A dielectric substrate having an embedded inductor wherein each turn of the inductor traverses several layers such that the top and bottom of each turn of the inductor are parallel to each other but are in different layers and the sides of each turn of the inductor traverse at least one layer to connect the top and bottom of the inductor.

MLC (multilayer ceramic) frequency selective circuit structures are disclosed. The MLC frequency selective circuit structures have a solenoid and toroid coil geometry in a multilayer electronic package which functions as a frequency selective tuned circuit in which both the number of turns and the aspect ratio of the solenoid coil are selected to adjust the tuned frequency. In some embodiments, a plurality of such coils can be connected together to provide a selected bandwidth about a tuned center frequency.

MLC frequency selective circuit structures

A process for the manufacture of a multilayer ceramic substrate includes fabricating the multilayer ceramic substrate from a monolith fabricated from universal layers and a monolith fabricated from custom layers. The universal layer monolith and the custom layer monolith are then joined to form the complete structure of the MLC substrate.

Dimpling of a workpiece by rebounding of a magnetic repulsion punch mechanism, when operated at high punching rates, is avoided by application of a damping pulse at a point at or subsequent to a mid-point of a return stroke of the punch from the workpiece and preferably within the last 10% of the return stroke. This damping pulse is preferably a fraction of the pulse width and of approximately the same amplitude as a driving pulse applying kinetic energy to the punch for causing punching of the workpiece. At high punching rates the kinetic energy of the return portion of a punching stroke is substantially determined by elastic rebounding of the punch from a guide bushing. The removal of kinetic energy during the return portion of the stroke allows the return of the punch to a position close to a rest position during a very short interval with small overshoot under control of mechanical damping. Since dynamic damping may be substituted for much of the mechanical damping in the punching arrangement, high quality punching may be accomplished at much increased punching rates. A preferred form of monitoring punch position employs RF reflected inductance and may be used to form a time expanded image of punch movement.

Magneto-repulsion punching with dynamic damping

A solid state lasing medium is pumped to produce a high repetition rate laser beam. The laser medium is pumped to cause maximum population inversion. The laser medium is greater in diameter than the aperture that defines the allowable beam path. In the preferred embodiment the off-axis laser beam that is produced is steered to become an on-axis laser beam using a novel SBSA (spinning beam steering assembly). The output of the laser is increased because as the SBSA spins, the area of the lasing medium that is not lasing is being charged or pumped. The laser medium can also be hollow to allow for pumping from either outside or inside the hollow bore or both. Similarly, this hollow bore in the laser medium could also allow cooling fluids to be circulated therethrough. Different embodiments of the SBSA are disclosed, including a variety of methods to pump the laser medium. Also, disclosed is a novel field removable or replaceable laser medium housing assembly.

A solid state lasing rod is spun on its long axis. The rod is pumped with photons while it spins. The rod is greater in diameter than the aperture. The rod is aligned off-center from the center of the aperture so that different portions of the rod are exposed to the aperture for lasing. The repetition rate of the lasing of the laser is increased because as the rod spins, the area of the rod that is not lasing is being charged. The laser rod can also be hollow to allow for pumping of the photons from either outside or inside the hollow bore or both. Similarly, this hollow bore in the laser rod could also allow cooling fluids to be circulated therethrough.
