  • Patent number: 10368191
    Abstract: A confined space estimation system, and a confined space estimation method capable of accurately confirming a confined space formed in the event of a disaster, estimates a confined space comprising a storage device which stores information indicating a geographical space, and a processor which divides the geographical space into grids. Based on location information sent from a terminal, the processor periodically aggregates a number of terminals within the grids or a number of terminals that passed through boundaries between the grids, extracts grids or boundaries in which the aggregated number of terminals is a predetermined number and in which there is no change in the aggregated number of terminals, determines whether the extracted grids or boundaries can be linked to form an annular shape, and, if the annular shape can be formed, estimates a geographical space configured from the grids within the formed annular shape as the confined space.

  • Patent number: 8945246
    Abstract: An object of the present invention is to provide a method for producing a liquefied fuel oil using biomass as a feedstock, in which a relatively inexpensive liquefaction apparatus is used; a good balance is maintained between the liquefaction of water-insoluble lignin and the liquefaction of water-soluble cellulose to achieve a high yield of the liquefied fuel oil based on the biomass solids content; and the amount of ash derived from an alkali catalyst and the like is low. The method for producing a liquefied fuel oil using biomass as a feedstock is characterized by adding, to biomass comprising lignocellulose, a solvent comprising an organic solvent and having a moisture content adjusted to 10 to 25 wt %, including moisture contained in the biomass, and liquefying the biomass at a temperature of 250 to 350° C.
