| 20120113595 | Method of Making an Electronic Device - An electronic device includes an electronic component with a mating surface. A thermal interface sheet is attached to the mating surface. A substrate carries the electronic device and includes a face. The electronic component is secured to the substrate with the thermal interface sheet positioned between the mating surface and the face. The mating surface is relatively less flat than the face and the mating surface is relatively smoother than the face. | 05-10-2012 |
| 20120040141 | Dimensionally Stable, Leak-Free Graphite Substrate - A method for preparing resin-impregnated graphite articles, including providing a sheet of compressed particles of exfoliated graphite having two major surfaces; impregnating the sheet with a first resin system to form a resin-impregnated sheet; surface treating the resin-impregnated sheet to form at least one structure on at least one of the major surfaces of the sheet to form a surface treated sheet; and treating the sheet with a second resin system. | 02-16-2012 |
| 20110280275 | Reduced Puffing Needle Coke From Coal Tar Distillate - A reduced puffing needle coke is formed, which includes a reduced nitrogen content within the coke so that the coke particles do not experience as much puffing during the formation of graphitized carbon articles produced from such coke upon heating to graphitization temperatures. | 11-17-2011 |
| 20110280274 | Reduced Puffing Needle Coke From Decant Oil - A reduced puffing needle coke is formed from decant oil, which includes a lesser amount of nitrogen within the coke so that carbon articles produced from such coke experience minimal expansion upon heating to graphitization temperatures. | 11-17-2011 |
| 20110274136 | Reduced Puffing Needle Coke From Coal Tar - A reduced puffing needle coke is formed, which includes a lesser amount of nitrogen within the coke so that carbon articles produced from such coke experience minimal expansion upon heating to graphitization temperatures. | 11-10-2011 |
| 20110027654 | Low Conductivity Carbon Foam For A Battery - A carbon foam battery useful for electrical applications is disclosed which includes a relatively low conductivity low density high porosity carbon foam. | 02-03-2011 |
| 20090032227 | Flexible Graphite Thermal Management Devices - The invention provides to thermal management devices constructed from flexible graphite. In one embodiment, the thermal management device includes a wick structure inside a shell. In certain preferred embodiments, the wick structure is composed of a mass of expanded graphite. In a another embodiment, the shell of the device includes flexible graphite and an optional wick structure. In certain preferred embodiments, the flexible graphite shell is fluid impermeable. The invention further includes methods of making the aforementioned thermal management devices. | 02-05-2009 |
