  • Publication number: 20070090233
    Abstract: A stand for an image display device includes a supporting member that can support an image display device, a rear base is rotatably connected to the supporting member, and a front base that is connected to the rear base. The front base is rotatable with respect to the rear base in the same direction as the rear base is rotatable with respect to the supporting member such that the front base is foldable to a rear side of the image display device.

  • Publication number: 20060063012
    Abstract: A method for preparing a dielectric film. According to the method, a dielectric film is prepared by depositing a dual organic siloxane precursor on a wafer by plasma enhanced chemical vapor deposition (PECVD). Since a dielectric film prepared by the method has a low dielectric constant and shows superior physical properties, such as elastic modulus and hardness, it can be useful as an interlayer dielectric film for a semiconductor device for dual damascene copper interconnects or as a passivation layer for semiconductor and display devices.

  • Publication number: 20050259187
    Abstract: A coupler structure for a CRT projection TV includes a coupler as a component of a CRT assembly positioned in the CRT projection TV, made up of a housing having an opening formed at the center thereof and a containing space formed therein with a predetermined depth and an extension extending outwardly from an upper edge of the housing with a coupling hole formed on the periphery of the extension. In the present invention, fluid interruption steps are formed with a predetermined height on the edge of the extension adjacent to the convex portion of the housing, and are formed around the coupling hole of the extension, respectively, in such a manner that electronic devices around the coupler are not damaged even if some of the cooling fluid which fills the containing space of the housing leaks out due to physical impact.

  • Patent number: 6677376
    Abstract: The invention relates to non-peptidic compounds that possess bioactive properties, such as the ability to protect neuronal cells from otherwise lethal treatments or the ability to promote the growth or regeneration of neuronal cells. In part, the invention provides compounds that interact with or bind to a cyclophilin and compounds that have activity towards neuronal cells. Methods for using the compounds, such as administering them to cells or animals or using them to treat neurodegenerative conditions, are specifically included.
