Abstract: An aseismatic device applied to an overhead hoist transport (OHT) system in a fab has a spring pin and a positioning ball installed in a cavity of a first platform. The spring pin has at least a spring for fixing the positioning ball and is mounted on a second platform positioned on the surface of the first platform. When the earthquake occurs, the second platform will move horizontally corresponding to the first platform for preventing the OHT system and the fab from being damaged.

Abstract: An automatic transporting system and a method for operating the same. The automatic transporting system includes a main track, a plurality of transport vehicles, a loading and unloading track, a stocker, a rapid track and an emergency track. The plurality of transport vehicles move on the main track. The loading and unloading track has a first entrance and a first exit. The first entrance and first exit are connected to the main track. The stocker is disposed beside the loading and unloading track. The transport vehicles enter the loading and unloading track and stop at the stocker to load and unload a material. The rapid track has a second entrance and a second exit. The second entrance and second exit are connected to the main track. The emergency track is connected to the main track. The transport vehicles leave the main track via the emergency track.
