  • Publication number: 20060211505
    Abstract: The present invention presents a structure for preventing a shaft of constant velocity joint from coming off which allows changing design of connection between the shaft and an inner joint member to a type for disassembly or anti-disassembly. The anti-disassembly type is realized in such a manner that a wall at an opposite side to a shaft pulling out direction of a retaining ring groove of the shaft is used as a contacting part to a retaining ring, wherein at least two points are formed on the contacting part, one of which is on a perpendicular surface and the other is a corner of the contacting part, these two points are contacted with an inner surface of the retaining ring thereby provides the anti-disassembly type for preventing the ring from being contracted in a radial direction.

  • Patent number: 6548747
    Abstract: In an information service system whereby a server apparatus distributes music performance data to a telephony terminal apparatus through a network, the telephony terminal apparatus includes a storage section that stores an application program to be executed by a processing section for sending to the server apparatus a search query effective to specify target music performance data and acquiring the target music performance data from the server apparatus for exclusive use by the application program. In the server apparatus, a first distributing section responds to the search query in the form of contents that are dedicated for use by the application program. A second distributing section of the server apparatus responds to a request from the telephony terminal apparatus for distributing second contents of the same target music performance data to the telephony terminal apparatus such that the second contents can be treated by the telephony terminal apparatus independently of the application program.
