| 20090075802 | GLASS-CERAMIC SEALS FOR USE IN SOLID OXIDE FUEL CELLS - The invention is directed to highly crystalline, frit-sintered glass-ceramic materials and seals made using them that are suitable for solid oxide fuel cell applications. The seals have a coefficient of thermal expansion in the range of 70-130×10 | 03-19-2009 |
| 20090101924 | Gallium nitride semiconductor device on SOI and process for making same - Methods and apparatus for producing a gallium nitride semiconductor on insulator structure include: bonding a single crystal silicon layer to a transparent substrate; and growing a single crystal gallium nitride layer on the single crystal silicon layer. | 04-23-2009 |
| 20090274869 | COLORED MACHINABLE GLASS-CERAMICS - The invention relates to opaque, colored glass-ceramic articles and to the production of opaque, colored glass-ceramic articles which can be readily formed to a desired shape using standard metal-working tools. The glass-ceramic material used to make such articles contains mica crystals as the predominant phase. The desired color is obtained through the addition of a colorant system to the precursor glass. In a particular embodiment the invention is directed to a black glass-ceramic article, the black color being obtained by the addition of iron oxides in levels as high as 20 wt %, which can yield a glass-ceramic having an iron-rice mica phase and/or a glass ceramic having an iron-rich mica phase plus an iron oxide phase. | 11-05-2009 |
| 20100047521 | DURABLE GLASS HOUSINGS/ENCLOSURES FOR ELECTRONIC DEVICES - The invention relates to glass articles suitable for use as electronic device housing/enclosure or protective cover which comprise a glass material. Particularly, a housing/enclosure/cover comprising an ion-exchanged glass exhibiting the following attributes (1) radio, and microwave frequency transparency, as defined by a loss tangent of less than 0.03 and at a frequency range of between 15 MHz to 3.0 GHz; (2) infrared transparency; (3) a fracture toughness of greater than 0.6 MPa·m | 02-25-2010 |
| 20100275767 | MULTI-HIT CAPABLE TRANSPARENT, MULTI-STACK ARMOR SYSTEM - A transparent armor laminate system includes a plurality of sub-stacks separated by an interlayer. The sub-stacks include a plurality of layers including a glass ceramic front strike-face layer, a backing layer comprising a spall-resistant material, and at least one glass layer laminated between the strike-face and backing layers. The interlayer isolates cracks between sub-stacks, and may include an isolating material such as a polymer, gas, or liquid. The laminate system offers improved performance with reduced weight over conventional all-glass or all-glass-ceramic transparent armors. | 11-04-2010 |
| 20110088541 | TRANSPARENT ARMOUR HAVING IMPROVED BALLISTIC PROPERTIES - This disclosure teaches the use of low density, “open”-structure glasses as backing glasses, behind glass-ceramic strike-faces, in transparent armor composite windows. These low density “open-structure’ glasses are sometimes referred to as “anomalous” glasses. For transparent armor applications both silica, including fused silica, and borosilicate glasses can be used as backing glass. These backing glasses provide improved ballistics performance over that of standard commercial soda lime backing glass. These glasses should be used either in their as-formed state (e.g. float surfaces) or should be finished using a process designed for minimizing sub-surface damage. | 04-21-2011 |
| 20110092353 | DURABLE GLASS-CERAMIC HOUSINGS/ENCLOSURES FOR ELECTRONIC DEVICE - The invention relates glass ceramic articles suitable for use as electronic device housing or enclosures which comprise a glass-ceramic material. Particularly, a glass-ceramic article housing/enclosure comprising a glass-ceramic material exhibiting both radio and microwave frequency transparency, as defined by a loss tangent of less than 0.5 and at a frequency range of between 15 MHz to 3.0 GHz, a fracture toughness of greater than 1.5 MPa·m | 04-21-2011 |
