摘要： A leading edge of a blade has a first curved portion provided with a leading-edge rearmost point, and a trailing edge of the blade has a second curved portion located on the inner circumferential side of the trailing edge and a third curved portion located on the outer circumferential side of the blade on the trailing edge. The third curved portion has a trailing-edge foremost point, and the second curved portion has a trailing-edge rearmost point. The trailing edge and a first concentric circle, which is one of concentric circles having as their center an axis of rotation and passes through the leading-edge rearmost point, intersect each other at a first intersection. The first intersection is located between the trailing-edge rearmost point and the trailing-edge foremost point.

摘要： A first on-board device installed on a first train controls an emergency brake unit. When it is determined that an actual deceleration value is insufficient in comparison with a predetermined emergency brake reference deceleration value, the first on-board device predicts a first stop location based on the actual deceleration value, and sends, to a ground control device, a first signal indicating insufficient deceleration and a first stop location signal representing the first stop location predicted. The ground control device sends the first signal and the first stop location signal to a second on-board device of a second train traveling ahead of the first train. The second on-board device invalidates a preset first run curve, over a range from a second train location representing an on-track location of the second train to a stop limit location of the second train, and generates a second run curve to control the second train.

摘要： A train wireless system includes a train detecting apparatus on the ground and a controller on a train. The detecting apparatus includes a detector and a calculator. The detector detects that the train is on rails in a block. The calculator measures an on-rail time during which the detector detects the train in the block, and calculates an on-rail detecting time during which the train has been on the rails in the block. The controller includes a distance measurer, a time measurer, a recorder, and a train-length calculator. The distance measurer measures a travelling distance of the train from a beginning of the block, the time measurer measures an elapsed time since the distance measurer starts the measurement, the recorder records the elapsed time and the travelling distance, and the train-length calculator searches the recorder based on the detecting time, and calculates the train length using a selected travelling distance.

摘要： In an axial flow fan according to the present invention, a plurality of blades rotate about a rotation axis of the blades to convey a fluid. In the axial flow fan, the plurality of blades each have a leading edge at a leading side in a rotational direction, a trailing edge at a trailing side in the rotational direction, and an outer peripheral edge connecting the leading edge and the trailing edge. The leading edge of one of the plurality of blades and the trailing edge of another blade adjacent to the leading edge of the blade in the rotational direction are connected by a plate-shaped connection portion. The plurality of blades each have at least one plate-shaped reinforcement rib extending from a periphery of the rotation axis toward the outer peripheral edge of the blade.
