Abstract: A method and apparatus for selecting a client computer as a relay server to rebroadcast common application information that is broadcast from a server system over a network. The client computer is selected randomly to rebroadcast the User Datagram Protocol (UDP) information received from the server system and client computers receiving the UDP information from another client computer relay server on the network do not rebroadcast the information. If the client computer selected to rebroadcast the common information fails to rebroadcast, another client computer is randomly selected as a relay server and takes over rebroadcasting the common information.

Abstract: A method for manufacturing a shaft member having a sintered part bonded thereto is simple and provides an increased process yield and a high accuracy in position and angle of the sintered part. A green compact is prepared by subjecting a metal or alloy powder to a compression molding.

Then, a sintering is carried out.

Abstract: The present invention provides a rotating electrical machine including a rotor core that does not produce narrow areas in rotor slots even if circumferential ends of fan-shaped segment cores are displaced radially outwardly and circumferentially during operation. In the present invention, slots near circumferential ends of the fan-shaped segment cores are made larger than slots in circumferential intermediate portions of the segment cores. With such a configuration, even if the circumferential ends of the segment cores are displaced radially outwardly and circumferentially during operation, the circumferential ends of the segment cores forming the large slots do not protrude into the slots formed in the circumferential intermediate portions of axially adjacent segment cores, thereby preventing narrow areas from being produced in the rotor slots.

Consequently, first display cells are defined between the second electrodes and the first electrodes on one side of the second electrodes, and second display cells are defined between the second electrodes and the first electrodes on the other side of the second electrodes.
