Patent number: 6251692Abstract: A semiconductor processing workpiece support which includes a detection subsystem that detects whether a wafer or other workpiece is present. The preferred arrangement uses an optical beam emitter and an optical beam detector mounted along the back side of a rotor which acts as a workpiece holder. The emitted beam passes through the workpiece holder and is reflected by any workpiece present in the Workpiece holder. The preferred units include both an optical emitter and pair of detectors. The detection is preferably able to discriminate on the basis of the angle of the reflected beam, so that a portion of the beam reflected by the workpiece holder is not considered or minimized.Type: GrantFiled: September 1, 1999Date of Patent: June 26, 2001Assignee: Semitool, Inc.Inventor: Kyle M.

Patent number: 5881980Abstract: An adjustable leg assembly comprises an outer tube and an inner tube subassembly. The inner tube assembly comprises an inner tube, a floor support at one end of the inner tube, an expandable bushing at an opposite end of the inner tube, a rod extending through the inner tube and secured to the bushing and threadedly engaged with the floor support. The inner tube subassembly is inserted into the outer tube such that the bushing is confined within the outer tube and can be expanded into and retracted from contact with the outer tube by turning the floor support relative to the inner tube. In the preferred embodiment illustrated in the drawings, the floor support is a glide/tightener that provides a floor glide to support the leg assembly and that provides a tightener that is threadedly engaged with the bushing rod.Type: GrantFiled: June 27, 1997Date of Patent: March 16, 1999Inventor: Edward C.

Patent number: 5813131Abstract: The invention comprises a pair of telescopic sight mount aligning bars. Each bar comprises an elongated rod having a planar circular inner end bounded by a circular peripheral edge. The circular inner ends of the two bars are perpendicular to the longitudinal axis of their respective bars, and the inner ends of the two bars have substantially identical diameters and peripheral edges so that the two inner ends may be closely juxtaposed when used to align, and to check the alignment of, a telescopic sight mount. Consequently, a telescopic sight mount misalignment will be revealed by a misalignment of the peripheral edges relative to one another and also will be revealed by a non-parallelity between the two inner ends.Type: GrantFiled: October 2, 1995Date of Patent: September 29, 1998Inventor: John D.
