Abstract: A clinch-in fastener with a cylindrical body having a top, a bottom, sides and an axial internal bore. The fastener has a single shank at the bottom end of the body having a top surface orthogonal to the bore and a chamfer tapering to the bottom of the body. The top surface of the shank is adapted for receiving the cold flow of material surrounding a receiving hole of a workpiece. The shank may have a plurality of notches in its outermost edge that extend through both the top surface of the shank and the chamfer. The bore of the fastener extends completely through the fastener body from top to bottom and may be threaded. A fastener installation system having a tool with means for affixation to a rotary and vertically reciprocal element of an industrial machine. The tip of the tool has a distal end face with at least one arcuate displacer adapted for deforming a workpiece as the tool rotates and is pressed against the workpiece. A bore within the tip holds a fastener installed by the tool.

Abstract: A deposition apparatus comprises: an infeed chamber; a preheat chamber; a deposition chamber; and optionally at least one of a cooldown chamber and an outlet chamber. At least a first of the preheat chamber and the cooldown chamber contains a buffer system for buffering workpieces respectively passing to or from the deposition chamber.

Abstract: A video game joystick controller is disclosed which includes a lower housing which defines a lower convex bearing surface, an upper housing which defines an upper concave bearing surface concentric with the lower bearing surface, and a handle which defines inner and outer bearing surfaces. The inner bearing surface of the handle is adapted to mate with the lower bearing surface of the lower housing, and the outer bearing surface of the handle is adapted to mate with the upper bearing surface of the upper housing such that the handle is free to pivot with a smooth action. A plate is mounted to the lower end of the handle, and this plate bears four switch actuators, one of which is higher than the other three. A circuit board is mounted to the upper housing, and it serves to mount four coplanar switches, each of which is situated directly above a respective one of the four actuators.

Abstract: A speaker apparatus which has a main speaker and at least one tweeter speaker in which a wire bridge member is used to support the tweeter speaker relative to the main speaker at a predetermined position therefrom. The wire bridge member is retained between the tweeter speaker and the tweeter speaker cover by pins which are heat staked. The wire bridge member has a circular center portion to accommodate the tweeter speaker and arm portions extending transversely and then inwardly at right angles for securing to the main speaker.
