  • Patent number: 10851493
    Abstract: A wire rope formed from a resin core and six strands, the resin core having an inner core with a circular cross section and an outer layer built up on the periphery thereof. The outer layer has a melting temperature lower than that of the inner core. The six strands are twisted together helically on the periphery of the resin core in an intertwining die in such a state that gaps are assured between the strands. The resulting wire rope is heated in a heating unit at a temperature higher than the melting temperature of the outer layer but lower than the melting temperature of the inner core. The wire rope is formed by subsequently compressing the six strands from the periphery thereof in a compressing die. The molten outer layer is hardened by natural cooling, after which the wire rope is taken up.

  • Publication number: 20200278980
    Abstract: A database processing apparatus or the like is proposed, which is suitable for performing aggregation/search processing or the like for a database in the form of raw data such as CSV source data without involving preliminary extraction or the like. A database processing apparatus manages a group map file storing values converted from data values set as a name identification target when the database is subjected to aggregation, and an address map file for accessing each data item of a CSV file stored in a second storage unit. An aggregation result breakdown extraction unit uses the group map file to identify data of the CSV file that corresponds to the aggregation result, and uses the address map file to access the data of the CSV file so as to display the breakdown of the aggregation result on a display unit.

    Abstract: An optical transmission device includes a first wavelength multiplexer, a second wavelength multiplexer, a wavelength converter and a third wavelength multiplexer. The first wavelength multiplexer multiplexes optical signals in a first wavelength band to generate first wavelength multiplexed light. The second wavelength multiplexer multiplexes optical signals in the first wavelength band to generate second wavelength multiplexed light in a first polarization. The wavelength converter converts a wavelength of the second wavelength multiplexed light from the first wavelength band into a second wavelength band by a cross phase modulation among the second wavelength multiplexed light, first pump light in a second polarization and second pump light in the second polarization. The second polarization is orthogonal to the first polarization.
