摘要： An additive manufacturing apparatus includes a shaping part, a powder feeding part that feeds the powder material to the shaping part, a powder storage part that stores the powder material, and a pipe through which the powder material is transferred from the powder storage part to the powder feeding part. The powder storage part is arranged on a lower side of the powder feeding part in the vertical direction. The pipe is provided with a bent part in a transfer section in which the powder material is transferred from a lower side to an upper side in the vertical direction. The bent part stops the falling of the powder material that is present in the transfer section in the middle of the transfer section when the suction is stopped.

摘要： An overhead-line using system includes: a plurality of supports; a main rope supported by the supports and configured such that both ends of the main rope are fixed; a work rope movably supported by the main rope; a winding device configured to wind up the work rope; a moving device movably supported by the main rope and connected to the work rope, the moving device being movable in the air when the work rope is wound up by the winding device; and a power generator configured to move along with movement of the work rope. The power generator generates electric power by moving relative to the main rope.

摘要： An overhead line system includes a plurality of support posts, an overhead line supported by the support posts, a lifting device with which the overhead line is liftable, a suspension device that is connected to the overhead line and is movable in the air as the lifting device winds the overhead line, and a control device. The control device controls the lifting device so as to reduce tension when a predetermined condition relating to a tension abnormality of the overhead line is satisfied.
