Abstract: A wheel frame for a hollow foam wheel includes a hollow foam tire which has two opposing bulged inner rims to form a housing space therebetween, two opposing wheel frames located on two outer sides of the foam tire each having a jutting outer rim. The jutting outer rim has an inner side with spikes located thereon and an inner peripheral surface which has first ridges formed thereon. The housing space holds a plurality of retaining members assembled in an annular manner. Each retaining member has a flange on the inner rim thereof with second ridges formed on the inner peripheral surface to mate alternately the first ridges of the wheel frame. The two wheel frames are screwed towards each other to clamp the foam tire securely between the jutting outer rim and the retaining members. The spikes on the inner side of the wheel frame pierce into the foam tire for anchoring. Thus the hollow foam tire may be coupled and anchored securely and provide an improved elastic and cushion effect.

An electric tool housing is formed with a through hole corresponding to the carbon brush seat for passage of the carbon brush. A sunken space is formed around the through hole for embedding the carbon brush seat. The outer edge wall of the sunken space may just insertably grip the edge of the cover such that the cover forms a part of the housing after assembly to shield the carbon brush seat embedded in the housing. By virtue of the constant force spring, the carbon brush can be subjected to a more uniform biasing action to thereby prolong the service life of the carbon brush.

Abstract: An interlock system prevents collision of handling equipment and damage to wafers in an automated wafer transport apparatus during manual control by an operator. Sensors are used to sense when wafer transport arms and wafer stage are both in their home positions. A controller is responsive to the sensors for operating the lockout system such that attempted activation of the transport arm by the operator is locked out unless both the stage and the arms are in their home positions. The lockout system preferably comprises normally closed electrical relays.

Abstract: The present invention discloses an allocation method for establishing a theoretical dispatching model for dynamically allocating the bottleneck resource according to the on-line current data. At first, the on-line current data are obtained from the bottleneck resource and those tools next to the bottleneck resource. Decision parameters such as the remaining processing time, buffer WIP of the tools next to bottleneck resource are sequentially derived by using the current data. Each tool next to the bottleneck resource is then determined to receive additional lots from the bottleneck resource or not. Finally, the bottleneck resource is reallocated to those tools that requires the lots from the bottleneck resource.
