  • Patent number: 8331376
    Abstract: A mobile communication system includes a radio network control apparatus having inside a function block for processing a downlink shared channel and table means for storing various setting information related to the downlink shared channel communication and the downlink shared channel multi-cast communication. According to the information, a multi-cast communication (including uni-cast communication) is realized by using the downlink shared channel for one or more mobile apparatuses. Moreover, a base station has a function to transmit the downlink shared channel data and signaling data received from a radio network control apparatus, to a mobile apparatus via a radio line. Furthermore, it is possible to multi-cast data selectively to a particular mobile apparatus being call-connected.

  • Patent number: 8254935
    Abstract: A packet transferring/transmitting method is provided for use in a mobile communication system 50. In this packet transferring/transmitting method, an upper node 1 determines the implementation of handover (determination step), and a handover addressing node 2 transfers, of a plurality of packets, a non-transmitted residual packet to a handover addressed node 3, and the upper node 1 transmits a new packet to the handover addressed node 3 (transfer/transmission step). This enables maintaining the number of users to be accommodated while securing a wide bandwidth, sharing a line with high efficiency at soft handover, avoiding data residual in the case of the employment of variable communication rate, and preventing an increase in retransmission.

  • Patent number: 8151396
    Abstract: After a liquid sample between a sample-holding platform 11 and a window plate 22 is measured, a window plate holder 23 is raised, and a head 14 is moved from a standby position into the gap between the window plate 22 and the sample-holding platform 11. Then, the window plate holder 23 is lowered so as to press the window plate 22 onto the head 14 until the head 14 touches the sample-holding platform 11 below. Then the head 14 is swung back to the original position, whereby a wipe material 40 fitted on the head 14 simultaneously wipes off the liquid sample from both the lower surface of the window plate 22 and the upper surface of the sample-holding platform 11. Pressing the arch springs 35 enables the wipe material 40 to be easily attached to or detached from the head 14.

  • Patent number: 7811171
    Abstract: A game image representing a part or all of an identical game space is displayed on game machines. A first game machine detects the link strength of wireless communication between the first game machine and a second game machine. The first game machine executes predetermined game processing such that a processing result changes depending on the detected link strength. Further, the first game machine updates the game image based on a result of the predetermined game processing. The first game machine sends game processing information indicating the result of the predetermined game processing, to the second game machine. The second game machine updates the game image based on the game processing information sent from the first game machine.
