  • Publication number: 20120213949
    Abstract: The invention relates to a method for producing a transparent indium tin oxide conductive layer on a substrate. The method involves using a target having a low indium-to-tin ratio in a low temperature manufacturing process (less than 200° C.), and introducing a plasma gas and a reaction gas into the reaction chamber to allow sputtering of an indium tin oxide layer on the substrate under a low oxygen environment, followed by subjecting the sputtered substrate to a heat treatment at 150˜200° C. for 60˜90 minutes. The indium tin oxide layer thus produced will crystallize completely and have the advantageous properties of low surface resistance and high uniformity.

  • Patent number: 8245535
    Abstract: A method of strengthening glass plate is provided. A plasma treating process is performed on a glass plate so that a surface pore variation of the glass plate after the plasma treating process is reduced relative to the surface pore variation of the glass plate before the plasma treating process, wherein the surface pore variation is a variation degree of surface pores in different unit areas of the glass plate. In the mean time, a melted network crosslinking structure is formed on the surface of the glass plate. Based on the above-mentioned mechanisms, the glass plate is strengthened. The plasma treating process is conducive to strengthen the glass plate whether the plasma treating process is performed before or after the conventional chemical strengthening process.

  • Patent number: 8051179
    Abstract: A distributed session failover mechanism is disclosed for facilitating the replication and retrieval of session information. A first server, in a trusted network, providing a single sign-on (SSO) solution, stores session information pertaining to a particular client requesting services associated with the server. In order to provide session failover, the first server sends a copy of the session information to a bus mechanism, which is connected to one or more persistent repositories. When a second server attempts to validate the client, the second server may discover that the first server failed. The second server then requests a copy of the session information pertaining to the client from the bus mechanism. The bus mechanism retrieves the copy from a persistent repository and provides the copy to the second server.
