  • Patent number: 10309352
    Abstract: An intake manifold includes a plurality of intake pipes that are provided in line to send air to an engine mounted on a vehicle through the intake pipes. Each of the intake pipes includes a main body formed of resin and an end pipe formed of resin, welded to a lower stream end side of the main body, and joined to the engine. Further, one member of the main body and the end pipe is provided with a rib that is formed on a side surface portion of the one member and that extends toward a lateral side of the other member. The other member is provided with a restriction portion that is formed on a side surface portion of the other member and that interferes with the rib to restrict moving of the main body in the crash direction relative to the end pipe when a weld portion of the main body and the end pipe is broken due to a collision load applied to the intake pipe at a vehicle crash.

  • Patent number: 9915928
    Abstract: An availability prediction apparatus includes an access section that accesses a storage section and a prediction section. The storage section stores availability specified periods occurred before a present time associated with respective frequencies of the availability specified periods, and the access section acquires the availability specified periods from the storage section. The prediction section predicts at least one target availability specified period within a prediction term, which begins at the present time and ends at a time later than the present time by a predetermined term. The prediction section includes a correlating section that correlates the availability specified periods with candidate periods included in the prediction term, and a selection section that specifies and selects one of the candidate periods having a highest occurrence probability as the target availability specified period.

  • Patent number: 9597975
    Abstract: A power supply system for supplying a grid power to a building includes a power generator, a power storing device, and a power controller. The power generator generates off-grid power from a predetermined energy. The power storing device stores the grid power and the off-grid power and supplies the stored power to the building. The power controller controls consumptions of the grid power and the off-grid power. The power controller calculates predicted consumption data related to power consumed in the building and predicted generation data related to power generated by the power generator. The power controller calculates a charging-discharging schedule for the power storing device based on the predicted consumption data and the predicted generation data by formulating the charging-discharging schedule as a mixed integer programming problem.

  • Patent number: 8490567
    Abstract: Apparatus for coupling a pushboat to a barge having a notch in its stern for receiving the bow of pushboat. The pushboat has three coupler units, two on the opposite sides and one at the bow end, each of which has an extensible and retractable connecting pin. The side connecting pin has hemi-spherical part at its outer end part which comes into tight contact with the similar hemi-spherical part of the holes in side socket on the side wall of the notch when it is extended out and inserted into the hole for connection. The bow connecting pin has wedge-shaped end which engages with the teeth of the center rack located in the barge's centerline at the deepest point of the notch when it is extended out for connection. The motions of connecting pins are remotely controlled from a control panel located in the navigation bridge.

  • Patent number: 5050522
    Abstract: An apparatus is disclosed for connecting a pusher boat and a barge, having a notch in the stern portion for receiving the hull of the pusher boat, such that a three-point supported rigid connection is formed which utilizes three axially movable connecting pins. One of the pins is mounted at the bow end of the pusher boat to form a multi-step tooth-engagement with a centerline pin-end receiving member consisting of concavities arranged along the barge's centerline at the deepest point of the notch. The other two pins are mounted on opposing sides of the pusher boat to form a combined friction- and multi-step tooth-engagement with side-pin-end receiving members defined by vertical slots, in the side walls of the notch, with concavities arranged along the centerlines of the slots' base surfaces.
