A specific transfer mode is a mode for causing a transport device to execute a first transfer operation, a travel operation, and a second transfer operation in this order. The first transfer operation is transferring a second article from a storage region to the transport device with use of a second transfer device, and thereafter transferring a first article from the storage region to the transport device with use of a first transfer device. The travel operation is traveling to a position corresponding to a boundary between a relay section and a temporary placement region while holding the first article and the second article. The second transfer operation is transferring the first article from the transport device to the relay section with use of the first transfer device, and transferring the second article from the transport device to the temporary placement region with use of the second transfer device.

Article storage facility

An unloading priority mode is a mode for causing a transport device to execute a first transfer operation, a second transfer operation, a first travel operation, a third transfer operation, and a second travel operation in this order. The first transfer operation is an operation of transferring a second article to the transport device. The second transfer operation is an operation of transferring a first article to the transport device. The first travel operation is an operation of traveling to a position corresponding to a relay section while holding the first article and the second article. The third transfer operation is an operation of transferring the first article to the relay section, and thereafter transferring a third article to the transport device. The second travel operation is an operation of traveling to a position corresponding to a storage section while holding the second article and the third article.

A spot repair method of scratch-resistant paint film: (a) sanding a part to be repaired having a scratch-resistant clear paint film thereon, (b) sanding a part to be clear gradation painted outside the part to be repaired with an abrasive material, (c) painting the part to be repaired with a color base-paint, (d) applying a clear paint wet-on-wet without curing the color base-paint, (e) applying a clear paint diluted with a gradation agent to the part to be gradation painted, (f) drying the applied paints, and (g) polishing the dried parts, wherein (1) the clear paint is a two-liquid type having an isocyanate curing agent and (2) the gradation agent comprises from 5 to 50 mass % ethyl ethoxypropionate, from 1 to 5 mass % of an acrylic resin as solid fraction, a surfactant and a curing catalyst.
