Abstract: An electromechanical actuator structure is disclosed to include an electric actuator affixed to a base, a resilient drive member, which has a fixed segment fixedly connected to the electric actuator for synchronous reciprocating movement and a resilient segment extending out of the electric actuator and terminating in a conduction portion, a passive member mounted in the conduction portion of the resilient drive member, and a spring member mounted on the resilient segment of the resilient drive member and forcing the passive member into friction engagement with the conduction portion for enabling the passive member to be moved with the resilient drive member. By means of the amplitude of oscillation produced by the resilient drive member during displacement, the amount of displacement of the passive member is enlarged, and therefore the displacement speed of the passive member is increased and the working frequency of the drive pulse is lowered.

Abstract: A lid or cover for a ceramic enclosure is formed of a substrate of an iron-based alloy, e.g., Kovar, alternately plated and coated with electrolytic nickel and electroless nickel, with an outer gold electroplate. The alternate electroplate and electroless nickel layers render the lid highly corrosion resistant without the need for an expensive, unrecoverable buried gold layer.

Abstract: A lid for closing an electronics package exhibits a high corrosion resistance. The lid is formed of a metal substrate which is clad with rolled or worked nickel, and covered with a layer of gold or precious metal electroplate. At edges of the lid, which are not covered with cladding, a layer of nickel is electroplated, employing the dogbone effect to concentrate the metallization at the edges. The rolled or worked metal has a much smaller porosity than an electroplated layer, and the nickel cladding can be applied to the desired thickness in much less time than nickel electroplate.
