Abstract: A flowchart drawing apparatus (1) receives an input of a new process from an input apparatus (2). Further, in a case where a display position of the input process is overlapped with a display position of a connector of an existing flowchart stored in a part information table (300), a part information managing section (202) performs a process of inserting the input process between processes positioned on upper and lower sides of the connector. Next, a flow position calculating section (203) calculates a display position so that the respective processes are equivalently arranged, and a flow display section (204) displays a flowchart that is a process result on a display apparatus (3).

Abstract: A sliding-type tripod-shaped constant-velocity universal joint capable of being downsized while reducing induced thrust force. The constant-velocity universal joint includes: an outer race; a tripod including a boss portion and three tripod-shaft portions being inserted into roller grooves; and rollers. And, a shaft-axis-wise width of the tripod-shaft portions is formed smaller as it goes from the root side to the leading-end side in a torque transmission region of the tripod-shaft portions. Further, a torque-transmission-wise width of the tripod-shaft portions is formed greater as it goes from the root side to the leading-end side in the torque transmission region when defining a direction that intersects with the shaft axis and the tripod-shaft portions orthogonally as a torque transmission direction.

Abstract: Upon reception of a retrieval request containing a retrieval key word from a client, a business flow registration information table is searched based on the retrieval key word to acquire a flow ID and a node ID of a business flow containing the retrieval key word. The flow ID and the node ID acquired are stored in a retrieval result table. With reference to a business flow operation history table, the node use count of the acquired node ID is divided by the flow use count of the acquired flow ID to calculate a node pass ratio. The calculated node pass ratio is stored in a node pass ratio table. With the node pass ratio as a score, the node pass ratio information is sorted in the descending order of the score. The retrieval request display data is generated in the order of sorting, and sent to the client.

Abstract: A sliding-type tripod-shaped constant-velocity universal joint that can reduce induced thrust force by preventing the tangent-point back-surface side of rollers from contacting with roller grooves in the case where the rollers and the roller grooves make an angular contact at two locations. An outer peripheral surface of the rollers makes an angular contact with respect to the roller grooves at two locations, and an inner peripheral surface of the rollers is formed as a convex-shaped curve that is directed to the inner side in an axially cross section of the rollers. And, the rollers are made swingable with respect to tripod-shaft portions.

Abstract: Clients are prevented from issuing allocation requests to the same items by using a condition depending upon work and a selection key when selecting items to be allocated. By thus selecting allocation subjects so as not to cause competition and thereby reducing exclusive waiting, the efficiency of allocation processing in a large scale workflow system can be raised.

Abstract: The contact angle of the ball 15 with each first guide track 21 of an inner joint member 12 is made to become smaller gradually from an opening portion side toward a bottom portion side, and the curvature radius for the first guide track 21 is made to become larger gradually from the opening portion side toward the bottom portion side. If the contact angle only were made to become smaller gradually from the opening portion side toward the bottom portion side, the contact angle would become too small thereby to cause chattering in rotation to be generated. If the curvature radius only were made to become larger gradually from the opening portion side toward the bottom portion side, a contact ellipse M2 defined by the ball 15 and the first guide track 21 would become tool small, which would cause the ball 15 to make dents on the surface of the first guide track 21.

A coefficient of sliding friction between the ball and a rolling face on the inner groove with which the ball is in contact, and a coefficient of sliding friction between the ball and a rolling face on the outer groove with which the ball is in contact are larger than a coefficient of sliding friction between the ball and a sliding face on the window portion with which the ball is in contact.

Abstract: A power transmission shaft which can be evaluated on torsional fatigue strength based on a management indicator different from compressive residual stress in an outer surface. In a power transmission shaft having outer circumferential serrations 1a, 1b, torsional fatigue strength is evaluated by using compressive residual stress at a depth of 30 ?m (and 50 ?m) from an outer surface of a rising portion of each concave of the outer circumferential serrations 1a, 1b as a management indicator. A high torsional fatigue strength can be secured by having a compressive residual stress of 1150 MPa or more at a depth of 30 ?m (and 50 ?m) from the outer surface.
