  • Publication number: 20200048728
    Abstract: The present invention enables quick cooling of steam-treated objects and thus reduces the manufacturing time of steam-treated products such as black coated steel sheets. The present invention provides a method for manufacturing steam-treated products, which involves a steam treatment step that introduces steam into a closed container (10) containing a treatment object (1) and brings the treatment object (1) into contact with the steam, and a treated object cooling step that cools the object (1) treated with steam in the steam treatment step, wherein said treated object cooling step introduces coolant gas into said closed container (10), brings said treated object (1) into contact with the coolant gas, and discharges the introduced coolant gas from said closed container (10).

  • Publication number: 20190031219
    Abstract: A moving path memory stores a moving path of a train in advance. A signal receiver receives satellite positioning signals. A position calculator calculates measured positions and receiver clock errors, based on the satellite positioning signals and the moving path. A error area calculator sets vector pairs, each consisting of arbitrary two vectors perpendicular to each other on a plane spanned by a tangent vector and a radial vector of a tangent circle of the moving path at the measured positions, and calculates an error area for each vector pair, based on the measured positions, the receiver clock errors, and positions of positioning satellites. A position range extractor extracts a part of the moving path included in each error area, as a candidate position range corresponding to the error area. A position range restrictor determines a common area of the candidate position ranges, as a position range of the train.

  • Publication number: 20180203127
    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.
