  • Optimal path search system and optimal path search method
    Patent number: 9057619
    Abstract: An optimal path search system, which optimizes a travel path of a moving object, comprising: a path information database; and a path search unit that searches for an optimal path that exhibits a minimum travel cost borne by the moving object, from among travel paths of the moving object, wherein: the path search unit is configured to: determine destination points on the path network; search for at least one nearest node to each of destination points, search for a second travel path along which the moving object travels by passing through the at least one nearest node and all of the at least one destination point, determine the second travel path for which a travel cost is minimum; and search for the travel paths followed by using each of a plurality of moving means, respectively, in a case where the moving object travels along the optimal path.

  • Method for producing fiber reinforced plastic rods having helical ribs
    Patent number: 5182064
    Abstract: A method for producing a fiber reinforced plastic rod having ribs on its surface by impregnating a reinforcing material which has continuous long fiber bundles with an uncured liquid resin. A rib forming member is separately prepared by impregnating a fiber bundle reinforcing material with an uncured liquid resin. A fiber reinforced plastic rod is formed by helically applying the rib forming member to the surface of the substrate forming member and together curing the two members into an integral body. A fiber reinforced plastic rod, prepared in accordance with this method, is also described.
