Abstract: A control system including a microprocessor for controlling the controlled variables of an internal combustion engine, especially, the flow rate of fuel is disclosed. An air flow meter provides an output signal having such a non-linear characteristic relative to the flow rate of intake air that the signal level increases in the region of the small flow rate of intake air. The microprocessor carries out necessary digital computation on the basis of the output signal of the air flow meter to provide a fuel flow rate control signal. This digital control signal is converted into a signal having a linear characteristic proportional to the flow rate of intake air, or after having been produced from the microprocessor, converted into a signal including information proportional to the flow rate of intake air.

Abstract: A gold jewelry clasp assembly is described, which includes a keeper for receiving a catch and retainer, wherein all of the elements are constructed to operate reliably over a long life time. The catch is formed of a tempered gold strip bent at its middle to form a folded leaf spring, and with one end of the strip bent into a loop around a pivoting wire retainer.

Abstract: A slide fastener chain is fed along a chain path by a feedout mechanism until a leading end of the chain gripped by the feedout mechanism reaches a first feeder mechanism past a cutting mechanism. The first feeder mechanism is then actuated to feed the chain toward a second feeder mechanism. The first feeder mechanism is then inactivated and the second feeder mechanism is actuated to feed the chain at a higher speed. A slider on the chain is engaged by a slider sensor to intermesh element rows on the chain as it is transported by the second feeder mechanism.

Abstract: The invention pertains to a ball joint assembly which includes a ball stud received in a swivel socket of a supporting body. Some of such assemblies are classed as quick disconnects, meaning that the ball stud may be conveniently assembled and disassembled as desired. In another class, the bodies are substantially cylindrical with the sockets forming a pair of diametrically opposed feather edges. In drilling the sockets, it is not uncommon for a burr to be formed about the perimeter, and for this burr to be bent inwardly thereby obstructing the free insertion of the ball stud into the socket. Also it is not uncommon for the feather edges to be bent inwardly resulting in the same problem. By counterboring the socket, the burr is removed and the feather edges are flattened which not only solves the obstruction problem but may also provide other advantages.
