  • Publication number: 20070133457
    Abstract: A radio communication device includes a communication data selection unit for selecting from the received radio communication data containing communication time reservation request information in which a time slot for performing data transmission source radio communication device is described and a communication information analysis unit for extracting an identifier of the source radio communication device and the data transmission reservation time slot from the communication time reservation request information in the radio communication data. When the received radio communication data is addressed to the local device, a communication/response information generation unit correlates the identifier to the reservation time slot, records them in a communication reservation table, and generates communication time reservation response information including information of the reservation time slot.

  • Publication number: 20070026880
    Abstract: A beacon slot position control section (205) of a radio communication apparatus constituting a radio network system which detects whether empty beacon slots are present in a beacon period. When an empty beacon slot is present before the period in which the radio communication apparatus transmits a beacon, a movable counter (206) starts counting a specified number of super frames. When the count is completed, the radio communication apparatus transmits a beacon of the radio communication apparatus at the earlier empty beacon slot. Consequently, since the empty beacon slots are eliminated and the beacon period is compacted, even if the number of radio communication apparatuses joining the radio network system fluctuates dynamically, the radio communication apparatus can perform radio communication with high efficiency and less waste of consumed electricity.

  • Publication number: 20050002373
    Abstract: A network communication system is provided whereby communication stations can obtain priority for data transmission to communicate directly with each other in a contention-free mode communication period independently of a polling operation of the control station. The control station emits a series of beacons at equal intervals to initiate contention-free mode communication at the completion of a predetermined number of beacons. During the maximum contention-free mode communication period a contention-free communication operation is initiated, for allowing contention-free mode transmission, by a polling operation by the control station. A series of time-slots is imaginarily provided at equal intervals from the start of the contention-free period throughout the maximum contention-free period. A communication station conducts a call-connection procedure in order to obtain a priority for data transmission in a given set of time-slots.

  • Patent number: 6663714
    Abstract: The present invention is to provide a CVD apparatus having a high productivity, involving less contamination on the back surface of a substrate and having a high yield. A CVD apparatus for forming a thin film is characterized in that the interior of the vessel is divided into a upper portion and a lower portion (transfer chamber) by a support member for holding the ring chuck and the upper portion is further divide by inner wall into a deposition chamber and an exhaust chamber in axial symmetry around the same central axis. The deposition chamber communicated to the exhaust chamber through a gap between the inner wall and the ring chuck and/or holes provided in the inner wall. The transfer chamber is communicated to the deposition chamber or exhaust chamber through a gap formed between the ring chuck and the support member.

  • Patent number: 6471314
    Abstract: A method of cost-effective printing control for printing a variety of documents or images in color. An operator is notified whether printing is enabled as well as of the residual amounts of two or more printing agents. Printing data, including both character printing and graphics commands, is created for a given object to be printed. The amounts of each printing agent required for a given object is predicted and the object is printing if the quantities of all printing agents exceed their respective predicted amounts. No printing occurs and the printing operator is alerted if the amount of any one printing agent is below the amount predicted for that agent.
