Abstract

A tubular transducer is completely coated with a conductive material. A portion of the conductive material is removed forming an isolation band, which separates the outer electrode from the inner electrode. The bridged end provides a convenient electrical connecting point to the inner electrode. In order to apply an electrical potential across the tubular transducer from the outer to the inner surface, electrical connections must be made. An easy connecting method is shown. Two strips of copper-thin film Mylar printer circuit, each of total thickness 0.004 inch, are separated as shown by a 0.030 inch epoxy sheet. A hole is punched in the connecting structure of diameter 0.003 inch less than the O.D. of the transducer. A conical tool is used to form a "volcano" shaped rim of diameter 0.001 inch in diameter smaller than the O.D. of the transducer. The transducer is then pushed into place as shown. The whole structure can then be encapsulated. The tubular transducer can be used, e.g., as an ink jet ejector.
