    Abstract: A computer generates semantic structure information from a document. The semantic structure information includes a plurality of semantic structures in a plurality of sentences in the document and a plurality of morphemes included in each of the plurality of sentences belong to a corresponding semantic structure. The computer generates a plurality of codes by encoding the plurality of morphemes for each of the plurality of sentences.

  • Publication number: 20190045329
    Abstract: An apparatus determines a plurality of candidate position groups each indicating an trajectory of estimated terminal positions on a candidate floor selected from among multiple floors, wherein the trajectory of estimated terminal positions on the candidate floor is estimated based on positions of base stations installed on the candidate floor and intensities of radio waves that have been transmitted by a terminal at time points and detected by the base stations. The apparatus identifies, from among the candidate floors selected from the multiple floors, a target floor on which the terminal actually exists, based on the trajectories of estimated terminal positions for the determined plurality of candidate position groups and a movement requirement that defines a condition of actual movement of the terminal on each of the candidate floors.

  • Patent number: 9669499
    Abstract: A double-wall pipe includes an outer pipe, and an inner pipe disposed inside the outer pipe. An outer wall of the inner pipe has thereon a ridge portion, which defines a groove portion extending in a longitudinal direction of the inner pipe. The outer pipe and the inner pipe are bent to have a straight portion extending straightly, and a bend portion bent from the straight portion. In the straight portion, the outer pipe has an inside diameter that is larger than an outside diameter of an imaginary cylinder defined by an outer surface of the ridge portion of the inner pipe. Furthermore, the ridge portion of the inner pipe contacts an inside surface of the outer pipe to be radially squeezed and held by the outer pipe, in the bend portion. The double-wall pipe can be suitably used for a refrigerant cycle device.

  • Patent number: 7995001
    Abstract: A dielectric resonator antenna which emits an electric wave by having a dielectric body resonate is disclosed. A magnetic material is contained in the electric body, thereby increasing the relative permeability to more than 1 and lowering the relative permittivity. Consequently, the Q-value of the resonance can be lowered while maintaining the rate of wavelength shortening. With this technique, a broadband dielectric resonator antenna can be realized.
