摘要:
The present invention provides a rare metal/platinum-group metal extractant, which has a completely new structure compared with the conventional rare metal/platinum-group metal extractant and which exhibits excellent extraction performance; it also provides a method for extracting rare metals and platinum-group metals using the extractant. The rare metal/platinum-group metal extractants of the present invention is the one to extract rare metals and platinum-group metals by contacting a solution, in which several kinds of rare metals and platinum-group metals are dissolved, with a solution in which a cyclic phenol sulfide of the following Formula (1) is dissolved to make the rare metals and platinum-group metals move into the cyclic phenol sulfide solution.

Object is to provide an inner-focusing type zoom lens system carrying out focusing by moving a portion of a first lens group suitable for an auto-focus SLR camera. A zoom lens system includes, in order from an object, a first lens group having positive refractive power, a second lens group having negative refractive power, and a third lens group having positive refractive power. Upon zooming from a wide-angle end state to a telephoto end state, a distance between the first and the second lens groups increases, and a distance between the second and the third lens groups decreases. The first lens group is composed of, in order from the object, a 1A lens group G1A having positive refractive power, and a 1B lens group G1B having positive refractive power. Focusing from infinity to a close-range object is carried out by moving only the 1B lens group G1B to the object.

Providing a zoom lens system that satisfies making the focusing lens light and reducing a moving amount for focusing, simultaneously. The zoom lens system includes a first lens group having positive power, a second lens group having negative power and a third lens group having positive power. When zooming from a wide-angle end state to a telephoto end state, at least the first and third lens groups are moved such that a distance between the first and second lens groups increases, and a distance between the second and third lens groups decreases. The first lens group is composed of a front lens group with positive power having at least one negative lens and at least one positive lens, and a rear lens group with positive power having one positive lens. Focusing from infinity to a close object is carried out by moving only the rear lens group to the object.

The present invention provides a compact zoom lens system suitable for a video camera and a digital still camera using a solid-state imaging device, having a zoom ratio of 3.5 or more, an angle of view in a wide-angle end state of about 60°, and superb optical performance. According to one aspect, in order from an object side, a first lens group has negative refractive power, a second lens group has positive refractive power, and a third lens group has positive refractive power. The front principal point of the second lens group is located to the object side of the most object side surface of the second lens group. The distance between the first and second lens group is decreased and the distance between the second and third lens group is increased upon zooming from a wide-angle end state to a telephoto end state. Predetermined conditional expressions are satisfied.
