Abstract: Based on initial position information on an instructed fixed switch-back point and position information on a loading point, a relative positional relationship between the loading point and the switch-back point is generated. If the position of the loading point moves, then based on position information on the position-moved loading point, information on a direction of an unmanned vehicle at the loading point and information on a relative positional relationship, a new switch-back point is set at a position where the relative positional relationship can be maintained. When the initial position of the switch-back point is instructed, then on the basis of the initial position information on the switch-back point, a driving path leading to the loading point via the instructed switch-back point is generated and, when the position of the loading point moves, a driving path leading to the position-moved loading point via the new switch-back point is generated.

Abstract: In a vehicular driving system and a driving method thereof in which a vehicle is driven toward a loading point, a waiting point is set on a driving path. The vehicle drives from an entry point of a loading site to the waiting point along the driving path, and stands by at the waiting point until permission is given by a loader. When there is an order to change the loading point when the vehicle is at the waiting point or driving to the waiting point, a partial driving path is created, and the vehicle drives from the waiting point to the new loading point along the partial driving path. When there is no order to change the loading point when the vehicle is at the waiting point or driving to the waiting point, the vehicle drives from the waiting point to the original loading point along the driving path.

Abstract: The present invention aims to provide a water faucet which allows a large space to be secured above the washing area and yet can deliver a high washing performance by landing streams or waterdrops having a large cross-sectional area evenly on a piece to wash. This water faucet includes a flow velocity changing part which changes the flow velocity of the stream discharged from each of multiple water spray holes such that the cross-sectional area of the stream changes with time. The multiple water spray holes are disposed at intervals such that, when the cross-sectional area of one stream discharged from one water spray hole exceeds a predetermined size, the one stream is merged with one of the other streams discharged from the multiple other water spray holes adjacent to the one water spray hole, and such that the one of the other streams with which the one stream merges changes with time.
