Coating Apparatus U.S. Patent 5,529,627. June 25, 1996 B. Ocker and M. Saunders, assignors to Leybold AG, Hanau, Germany A coating apparatus comprising a sput- tering cathode bearing a set of magnets and disposed within a coating chamber, Ultrasonic Cleaning of Interior Surfaces U.S. Patent 5,529,635. June 25, 1996 D.M.C. Odell, assignor to The United States of America as represented by the United States Department of Energy, Washington A method for cleaning an interior sur- face of a tube having a first end and an opposing second end comprising coupling an ultrasonic wave generator to the first end of the tube; coupling a sound reflector to the second end of the tube, said sound reflector and ultrasonic wave generator be- ing spaced a distance apart; filling the tube with a fluid; generating an ultrasonic stand- ing wave in the fluid causing cavitation at the nodes; and moving the nodes with re- spect to the tube by varying the distance between the ultrasonic wave generator and the sound reflector. Mechanically Joined Sputtering Target U.S. Patent 5,529,673. June 25, 1996 D.P. Strauss et al., assignors to Sony Corp., Tokyo and Materials Research Corp., Orangeburg, N.Y.
