  • Publication number: 20200072461
    Abstract: This solid fuel burner is provided with: a venturi tube in which a channel for mixed fluid in a fuel nozzle narrows toward the center in the channel cross section; a fuel concentrator that imparts, to the mixed fluid, a velocity component away from the center of the fuel nozzle; and a channel separation member that separates the channel of the fuel nozzle into an internal side and an external side; wherein the channel separation member is shaped in such a way that the cross sectional area of an external channel is larger at the downstream end than at the upstream end, and the upstream end of the fuel concentrator is located between the upstream end and the downstream end of an expanded portion of the venturi tube. This solid fuel burner prevents solid fuel particles, which is ground biomass fuel, from adhering and depositing inside the nozzle.

  • Publication number: 20200047797
    Abstract: Provided are a lane separation line detection correcting device/method and an automatic driving system for stabilizing the behavior of a vehicle by correcting overestimated curvature information resulting from an erroneous detection of a curvature of a lane separation line. A travel speed detecting circuit detects, for example, a target travel speed as vehicle sensor information. A maximum curvature estimating circuit estimates, based on the target travel speed, a maximum curvature of a road along which an own vehicle is traveling. A curvature correcting circuit corrects a curvature of a lane separation line input thereto based on the maximum curvature. A control unit controls steering of the own vehicle based on the lane separation line having a corrected curvature. As a result, vehicle steering can be automatically controlled so as to prevent the own vehicle while traveling from departing from a driving lane.

  • Publication number: 20190391400
    Abstract: A video display system includes a display unit, a projection unit, and a display control unit. The display unit displays an image. The projection unit projects a virtual image onto a target space with outgoing light of the display unit. The display control unit shifts a projection position of the virtual image by changing at least one of a projection distance or an angle of depression. The projection distance is a distance from a viewpoint to the virtual image. The angle of depression is an angle from which the virtual image is viewed from the user's viewpoint. The display control unit changes the projection distance of the virtual image in accordance with a distance instruction and changes at least one of the projection distance or the angle of depression such that the virtual image is projected onto a displayable region of the target space.
