  • Patent number: 11952208
    Abstract: A wet particle storage tank includes a tank body capable of storing wet particles containing particles and solvent. The tank body has an upper storage section having a supply port through which the wet particles are supplied, a lower storage section located below the upper storage section and having a discharge port through which the wet particles are discharged, and a bridge forming section provided between the upper storage section and the lower storage section. The bridge forming section facilitates formation of a bridge by the wet particles to block falling of the wet particles from the upper storage section to the lower storage section.

  • Patent number: 9013579
    Abstract: A vehicle surrounding-area monitoring apparatus that, when recognizing an obstacle, allows for easy determination of the positional relationship between the obstacle and scenery included in a video image of the area surrounding the vehicle, generates a narrow view-field region that is a part of the video image as a notable video image, and if an obstacle region that is a region of the recognized obstacle in the video image is located outside of the narrow view-field region and if the obstacle region is contained in an image region that is partially overlapping with the narrow view-field region and is a part of the video image, generates the image region as a notable obstacle image so as to generate a surrounding-area monitoring display image comprised of the notable video image and the notable obstacle image.
