Abstract: A process for making electronic filter circuit components is provided which comprises forming a flat electrically conductive layer on a wafer formed of ceramic, or of other appropriate dielectric material, the conductor being shaped to provide a portion of an inductive coil, or a capacitive element. The process of the invention assures relatively low resistance in the conductive layers so as to provide a filter circuit of a relatively high quality factor (Q), when a plurality of such wafers are stacked and appropriately interconnected.

Abstract: An integrated electrical component is provided which functions as an inductive-capacitive network, and which may be used, for example, to form a filter, transformer, or the like. The component includes distributed capacitance and inductance with external connections to permit a variety of distributed element configurations, which results in the elimination of spurious electromagnetic radiation from the component and in the packaging of a multiple-pole filter in an extremely compact configuration, so as to provide a variety of filter networks, or the like, each of high quality factor (Q). The component comprises one or more sheets of dielectric material formed, for example, of a ceramic, and having one or more conductive sheets positioned on each dielectric sheet. The resulting assembly is turned into a spiral configuration, as will be described, to form the component, and the resulting assembly is then cured.

Abstract: This invention concerns an electronic controlled manifold injection system for internal combustion engines which provides a completely symmetrical flow of the air/fuel mixture to both ends of the engine, vaporizes the fuel by the application of heat to provide identical air/fuel charges to all cylinders of the engine, and by utilizing mass flow sensors in both the flow of air into the engine and the flow of fuel from the injection pump, provides a solid state control of the injection pump delivery to maintain a constant or programmed air/fuel ratio for all accelerating, decelerating and steady state operation of the engine.
