Method for determining a substrate position in a closed chamber and apparatus for performing the method
The present invention relates to a method and an apparatus for determining the position of a substrate within a closed chamber, wherein the substrate is moved within the chamber by a transport system comprising at least one rotating shaft. A load-converting element is provided adjacent to at least one of the rotating shafts, wherein the load-converting element detects a load acting on the at least one rotating shaft and converts it into an electrical parameter. While no substrate is present on the at least one rotating shaft, a first output signal corresponding to a first value of the electrical parameter is measured. The output signal is then monitored and a presence of the substrate on the at least one rotating shaft is detected when the output signal differs from the first output signal by at least a predetermined amount.
Stacker crane
In a stacker crane, a cover to cover an elevation area of an elevation portion is integrally attachable to side surface portions of a mast, which includes a reinforcement portion and an adjuster. The reinforcement portion between a pair of the side surface portions in a Y direction extends toward an opposite direction to an elevation surface of an elevation surface defining portion and has a higher stiffness than that of each of the pair of side surface portions. The adjuster is spaced from the elevation surface defining portion in an X direction perpendicular to a Z direction and the Y direction, and both edges thereof extendible in the Y direction are contactable with the reinforcement portion and each of the pair of side surface portions.
