| 20120129679 | GLASS COMPOSITION AND PROCESS FOR PRODUCING GLASS COMPOSITION - A glass composition which is reduced in the amount of residual bubbles and is produced using smaller amounts of an environmentally unfriendly component such as arsenic oxide and antimony oxide. This glass composition contains, in terms of mass %: 40-70% SiO | 05-24-2012 |
| 20120125050 | METHOD FOR MANUFACTURING GLASS PLATE - A method for manufacturing a glass plate includes preparing an accommodating part made of platinum or a platinum alloy, fining molten glass of a melted feedstock, stirring and homogenizing the molten glass, and supplying the molten glass to a forming apparatus. The fining the molten glass includes causing gas bubbles to float up and out from the molten glass, and causing absorption of the gas component in the molten glass and eliminating gas bubbles. The water vapor partial pressure of an atmosphere in the causing the gas bubbles is lower than the water vapor partial pressure in at least a portion of the causing the absorption of the gas component. A boundary between the causing the gas bubbles and the causing the absorption of the gas component is a temperature lower than the maximum temperature by 30° C. or more after the molten glass has reached the maximum temperature. | 05-24-2012 |
| 20120083401 | COVER GLASS AND METHOD FOR PRODUCING COVER GLASS - The disclosed cover glass is produced by etching a glass substrate that has been formed by a down-drawing process, and chemically strengthening the glass substrate to provide the glass substrate with a compressive-stress layer on the principal surfaces thereof. The glass substrate contains, as components thereof, 50% to 70% by mass of SiO | 04-05-2012 |
| 20110207594 | GLASS COMPOSITION - A glass composition which is reduced in the amount of residual bubbles and is produced using smaller amounts of an environmentally unfriendly component such as arsenic oxide and antimony oxide. This glass composition comprises, in terms of mass %; 40-70% SiO | 08-25-2011 |
| 20110143908 | GLASS COMPOSITION, GLASS SUBSTRATE FOR FLAT PANEL DISPLAY USING THE SAME, FLAT PANEL DISPLAY, AND METHOD FOR PRODUCING GLASS SUBSTRATE FOR FLAT PANEL DISPLAY - Provided is a glass composition suitable for a glass substrate for a flat panel display such as a liquid crystal display. This glass composition has high thermal stability, and is substantially free of BaO but has a low devitrification temperature. It is suitable for the production of a glass substrate by a downdraw process. This glass composition contains, in terms of mass %; 54 to 62% of SiO | 06-16-2011 |
| 20100298112 | Glass substrate for display and display - A glass substrate for a display, which is formed of a glass having a light weight and having high refinability with decreasing environmental burdens, the glass comprising, by mass %, 50 to 70% of SiO | 11-25-2010 |
| 20100273634 | GLASS COMPOSITION AND PROCESS FOR PRODUCING GLASS COMPOSITION - A glass composition which is reduced in the amount of residual bubbles and is produced using smaller amounts of an environmentally unfriendly component such as arsenic oxide and antimony oxide. This glass composition contains, in terms of mass %: 40-70% SiO | 10-28-2010 |
