    • The velocity of a working tool of a hydraulic excavator can be automatically decelerated and stopped just before the working tool would encounter an obstacle. Hazard regions and decelerating regions which correspond upward, downward, forward, and other positions of the hydraulic excavator are designated and a working tool decelerating pattern V.sub.2 where the working tool velocity decreases from 100% to 0% in a decelerating region is stored in a control unit. When a working tool velocity V.sub.1 which corresponds to the amount of operations of working tool levers (1, 2) intersects with the working tool decelerating pattern V.sub.2 in a decelerating region, the working tool moves at the velocity V.sub.2 and stops just before a hazard region. A restoring pattern where the working tool is restored from a just-before-hazard position to a safety region is stored as a working tool accelerating pattern V.sub.4 where the working tool velocity accelerates from a predetermined velocity just before a hazard region. This working tool accelerating pattern V.sub.4 is stored in the control unit. The working unit velocity is accelerated along the working tool accelerating patter V.sub.4. After the working tool accelerating pattern V.sub.4 intersects with a working tool velocity V.sub.3, which corresponds to the amount of operations of the working tool levers (1, 2), the working tool moves at the velocity V.sub.3.
    • 液压挖掘机的作业工具的速度可以在工作工具遇到障碍物之前自动减速停止。 指定对应于液压挖掘机的向上,向下,向前和其他位置的危险区域和减速区域,并且在减速区域中将作业工具速度从100%降低到0%的作业工具减速模式V2被存储在控制器 单元。 当对应于作业工具杆(1,2)的操作量的作业工具速度V1与减速区域中的作业工具减速模式V2相交时,作业工具以速度V2移动,并且在危险区域之前停止 。 将作业工具从刚好从危险位置恢复到安全区域的恢复模式被存储为作业工具加速模式V4,其中工作工具速度在危险区域之前从预定速度加速。 该工作加速模式V4存储在控制单元中。 工作单元速度沿工作加速模式V4加速。 在加工刀具加速图案V4与与作业工具杆(1,2)的操作量对应的加工刀具速度V3相交后,加工刀具以速度V3移动。

    • An optical connector has: a holding member having an accommodating portion formed at an end thereof for accommodating a collimator lens and an insertion hole formed at an opposite end thereof for inserting an optical fiber; and a resin joint having a first insertion hole formed at an end thereof for inserting the holding member and a second insertion hole formed at an opposite end thereof for inserting the optical fiber. The collimator lens and the optical fiber are positioned by making at least one of the collimator lens and an end surface of the optical fiber abut against a recess formed in the holding member near the accommodating portion. The resin joint has a fixing portion formed therein for fixing a part of the optical fiber positioned in the holding member inserted via the first insertion hole into the resin joint, the part being exposed from the holding member.
