摘要： A connector for a printed circuit board has a printed circuit board having a cut-out portion at one corner of its inserting end side and a plurality of contact points or conductor strips juxtaposed along a marginal portion of its inserting end and a connector body having a groove through which the printed circuit board is inserted and withdrawn. The groove is provided therein with a plurality of contacts which are arranged in such a manner as to be resiliently contacted with a group of the contact points. The connector body is provided with a single push-up lever for pushing up one side of the printed circuit board. The single push-up lever is pivotally supported on one end portion of the connector body. The push-up lever is provided with a push-up portion adapted to engage with the cut-out portion of the printed circuit board. The cut-out portion is given a push-up force by the push-up portion resulting from pivotal movement of the push-up lever. The printed circuit board is pushed up at one end side thereof in a cantilever fashion when it is withdrawn.

摘要： A single spot fuel injector is energized only twice per revolution of the crankshaft of the engine so that under given operating conditions the injections coincide with the TDC and BDC positions of a piston of a selected cylinder of the engine. Under higher engine speed operation, the injection timing is advanced to improve the fuel distribution to the cylinders. When the engine operates at an engine speed below a predetermined level it is possible for the injector to be energized three times per revolution of the crankshaft.

摘要： A carburetor is disclosed of the variable venturi type, which has a bypass passage bypassing the throttle valve, which is controlled during starting and warming up of the engine by a piston which adjusts its flow resistance, and which is urged against the biasing action of a spring by the vacuum suction downstream of the throttle valve. The maximum open position of this piston is controlled by a heat-sensitive element which advances this position in the direction of closing the bypass passage as the engine warms up, until it is completely closed when the engine is warm. Air is fed into a supplier which supplies fuel to the carburetor inlet passage to mix with the fuel supplied thereby in an amount which varies from a minimum when the vacuum downstream of the throttle valve is minimum to a maximum when the vacuum downstream of the throttle valve is maximum. Further, the amount of fuel supplied by the fuel supplier is adjusted to be greater when the engine temperature is lower than when it is higher. Thereby choking action is provided for a cold engine, and also a function of providing an enriched mixture upon acceleration during warming up is provided.
