    Abstract: A wheel bearing assembly has a disk rotor for a brake integrally formed with a wheel-mounting flange of an inner member. Raceways opposite double-row raceways of the outer member are arranged on separate ring members pressed onto a tubular portion of the inner member. Thus, it is unnecessary to mount a brake rotor to the wheel bearing assembly, to reduce the number of parts, and to use different materials for the inner member and the inner ring members. For example, an FC-family cast iron, which is superior in seizure resistance, can be used for the inner member, and a tough bearing steel can be used for the ring member to achieve both excellent brake function and bearing function.

    Abstract: A data communication system includes a server, data link started side apparatus, data link starting side apparatus, and originating server. The server provides a service through a network. The data link started side apparatus performs line control between itself and the line connection destination, and performs LAN control between itself and the server through the network, thereby relaying packets between the line connection destination and the server. The data link starting side apparatus is connected to the data link started side apparatus, disconnects the line between itself and the data link started side apparatus on the basis of an MITF dial-up dormant protocol when there is no communication between itself and the server for a predetermined period of time, and shifts to a dormant state. The originating server originates data reception notification by using the originating telephone number transmitted from the data link started side apparatus when a packet communication state between the data link starting side apparatus and the data link started side apparatus is in the dormant state, and the data link started side apparatus receives data addressed to the data link starting side apparatus from the server. A data communication method and a server are also disclosed.
