  • Publication number: 20220022387
    Abstract: In an overhead line system, a first moving device is movable in the air between a first support post and a second support post. A first overhead line is stretched from the first moving device and connected to the first lifting device via the first support post. A second overhead line is stretched from the first moving device and connected to the second lifting device via the second support post. A second moving device is movable in the air between a third support post and a fourth support post. A third overhead line is stretched from the second moving device and connected to the third lifting device via the third support post. A fourth overhead line is stretched from the second moving device and connected to the fourth lifting device via the fourth support post. A suspension device is connected to the first moving device and the second moving device.

  • Publication number: 20220024713
    Abstract: 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.

  • Patent number: 10173263
    Abstract: 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.
