Abstract: An information distribution apparatus includes an obstacle identification apparatus that identifies an obstacle to a vehicle traveling in an area and then outputs obstacle information related to the position of the obstacle, a road database representing the positions of roads, and an impassable-road determination means that determines a road through which the vehicle cannot pass, based on the obstacle information outputted from the obstacle identification apparatus and the road database, and then outputs impassable-road information. A narrow-area automatic driving system is provided with the information distribution apparatus and the vehicle that travels from a departure point to a target point, along a route formed based on information outputted from the information distribution apparatus.

Abstract: An apparatus for producing a battery case which has a tubular shape with a closed end and which houses an electricity-generating element, the apparatus including: a die assembly including a blanking die, a drawing die, a redrawing die and an ironing die which have respective die holes having mutually different sizes and which are immovably and coaxially arranged in series in the order of the sizes of the die holes; a first punch, a second punch and a third punch which are disposed coaxially with respect to the die assembly such that the first through third punches can be inserted into the corresponding die holes of the respective dies; and a moving mechanism which permits the first through third punches to be inserted into the corresponding die holes.
