Abstract: The means for securing weight plates (16) on weight rods (10?, 12) or holder bars provides at least one groove (14) formed in an end region (10?) of a weight rod (10?, 12) or in the holder bar. The weight plates (16) are formed with a radial protrusion (17) in their central bore, preferably extending over only a portion of the circumference. The diameter of the bore at the protrusion (17) is greater than the diameter of the end region (10?) of the weight rod (10?, 12) or holder bar axially next to the groove (14). The protrusion (17) falls into the groove (14) and prevents the weight plate (16) from slipping off the weight rod (10?, 12) or holder bar.

Abstract: A device and method for treating the surface of a semiconductor wafer provides a treatment fluid in the form of a dispersion of gas bubbles in a treatment liquid generated at acoustic pressures less than those required to induce cavitation in the treatment liquid. A resonator supplies ultrasonic or megasonic energy to the treatment fluid and is configured to create an interference pattern in the treatment fluid comprising regions of pressure amplitude minima and maxima at an interface of the treatment fluid and the semiconductor wafer.

Abstract: The present invention relates to an ultrasound actuator for cleaning objects, having a propagation volume (3,4,13) for ultrasound, on which one or more ultrasonic transducers (5) are arranged. The propagation volume (3,4,13) is delimited by an acoustic coupling-out window (8) with a coupling face for acoustically coupling an object (1,12) to be cleaned and by one or more reflection faces (6,7) for coupled-in ultrasound. The ultrasonic transducers (5) are arranged on the propagation volume (3,4,13) such that the coupled-in ultrasound exits the propagation volume (3,4,13) via the coupling-out window (8) only after one or more reflections at the reflection faces (6,7). The reflection faces are designed such that a predeterminable distribution of the ultrasound energy without intensity peaks results at the coupling-out window (8). The present ultrasound actuator is used to achieve gentle cleaning of the objects with economic use of cleaning liquid.

Abstract: The invention concerns a homogenous, in particular multicolored plastic sheet or panel, based on ethylene vinyl acetate copolymer (EVA) as binder with a filler content of 30 to 80 wt. % and a process for producing it. In other embodiments the binder contains, in addition to the 70 to 85 wt. % of EVA, polypropylenes to improve the processability (tendency to adhere), EPDM to improve the flexibility, and polyethylenes to reduce the tendency to soiling. In the process described, several additives, each consisting of a binder containing at least some ethylene vinyl acetate copolymer, up to 80 wt. % of fillers and up to 5 wt. % of pigments, are mixed, plasticized and granulated or comminuted to form granules or chips of assorted colours which are mixed and, possibly after other processing operations, pressed to form the plastic web or plates.
