  • Patent number: 10581346
    Abstract: A motor capable of holding a vibrator without increasing a dimension thereof in a traveling direction (driving direction) and without having looseness. The motor includes a vibrator and a holding unit that holds the vibrator, and moves the vibrator and a sliding member in frictional contact with the vibrator relative to each other by vibrating the vibrator. A pressurizing unit pressurizes the vibrator against the friction member, and holding springs generate a holding force for causing the holding unit to hold the vibrator. The holding unit is not disposed between the pressurizing unit and the vibrator. A holding direction of the holding force generated by the holding springs and a pressurizing direction of a pressurizing force generated by the pressurizing unit are substantially parallel to each other.

  • Patent number: 8979656
    Abstract: A game system includes multiple game machines which implement a game by alternating turns. Each game machine implements the game on its turn, and transmits game progress information to the other game machines. The game is implemented in accordance with the transmitted game progress information. A host game machine of the game machines transmits turn determination information to the other game machines, and receives turn completion information from each of the other game machines. When the turn confirmation information is not returned from one of the other game machines, the host game machine recognizes that communication has been cut off. When the communication has been cut off, the host game machine functions as a substitute for the cut off game machine.

  • Patent number: 8228537
    Abstract: A print managing server is connected to a plurality of printers through a network and stores print data which can be printed by the printer in combination with user information. The print managing server has control means for controlling execution of a command including the user information which is received from the printer. The control means controls in such a manner that when the command is received, if a printing process corresponding to the user information included in the command is being executed for the other printer, the printing process which is being executed is stopped for the other printer and a process corresponding to the command is executed.

  • Patent number: 7627292
    Abstract: An eigen value expansion section 103 calculates eigen values and eigen vectors in a correlation matrix or covariance matrix of input signals. When the ratio between a maximum eigen value and other eigen values is equal to or lower than a threshold, an assignment method selection section 104 selects a code assignment method whereby systematic bits are transmitted with their respective eigen vectors. As a result, a communication apparatus 100 transmits a systematic bit X with the respective eigen vectors. On the other hand, when the ratio between a maximum eigen value and other eigen values is greater than the threshold, the assignment method selection section 104 selects a code assignment method whereby systematic bits are transmitted with only the eigen vector having the maximum eigen value. As a result, the communication apparatus 100 transmits the systematic bit X with only the eigen vector having the maximum eigen value.

  • Patent number: 7561894
    Abstract: In order to appropriately control transmit power of a common channel for an MBMS (Multimedia Broadcast/Multicast Service) so as not to become excessive, a mobile station 1 transmits a TPC command for an S-CCPCH to a base station through an uplink DPCH1 and a mobile station 2 transmits a TPC command for an S-CCPCH to the base station through an uplink DPCH2. When either one of the TPC command for the S-CCPCH transmitted from the mobile station 1 and the TPC command for the S-CCPCH transmitted from the mobile station 2 is a TPC command instructing “Up”, the base station increases transmit power of the downlink S-CCPCH and decreases transmit power of the downlink S-CCPCH when both TPC commands instruct “Down”.

  • Patent number: RE43614
    Abstract: An assignment section 101 determines communication resource assignment to communication terminals based on a transmission rate at which communication is possible for each subcarrier of each communication terminal, and instructs a buffer section 102 to output forward transmission data. In addition, the assignment section 101 instructs a frame creation section 103 to perform forward transmission data symbolization, and also outputs a signal indicating communication resource assignment to each communication terminal. The buffer section 102 holds forward transmission data, and outputs forward transmission data to the frame creation section 103 in accordance with instructions from the assignment section 101. The frame creation section 103 symbolizes a resource assignment signal and transmission data to create a frame, which it outputs to a spreading section 104.
