    • In a zoom lens having a variable power ratio representing a ratio of a focal length at a telephoto end position to a focal length at a wide angle end position being not less than 2.5 times, the zoom lens includes, in the order named from an object side: a first lens group having a negative focal length; a second lens group having an aperture-stop and a positive focal length; and a third lens group having a positive focal length. When a magnification is varied from the wide angle end position to the telephoto end position, all of the first, second and third lens groups are moved in an optical axis direction of the zoom lens so that a distance between the first and second lens groups is decreased. The first lens group Includes, in the order named from the object side, a first positive lens whose convex surface faces the object side, a second negative meniscus lens whose convex surface faces the object side, a third negative lens, and a fourth positive lens.
    • 在具有表示长焦端位置处的焦距与广角端位置的焦距的比例的可变功率比的变焦镜头不小于2.5倍时,变焦镜头按照从物体 侧:具有负焦距的第一透镜组; 具有孔径光阑和正焦距的第二透镜组; 以及具有正焦距的第三透镜组。 当放大倍数从广角端位置变化到望远端位置时,所有第一,第二和第三透镜组都沿变焦透镜的光轴方向移动,使得第一和第二透镜组之间的距离为 减少。 第一透镜组以物体侧的顺序包括凸面朝向物体侧的第一正透镜,凸面朝向物侧的第二负弯月形透镜,第三负透镜和第四正透镜 。

    • A device for emergently relieving pressure comprises a flexible plate bent downward and having its periphery attached to the inner surface of a hatch coaming, wherein the periphery of the plate is welded to the inner surface of the coaming at appropriate intervals, and the gap between the remaining part of the periphery of the plate and the coaming inner surface is sealed by a sealant.When a specified pressure exerts on the flexible plate, the plate starts bending back upward. With the upward bending of the plate, the welds between the plate and the coaming are deformed and broken, allowing the plate to be blown off from the coaming. Thus the device, if installed on a fuel tank, serves to relieve the pressure in the tank for the maintenance of safety.
    • 用于紧急释放压力的装置包括向下弯曲并且其周边附接到舱口围板的内表面的柔性板,其中板的周边以合适的间隔焊接在铰链的内表面上,并且间隙 板的周边的剩余部分和环形内表面被密封剂密封。 当指定的压力施加在柔性板上时,板开始向上弯曲。 随着板的向上弯曲,板和铰链之间的焊缝变形和断裂,允许板从结构体中吹脱。 因此,如果装置安装在燃料箱上,则能够缓解油箱中的压力以维持安全。
