Abstract: A method for processing flat articles with acoustical energy. The inventive system method can remove particles from both sides of a wafer more efficiently and effectively. In one aspect, the invention is a method for processing flat articles wherein a liquid is applied to both major surfaces of the flat article. A first transducer assembly is positioned adjacent to a first of the major surfaces of the flat article and a second member is positioned adjacent to a second of the major surfaces. The first transducer assembly generates and transmits acoustical energy to the first major surface of the flat article while the second member either: (1) reflects the acoustical energy generated by the first transducer assembly back to the second major surface of the flat article; and/or (2) generates and transmits acoustical energy to the second major surface of the flat article.

Abstract: A spray cleaning device having an atomizing unit with at least one gas passage and at least one cleaning fluid passage converging into a atomizing area. The gas flowing though the gas passage and the cleaning fluid flowing through the cleaning fluid passages combine to form a mixture at the atomizing area. The accelerating unit has an acceleration passage for spraying the mixture onto a substrate surface. The gas passages are preferably angled with respect to the cleaning acceleration passage.

Abstract: A wafer cleaning system having a crystal or ceramic transducer assembly. The transducer assembly is adapted to convert electrical energy into sonic energy. The crystal or ceramic has a first conductive surface. The transducer assembly also has a transmitter made of an inert non-reactive plastic that transmits the sonic energy generated by the crystal or ceramic. The transmitter has a surface bonded directly to the conductive surface of the crystal or ceramic.

Abstract: A handgrip and leg brace assembly is located over a horizontal bench portion of a stretch bench that receives and supports a user's upper torso. The handgrip is adjustable in the horizontal and vertical planes as stretching exercises are on-going and without the user leaving the bench proper. Additional bench adjustments provide an individualized height setting, and these combined adjustments allow the bench to be personalized for each given individual in order to increase the effectiveness of certain on-the-bench stretching activities.

Abstract: A ramped and horizontal stretching bench for relieving spinal and muscle conditions contributing to back pain. More particularly a stretching bench that has moveable and adjustable settings for increasing the effectiveness of such relief. An arm brace and hand grip assembly is located under a horizontal bench portion that receives and supports a user's upper torso. The arm brace is readily adjustable as stretching exercises are on-going and without the user leaving the bench proper. Additional bench adjustments provide an individualized height setting, and these combined adjustments allow the bench to be personalized for each given individual in order to increase the effectiveness of certain on-the-bench stretching activities.
