  • Patent number: 7166661
    Abstract: An organic-inorganic composite material is formed by polycondensating a metal alkoxide through hydrolysis until the unreacted metal alkoxide is reduced to 3 vol. % or less, and mixing it with an organic polymer. The composite material has a light transmittance of at least 90% per 10 ?m material thickness for light of 600 to 1000 nm. The metal element content of the composite material is preferably 0.1 to 46 wt. %, more preferably 5 to 37 wt. %. By laminating layers of such organic-inorganic composite materials having respective different compositions, the resulting laminate has a concentration gradient wherein the metal element content increases or decreases monotonously, or increases and decreases in succession, from one side to the other side of the laminate. The resulting refractive index varies opposite the metal element content. The material can be used for an optical waveguide or a light transmission structure.

  • Patent number: 7158786
    Abstract: A radio bus system, a radio communication apparatus and a registration communication method which can ensure a minimum level of secrecy even when radio is used during an authentication information registration procedure. A hub station and each terminal comprises a mode switching control circuit (10) for switching between two modes, one being a registration mode to be used for the transmission and reception of registration data, and the other being a normal mode to be used for the transmission and reception of general data other than the registration data, a scrambler (transmitter means) (22) for transmitting data after providing the data with predetermined data processing corresponding to the mode switched to, and a descrambler (receiver means) (27) for performing on received data a predetermined restoration process corresponding to the mode switched to. Restoration of the received data is enabled only when the mode on the transmitting end and that on the receiving end correspond with each other.

  • Patent number: 7103354
    Abstract: A node configuration information management method and a wireless network system whereby node configuration information about a wireless bus comprising a hub station and a plurality of nodes is managed by the hub station in a centralized manner so that the hub station can share the latest node configuration information with all of the nodes. According to the node configuration information management method, when the node information in the wireless bus 11 is modified, a node notifies the hub station of the modification via a modification notifying packet.
