  • Publication number: 20080223450
    Abstract: A flow control valve includes a seal member disposed within an annular space. The annular space is defined between at least one of bearing fitting portions of a flow path defining member and a corresponding valve shaft portion of a valve member opposing to each other in a radial direction with respect to an axis of the valve shaft portion and between an end face of a corresponding bearing and an end face of a valve body portion opposing to each other in a direction of the axis. The seal member can seal between the bearing fitting portion and the corresponding valve shaft portion with respect to the radial direction and can also seal between the corresponding bearing and the valve body portion with respect to the axial direction.

  • Patent number: 6636513
    Abstract: For example, a communication service controlling exchange apparatus (1) which can control a condition of a communication service to be provided includes call control memories (131-1 to 131-M) individually provided for paths between user terminals. User terminal registration information of those user terminals which can enjoy a communication service of a desired form is registered in the call control memories (131-1 to 131-M), and a communication service providing section (121) for linking the call control memories (131-1 to 131-M) with each other so that a communication service of the desired form can be provided is formed. A link changing control section (122) for changing the mutually linked condition of the pertinent ones of the call control memories (131-1 to 131-M) is provided in order to allow form changing to a communication service of a different form. Consequently. communication services of a plurality of kinds of forms can be provided by the single exchange apparatus (1).

  • Publication number: 20030179712
    Abstract: The quality and performance of the connectionless communications system are improved. When a BOM is received, the destination address DA of the L3-PDU stored in the payload of the BOM is retrieved, and the tag information is obtained from the DA (S11). The output message identifier MID is reserved (S12), and the tag information and output MID are assigned to the BOM (S13). Then, the tag information and output MID are written to the table. When a COM is received, the tag information and output MID are retrieved using the MID of the COM as a key, and the information is provided for the COM (S31 and S32). When an EOM is received, the tag information and output MID are retrieved using the MID of the EOM as a key, and the information is provided for the EOM (S41 and S42). Then, the output MID is released (S43).
