| 20080216513 | Method for the Regeneration of a Worn Quartz Glass Jig - To provide a technique with which a quartz glass jig and a doped quartz glass jig are regenerated by completely removing the impurities which are attached to the surface and the impurities which have diffused into the interior from quartz glass jigs which have been used in semiconductor production processes and then carrying out working repair and removing the contamination from the working processes as well. After use, the impurities are removed from the aforementioned quartz glass jigs in the said purification treatment process which includes a purification treatment process in which the quartz glass jigs are subjected to a purification treatment in a gaseous atmosphere which includes a halogen element at a temperature within the region above a prescribed temperature. | 09-11-2008 |
| 20110138857 | BONDED GLASS CUTTING METHOD, PACKAGE MANUFACTURING METHOD, PACKAGE, PIEZOELECTRIC VIBRATOR, OSCILLATOR, ELECTRONIC DEVICE, AND ATOMIC TIMEPIECE - To provide a bonded glass cutting method whereby it is possible to suppress an occurrence of a crush or chipping when bonded glass is cut, and cut the bonded glass into pieces of a predetermined size, a package manufacturing method, a package, a piezoelectric vibrator, an oscillator, an electronic device, and an atomic timepiece. A bonded glass cutting method includes a scribing step, which irradiates a lid substrate wafer with a laser beam with a wavelength absorbed by a wafer bonded body along outlines, thus forming scribe lines on the lid substrate wafer, and a breaking step which, by cutting the wafer bonded body by applying a fracture stress to the scribe lines, dices the wafer bonded body into a plurality of piezoelectric vibrators, wherein a cutting step is carried out in a condition in which the wafer bonded body is placed on silicon rubber, and an outside end face of the lid substrate wafer is caused to face the silicon rubber. | 06-16-2011 |
| 20110203319 | METHOD OF RECYCLING MIXED COLOR CULLET USING COPPER OXIDE - Green glass content of mixed color glass cullet is selectively decolorized by using copper oxide and is used as an input component in a conventional glass production process. To determine how much copper oxide to add, the weight percent of green glass in the provided glass cullet supply is determined and an effective amount of copper oxide to, at least partially, decolorize the green glass is determined wherein an effective amount is determined using a non-linear inverse prediction model between the weight percent of green glass or chromium and/or iron content and the copper oxide. The amount of copper oxide is thus non-linearly adjusted for increasing levels of green glass in the glass batch. To compensate for the darkening of the glass by the additional copper oxide, the redox of the glass may be made slightly less reducing as the amount of chrome and copper is increased. | 08-25-2011 |
| 20130139551 | System And Method For Laser-Based, Non-Evaporative Repair Of Damage Sites In The Surfaces Of Fused Silica Optics - A method for repairing a damage site on a surface of an optical material is disclosed. The method may involve focusing an Infrared (IR) laser beam having a predetermined wavelength, with a predetermined beam power, to a predetermined full width (“F/W”) 1/e | 06-06-2013 |
| 20130291591 | METHOD AND EQUIPMENT FOR RECOVERING WASTE FROM CONTINUOUS FIBRE PRODUCTION INSTALLATIONS AND FOR DIRECTLY RECYCLING THE RESULTING GLASS - Method for treating continuous fibreglass filament waste, including comminuting the waste to obtain comminuted fibre pieces of predetermined size; continuously feeding a feedstock of comminuted fibre pieces to a heat treatment; and heating the feedstock of comminuted fibre pieces to cause, in succession, the elimination of any moisture content, the evaporation of volatile components of an organic coating of the continuous fibre, and the combustion of residual components of the organic coating. The feedstock of comminuted fibre pieces is fed to the heat treatment as a web of material. At least the combustion of residual components of the organic coating takes place in a tunnel furnace including heat sources provided above and below the web of material. During the heat treatment, the feedstock of comminuted fibre pieces moves continuously forward, and is brought, in a progressively rising way, from a starting temperature to a final heating temperature greater than the softening point of fibreglass. | 11-07-2013 |
| 20140165652 | CUTTING METHOD FOR REINFORCED GLASS PLATE AND REINFORCED GLASS PLATE CUTTING DEVICE - The invention relates to a method for cutting a strengthened glass sheet in which, when a strengthened glass sheet | 06-19-2014 |
| 20140311184 | METHOD FOR RECYCLING MATERIAL WHEN MAKING A MINERAL MELT - The present invention concerns a method of making a mineral melt by burning combustible material in the presence of inorganic particulate material and thereby forming a melt, comprising injecting fuel, particulate mineral material and combustion gas into a circulating combustion chamber ( | 10-23-2014 |
| 20150013386 | BATCH-CHARGING MACHINE WITH REMOVABLE HEAD FOR SUBMERGED BATCH-CHARGING - A batch charger for charging batch materials into a glass melting furnace at a level located below the level of the molten glass, including: a body including a barrel and a mechanical system for conveying batch materials, the mechanical system being housed in the barrel; and a head removably fastened to an end of the barrel, and including a slide gate damper, and a tubular connecting part fastened to the slide gate damper and configured to be at least partially inserted into a charging orifice provided in a wall of a tank of the furnace, the slide gate damper and the connecting part including a system of internal ducts that can be connected to a source of coolant. A melting installation and a process can use such a batch charger. | 01-15-2015 |
