  • Patent number: 9447441
    Abstract: A polyhydroxyalkanoate copolymer of 3HB (3-hydroxybutyrate), 3HP (3-hydroxypropionate) and 5HV (5 -hydroxyvalerate) disclosed. The polyhydroxyalkanoate can be used for bioplastic or biomaterial. A method for producing the polyhydroxyalkanoate comprises culturing a microorganism belonging to Ralstonia genus in a culture medium that comprises lactone and/or hydroxy acid or salt of hydroxy acid as a carbon source.

  • Patent number: 9270024
    Abstract: A PDMA terminal (1000) establishes communication by forming a plurality of spatial paths to another single radio apparatus. A plurality of antennas constituting an array antenna are divided into a plurality of subarrays corresponding to the plurality of spatial paths respectively. An adaptive array processing unit (USP) can perform an adaptive array processing for each of the plurality of subarrays. A memory (MMU) stores in advance information on the number of antennas associated with the number of spatial paths that can be formed by the array antenna. A control unit (CNP) controls a processing to transmit possible multiplicity information to another radio apparatus at a prescribed timing.

  • Patent number: 9204463
    Abstract: An RF unit and a modem unit receive a packet signal, containing information regarding a frame construction, which is transmitted from a base station apparatus in a first period of a frame at least including first periods and second periods. An extraction unit identifies the second period in the frame, based on the received packet signal. A setting unit sets a waiting time period in the identified second period. A carrier sensing unit carries out carrier sensing over the waiting time period set by the setting unit. The modem unit and the RF unit broadcast the packet signal based on a result of the carrier sensing.

  • Patent number: 8976687
    Abstract: It is specified that a frame containing at least the plurality of slots is repeated. A detecting unit detects a slot usable in the communications between terminal apparatuses, from among a plurality of slots. A modem unit and an RF unit broadcast the information on the detected slot. A power measuring unit in the detecting unit measures the respective received powers of the plurality of slots, and an empty slot identifying unit identifies a slot whose received power is less than a threshold value.

  • Patent number: 8503590
    Abstract: Preceding filters receive the inputs of a plurality of received signals associated respectively with a plurality of antennas. Subsequent filters band-limit the plurality of inputted received signals, respectively. A first combining unit derives a weight vector for the plurality of band-limited received signals and performs array synthesis on the plurality of band-limited received signals, using the derived weight vector. The second combining unit performs array synthesis on the plurality of inputted received signal signals, using the derived weight vector. A demodulator demodulates the array-synthesis result.
