  • Patent number: 7529793
    Abstract: Reduces time for processing a request Simple Object Access Protocol, SOAP, message in a request means such as mobile equipment or the like. Sequence definition means divides one parent SOAP message as one request concerning a Web Service into segments of a Simple Object Access Protocol header and a SOAP body. Segment creation means creates the segment of the Simple Object Access Protocol body of the parent SOAP message and the segment of the SOAP header of the parent Simple Object Access Protocol message in this order. Sending means executes sending processing in parallel with creation processing by the segment creation means. Specifically, the sending means assigns one child Simple Object Access Protocol message enveloping the content of a segment to each of the segments, and sends each of the child Simple Object Access Protocol messages to the provider in accordance with a creation sequence of the segments.

  • Patent number: 7486292
    Abstract: The present invention provides methods, apparatus and systems to improve the quality of the arrangement of nodes in a graphics display, for which a graphics image consisting of nodes and arcs is generated, and to increase the processing speed. Nodes are sequentially added and arranged in a display space, and each time a new node is added, a predetermined dynamic model is employed to correct the locations of the new node and of nodes that were previously arranged in the display space. The nodes are arranged beginning with a node having numerous adjacent arcs, so that the nodes that are arranged early in the process are located nearer the center of the display space. In the graphics image thus formed in the display space, arcs located within a predetermined distance of a specific node are curved so they detour around the node.

  • Publication number: 20050039054
    Abstract: An authentication system with a single sign on having less influence on the service performance to provide a service via a network. The authentication system comprises a provider 20 for providing a service, a security token service 40, and a proxy service 30 interposed between the security token service 40 and the provider 20. The proxy service 30 preserves an authentication result of the security token service 40, and vicariously executes the authentication for a client based on the authentication result preserved by itself without transferring an authentication request received from the provider 20 to the security token service 40 under certain conditions. Moreover, when it is clear that a service can be provided to the client based on the service use history of the client 10 preserved by itself, the provider 20 provides the service to the client 10 without making the authentication request.

  • Patent number: 6524004
    Abstract: A compact externally pressurized gas bearing spindle assembly can increase the degree of vacuum in a vacuum chamber. In a spindle assembly wherein a rotary shaft is provided in a housing through a bearing gap, and compressed gas is introduced into the bearing gap to support the rotary shaft in a non-contact manner relative to the housing, an exhaust gas suction device for sucking gas discharged from the bearing gap is provided inside the housing or the rotary shaft. The bearing gap near the outside of the housing is smaller than the other bearing gap. Near the bearing gap near the outside of the housing, a non-contact seal gap is formed to prevent leakage of compressed gas into the vacuum chamber in a non-contact manner.

  • Publication number: 20030011601
    Abstract: A graphics image for hierarchical graph data is generated in order beginning with the topmost level. When a sub-graph for a specific level is generated, and then a sub-graph for a lower level for a specific node in this sub-graph is generated, the size of the node for which the lower sub-graph is generated is changed so that the lower sub-graph is included in this node. Further, nodes near the node for which the size has been changed are moved, so that these nodes do not interfere with the sub-graph for the lower level.
