摘要： Disclosed is a variable venturi type carburetor comprising a movable suction piston which changes the cross-sectional area of a venturi portion of an intake passage in response to the amount of air flowing therethrough. The suction piston has a needle entering into a stationary jet. The needle and the jet define an annular opening through which the fuel is injected into the venturi portion. The jet is connected to a fuel reservoir via a fuel supply passage. On the bottom face of the suction piston and on the inner wall of the venturi portion, members for magnetically attracting each other are mounted, respectively.

摘要： Disclosed is a variable venturi type carburetor comprising a movable suction piston. The suction piston has a needle entering into a stationary jet. The needle and the jet defines an annular opening through which the fuel is injected into the intake passage formed in the carburetor. The fuel recirculating pump is connected to the fuel tank via the fuel recirculating passage. A restricted opening is formed in the fuel recirculating passage for forming a vacuum zone in the fuel recirculating passage located between the fuel recirculating pump and the restricted opening. The vacuum zone is connected to the jet.

摘要： A focusing device for providing an indication of the in-focus condition of a lens relative to a scene and a focal plane, F.sub.0. An a.c. bridge circuit includes photoelectric elements in two legs thereof; the elements being physically positioned just in front and just behind, respectively, of focal planes F.sub.1, F.sub.2 which are optically at the same distance from the lens as focal plane F.sub.0. An a.c. input voltage is applied to the bridge, and the output therefrom is an a.c. voltage which has a phase and an amplitude dependent upon the differential amount of light impinging on the first and second photoelectric elements. As the focal plane of the lens moves from a plane in front of F.sub.0 to a plane behind F.sub.0, the a.c. amplitude goes from maximum at phase 0.degree. to minimum at phase 180.degree., passing through zero amplitude when the lens is positioned to cause the light from the scene to be focused exactly at F.sub.0.
