Abstract: An article transport facility includes a transport vehicle configured to travel on a travel surface on each of a plurality of travel floors. The transport vehicle is configured to travel straight and to change directions by executing turning movement to turning about an axis in the up-down direction on a spot. Columns extend through the travel floors in the up-down direction and protrude upward of the travel surface. Each travel floor has column through holes that are for the columns to extend through. The column through holes do not overlap a first straight path, a second straight path, and a turning path as viewed in the up-down direction, and overlap at least either a first tangent line or a second tangent line.

Abstract: An article transport facility includes support columns (2) and support beams (5) that are coupled to the support columns (2) and support rails (7). The support beams (5) each include a beam body (50), attachment members (55) for attachment to the support columns (2), and support members (60) that are fixed to the beam body (50) and are for supporting the rails (7). A support beam (5) and a support column (2) are coupled together by locking portions (59) provided on the attachment members (55) being locked to lock receiving portions (21) formed in the support column 2, and by binding with use of first binding members (B1) inserted through first through holes (66) formed in the support members (60).

Abstract: According to an aspect of the present disclosure, there is provided a washing device that washes a barrel tank of a horizontal centrifugal barrel polishing device. The washing device includes a casing, a rotation mechanism, a washing nozzle, and a nozzle moving mechanism. The casing includes a frame to accommodate the barrel tank, and a rotary shaft extending from the frame. The rotation mechanism is a mechanism to rotate the frame around the rotary shaft. The washing nozzle is a nozzle to eject washing water. The washing nozzle is configured to be insertable into and removable from the barrel tank. The nozzle moving mechanism moves the washing nozzle in a direction where the washing nozzle is inserted into and removed from the barrel tank.

Abstract: The gateway apparatus for SNMP/OSI management enables that an SNMP manager manages an OSI management agent, by using a basic conversion of a management operation and a management information between SNMP and CMIP and by using a cache, a replica and a link object.
