Abstract: A beverage holder attachment for a crutch has an annular cup holder portion and two molded C-shaped protrusions for snapping onto two side rails of a crutch. The cup holder has a vertical slot on the outside to accommodate a handle of a mug or cup. The cup holder sits in between the two rails of the crutch below the hand bar so that it does not interfere with the use of the hand bar. The cup holder is tilted slightly to avoid spillage on the user of the crutches, so that any coffee drips will spill on the outside of the crutch. The beverage holder can be snapped onto the crutch side rails to carry beverages or other objects around the home or office while on crutches. The beverage holder can be made out of plastic, rubber or any other molded material that will snap onto the crutch.

Abstract: An artificial turf field comprises a mat with artificial grass stitched to the mat and rubber granules combined with powdered latex or other suitable powdered binding agent activated by water. Mats with the artificial grass affixed are laid on an athletic field. Rubber granules mixed with a bonding agent and the coated rubber granules are poured over the mats and raked until a depth of ½ to ¾ inches is achieved. Water is then misted onto the surface activating the bonding agent. The first layer is allowed to set. The first level of infil material will be bound particle to particle, to the grass and to the mat by the agent, thus ensuring a stablized shock absorbency pad. Additionally, the stabilized layer eliminates substantial migration of loose infil material.

Abstract: A semiconductor wafer is provided with magnetic material about the periphery for magnetically clamping the wafer on a seating gasket at the processing station. The seating gasket is annular for peripherally supporting the wafer. An electro-magnet establishes a peripheral station magnetic field which attracts the wafer magnetic material to form the clamp. The station magnetic field may by reversed to levitate the wafer onto and off of the seating gasket.

Abstract: A method and apparatus are described for inhibiting visual obstruction of the window of a semiconductor etch process chamber by deposition of each byproducts thereon by selectively heating the window surfaces adjacent one edge of the window to thereby form a cool region on the window surfaces adjacent the opposite edge of the window whereby the center of the window will remain substantially clear of such depositions. The apparatus for carrying out the method of the invention comprises a first heat transmitting structure disposed on one surface of an optically transparent window adjacent one edge, and a second heat transmitting structure disposed on the opposite surface of the optically transparent window adjacent the same edge to thereby provide even heating of both surfaces of the window adjacent the one edge, thereby creating a cooler zone on the window surfaces adjacent the opposite edge of the window.
