  • Patent number: 10293842
    Abstract: An on-board device is loaded in a moving vehicle and includes a control device configured to control the traveling of the moving vehicle. In the control device, an in-field traveling instructing section determines whether a blockade moving vehicle exists to hinder the traveling of the moving vehicle on a traveling route to an inspection field in a railyard, based on different moving vehicle related data in the railyard when the moving vehicle is an inspection waiting vehicle. A traveling route securing section requests securement of the traveling route to a railyard interface device that controls branching on the traveling route when there is not the blockade moving vehicle on the traveling route. A traveling permission section permits the traveling of the moving vehicle on the secured route based on traveling route state data from the railyard interface device.

  • Patent number: 9670658
    Abstract: A switching mechanism is configured to switch an advancing direction of water injected from a nozzle by moving between a first position and a second position. The switching mechanism is held at the second position by a force received from the water injected by the nozzle during the tank water feeding process. A refill mechanism has a refill pipe for causing the water injected from the nozzle during the tank water feeding process and whose advancing direction is switched by the switching mechanism to flow in through an inflow port on one end side. The refill pipe is configured to lead the water having flowed in through the inflow port to a toilet stool body without flowing through a suction port of a throat pipe.
