  • Publication number: 20200399847
    Abstract: In a pneumatic fender, reinforcing layers of a body portion and reinforcing layers of a predetermined range in the longitudinal direction of a fender near a boundary between each hemispherical portion and the body portion are formed by aligning cords of reinforcing layers of the body portion and that of the predetermined range in parallel, and in a neutral state without expansion, the cords of the reinforcing layers of the body portion meet each other and the cords of the reinforcing layers of the predetermined range meet each other, and cord angles A and B are each set to from 15° to 45° with respect to the longitudinal direction of the fender. When the interior of the fender is set to a specified internal pressure, the cord angles A and B increase to extent of a static angle, and the body portion and the predetermined range expand.

  • Patent number: 8233430
    Abstract: A terminal transmits a request for a resource assignment to a base station, and acquires a value of a resource for data transmission. The terminal does not transmit the new data to the base station when the resource for data transmission does not exist, and transmits the new data to the base station otherwise, after acquiring the value. The terminal autonomously transmits, when the new data is transmitted to the base station and a NAK signal is received from the base station, the retransmission data to the base station without sending a transmission request to the base station for resources to transmit the retransmission data.

  • Patent number: 7233615
    Abstract: In the timing correcting device, a RAKE path detecting circuit 1 detects a plurality of path candidates to be tracked, from a reception signal, and outputs a “timing of a path” and a “detection correlation value” corresponding to each path candidate, as a result of the detection. Next, each tracking-path candidate deciding circuit (2a, 2b, 2c, . . . ) generates a predetermined decision standard that is necessary for selecting an optimum path timing from timings of the path candidates, based on an individually allocated result of the detection. Further, the tracking-path selecting circuit 3 selects a timing of an optimum path to be tracked, based on the result of the detection and the predetermined decision standards. Then, a comparator circuit 5 compares a predetermined reception reference timing given from the outside with the optimum path timing, and calculates a phase difference between the two.

  • Publication number: 20070121569
    Abstract: A terminal transmits a request for a resource assignment to a base station, and acquires an initial value of a resource for data transmission that can be reduced with time. The terminal does not transmit the new data to the base station when the resource for data transmission is not remained, and transmits the new data to the base station otherwise, after acquiring the initial value. The terminal transmits, when the new data is transmitted to the base station and a NAK signal is received from the base station, the retransmission data to the base station regardless of a state of the resource for data transmission.

  • Patent number: 7024173
    Abstract: A control unit measures a phase error between a reference timing of a mobile station and a reception timing from a base station based on reception data from a reception unit and a count from a reference timing counter unit, determines a frequency deviation correction value calculation period corresponding to the measured phase error, and outputs it to a frequency deviation correction value calculation unit. The frequency deviation correction value calculation unit does not calculate a deviation at every reception time when intermittent reception is repeated, but calculates a deviation at intervals following the frequency deviation correction value calculation period given from the control unit.
