Title: Zoom lens
Inventor: KANZAWA AKIOKI
IPC: G02B7/10
Filed: 1988-04-30
Abstract: PURPOSE:To obtain invariably proper image magnification by relating the driving mechanisms of the lens group of the foremost array and a variator system lens group to each other so that the product of the extension quantity of the lens group of the foremost array and the overall focal length of the lens system is constant. CONSTITUTION:The driving mechanism of the focusing system lens group 1 is related to the driving mechanism of the variator system lens group 2 for converting the focal length of the whole lens system so that the product of the extension quantity of the focusing system lens group 1 from an infinite distance position and the focal length of the whole lens system is constant. Namely, when the extension quantity of the focusing system lens group 1 from the infinite distance position is large and the image magnification increases, the variator system lens group 2 is so driven that the focal length of the whole lens system becomes short. When the extension quantity is small and the image magnification decreases, on the other hand, the variator lens 2 is so driven that the focal length of the whole lens system becomes long. Consequently, the image magnification can be made invariably constant.

IPC: C02F1/50
Filed: 1997-04-25
Abstract: PROBLEM TO BE SOLVED: To control effectively the generation of algae at low cost by using an agent adding means attached, combinedly to a water reservoir for water stored in the water reservoir, circulating the stored water by a water circulating means and operating intermittently the water circulating means for a short time by a control means. SOLUTION: Copper sulfate of given amount is added into a pool 2 by an agent adding means 4, and then a water circulating means 3 is operated based on a set operation pattern by a control means 4. When the given operation pattern is set, stored water W is circulated for a short time by the proper circulating operation of a circulating pump 7 and then the stored water remains for a long time. Thus the copper ion concentration gradient in the stored water W becomes small by the circulation for a short time and the remaining for a long time, and copper ions are in existence uniformly around spores of algae, by which the selective ingestion of nutritive elements and copper ions by the spores is impossible and the simultaneous ingestion of both is performed to generate the cell destruction of spores of algae and control the generation and proliferation of algae.
