Abstract: A low cost package uses non-ceramic materials to environmentally seal an air chamber for an electronic component. The package includes a base formed by a plurality of essentially flat terminals molded in a polyphenylene sulfide resin so as to provide a planar surface for surface mounting to a circuit board. A component placement area on the base receives a cap which covers and seals the area from contaminants.

Abstract: An improved pushrod for an impact printer or the like wherein the pushrod wire has a tip member at each end thereof, the outer ends of the tip members having a seat-forming, preferably conical, recess therein communicating with an underlying undercut cavity, a molded impact button being seated in the recess and filling the undercut cavity, the impact button having an outwardly projecting surface which is preferably flat. In a preferred embodiment the axial bore in the shank of the tip member communicates with the annular cavity and the undersurface of the impact button has a centrally disposed recess therein. The shanks of the tip members are preferably swaged to the pushrod wires at three or more angularly equal locations about the periphery of the shanks, the ends of the pushrod wires being roughened by grit blasting.

Abstract: A binding post terminal construction wherein the cylindrical body of the post terminates in an inwardly tapered annular shoulder, the end of the post having a conical recess therein, the post being divided into an opposing pair of tines by an arcuate slot, the arcuate slot cutting through the tapered shoulder and the conical recess to define a seat at the upper end of the post for receiving and positioning a straight length of lead wire to be inserted in the slot together with cam surfaces acting to bend the wire to conform to the configuration of the slot as the wire is displaced downwardly into the slot.
