  • Patent number: 7908380
    Abstract: A method to limit active sessions connecting user access to a computer network is presented. First, a request to initiate a new user session in the computer network is authenticated. The authentication is operatively conducted within a single sign-on provider. A session quota is then determined through a session quota logic of the single sign-on provider with the session quota logic retrieving a stored session quota. Then the number of active sessions is compared with the determined session quota. The determined session quota is enforced though a session quota enforcement logic of the SSO provider.

  • Publication number: 20110056244
    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.

  • Publication number: 20110059610
    Abstract: A method of backside metal process for semiconductor electronic devices, particularly of using an electroless plating for depositing a metal seed layer for the plated backside metal film. The backside of a semiconductor wafer, with electronic devices already fabricated on the front side, is first coated with a thin metal seed layer by electroless plating. Then, the backside metal layer, such as a gold layer or a copper layer, is coated on the metal seed layer. The metal seed layer not only increases the adhesion between the front side metal layer and the backside metal layer through backside via holes, but also prevents metal peeling after subsequent fabrication processes. This is helpful for increasing the reliability of device performances. Suitable materials for the metal seed layer includes Pd, Au, Ni, Ag, Co, Cr, Cu, Pt, or their alloys, such as NiP, NiB, AuSn, Pt—Rh and the likes.

  • Patent number: 7776976
    Abstract: This invention puts forward a process of preparing butyl rubber. High gravity devices are used as polymerization reactor. The mixture of isomonoolefin and conjugated diolefin monomers and the diluent, and the mixture of the initiator and diluent are pumped at a certain ratio into a high-gravity reactor to conduct cationic polymerization in the high-gravity environment. After polymerization, the monomers and the diluent are removed from the product to obtain butyl rubber polymers with number-average molecular weight of 80000˜300000 and molecular weight distribution index of 1.9˜3.6. The high gravity polymerization method of this invention can tremendously intensify micro-mixing, mass transfer and heat transfer in the reaction. Compared to the conventional stirred polymerization method, this invention features small reactor volume, at least 30-fold shorter residence time of substances in the high gravity reactor, low cost, low energy consumption and high production efficiency.
