摘要： A magneto generator for an engine having a flywheel, in which the flywheel comprises a rotor mounted for axial rotation and has a rim of magnetically permeable material. A magnetically permeable core has first and second ends located adjacent to the rim at circumferentially spaced points. At least two wire coils are wrapped on the core. The rim defines a permeability path between the ends of the core. A fixed magnet is placed on one end of the core. The rim is interrupted at circumferentially spaced points to provide walls and windows alternately making and breaking the permeability path when the rotor is rotated to produce voltage pulses in sinusoidal form in the coils. The positive half cycles in one of the coils is used to charge an ignition storage capacitor for energizing a spark plug. The negative half cycles in the other winding are used to charge a battery.

摘要： A circuit board unit includes a substrate with imprinted circuit traces and components. A plurality of traces include connecting areas for connection to another trace area or to an external lead. An interconnect element is soldered to each area. Each element is an integral flat strip-like member bent into a substantial L-shape configuration. The element has a flat, square base plate with a control hole centrally located therein. A terminal leg is interconnected to the base plate by a smoothly curved portion and extends at right angles to the base plate and is aligned with the center of the hole. The outer end is a flat terminal having a pin-like projection. A solder paste on the trace has a configuration conforming to the base plate. The base plate is placed on the solder with a slight pressure. Upon melting of the solder, the hole essentially prevents floating of the element while the conformed plate and paste area align the plate on the solder area as a result of surface tension and wetting effect. The interconnect elements are formed as a series of stamped flat blanks, connected on one edge by a strap having indexing openings for automated movement from a reel supply. The blanks are advanced into a pneumatic forming machine, where it is formed and removed from the strap. A placement head grasps the terminal end of the formed element and places it onto the solder pad. The substrate moves through a reflow soldering unit to solder the interconnect element to the substrate trace. The substrate is placed in a housing with the element abutting an exterior terminal for automated pinch welding.
