Patent application number | Description | Published |
20080292844 | Glass article having improved edge - A glass article having an edge of which at least a portion that is ground and subsequently etched to provide a roughened edge. The roughened edge scatters light, thus enabling the glass article to be properly aligned. In some embodiments, the roughened edge also provides a surface having a coefficient of friction that facilitates handling of the glass article. The edge may further include at least one chamfer that may either be polished, so as to be transparent or ground and subsequently etched. | 11-27-2008 |
20080292845 | Glass article having a laser melted surface - A glass article having at least one edge of which at least a portion has been laser melted. The laser melted portion scatters light, thus enabling the glass article to be properly aligned. In some embodiments, the laser melted portion also provides a roughened edge having a coefficient of friction that facilitates handling of the glass article. The laser melted portion is formed by irradiating the peripheral surface with a laser beam to cause localized melting. | 11-27-2008 |
20090035586 | CLEANING METHOD FOR DUV OPTICAL ELEMENTS TO EXTEND THEIR LIFETIME - The invention is directed to a method for cleaning surfaces of optical elements made from metal fluoride single crystals of formula MF | 02-05-2009 |
20100055453 | COLLOIDAL SILICA FINISHING OF METAL FLUORIDE OPTICAL COMPONENTS - The invention is directed to a method for finishing alkaline earth metal fluoride optical components and to the alkaline earth optical elements produced using the method. In particular, in the last polishing step, the method of the invention uses a colloidal silica polishing slurry having containing silica particles having a particle size of <500 nm. Additionally, after colloidal silica polishing, the method using a megasonic cleaning step with a high pH detergent cleaning solution to remove any silica residue on the polished optical component. The optic resulting from use of the method has a polished and unetched surface roughness of less than 0.5 nm; a surface roughness of less then 0.6 nm after polishing and etching; and a step height of less than 6 nm. | 03-04-2010 |
20110256807 | METHOD FOR STRIPPING NITRIDE COATINGS - Methods for stripping partially oxidized nitride wear or release coatings from metal workpieces comprise disrupting surface oxidation layers present on the coatings following use, and causing electrical current to flow from the workpiece and release coating to a counter electrode while the workpiece, release coating and counter electrode are immersed in an aqueous alkaline electrolyte solution. | 10-20-2011 |
20120145308 | METHODS FOR ANODIC BONDING MATERIAL LAYERS TO ONE ANOTHER AND RESULTANT APPARATUS - Methods and apparatus provide for: disposing an intermediate layer formed from at least one of: a metal, a conductive oxide, and combined layers of the metal and the conductive oxide, on one of a first material layer and a second material layer; and coupling the first and second material layers together via an anodic bond between the intermediate layer and the other of the first and second material layers. | 06-14-2012 |
20120210749 | ION EXCHANGE USING NITRATES AND NITRITES TO PREVENT OPTICAL DEGRADATION OF GLASS - A method of chemically strengthening a glass article having an antireflective coating in which the reflectance of the coating is not significantly degraded by chemical strengthening. The glass article having the antireflective coating is strengthened using an ion exchange medium that comprises potassium nitrate and at least about 5 wt % potassium nitrite. Also provided are a glass article having an antireflective surface that is not degraded by such ion exchange and an ion exchange medium comprising potassium nitrate and at least about 5 wt % potassium nitrite. | 08-23-2012 |
20120280373 | ACTIVE ELECTRONICS ON STRENGTHENED GLASS WITH ALKALI BARRIER - Articles are described utilizing strengthened glass substrates, for example, ion-exchanged glass substrates, with oxide or nitride containing alkali barrier layers and with semiconductor devices which may be sensitive to alkali migration are described along with methods for making the articles. | 11-08-2012 |
20130125590 | RECONDITIONING GLASS-FORMING MOLDS - Glass-forming molds comprising titanium aluminum nitride glass release coatings are reconditioned with aqueous mineral acid solutions comprising fluoride and phosphate ions to provide molds with restored glass release characteristics without recoating, permitting the molding of glass articles from aggressive ion-exchange-strengthenable high-alkali aluminosilicate glasses at high temperatures over extended mold service intervals. | 05-23-2013 |
20130221510 | METHODS FOR BONDING MATERIAL LAYERS TO ONE ANOTHER AND RESULTANT APPARATUS - Methods and apparatus provide for a structure, including: a first glass material layer; and a second material layer bonded to the first glass material layer via bonding material, where the bonding material is formed from one of glass frit material, ceramic frit material, glass ceramic frit material, and metal paste, which has been melted and cured. | 08-29-2013 |
