| 20100013114 | METHOD OF FORMING - The present invention relates to a method of using non-macrogelled polymer-solvent combinations to form devices, in particular medical devices and/or cosmetic devices, more specifically contact lenses. The method of using polymer solvent combinations is suitable for forming useful 3D dimensionally stable structures which may include curved surfaces, which may be significantly different to those curved surfaces achieved by using simple meniscus effects. | 01-21-2010 |
| 20100320627 | Optical film, method for producing the same and polarizing plate using the same - A method for producing an optical film comprising the steps of: (i) melt casting a cellulose ester resin or a cycloolefin resin by extruding melt of the cellulose ester resin or the cycloolefin resin from a die onto a roll-shaped cooling drum; (ii) cooling and solidifying the extruded melt to form a film; (iii) stretching the film in a lateral direction of the film; and (iv) winding the film in a roll, wherein the cooling drum has plural regions divided predeterminedly in an axis direction of the cooling drum, a temperature of each region being independently controlled. | 12-23-2010 |
| 20110156294 | METHOD OF MANUFACTURING BRIGHTNESS ENHANCEMENT FILM AND ROLLER USED THEREIN - A method of manufacturing a brightness enhancement film utilizes a roller with an outer surface and a plurality of slot portions formed thereon by sandblasting and includes heating a substrate, rolling the textured roller on to the substrate such that the slot portions imprint the substrate and form a plurality of protrusions thereon, and cutting the substrate which has been imprinted to provide a brightness enhancement film. | 06-30-2011 |
| 20110156295 | EMBOSSING ASSEMBLY, MANUFACTURING METHOD THEREOF, AND EMBOSSING METHOD USING THE SAME - A method of manufacturing a brightness enhancement film includes the following: providing a embossing substrate, providing a first embossing assembly including a roller and an embossing layer applied on the roller, which is formed by electroforming and includes protruding micro-structures formed on the outer surface of the embossing layer, rolling the embossing layer onto the embossing substrate, and embossing the recessed micro-structures on a surface of the embossing substrate. | 06-30-2011 |
| 20110241234 | FABRICATION PROCESS FOR MASTERING IMAGING LENS ARRAYS - A process and method for fabricating a master lens array for use in the manufacture of duplicate lens arrays is provided. The fabrication methods provided herein are capable of maximizing the quality of the master lens array in an efficient and cost effective manner, thereby reducing the propagation of errors in the lenses formed using the master lens array. | 10-06-2011 |
| 20130193597 | REFLECTOR MOLDING APPARATUSES AND METHODS THEREOF - A reflector molding apparatus includes two pressure rollers with pressure surfaces of the rollers comprising convex teeth and concave teeth in mesh. The reflection film is put on the aluminum sheet as the unmolded material. The unmolded material goes to the pressure surfaces in mesh and is molded to be a reflector. The surface of the resulting reflector is corrugated shaped because of the pressure of the rollers. The shape of the reflector changes with the pressure surface of the rollers. | 08-01-2013 |
| 20130313733 | METHOD OF MAKING A FULLY POLYMERIZED UV BLOCKING SILICONE HYDROGEL LENS - A method of making a substantially fully copolymerized UV blocking hydrogel lens demonstrating sufficient blocking of UV light to meet at least FDA Class II specifications for UV blocking formed from a reaction mixture comprising at least NVP and one other comonomer and a free-radical polymerizable, substituted or unsubstituted, Bis O-hydroxy benzophenone is provided herein. | 11-28-2013 |
