  • Publication number: 20020017327
    Abstract: In a single seat valve apparatus, a valve box has upstream and downstream fluid flow channels. A cage is fixed in the valve box and has a flow rate control window for controlling an amount of the fluid flowing from the upstream to the downstream flow channel. A valve seat is provided to the cage. A valve body is slidably fitted in the cage, closes the control window, when seated on the valve seat, to block a passage of the fluid from the upstream to the downstream flow channel, and forms a passage of the fluid, when separated from the valve seat, from the upstream to the downstream flow channel through the control window. An opening is formed in the valve body in an axial direction of the cage and allows a fluid space and a space on one side in the axial direction of the cage to communicate with each other, to equilibrate a pressure applied by the fluid. A valve stem is connected to the valve body and moves it in the axial direction of the cage.

  • Patent number: 6258564
    Abstract: The invention is related to antibodies which specifically react with connective tissue type-human mast cells, a production method of the antibodies, hybridomas which produce the antibodies, a production method of the hybridomas and antigen proteins recognized by the antibodies. After cord blood cells were cultured in the presence of SCF and IL-6, they were further cocultured with primary culture of human skin fibroblasts, and connective tissue type-human mast cells were thus obtained. A rat was immunized using the cells, hybridomas were prepared and selected by an ordinary method, and novel monoclonal antibodies were harvested from the culture supernatant of the selected hybridomas. The monoclonal antibodies specifically reacted with connective tissue type-human mast cells.

  • Patent number: 5607541
    Abstract: An improvement is proposed in an electrostatic chuck, which is used in holding and transporting, for example, a semiconductor silicon wafer under processing in the manufacture of electronic devices, having an internal electrode layer sandwiched between two dielectric layers of a ceramic material. The disadvantage caused by the inherent porosity of the ceramic material can be dissolved by the invention according to which the pores are filled with a thermally decomposable liquid compound of silicon, aluminum and the like and then the ceramic material is heated in an oxidizing atmosphere so as to decompose and oxidise the impregnant compound into the oxide formed in situ and filling the pores so that the electrostatic attractive force can be increased as a consequence of the increase in the effective dielectric constant along with high resistance against any corrosive gaseous atmosphere as compared with conventional pore-filling materials such as epoxy resins.
