Abstract: An apparatus for carrying cargo on a roof of a recreational vehicle which has a rooftop air conditioning unit is provided and has a space or well that is configured for receipt of the rooftop air conditioning unit therein. The cargo carrier may have cargo-receiving spaces in front of, in back of, and alongside the air conditioning unit. An upper frame member of the cargo carrier may provide a mounting area that is above or even with a top of the air conditioning unit.

Abstract: A system for processing wafers includes a robot moveable within an enclosure to load and unload workpieces into and out of workpiece processors. A processor includes an upper rotor having alignment pins, and a lower rotor having one or more openings for receiving the alignment pins to form a processing chamber around the workpiece. The alignment pins center the workpiece relative to a rotor spin axis and to an etch or drain groove in the upper rotor. A first fluid outlet delivers processing fluid to a central region of the workpiece. The processing fluid is distributed across the workpiece surface via centrifugal force generated by spinning the processing chamber. Purge gas is optionally delivered into the processing chamber through an annular opening around the first fluid outlet to help remove processing fluid from the processing chamber.

Abstract: A system and method for processing a workpiece, includes workpiece processors. A robot is moveable within an enclosure to load and unload workpieces into and out of the processors. A processor includes an upper rotor having a central air flow opening. The upper rotor is magnetically driven into engagement with a lower rotor to form a workpiece processing chamber. A moveable drain mechanism aligns different drain paths with the processing chamber so that different processing fluids may be removed from the processing chamber via different drain paths. A moveable nozzle positioned in the air flow opening distributes processing fluid to the workpiece. The processing fluid is distributed across the workpiece surface, via centrifugal force generated by spinning the processing chamber, and removed from the processing chamber via the moveable drain mechanism.
