20090298669 | GLASS PLATE FOR DISPLAY DEVICES - To provide a glass plate for display devices wherein without carrying out a post treatment, the depth of a compression stress layer is increased, while the surface compression stress is prevented from being excess only by chemical tempering. | 12-03-2009 |
20110071012 | GLASS AND CHEMICALLY TEMPERED GLASS - Glass comprising, as represented by mole percentage based on the following oxides, from 50 to 75% of SiO | 03-24-2011 |
20110091704 | GLASS PLATE FOR DISPLAY DEVICE, PLATE GLASS FOR DISPLAY DEVICE AND PRODUCTION PROCESS THEREOF - A process for producing a plate glass for a display device having a thickness of at most 1.5 mm by a float process, wherein the plate glass comprises, as represented by mole percentage based on the following oxides, from 67 to 75% of SiO | 04-21-2011 |
20120297829 | METHOD FOR PRODUCING CHEMICALLY TEMPERED GLASS - To provide a method for producing chemically tempered glass, whereby frequency of replacement of the molten salt can be reduced. A method for producing chemically tempered glass, which comprises repeating ion exchange treatment of immersing glass in a molten salt, wherein the glass comprises, as represented by mole percentage, from 61 to 77% of SiO | 11-29-2012 |
20130093312 | PLASMA DISPLAY DEVICE - To provide a plasma display device whereby it is possible to improve the image quality and at the same time to reduce warpage of a thin cover glass plate having a large area. A plasma display device | 04-18-2013 |
20130209773 | GLASS FOR CHEMICAL TEMPERING, CHEMICALLY TEMPERED GLASS, AND GLASS PLATE FOR DISPLAY DEVICE - To provide glass to be used for chemically tempered glass, of which the strength is less likely to be reduced even when indentations are formed thereon. Glass for chemical tempering, which comprises, as represented by mole percentage based on oxides, from 62 to 68% of SiO | 08-15-2013 |
20130269392 | PROCESS FOR PRODUCING CHEMICALLY TEMPERED GLASS - To provide a process for producing a chemically tempered glass whereby it is possible to increase the surface compressive stress. A process for producing a chemically tempered glass, which comprises holding a glass at a temperature of at least the strain point minus 40° C. and at most the strain point plus 70° C. for at least 30 minutes for heat treatment, and thereafter, immersing it in a molten salt for ion exchange without allowing the temperature to exceed the strain point plus 70° C. | 10-17-2013 |
20130302617 | GLASS FOR CHEMICAL TEMPERING AND GLASS PLATE FOR DISPLAY DEVICE - To provide glass to be used for chemically tempered glass which is hardly broken even when flawed. | 11-14-2013 |
