  • 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.

  • Patent number: 6857765
    Abstract: A decorative lighting equipment includes a shade that is transparent or translucent and formed into a tube with opposite ends, a light source for emitting a directional light flux, the light source being placed at one end of the opposite ends of the shade so that the directional light flux is transmitted within the shade toward another end of the shade, and the shade forming thereon hairlines which extend in a direction crossing the direction along which the directional light flux emitted from the light source is transmitted.

  • Patent number: 4890151
    Abstract: A method for forming an interconnection pattern of Al on a structure, such as a semiconductor device, includes the step of introducing ions of a selected material, such as As, P, B and Ar, into a film of Al to be formed into an interconnection pattern prior to the step of heat treatment, thereby substantially preventing undesired results, such as hillocks, when the pattern is heat-treated.

  • Patent number: 4814840
    Abstract: A process for manufacturing a reprogrammable semiconductor memory device, such as EPROM, and its resulting structure is provided. A substrate has a main surface which is provided with grooves formed by etching. An oxide film is formed on the main surface and the side and bottom surfaces of each of the grooves. And, a first layer of doped polysilicon is formed on the oxide film, and the first layer of doped polysilicon is disconnected at the bottom of each of the grooves by selective removal thereof. A second layer of doped polysilicon is formed on the first layer of doped polysilicon with an inter-layer electrical insulator sandwiched therebetween. Thus, the first and second layers of polysilicon, together with the inter-layer insulator, define a stacked-gate electrode structure. A pair of source and drain regions is formed in the substrate one on each side of the stacked-gate electrode structure.
