摘要:
A method of forming a porous silica film includes the following steps: a) providing a substrate; b) coating, on a surface of the substrate, a layer of charged polyelectrolyte; and c) applying an aged silica-bearing non-colloidal solution to the coated surface of the substrate to adsorb porous silica thereon. The adsorption cycle of steps (b) and (c) is repeated a number of times to control film thickness. The age and concentration of the silica-bearing solution are selected to control the porosity and the index of refraction of the porous silica film.

A method for creating an optical structure includes forming a layer of chalcogenide material upon a substrate, and applying a patterned stamper to the layer of chalcogenide material, in the presence of heat, the patterned stamper causing the layer of chalcogenide material to reflow such that stamped features of the patterned stamper are transferred onto the layer of chalcogenide material. The stamped features onto the layer of chalcogenide material are used to form one of an optical waveguide, an optical mirror, digital video disk data, compact disk data and combinations comprising at least one of the foregoing.
摘要:
A process for forming a retroreflective layer on a powder coated substrate is provided. The substrate is powder coated and the powder coating is subsequently partially cured. Reflective elements are then partially embedded in the semi-cured powder. The powder is then fully cured to permanently bond the reflective elements with the powder coating. The resultant retroreflective assembly can be used in any application requiring high detectability in poor visibility conditions, such as road signs and the like.

A method for creating a pattern by applying varying concentrations of pigment in water to a synthetic fabric and allowing the pigment to bleed and preferably to reverse bleed. A pleated window shade having an Aurora Borealis like pattern is also provided. The preferred method comprises the steps of stretching a pleated synthetic fabric window shade vertically, applying pigment in water to the surface of the fabric and allowing the pigment to bleed, then inverting the fabric so that the pigment in solvent bleeds in the opposite direction. Optionally, the method further includes at least one of the steps of applying the solvent, such as for example water, to the pigmented surface before inverting or after inverting thereby inducing additional bleeding, blending, and dilution of the pigment in the wetted area.
摘要:
A method for producing a light source bulb wherein a shielding film is formed on the outer peripheral face of a glass tube extending along a reference bulb axis, such that a coating for providing the shieiding film can be applied efficiently and precisely onto the outer peripheral face of the glass tube even though the shielding film is complicated in configuration. The method includes horizontally placing a light source bulb, vertically placing a coating discharging portion, moving a front edge face of the coating discharging portion close to the outer peripheral face of the shroud tube, and applying the coating by moving the coating discharging portion and the light source bulb relative to each other along a reference bulb axis and rotating the light source bulb upon the reference bulb axis while the coating is being discharged from the coating discharging portion.
摘要:
The method and formula for tinting glass described herein employs a transparent acetate lacquer. The transparent acetate lacquer is derived from a base of cellulose acetate dissolved in an appropriate solvent. Preferably, additional ingredients are added to the formula to provide a lacquer that is easy to apply and which provides superior adhesion to the glass. The method of this invention includes applying a transparent acetate lacquer to glass and allowing the lacquer to dry. Application of the lacquer may be conducted by any conventional method including spraying and brushing. When dried, the lacquer provides excellent tinting properties.

The present invention relates to a transparent conductive thin film and a method for the preparation of the same., and more particularly to a method for the preparation of a transparent conductive thin film comprising the steps of a) preparing a sol solution of antimony-tin oxides (ATO) or indium-tin oxides (ITO), b) forming a transparent coating layer on an outer surface of a cathode ray tube using the sol solution, and c) rapidly increasing a temperature of the transparent coating layer to a predetermined temperature of 300 to 1200° C., and rapidly cooling the transparent coating layer either immediately or after maintaining the predetermined temperature for up to 20 seconds, and a transparent conductive thin film prepared by this preparation method, i.e., a transparent conductive thin film which not only has superior conductivity, high hardness, and non-reflectivity but also saves production process time and increases production process effectiveness, and a method for the preparation of the same.
摘要:
A method is used by a semiconductor processing tool. The method comprises forming a first layer above a substrate layer, and forming an inorganic bottom antireflective coating layer above the first layer by introducing at least two gases at a preselected ratio into the semiconductor processing tools. A signal indicating that the semiconductor processing tool has been serviced is received, and the ratio of the gases is varied in response to receiving the signal to control optical parameters of the bottom antireflective coating layer to enhance subsequent photolithographic processes.

A method and apparatus are provided for batch, continuous, or semi-continuous coating of optical lenses. The method and apparatus use a plurality of carriages which are reciprocally moved in the apparatus to transfer jigs from a jig filled carriage to a lens loading arm and to load the jigs with lenses and then to transfer the jigs now containing uncoated lenses to a leading empty carriage. Using such a reciprocating motion, a leading empty carriage is now filled with jigs containing uncoated lenses and the uncoated lenses in the carriage may then be coated by dipping the carriage in a coating tank. After coating, the coated lenses are removed from the system. A similar reciprocating motion is used in the coated lens unloading section.
