| 20100126222 | METHOD AND APPARATUS FOR FORMING AND CUTTING A SHAPED ARTICLE FROM A SHEET OF MATERIAL - An apparatus for forming shaped articles from a sheet of material includes a first mold having a mold surface and a network of gutters formed in the mold surface. The network of gutters has a network gutter profile and defines an array of islands on which an array of bumps is formed. Each of the bumps has a surface with a shaped profile. The apparatus also includes a second adapted for positioning on the mold surface. The second mold has a network of protuberances defining a plurality of cavities. Each of the cavities is sized to overlap one of the bumps of the first mold. The network of protuberances has a network protuberance profile complementary to the network gutter profile. | 05-27-2010 |
| 20100212361 | METHOD FOR SCORING A SHEET OF BRITTLE MATERIAL - A method of cutting glass that prevents uncontrolled crack propagation when high background stress is present, either in the form of thermal residual stress, external mechanical stress or a combination thereof. The method includes masking an edge of the glass by blocking the beam using highly reflective or absorptive material located near the glass surface, or deposited on the surface in a form of a thin film (or highly reflective paint) to prevent uncontrolled crack initiation and propagation starting from the glass edge. The initiation of the laser scoring is located at a predetermined distance from the glass edge. Yet another aspect of the invention embodies stopping propagation of the vent at the exiting end of the score line. | 08-26-2010 |
| 20110030424 | METHOD OF MANUFACTURING SUBSTRATE FOR MAGNETIC RECORDING MEDIUM - A method of manufacturing a substrate for a magnetic recording medium that is capable of manufacturing a magnetic recording medium substrate having no warping and superior surface smoothness at a high level of productivity and at low cost. The method of manufacturing a substrate for a magnetic recording medium according to the present invention includes a thin glass sheet formation step of heating and softening a sheet-like glass base material ( | 02-10-2011 |
| 20110113830 | METHOD FOR CUTTING A BRITTLE MATERIAL - A method of scoring and/or separating a brittle material is described comprising heating a surface of the brittle material along a predetermined path with a laser, then quenching the heated surface with a stream of cooling liquid, such as water, formed by a nozzle. The portion of the cooling stream impinging on the surface of the brittle material is a substantially columnar flow. | 05-19-2011 |
| 20120006063 | METHOD OF MANUFACTURING GLASS SUBSTRATE - A method includes forming a glass ribbon by heating and softening a glass plate preform and drawing the glass plate preform to a predetermined thickness in a heating furnace; and performing coring on the glass ribbon in order to form circular substrates in a straight line along a longitudinal direction of the glass ribbon. | 01-12-2012 |
| 20120017642 | CLEAVING METHOD FOR A GLASS FILM, MANUFACTURING METHOD FOR A GLASS ROLL, AND CLEAVING APPARATUS FOR A GLASS FILM - In a cleaving apparatus ( | 01-26-2012 |
| 20130000356 | GLASS BENDING METHOD AND APPARATUS - A sag-bending glass mold for creating a partial parabolic-curved glass sheet is disclosed. The glass mold comprises a glass-support surface having a cross-sectional profile of varying height. The cross-sectional profile has a first portion with profile of a non-parabolic, linear-square root composite shape. A method for forming a partial parabolic glass sheet is also disclosed. The method comprises positioning a planar glass sheet on a sag-bending mold having a linear-square root composite shape and deforming the glass sheet to follow the linear-square root composite shape of the sag-bending mold. | 01-03-2013 |
