  • Patent number: 8923866
    Abstract: In femtocell operation, when a wireless communication terminal whose ID is not registered (ID unregistered terminal) has entered a femtocell's area, the disclosed invention prevents interference between the femtocell and the ID unregistered terminal and interference between the ID unregistered terminal and an ID registered radio communication terminal and prevents a decrease in the throughput of the femtocell and these terminals. In a radio coverage area formed by a radio base station, if a drop of received power from a radio communication terminal occurs and the frequency of reporting the ID of the base station now communicating with the terminal has become less than a given value, it is decided that the terminal is located indoors. For the terminal, if its handover to a femtocell was found to be rejected by MME, the terminal is temporarily permitted to be handed over to a femtocell.

  • Patent number: 8580940
    Abstract: Protoporphyrinogen oxidase having an activity of imparting acifluorfen resistance and gene thereof are provided. Cyanobacterium protoporphyrinogen oxidase gene is identified by introducing a protoporphyrinogen oxidase gene of Arabidopsis into cyanobacterium, disrupting a cyanobacterium gene with a transposon, selecting a mutant strain in which protoporphyrinogen oxidase gene is disrupted, identifying the disrupted protoporphyrinogen oxidase gene, and isolating the disrupted protoporphyrinogen oxidase gene. This procedure is effective as a gene isolation technique when a protein derived from other organism species that is homologous to a known protein (e.g., protoporphyrinogen oxidase from cyanobacterium) can not be found in a gene database of the other species.

  • Patent number: 7928802
    Abstract: An RF amplification device has amplification elements which amplify a radio frequency input signal in wireless radio communication. Transmission line transformers are coupled to one of an input electrode and an output electrode of the amplification elements and have a main line Lout arranged between the input and the output, and a sub line Lin1 arranged between an AC ground point and one of the input and the output and coupled to the main line Lout. By applying an operating voltage different from the ground voltage level to the AC ground point, the operating voltage is supplied to the output electrodes of the amplification elements via the sub line from the AC ground point. In realizing a high-performance load circuit in an RF amplification device, it is possible to avoid increase of a module height of an RF module.

  • Patent number: 7825731
    Abstract: An RF amplifying device includes a transmission line transformer coupled to an output electrode of a power transistor for generating transmission power to be fed to an antenna. The transmission power from the output electrode of the power transistor is fed to one end of a main line of the transmission line transformer, and one end of a secondary line of the transmission line transformer is coupled to an AC grounding node. The other end of the secondary line is coupled to the one end of the main line, thereby generating the transmission power. Coupling energy is transmitted from the secondary line to the main line. Coupling members electrically coupled to the output electrode of the power transistor are electrically coupled to a joint formed in either the main line, or the secondary line, at part of the energy coupling part.
