    摘要: A zoom lens system in accordance with this invention is composed of a first fixed lens group, a first movable lens group, a second movable lens group and a second fixed lens group arranged in this order from front to rear, wherein a stop is are located at the center of the whole lens system and the first fixed lens group and the second fixed lens group consist of the same lens elements and located symmetrically with respect to the stop, and similarly the first movable lens group and the second movable lens group consist of the same lens elements and are located symmetrically with respect to the stop. The first movable lens and the second movable lens are asymmetrically moved with respect to the stop in accordance with the location of the whole lens system that is changed to vary the magnification, whereby the distortion and the focus shift caused by the field curvature fluctuation are eliminated throughout the variable range of magnification. Further, the zoom lens system in accordance with this invention is characterized in that the power of the lens groups and the lens elements is designed to make the whole lens system compact in size.

    摘要: An internal combustion engine of the in-line type having a surge tank located above the engine. Intake tubes connect the surge tank with the in-line engine cylinders. The tubes extend from one side of the engine body in a direction away from the engine body and are then curved upwardly in a U-shaped manner toward the surge tank. Surge tank openings and the ends of the intake tubes connected together are both formed as ellipses having a major axis lying in a direction parallel to the cylinder axes. The cross-sectional shape of the intake tubes gradually changes from an ellipse into a circle at approximately the middle or bend of the intake tube.
