摘要： The present invention provides a compact, high-performance, and easy-to-manufacture taking optical system that offers an extremely high zoom ratio. The taking optical system includes, from the subject side, a first lens group having a positive optical power, a second lens group having a negative optical power, a third lens group having a positive optical power, and a fourth lens group having a positive optical power. The taking optical system achieves zooming by the movements of the first to fourth lens groups and focusing by the movement of the fourth lens group. The taking optical system fulfills the following conditions: 0.05≦f3/f4≦0.95 and 7.0≦f1/fw≦20.0, where f1, f3, and f4 represent the focal lengths of the first, third, and fourth lens groups, respectively, and fw represents the focal length of the entire taking optical system at the wide-angle end thereof.

摘要： To definitely remove stains in a small and narrow clearance. Thread 2 is spirally wound around a wire 1 formed by material with plasticity, the two or more thread-wound wires obtained are twisted together in spirals to bring the thread 2 in close contact with the wire 1 and the overall diameter is held to be small. In addition, with the winding thread, spiral narrow-width protrusions and recesses are formed, with the thread-wound wire, spiral wide-width protrusions and recesses are formed, and by crossing these and allowing a large number of small and large protrusions and recesses to be mixed, chances to catch removed matters are increased, and a satisfactory scratching condition is achieved.

摘要： An imging lens device has a zoom lens system and an imaging sensor. The zoom lens system has a plurality of lens units and changes gaps between the lens units to thereby generate an optical image of an object which can be optically and successively zoomed in and out. The imaging sensor which converts an optical image generated by the zoom lens system into an electric signal. The zoom lens system comprises, from the object side, a first unit having a negative power, a second unit having a positive power, the second unit having a cemented lens element joining three lens elements, and a lens element having a positive power, a third unit having a positive power, and an aperture stop disposed between the first unit and the second unit. Among the three lens elements which form the cemented lens element, a lens element disposed on the object side directs a convex surface toward the object side while a lens elements disposed on the image side directs a concave surface toward the image side.
