Title:
LAMINATED DISPLACEMENT ELEMENT AND MANUFACTURE THEREOF
Document Type and Number:
Japanese Patent JPH0529680
Kind Code:
A
Abstract:
PURPOSE:To prevent an electric connection defect, a mechanical wire disconnection by allowing an alloy layer which is scarcely oxidized of a material for constituting a stripe to remain, and removing plated metal which is easily oxidized. CONSTITUTION:Side of a laminate for constituting a stripe 5 is coated with glass powder paste, and baked to form an insulating layer 7. The surface is lapped to expose part of the stripe 5. Temporarily provided external electrodes 13, 14 are connected to a positive, a counter nickel electrode is connected to a negative, and a DC current flows to perform an electrolytic etching. Thus, a nickel layer 5b coating the outer periphery is removed except an allow layer 5a for constituting the stripe 5 to form a cavity. A laminate block is cut into a plurality to single elements, external electrodes are then provided, and a laminated displacement element is formed. Accordingly, in addition to a large contact surface area, a so-called 'anchoring action' can be expected, and hence cutting, peeling by an external force can be sufficiently prevented.
