  • Publication number: 20160126741
    Abstract: A storage battery equipment includes a converter, a system interconnection inverter, and a controller. The converter extracts direct current power from a storage battery, then converts a voltage of the direct current power and outputs the direct current power. The system interconnection inverter converts the direct current power outputted from the converter into an alternating current power. The controller controls the system interconnection inverter such that an amount of power output from the system interconnection inverter to a load matches a preset target discharge amount.

  • Publication number: 20160073742
    Abstract: The inventive fastener member, fastener structure, and support member can reduce rattling and noise without reducing the ease of assembly. The fastener member 10 includes guided portions 12A, 12B that are guided in the mounting direction D1 by guide portions 22A, 22B. Elastically deforming portions 30A, 30B formed on the guided portions 12A, 12B can elastically deform in a direction that intersects with the mounting direction D1. When the fastener member 10 is mounted, the elastically deforming portions 30A, 30B deform elastically, so it can be easily assembled without interference between the guide portions 22A, 22B and the guided portions 12A, 12B. After it is mounted, the fastener member 10 is supported without play by the guide portions 22A, 22B of the support member 20 due to the elastic force generated between the elastically deforming portions 30A, 30B and the receiving portions 40A, 40B.

  • Publication number: 20160071935
    Abstract: A native p-type metal oxide semiconductor (PMOS) device that exhibits a low threshold voltage and a high drive current over a varying range of short channel lengths and a method for fabricating the same is discussed in the present disclosure. The source and drain regions of the native PMOS device, each include a strained region, a heavily doped raised region, and a lightly doped region. The gate region includes a stacked layer of a gate oxide having a high-k dielectric material, a metal, and a contact metal. The high drive current of the native PMOS device is primarily influenced by the increased carrier mobility due to the strained regions, the lower drain resistance due to the raised regions, and the higher gate capacitance due to the high-k gate oxide of the native PMOS device.

  • Publication number: 20150381396
    Abstract: A base station classifies at least some of radio communication apparatuses belonging to the same cell into a plurality of groups. The base station assigns to a first group a first signal sequence that is orthogonal to a cyclically shifted version thereof, and assigns to a second group a second signal sequence that is orthogonal to a cyclically shifted version thereof and that is different from the first signal sequence and from the cyclically shifted version of the first signal sequence. The radio communication apparatus belonging to the first group performs spread modulation on data using the first signal sequence or a signal sequence obtained by cyclically shifting the first signal sequence. The radio communication apparatus belonging to the second group performs spread modulation on data using the second signal sequence or a signal sequence obtained by cyclically shifting the second signal sequence.
