Abstract: A vehicle brake system includes a switching valve switchable between a first state allowing communication between a first fluid pressure generating device and a frictional brake and a second state allowing communication between a second fluid pressure generating device and the frictional brake. The second fluid pressure generating device generates a fluid pressure by moving a piston with an electric actuator, and has a fluid pressure supply port connected to the switching valve and an atmosphere opening port connected to a reservoir tank. When, due to a failure, the switching valve becomes a third state in which the switching valve makes each of the first fluid pressure generating device and the second fluid pressure generating device communicate with the frictional brake, a control device controls the second fluid pressure generating device to close the atmosphere opening port with the piston.

Abstract: A movable discharge device for use in a particle/bulk material storage silo includes: a travel body configured to travel along a groove provided at a lower portion of a storage silo; a scrape-out unit configured to move integrally with the travel body and including a blade configured to rotate above the groove to rake coals in the storage silo and scrape out the coals to the groove; and a groove closing mechanism configured to close a predetermined region of the groove within a rotation trajectory region of the blade. The discharge device is configured to be able to suppress the change in the discharge amount of coals discharged by the blade from the particle/bulk material storage silo.

Abstract: Belt reversing mechanisms configured to reverse a belt at an upstream portion and a downstream portion of a return belt of a belt conveyor, includes two sets of pinch rollers spaced apart from each other in a belt movement direction and configured to support the belt, and two sets of guide roller mechanisms spaced apart from each other in the belt movement direction and are configured to guide the belt in a tubular shape from outside between the pinch rollers such that the belt is reversed 180 degrees and twisted to cause a center portion of a span between the pinch rollers so as to form a tubular open cross-section with a dirty surface facing inward; and the belt between the two sets of pinch rollers forms a catenary curve or a curve close to the catenary curve.

Abstract: Disclosed is a belt conveyor capable of greatly reducing friction resistance between side portions of a belt and troughs, comprising troughs (5), a belt moving above the troughs (5) along a longitudinal direction thereof, belt bending members (12) provided outside on both sides of the belt in the width direction so as to be located upstream of an entrance (5a) of the troughs, for abutting with both side portions of the belt to be bent upwardly, load cells (14) for detecting a reactive force exerted by the belt with which the belt bending members (12) make contact, guide rails (16) engaged to cause the belt bending members (12) to be displaced to be fixed at a desired position so as to bend the side portions of the belt or restore the bent belt, and rails (20) for moving the guide rails (16) along the longitudinal direction of the belt.
