    Abstract: A spark-ignition gasoline engine having at least a spark plug, the engine including an engine body having a geometrical compression ratio set at 14 or more, and an intake valve and an exhaust valve provided, respectively, in intake and exhaust ports connected to each of a plurality of cylinders of the engine body. The intake and exhaust valves are adapted to open and close corresponding respective ones of the intake and exhaust ports. The engine further includes an operation-state detector adapted to detect an operation state of the engine body and a control system adapted, based on detection of the operation-state detector, to perform at least an adjustment control of an ignition timing of the spark plug, the control system being operable, when an engine operation zone is a high-load operation zone including a wide open throttle region within at least a low speed range, to retard the ignition timing to a point within a predetermined stroke range just after a top dead center of a compression stroke.

    Abstract: A zoom lens system which includes a first lens group, a second lens group, and a third lens group, sequentially arranged from an object side of the zoom lens system to an image side thereof, and an aperture stop which is arranged between the first lens group and the second lens group. The first lens group and the second lens group have a positive focal length. The third lens group has a negative focal length. The second lens group is used for focusing. When the zoom lens system performs a zooming operation, the first lens group, the second lens group, the third lens group, and the aperture stop are moved along an optical axis toward the object side of the zoom lens system, such that a distance between the first lens group and the aperture stop, and a distance between the aperture stop and the second lens group increase, while a distance between the second lens group and the third lens group decreases.

    Abstract: A zoom finder has first to third lens groups sequentially arranged from an object side to an eye pupil side and performs a zooming operation by fixing the first and third lens groups and moving the second lens group. The first lens group is constructed by a positive single lens. The second lens group is constructed by a negative single lens. The third lens group has a positive combinational focal length and is constructed by a negative single lens arranged on the object side and a positive single lens arranged on the eye pupil side. A frame system of the zoom finder is formed by an eye pupil side lens face of the negative single lens of the third lens group and the positive single lens of the third lens group. Radii R.sub.1 and R.sub.2 of curvature of lens faces of the first lens group on the object and eye pupil sides satisfy the following condition.0.8
