  • Patent number: 10435021
    Abstract: A vehicle control device includes a lane determining unit which, in the event there is a branching path or a merging path in a planned travel route of a host vehicle, is adapted to determine whether or not a lane in which the host vehicle is traveling differs from a lane in which the branching path or the merging path exists, and a lane change instructing unit which, in the event it is determined by the lane determining unit that the lane in which the host vehicle is traveling differs from the lane in which the branching path or the merging path exists, is adapted to set a route so that the host vehicle automatically performs a lane change into the lane in which the branching path or the merging path exists.

  • Patent number: 9102840
    Abstract: A polyurethane resin-bonded pigment may exhibit excellent image density, dispersibility, storage stability, and resolubility, and may form an ink film that exhibits marker resistance and rubfastness. The polyurethane resin-bonded pigment is produced by bringing (I) a pigment having a surface acidic group into contact with (II) a basic compound having two or more amino groups selected from a primary amino group and a secondary amino group in its molecule in an aqueous medium to obtain a pigment having an unreacted surface amino group, and bringing the pigment having an unreacted surface amino group into contact with (III) a water-dispersible polyurethane resin having an isocyanate end group and (IV) a polyisocyanate compound to bond the pigment having an unreacted surface amino group and the water-dispersible polyurethane resin (III) having an isocyanate end group via a urea bond.
