  • Patent number: 9493523
    Abstract: Provided is an antigen-binding protein prepared merely by a method of in vitro selection using the RNF8-FHA domain, which has no intramolecular disulfide bond and functions in cells as it is. One to four loops extending from the FHA domain are randomized, and a recognition site for a target molecule is artificially created on the FHA domain surface to construct an RNF8-FHA domain library. Using the library, an antigen-binding protein is efficiently selected in vitro.

  • Patent number: 6852646
    Abstract: A method for forming a dielectric film in a PDP includes the steps of: reducing the ambient pressure of an insulating film including a dielectric material before the ambient temperature reaches the reaction temperature of the dielectric material; introducing heated gas to increase the ambient pressure up to the atmospheric pressure while maintaining the ambient temperature at the reaction temperature; and lowering the ambient temperature down to the solidifying temperature of the insulating film while maintaining the atmospheric ambient pressure.

  • Patent number: 6734626
    Abstract: In order to improve the light emitting efficiency of a surface-discharge type color PDP, a sustaining electrode is divided into a plurality of electrodes formed in respective different layers. Lower electrodes 121 and upper electrodes 122 in different layers are formed as electrode pairs, an upper dielectric layer 14 is formed on the upper electrodes 122 in an upper layer to make a dielectric layer on the surface-discharge electrode pair thin to thereby maintain the discharge sustaining voltage low and obtain high light emitting efficiency.
