Abstract:
A method for applying a coating to an optical surface of an optical device. In one embodiment, the method includes the steps of placing a coating solution in a cliche of a cliche plate, transferring the coating solution from the cliche to deformable body of a transfer pad, and pressing the transfer pad to the optical surface so as to transfer the coating solution from the deformable body of the transfer pad to the optical surface. The method further includes a step of irradiating the coating solution associated with the optical surface at a wavelength of microwave so as to form a coating layer on the optical surface. The coating layer can be further cured to form a desired coating on a proper optical surface. The optical device can be an optical lens having at least one optical surface, or a mold that can be used to produce an optical lens. In other words, the present invention allows a coating to be applied directly to an optical surface of an optical lens. Alternatively, a coating can be first applied to an optical surface of at least one mold and then be transferred to an optical surface of an optical lens during casting process.
Abstract:
The present invention generally relates to a method of modifying the surface of substrates such as contact lenses and other biomedical articles by at least partially coating the surfaces of such substrates with a polymeric tie layer having reactive sites. Various other moieties may then be chemically attached to the article surface by reaction of the other moieties with the reactive sites through classical chemical attachment mechanisms.
Abstract:
A method of transferring a transfer element of a donor sheet to a receptor includes forming an organic layer on a receptor substrate and forming a transfer element on a donor sheet, where the exposed surface of the transfer element is organic. Either the surface of the organic layer or the exposed surface of the transfer element (or both) is roughened using a plasma treatment. The transfer element of the donor sheet is then selectively thermally transferred to the surface of the organic layer.
Abstract:
Method of predicting optical properties and physical characteristics of coated paper or other sheet products for the purpose of formulating enhanced coating or sheet forming systems, and in particular to a method, which uses a diffusion approximation model derived from a radiative transfer theory employing various inputs of the properties and/or characteristics to predict coating or sheet system performance.
Abstract:
A display device comprising a multi-color light emitting layer and method of depositing the multi-color light emitting layer over a glass substrate are provided. The display device comprises multiple light emitting materials deposited over a glass substrate in coplanar relationship to each other. The method provides depositing one light emitting polymer material over one portion of the glass substrate and depositing other light emitting polymer materials over other portions of the glass substrate, such that the multiple light emitting polymer materials are deposited in a coplanar relationship to each other. The light emitting polymer materials are deposited using flexographic mats, the relief portion of which have patterns corresponding to the respective portions of the glass substrate being covered by the light emitting polymer materials being deposited.

Abstract:
A method including: dropping the ultraviolet-curable resin fluid onto the aspheric face of a metallic mold set horizontally, the aspheric face having a desired concave face; bringing a convex lens close to the metallic mold and stopping the movement of the lens just before it comes into contact with the ultraviolet-curable resin fluid; inclining the metallic mold and the lens together to cause the ultraviolet-curable resin fluid to flux; after bringing the convex face of the lens into point contact with this fluxed and swelled ultraviolet-curable resin fluid, moving the lens to a prescribed position relative to the metallic mold to place the ultraviolet-curable resin fluid between the lens and the metallic mold; returning the lens and the metallic mold together from the inclined state to the horizontal state, thereby irradiating the ultraviolet-curable resin fluid with ultraviolet rays to cure the resin fluid and form a molded resin layer.

A glass fiber wall covering is made by sequential application of a chemical dispersion, a hydrophobic coating to selectively create an image for painted effects, and a second image coating which created plastic volumetric images.
Abstract:
A method of coating an oblong shaped body (8) made of polymer material, which is intended for guiding light in the form of optical signals. In this case, a coating made of polymer material having a lower index of refraction than the shaped body (8) is applied around the shaped body (8). To generate the coating, a coating facility (A) having at least one chamber (1) is used, to which a halogenated gas (4) and/or gas mixture is supplied. The halogenated gas (4) and/or gas mixture is converted into a plasma (6) in the chamber (1) under the effect of microwaves (5) and conducted out of the chamber (1) through a nozzle (7). The shaped body (8) is moved at least one time over its entire length along the coating facility (A) in the region of the nozzle (7) and/or the plasma (6) emitting therefrom and, at the same time, provided with a coating (9) made of a halogenated polymer, which is generated by the incidence of the plasma (6).
Abstract:
The invention concerns a method for restoring the coating of a previously stripped optical fibre, characterised in that it comprises steps which consist in: applying a drop of viscous substance on one end of the fibre (10) stripped zone, at the interface (22) with the remaining initial coating (20), and shaping said drop into a mass (30) centre on the fibre (10) axis, tapering away from the adjacent initial coating (20), before filling up the fibre stripped space with a mass of substance capable of sheathing said fibre (10) again.
