    摘要： The present device relates to a chair in which a base member is fitted onto an upper portion of a leg comprising a plurality of castors in contact with a floor together with support members for these castors, and a seat portion and a back rest are provided on an upper portion of a support plate that is capable of reclining with respect to the base member. This chair is also provided with a cam-shaped link capable of rotating about the periphery of a pin provided in the base member, an upper portion of the link protrudes towards the support plate side, and a corresponding elastic member that is compressed by the rotation of the link is provided in a bottom portion of the base member. A shaft portion in contact with the link, and which causes the link to change profile in response to the reclining action, is provided within the support plate. This configuration provides a chair that is inexpensive and can naturally adopt either a serious working position or a relaxed reclining position.

    摘要： A numerical control device for controlling rotation of a servomotor in response to numerical control data to move a movable member by a commanded feed amount at a commanded feed rate. A velocity detector detects an actual feed rate of the movable member. A register stores an allowable feed rate data. A comparator compares an allowable feed rate data from the register and an actual feed rate from the velocity detector to output an abnormal signal when the actual feed rate exceeds the allowable feed rate. The allowable feed rate data is set into the register each time the commanded feed rate is changed.

    摘要： A contact detecting apparatus for detecting the contact of a workpiece with a tool in a machine tool which comprises a coil mounted on the periphery of a spindle head and connected to an AC power source for generating an induced current in a looped secondary circuit including the workpiece, a work table, a machine body, a spindle head, a tool spindle and the tool, when the workpiece and the tool are moved relatively into contact with each other. Bypassing elements are included in the secondary circuit for bypassing an electric resistance in spindle bearings. A detector is connected between the AC power source and the coil for detecting a change in an electric signal caused by the contact between the workpiece and the tool.

    摘要： A tool position offsetting system for a spare tool, including a tool life detecting device provided for detecting a broken or substantially worn tool and for replacing the same by a spare tool, and a detecting device which detects whether the spare tool is inserted in the tool spindle. If the detecting device makes a detection, an input controlling circuit applies several signals to a numerical controller so as to instruct the same to introduce the dimensional data for the spare tool into the memory of the numerical controller, resulting in amending the offset data stored in the memory before a machining operation. After the machining operation, the input controlling circuit applies several signals so as to remove the dimensional data from the memory, resulting in restoring the tool offset data to its original setting.
