Abstract:
A dope containing cellulose acylate as a main content of polymer is cast on a front surface of a moving belt in a method of producing a film from a solution. A drying apparatus is confronted to a back surface of said belt to evaporate a solvent in the gel-like film. Further, a condensers are confronted to a cast surface of said gel-like film to condense a solvent vapor for recovery. A wind speed above and near the gel-like film is from 0.01 m/s to 0.5 m/s, and the belt is transported downwards at the casting position PS. When d (mm) is a distance between the casting surface and each condenser, Tw (null C.) is a temperature of each condenser, and Ts (null C.) is a temperature of the casting dope, conditions are satisfied: Qnull(TsnullTw)/d and 5
Abstract:
A color filter composition comprises a mixture of a binder and a monomer in a predetermined ratio, a pigment, and a solvent. The predetermined ratio is a ratio of the binder to the monomer and ranges from about 50:50 to about 60:40. The color filter composition further comprises a solid powder having a weight percent in the color filter composition ranging from about 12% to about 18%, wherein the solid powder includes the pigment. The pigment has a weight percent in the solid powder ranging from about 28% to about 38%.
Abstract:
The present invention provides a method and apparatus for coating a light source to provide a modified output spectrum. Liquid adhesive is applied to the light source to form an adhesive layer. Luminescent material is fluidized and at least a portion of the adhesive layer immersed in the fluidized luminescent material to form a coated light source. The luminescent material can be a mixture of a phosphor compound and a fluidization enhancement substance, such as fumed silica.
Abstract:
A method for manufacturing an optical compensation film and the device thereof are provided. The method includes steps as follows. First, a horizontal condensing electric field orientation layer along an x-axis is formed by exposing a first linear photo reactive polymer layer on a first substrate under a transmissive polarized-light UV. Secondly, a first optical anisotropy film having the x-axis optic axis is formed on the horizontal condensing electric field orientation layer. Thirdly, a vertical condensing electric field orientation layer along a y-axis is formed on the first optical anisotropy film by exposing a second linear photo reactive polymer layer under a reflective polarized-light UV. Fourthly, a second optical anisotropy film having the y-axis optic axis is formed on the vertical condensing electric field orientation layer. Thereby, an optical compensation film with double optical-axes is formed.

In a method for preparing a radiation image storage panel comprising a support and a stimulable europium-activated cesium halide phosphor layer formed on the support by heating an europium-activated cesium halide phosphor or sources for production of the europium-activated cesium halide phosphor under reduced pressure to evaporate the phosphor or phosphor source and depositing the evaporated phosphor or phosphor source on a substrate, the deposition is preferably performed under the condition that a relationship between a molar ratio of europium to cesium in the deposited stimulable phosphor layer and a temperature of the substrate satisfies all of the formulas (1) to (3): Tnull867.24x0.4537nullnullFormula (1) Tnull0.0985xnull1.0587nullnullFormula (2) Tnull485.4x2null760.75xnull297.37nullnullFormula (3) in which T represents the temperature of the substrate in term of null C., and x represents a molar ratio of europium to cesium in the deposited stimulable phosphor layer.
Abstract:
Systems and methods are disclosed for an automatic and continuous supply of coating material to a coating applicator in optical fiber fabrication. The present invention switches from one coating reservoir to another by way of a transitional period in which both coating reservoirs are supplying coating material to the coating applicator. For example, while an in-use reservoir is supplying the coating material to the coating applicator, a standby reservoir is being filled, settled to off gas air bubbles and then slowly pressurized. A sized orifice is used to slowly bleed off pressure from the in-use reservoir at a rate that does not allow the pressure in the in-use reservoir from falling out of a desired pressure range. When the in-use reservoir is substantially emptied of coating material and the pressures in both reservoirs are substantially equalized, then both reservoirs simultaneously supply coating material to the coating applicator for a period of time before switching completely over to the standby reservoir.

Abstract:
Disclosed are methods for extracting excess materials from contact lenses, during which the contact lenses swell above their functional size. The methods include the steps of treating contact lenses with a liquid, preferably a solution that causes the contact lenses to swell to a size larger than their functional size, and treating the contact lenses with a liquid, preferably a solution that causes them to shrink back to their functional size.
Abstract:
On producing an antireflection-coated substrate which includes a transparent substrate (1) and an antireflection film formed on the transparent substrate, the antireflection film is made of a multilayer film having a medium refractive index layer (2), a high refractive index layer (3), and a low refractive index layer (4) successively formed on the transparent substrate in this order. The medium refractive index layer is made of a material containing silicon, tin, and oxygen. The high refractive index layer is made of a material containing oxygen and at least one element selected from a group consisting of titanium, niobium, tantalum, and hafnium. The low refractive index layer is made of a material containing silicon and oxygen. The antireflection film is formed by successively depositing these layers by an in-line sputtering apparatus.
