  • Patent number: 8121554
    Abstract: A data rate is to be determined depending on circumstances. A control unit (30) transmits, at a predetermined frequency, a request signal by which to supply information on a data rate to a targeted radio apparatus compatible with a variable data rate. The control unit (30) receives rate information from the targeted radio apparatus. The control unit (30) sets a data rate used in the case of transmitting data, based on the information on a data rate contained in the rate information. The control unit (30) identifies the reliability level of the data rate contained in the rate information. And when the reliability level is low, the control unit (30) lowers the frequency at which the rate request signal is transmitted.

  • Patent number: 8075124
    Abstract: An ink containing a hydrophobic colloid charged with a positive zeta potential when the pH of the ink is within a range of over 4 and under 6. Silicon or silicon compound can be limited from being eluted into the ink from a circuit board formed from a silicon wafer or the like. Additionally, silicon or silicon compound, if eluted into the ink can be prevented from being deposited on a resistance heater and causing “cogation”, or to prevent the silicon or silicon compound from being deposited in an ink channel and nozzle to clog the nozzle.

  • Patent number: 8064388
    Abstract: A control unit aggregates packets which are to be sent to one or more terminal apparatuses, and produces aggregated packets. The control unit divides a certain period into a plurality of partial periods, allots each of the plurality of partial periods to any of the plurality of terminal apparatuses and produces a control signal with which to convey an assignment condition to the terminal apparatus. In the case of an aggregated packet where the packets for the plurality of terminals are aggregated, a baseband processing unit and the like transmit the aggregated packet together with the control signal to the plurality of terminal apparatuses. In the case of an aggregated packet where the packets for a single terminal are aggregated, they transmit the aggregated packet to the plurality of terminal apparatuses, without sending the control signal.

  • Publication number: 20110275251
    Abstract: To provide a terminals connecting structure which can prevent a terminal of two types of terminals which is mounted later from plunging into an inside of or pushing up a terminal which is mounted first with a simple structure in stacking the two types of terminals one on the other for connection in an electric equipment connecting terminal block. A plunge prevention portion 22 which is bent inwards towards an inverter terminal block 10 is formed at a leading end portion of a capacitor bus-bar terminal 20, and a guide rib 17 is formed on a lateral side of the terminal block 10 which faces an inverter connector terminal 30 in a position lying in proximity to a nut 12A so as to project outwards along a direction in which the inverter connector terminal 30 enters.

  • Patent number: 8054739
    Abstract: A storage unit stores a preamble signal defined in a legacy system and a preamble signal defined in a MIMO system. A monitoring unit in a transmitting apparatus monitors the existence of any communication apparatus which is not compatible with the MIMO system but accepts the legacy system. A channel characteristics acquiring unit derives the characteristics of a radio channel between the transmitting apparatus and a receiving apparatus. A selector selects a packet format based on a monitoring result obtained by the monitoring unit. The selector also selects where to place LTS, based on the characteristics of wireless channel derived by the channel characteristics acquiring unit.
