is eliminated. Charge transfer superlattices can be formed by additionally incorporating C60 acceptor layers.

  • Patent number: 7078071
    Abstract: Glass/nanoparticle composites are provided which include a glass matrix with a high density of heterologous nanoparticles embedded therein adjacent the outer surfaces of the composite. Preferably, the glass matrix is formed of porous glass and the nanoparticles are yttrium-iron nanocrystals which exhibit the property of altering the polarization of incident electromagnetic radiation; the composites are thus suitable for use in electrooptical recording media. In practice, a glass matrix having suitable porosity is contacted with a colloidal dispersion containing amorphous yttrium-iron nanoparticles in order to embed the nanoparticles within the surface pores of the matrix. The treated glass matrix is then heated under time-temperature conditions to convert the amorphous nanoparticles into a crystalline state while also fusing the glass matrix pores.

  • Patent number: 7037573
    Abstract: An antireflection layer is formed directly or through an other layer at least on one side of a transparent base film of an antireflection film. The antireflection layer is made of at least two kinds of low refractive index materials satisfying a relationship of refractive index: nd20?1.49. The antireflection layer is excellent in antireflection characteristics and mar resistance. When the antireflection layer is formed on a hard coat layer having an uneven surface roughened by particles, the antireflection film is excellent in antiglareness.

  • Patent number: 6875642
    Abstract: A method for manufacturing thin film and a thin film. The method comprises dipping a substrate in a solution that dries up forming a layer on the surface of the substrate and controlling layer thickness by changing the rate of dipping the substrate in the solution. Before the next dipping after the first dipping, the position of the substrate is changed such that the next dipping will be carried out in a direction which is at an angle to the direction of the previous dipping.
