Abstract: A fixing device includes a fixing member, a pressure member, and a pair of retention members each including a restriction surface. The restriction surface restricts a movement of the fixing member in an axial direction. The restriction surface includes a first contact area and a second contact area. The first area is an area more on a downstream side of a passing direction of a medium than a center of a pressure area in the passing direction, and also closer to the pressure area than an apex of the fixing member on an opposite side of the pressure area. The first contact area and the second contact area are each tilted at a certain gradient so as to be set apart from the end portion of the fixing member in the axial direction from a side of the apex toward a side of the pressure area.

Abstract: A differential case (23) is therein provided with a plurality of rotating discs (38) that are spline-coupled to an outer peripheral side of aright side gear (35), and a plurality of non-rotating discs (39) that are respectively arranged between the respective rotating discs (38) and are non-rotatable relative to the differential case (23) and are movable in a left-right direction. A pressure ring (43) that presses the non-rotating discs (39) toward the rotating discs (38) is disposed between a right retainer (41) positioned in the right side gear (35)-side and the non-rotating disc (39). The right retainer (41) is therein provided with a piston accommodating part (41D) in a position facing the pressure ring (43) in the left-right direction. The piston accommodating part (41D) is therein provided with a piston (46) that is displaced by hydraulic pressure to press the non-rotating discs (39) against the rotating discs (38) through the pressure ring (43).

Abstract: A radio train control system controls the trains on tracks on which track circuits are built, and includes: ground radio devices performing radio communication with the trains and acquiring position information of the trains; field devices acquiring track circuit state information indicating whether the track circuit is ON or OFF; ground base devices receiving the position information and the track circuit state information and transmitting control information to the trains; and an on-track vehicle control device receiving the position information and the track circuit state information and managing on-track information. The ground radio devices and the field devices have transmission paths connected with the on-track vehicle control device without the ground base devices, and the on-track vehicle control device can transmit the control information to the trains through the transmission paths when the ground base device is out of order.

Abstract: A roll detector mounted on a train includes: a sensor that detects a movement of the train while the train is not in operation with an on-board controller being inactive, the on-board controller controlling an action of the train; and a roll sensor that determines whether or not the train has rolled on the basis of a result of the detection by the sensor, and performs train protection when determining that the train has rolled.
