  • Publication number: 20120039874
    Abstract: Immunization of human antibody-producing transgenic mice, which have been created using genetic engineering techniques, with AILIM molecule as an antigen resulted in various human monoclonal antibodies capable of binding to AILIM and capable of controlling a variety of biological reactions (for example, cell proliferation, cytokine production, immune cytolysis, cell death, induction of ADCC, etc.) associated with AILIM-mediated costimulatory signal (secondary signal) transduction. Furthermore, it has been revealed that the human monoclonal antibody is effective to treat and prevent various diseases associated with AILIM-mediated costimulatory signal transduction, being capable of inhibiting the onset and/or advancement of the diseases.

  • Patent number: 8046276
    Abstract: A receiving section receives a supply request for product from a terminal set up at a shop or a terminal used by a client. A first determination processing section determines whether a product in stock can be reserved for an order. A first reserve processing section reserves the product in stock for the order when the first determination processing section determines that the product can be reserved. A second determination processing section determines whether a semifinished product necessary for manufacturing a final product can be reserved when the first determination processing section determines that the product reserve is inadequate. A second reserve processing section reserves the semifinished product for the order when the second determination processing section determines that the semifinished product can be reserved.

  • Patent number: 7790557
    Abstract: Stress is exerted to the SiC crystal in the region, in which the carriers of a SiC semiconductor device flow, to change the crystal lattice intervals of the SiC crystal. Since the degeneration of the conduction bands in the bottoms thereof is dissolved, since the inter-band scattering is prevented from causing, and since the effective electron mass is reduced due to the crystal lattice interval change, the carrier mobility in the SiC crystal is improved, the resistance of the SiC crystal is reduced and, therefore, the on-resistance of the SiC semiconductor device is reduced.
