Claim 13

The cleaning system as recited in claim 9 wherein the array of transducers includes a plurality of transducers arranged so that the emitted beams collectively envelop the objects.

Claim 14

The cleaning system as recited in claim 9 wherein said vessel includes a longitudinal axis, said mounting members being spaced from each other along said longitudinal axis.

Claim 15

A static megasonic cleaning system for cleaning objects having a major plane, said system comprising: (a) a cassetteless vessel having a first end, a second end and four interconnected walls extending between said first and second ends, each of said walls having an internal surface, said internal surfaces defining an internal cavity for receiving the objects and a cleaning fluid; (b) a first mounting member extending inwardly from and directly mounted on said internal surface of one of said walls for engaging and supporting the objects within the cavity; (c) a second mounting member extending inwardly from and directly mounted on said internal surface of a second of said walls for engaging and supporting the objects within the cavity in combination with said first mounting member; (d) a first array of transducers mounted on said one of said walls outwardly of said internal surface thereof, each transducer of said first array emitting a focused beam of megasonic energy into said cavity generally parallel to the major plane of the objects and being mounted on said one of said walls such that the focused beam of energy passes directly from said internal surface of said one of said walls to said objects without impacting upon said first mounting member; and (e) a second array of transducers mounted on said second of said walls outwardly of said internal surface thereof, each transducer of said second array emitting a focused beam of megasonic energy into said cavity generally parallel to the major plane of the objects and being mounted on said second of said walls such that the focused beam of energy passes directly from said internal surface of said second of said walls to said objects without impacting upon said second mounting member.

Claim 16

A static megasonic cleaning system for cleaning objects having a major plane, said system comprising: (a) a cassetteless vessel having a first end, a second end and four interconnected walls extending between said first and second ends, each of said walls having an internal surface, said internal surfaces defining an internal cavity for receiving the objects and a cleaning fluid; (b) a first mounting member extending inwardly from and directly mounted on said internal surface of one of said walls for engaging and supporting the objects within the cavity; (c) a second mounting member extending inwardly from and directly mounted on said internal surface of a second of said walls for engaging and supporting the objects within the cavity in combination with said first mounting member; (d) a first array of transducers mounted on said one of said walls outwardly of said internal surface thereof, each transducer of said first array emitting a focused beam of megasonic energy into said cavity generally parallel to the major plane of the objects and being mounted on said one of said walls such that the focused beam of energy passes directly from said internal surface of said one of said walls to said objects without impacting upon said first mounting member; and (e) a second array of transducers mounted on said second of said walls outwardly of said internal surface thereof, each transducer of said second array emitting a focused beam of megasonic energy into said cavity generally parallel to the major plane of the objects and being mounted on said second of said walls such that the focused beam of energy passes directly from said internal surface of said second of said walls to said objects without impacting upon said second mounting member.
