    • A zoom image-forming optical system used in combination with an infinity-correction objective lens, the zoom image-forming optical system including: a tube lens for condensing a luminous flux from the objective lens to form an intermediate image; and a relay lens with a zoom function for projecting the intermediate image onto an image plane. The relay lens includes a first lens group with positive power, a second lens group that belongs to a movable group with positive power, a third lens group that belongs to a movable group with positive or negative power, and a fourth lens group with negative power, in this order from the intermediate image side. The zoom image-forming optical system changes its magnifying power by moving the second lens group and the third lens group in an optical axis direction.
    • 一种与无限远校正物镜组合使用的变焦图像形成光学系统,所述变焦图像形成光学系统包括:用于会聚来自所述物镜的光通量以形成中间图像的管透镜; 以及具有用于将中间图像投影到图像平面上的变焦功能的中继透镜。 中继透镜包括具有正功率的第一透镜组,属于具有正光焦度的可移动组的第二透镜组,属于具有正或负电源的可移动组的第三透镜组,以及负功率的第四透镜组 ,从中间图像侧按此顺序。 缩放图像形成光学系统通过沿着光轴方向移动第二透镜组和第三透镜组来改变其放大倍率。

    • In a communication network system with a plurality of nodes connected to a common transmission line, each master candidate node includes an idle time measurement device for measuring an idle time of the transmission line. Once each master candidate node acquires the master privilege and becomes a master node, the master node retains a master privilege until the idle time of the transmission line exceeds a longest of the privilege acquisition idle time widths of the master candidate nodes, the root node transmits a start frame indicating start of a next communicant cycle and the idle time measurement device is cleared upon receipt of the start frame.
    • 在具有连接到公共传输线的多个节点的通信网络系统中,每个主候选节点包括用于测量传输线的空闲时间的空闲时间测量装置。 一旦每个主候选节点获取主机特权并成为主节点,则主节点保留主机特权,直到传输线的空闲时间超过主候选节点的特权获取空闲时间宽度的最长时间,根节点发送 指示开始下一个通信周期的开始帧,并且在接收到开始帧时清除空闲时间测量设备。
