  • Patent number: 10859708
    Abstract: A test signal generator generates a first test signal. A test signal transmitter transmits the first test signal. An RF receiver unit receives the first test signal and a first satellite signal through a receiving antenna, and generates a second test signal and a second satellite signal, respectively. Each of first and second demodulators calculates a correlation value between the second satellite signal and the spreading code to acquire a satellite. A first failure detector unit compares a signal intensity of the second test signal with a threshold to generate a first failure detection signal. A second failure detector compares the satellites acquired by the first and second demodulator to generate a second failure detection signal. A state determiner determines whether and where a failure exists, using the first and second failure detection signals.

  • Patent number: 10201808
    Abstract: Disclosed is a method for preventing a photocatalyst from decreasing in hydrophilicity due to contamination by components seeping from a sealing material for anchoring a construction material, exterior material, glass structure, or other article on which a photocatalyst layer is formed. In said method, a transparent sealing-material-component seepage-prevention layer, which contains a modified epoxy resin comprising polymerizable unsaturated monomers graft-polymerized onto or copolymerized with an epoxy resin, is formed on the surface of the sealing material. Said polymerizable unsaturated monomers include a carboxyl-group-containing monomer, and a modified epoxy resin obtained by a carboxyl-group/epoxy-group reaction after graft polymerization or copolymerization is more favorable.

  • Patent number: 8774992
    Abstract: A next station state estimating unit estimates a preceding train position from information about a stop track circuit of a current train and from a signal aspect table. It estimates the time, at which the preceding train exits the next station and brake pattern before the station is canceled, from information about the preceding train position, from information about the occupied track circuit on which the current train is present and related information between track circuits and a station and information about occupied duration of the station, which are retained in a track database, and from a history of the preceding train position retained in a history retaining unit. The time estimated is sent to a driver's cab by a communication unit.
