Title: Superwide-angle zoom lens
Inventor: SATO HARUO
IPC: G02B15/20
Filed: 1997-05-23
Abstract: PROBLEM TO BE SOLVED: To obtain a high-performance superwide-angle zoom lens including a super wide angle and having a large aperture ratio and a comparatively high variable power ratio by providing a negative lens group and a positive lens group in order from an object side and satisfying a specified condition. SOLUTION: This zoom lens is equipped with the negative 1st lens group G1 and the positive 2nd lens group G2 in order from the object side and varies power by changing an air spacing between both lens groups G1 and G2. The 1st lens group G1 has a negative meniscus aspherical lens L11 whose convex surface faces to the object side and whose surfaces on the object side and an image side are formed to be aspherical.  Then, it is assumed that the maximum effective radius of the aspherical surface on the object side of the lens L11 is (ha) and distances along an optical axis between respective points on the aspherical surface on the object side at the position of the maximum effective radius (ha) and at the position of the 1/2 value of the maximum effective radius (ha) and the tangential plane of the apex of the aspherical surface on the object side are ΔSa and ΔSa', respectively. In this case, the condition 0.05<(ΔSa/ ha)-(2.ΔSa'/ha)<1 is satisfied.

Title: Method for treating and refining of molten steel before continuous casting
Inventor: ISHII TOSHIO
IPC: B22D11/116
Filed: 1989-06-15
Abstract: PURPOSE:To prevent the generation of a dead zone and to eliminate the danger of contamination by forming the wall surface plane in one angle part of a tundish to a bow shape and hanging an immersion pipe to suck up a molten steel at the time of charging the molten steel dissolved therein with a soluble gas in the tundish into a vacuum chamber. CONSTITUTION:The molten steel 2 subjected to converter refining is continuously charged into the tundish 1 via a ladle and gaseous N2 is blown from a gas bubbling nozzle and is dissolved into the molten steel 2. This molten steel 2 is sucked up by the immersion pipe 3a and is charged into the vacuum chamber 3 in a reduced pressure state, by which the molten steel is degassed and the inclusions are removed by the generation and floating of the fine bubbles of the gaseous N2. The molten steel is poured from a sliding nozzle 4 into the mold. The plane shape in the one angle part of the tundish 1 is formed to the bow and parabolic shape and the immersion pipe 3a provided in the lower part of the vacuum chamber 3 is hung to this angle part to suck up the molten steel 2. The generation of the dead zone in the tundish 1 by the stagnation of the molten steel 2 therein is prevented in this way and the contamination of the molten steel 2 by contaminants, etc., is obviated.

Title: Real image type zoom finder
Inventor: YAMAGUCHI TAKAO
IPC: G02B13/18
Filed: 1989-06-14
Abstract: PURPOSE:To prevent the vignetting of the luminous flux of a finder and to faithfully catch the change of the viewing angle of a photographing lens system by means of the finder by arranging the group of an objective lens system on a side closest to an object and the group of a photographing lens system on the side closest to the object on an optical axis nearly without being positioned back and forth and providing the ratio of paraxial variable power obtained by considering the amount of distortion aberration. CONSTITUTION:The objective lens system is constituted of two groups 1 and 2. In the case of performing zooming movement to a long focal distance side, the 1st group 1 and the 2nd group 2 move to the object side while narrowing the space between them each other and the 1st group 1 and the group 8 of the photographing lens system on the side closest to the object move nearly in parallel on parallel optical axes AX and AXF. The ratio of paraxial variable power KP of the objective lens and the ratio of variable power KT of the photographing lens system are set to satisfy the relation of KP<KT. Namely, since the 1st group 1 and the group 8 of the photographing lens system are hardly positioned back and forth, the luminous flux of the finder is not vignetted. Then, the ratio of the paraxial variable power obtained by considering the amount of the distortion aberration is provided, so that the change of the viewing angle of the photographing lens can be faithfully observed. Thus, the vignetting of the luminous flux of the finder is prevented and the change of the magnification of the photographing lens system is excellently followed.
