  • Publication number: 20240175680
    Abstract: A road inspection system includes: an inspection determination part that determines, regarding road segments, each of which is a unit obtained by dividing an inspection target road, a need for inspection for the individual road segment; a control part that controls, based on the need for inspection for the individual road segment, measurement of a road surface state(s) of the road performed by a measurement vehicle that is capable of measuring the road surface state(s) or transmission of measured data obtained by the measurement; and a road surface inspection part that analyzes measured data received from the measurement vehicle and performs inspection.

  • Patent number: 5316821
    Abstract: A partition plate for multiple-stage adsorption separator includes a planar body member having opposing external surfaces and a peripheral edge with conduits providing fluid communication between the opposing surfaces and different points on the peripheral edge. Each of the opposing surfaces is provided with a peripheral rim and covered with a perforated plate whereby an open chamber is defined between the body member and a perforated plate at each of the external faces.

  • Patent number: 5200075
    Abstract: An adsorbent is charged into a horizontal type packed column having a multiplicity of packed vessels each of which is composed of a partition plate and a cylindrical body and which are connected through the partition plates, from an opening formed on the upper wall of each cylindrical body. Then, each opening is closed tightly with a detachable plug cover. The partition plate is provided with a first fluid passage through which a fluid is passed in the direction of the axis of the cylindrical body and a second fluid passage which is in communication with the first fluid passage, which extends toward the peripheral wall of the cylindrical body and which opens at the cylindrical body. This apparatus is suitable for use as a multiple-stage adsorption separator directed to a simulated moving-bed system.
