摘要:
A method for processing a transparent workpiece including directing a laser beam in a first orientation along a first beam pathway where a first portion of the laser beam includes a first laser beam focal line and generates an induced absorption to produce a first defect segment within the transparent workpiece. The method further includes adjusting the laser beam to a second orientation along a second beam pathway where a second portion of the laser beam includes a second laser beam focal line and generates the induced absorption to produce a second defect segment within the transparent workpiece. Each of the first and second laser beam focal lines include a circular angular spectrum within the transparent workpiece; and at least one of the laser beam focal lines include an internal focal line angle of greater than 10° relative to a plane orthogonal to the impingement surface at the impingement location.

A method of manufacturing a reinforced plate glass by which glass surface strength is sufficiently increased, and a stable quality reinforced plate glass is manufactured at high production efficiency. The reinforced plate glass is formed of an inorganic oxide glass, and is provided with a compression stress layer by chemical reinforcement on plate surfaces opposed to each other in a plate thickness direction. Plate end faces have regions where a compression stress is formed and regions where no compression stress is formed.

A moil crack-off system for a funnel is provided, wherein a pick-up apparatus is arranged intersectionally above a conveyor that is extended from the shaping process of the funnel, and a pair of ware transfers are arranged in parallel on either side of the conveyor. The funnel that is riding on the conveyor is absorbed at a predetermined position by vacuum pads that are loaded on the carriers of the pick-up apparatus, and is moved in a three-dimensional manner to either of the ware transfers. The ware transfers deliver the three-dimensionally moved funnel to a scoring part and a two-step fire polishing part, which are arranged within the ware transfers, so that the moil of the funnel is cracked off automatically.

摘要:
A fluid for use in a glass cutting operation contains two portions. A first portion of the fluid is a highly volatile, nonresidue forming, cutting tool lubricant. The second portion of the fluid is a non-volatile material either dissolved in or carried by the tool lubricant. The non-volatile material is one which forms an encapsulating film along a score placed on a glass surface by a glass cutting tool. This film binds any wing chips to the edge of the score to prevent spalling.
