摘要： A laminate displacement device comprises a laminate body having a plurality of thin plates made of an electromechanical converting material and a plurality of internal electrodes made of conductive material superposed on each other. The internal electrodes are used for every other electrode alternately as electrodes of first and second conductivity type, respectively. A first insulating layer is formed on one side surface of the laminate body so that the internal electrodes used for the electrodes of first conductivity type are exposed. Further a second insulating layer is formed on another side surface of the laminate body so that the internal electrodes used for the electrodes of second conductivity type are exposed. A pair of external electrodes are formed on the first and second insulating layers, which bridge the internal electrodes used as the electrodes of first and second conductivity type, respectively. The insulating layers are made of a crystalline inorganic material containing Pb converted into PbO of 5.0 to 45.0 wt. %.

摘要： A laminated displacement device comprises: a laminate which is formed by alternately laminating thin plates made of an electromechanical converting material and internal electrodes made of a conductive material; and external electrodes which are provided in the side portions of the laminate and are connected to the internal electrodes. In the laminated displacement device, a plane projection area which is obtained by overlapping the internal electrodes in the laminating direction is set to be smaller than a plane projection area which is obtained by overlapping the thin plates in the laminating direction. A relation of B/A.gtoreq.0.5 is satisfied between the width dimension A of a displacement portion which is formed by overlapping the projections of the internal electrodes in the laminating direction and the width dimension B of a non-displacement portion which is formed between the edge of the displacement portion and the side surface of the laminate.

摘要： A method of making a layered electrostrictive displacement device by forming sheets of an electrostrictive material alternately with internal electrodes. The laminate formed therefrom has two opposite surfaces at which the ends of the internal electrodes are exposed and two other opposite surfaces at which alternate layers of the internal electrodes are exposed. Temporary external electrodes are formed on the latter mentioned opposite surfaces. Alternate layers of the exposed portions of the internal electrodes are plated at one surface of the laminate with a metal while using a temporary external electrode as a cathode. The exposed portions of the other internal electrodes are plated with metal using another temporary external electrode as a cathode. The non-plated portions of the plated surface are selectively removed to form recesses, and an insulating film is formed on the recesses. Portions of insulating film and the metal deposited are removed to expose the internal electrodes, and external electrodes for connection to the exposed internal electrodes are formed.
