摘要： Methods for controlling the bow (shape) of a vertical glass ribbon (13) produced by a downdraw process are provided. The methods involve passing the ribbon (13) through a gas-filled vertical enclosure (23), e.g., a draw tower, whose bottom (31) is open to the atmosphere. The ribbon (13) acts as a septum that divides the enclosure's internal volume (29) into a first sub-volume (25) and a second sub-volume (27). Using the stack effect, a positive pressure difference is produced between the first sub-volume (25) and the second sub-volume (27) along at least a portion of the length of the enclosure (the DDZ). The edges of the ribbon (13) are constrained so that they do not move into the second sub-volume (27) over at least the DDZ. As a result, the ribbon bows with its concavity facing the first sub-volume (25) and its convexity facing the second sub-volume (27).

摘要： In the formation of sheet glass by the overflow downdraw process, the width of usable sheet glass is maximized by downwardly flowing edge portions of the sheet over web-like members and thereafter over extensions which intersect with and are downwardly inclined relative to the web-like members to thin edge portions of the glass flow and maintain sheet width. The extension members are preferably removably attached to the web-like members, greatly facilitating replacement of the more easily damaged extension members.

摘要： A method is disclosed for the planarization of a semiconductor device structure by a two stage planarization process which comprises: applying a dielectric layer over a first conductive layer, spin coating an organic layer onto the first dielectric layer, etching the device in a plasma etching process to substantially remove the organic planarization layer, then etching the device in a plasma etching process which etches the exposed dielectric layer to substantially remove all of it, removing the remaining organic planarization layer, followed by the application of a second dielectric layer under bias sputter deposition conditions. The bias sputter deposition fills trenches and eliminates peaks in the remaining first dielectric layer as it builds up the second dielectric layer. The process planarizes the dielectric layer without thickness variations dependent upon conductor layer pattern density.

摘要： In a process for continuously producing a light conducting glass fiber wherein the refractive index in a plane perpendicular to the optical axis of the glass fiber is so distributed that it continuously decreases outward from a certain value at the center toward the peripheral portion, a first kind of glass containing ions having a greater degree of contribution to the refractive index is drawn, in molten state from a central orifice to form the core portion of the glass fiber, and another kind of melted glass containing ions having less contribution to the refractive index is drawn from a second orifice to form an outer coating layer of the glass fiber, the tip of the first central orifice being located at a retracted position compared to that of the second orifice with respect to the drawn direction of the melted glasses, whereby thermal mutual diffusion of these ions is caused to occur through a boundary surface between two kinds of glasses located mainly in the distance portion between the tips.

摘要： Methods for separating glass articles from glass substrate sheets are described herein. In one embodiment, a method includes focusing a laser beam on at least one surface of the glass substrate sheet such that the laser beam has an asymmetrical intensity distribution at the at least one surface of the glass substrate sheet. The method further includes translating the laser beam on the at least one surface of the glass substrate sheet along a desired groove line to form at least one groove on the at least one surface of the glass substrate sheet. The at least one groove extends partially through a thickness of the glass substrate sheet along the desired groove line and has bevelled or chamfered walls. The glass article may be separated from the glass substrate sheet along the at least one groove.
