    • A key switch which could, for example, be used to switch a power supply for a machine tool on and off, has a locking mechanism on a rotating element of a key disengages the locking mechanism on the rotating element. The key also engages the guide on the rotating element, thereby initiating the rotation of that element and activating the switching element. If an object other than the key is inserted, the lock on the rotating element will not be released, and the rotating element will be prevented from moving, so that the switching element cannot be activated. Furthermore in another embodiment, a machine stop detection signal is fed to an internal solenoid which prevents removal of the key until the machine stops completely.
    • 可以例如用于切换机床的电源的钥匙开关在钥匙的旋转元件上具有锁定机构,从而使旋转元件上的锁定机构脱离。 钥匙还与旋转元件上的引导件接合,从而启动该元件的旋转并激活开关元件。 如果插入了钥匙以外的物体,旋转元件上的锁定将不会被释放,并且旋转元件将被阻止移动,从而不能激活开关元件。 此外,在另一个实施例中,机器停止检测信号被馈送到内部螺线管,其防止钥匙的移除,直到机器完全停止。

    • A zoom lens including first to fifth lens units in order from an object side toward an image. The refractive powers of the first to the fifth lens units are positive, negative, positive, negative and positive, respectively. The distance between the first and the second lens units is increased at the time of zooming from the wide angle end to the telephoto end, and the distance between the second and the third lens unit is decreased at the time of zooming from the wide angle end to the telephoto end. The first lens unit and the fourth lens unit are fixed for the zooming. When M2 and M3 are the amounts of movement of the second lens unit and the third lens unit at the time of zooming from the wide angle end to the telephoto end, respectively, the conditional expression; 0.2
    • 一种变焦透镜,包括从物体侧朝向图像的顺序的第一至第五透镜单元。 第一至第五透镜单元的折射力分别为正,负,正,负和正。 第一透镜单元和第二透镜单元之间的距离在从广角端到望远端的变焦时增加,并且在从广角端变焦时第二和第三透镜单元之间的距离减小 到远摄端。 第一透镜单元和第四透镜单元被固定用于变焦。 当M2和M3分别是从广角端到望远端的变焦时的第二透镜单元和第三透镜单元的移动量时,条件表达式; 0.2 <| M2 / M3 | <5.0。
