| 20080308865 | SEMICONDUCTOR DEVICE AND METHOD FOR MANUFACTURING THE SAME - A semiconductor device includes a structure of a gate electrode/a high-k dielectric insulating film containing aluminum and having a dielectric constant greater than that of a silicon oxide film/the silicon oxide film/a silicon substrate, and is provided with a diffusion layer formed by diffusing an aluminum atom or an aluminum ion to the silicon oxide film or an interface between the silicon oxide film and the silicon substrate by a heat treatment. A laminated film or a mixed film of hafnium oxide and aluminum oxide having a ratio of hafnium and aluminum ranging from about 2:8 to 8:2 is used as the high-k dielectric film. The heat treatment is performed at any temperature from about 500 to 1000° C. for any period of time from about 1 to 100 seconds. | 12-18-2008 |
| 20100270749 | MECHANICAL SEAL DEVICE AND TANDEM SEAL DEVICE - The present invention provides a mechanical seal device for obtaining appropriate sliding properties under any conditions, such as a pressure of seal is low or high. In the present invention, both first grooves | 10-28-2010 |
| 20100327533 | SHAFT SEALING DEVICE - A shaft sealing device in which a load acting on a sliding section of the device is reduced to extend the life of the device and which permits no leakage of fluid in a machine to an atmospheric air to eliminate the need of recovery of the fluid. The shaft sealing device has seals arranged in three stages in the axial direction between a seal case and a rotating shaft passed through the inner periphery of the seal case. Of the seals of the three stages, a first-stage seal on the machine's inner side and a third-stage seal on the machine's outer side have a contact type mechanical seal structure in which a rotational sealing element and a stationary sealing element are in close sliding contact with each other. Further, of the seals of the three stages, the intermediate second-stage seal has a contactless mechanical seal structure in which a rotational sealing element and a stationary sealing element are kept by dynamic pressure so as not to be in contact with each other. A high-pressure sealing liquid is supplied by the pressure of fluid in the machine to an annular space surrounded by that portion of the seal case which extends from the first-stage seal to the second-stage seal. | 12-30-2010 |

| 20100171420 | PLASMA DISPLAY PANEL AND METHOD FOR MANUFACTURING THE SAME - A plasma display panel has a plurality of pairs of display electrodes, dielectric layer, and protective layer disposed on front glass substrate. Protective layer is formed of nano crystal particles, and the average particle diameter of the nano crystal particles is in the range of 10 nm to 100 nm. With this structure, in the plasma display panel, front glass substrate has a sufficient strength and occurrence of panel cracks is reduced. | 07-08-2010 |
| 20100181908 | FLAT DISPLAY - Disclosed here is a flat display having a pair of glass substrates and a sealing member applied on the periphery of the glass substrates. The glass substrates are oppositely disposed to each other at intervals therebetween. The glass substrates contain silicon as a component, while the sealing member contains bismuth. A protection layer and an insulating layer as an intermediate layer, which has a silicon-content lower than the glass substrates, are formed on the interface between the glass substrates and the sealing member. The structure above reinforces bonding strength of the sealing section, providing a highly reliable flat display. | 07-22-2010 |
