    • Scanning switch means 21 to 2m can connect scanning lines S1 to Sm freely to a first potential or a second potential. Drive switch means 71 to 7n can connect drive lines D1 to Dn freely to a drive current source 70 or an off potential. Control means 8 connects the scanning switch means 21 to 2m sequentially with the first potential to select the scanning lines S1 to Sm sequentially and to control the connected states of the drive switch means 71 to 7n. In accordance with the number of the drive lines D1 to Dn to be connected to the drive current source 70, the control means 8 changes the resistances of the scanning switch means 21 to 2m corresponding to the scanning lines S1 to Sm connected to the second potential to become the unselected state, into at least two stages.
    • 扫描开关装置21至2m可以将扫描线S1至Sm自由地连接到第一电位或第二电位。 驱动开关装置71至7n可以将驱动线D1至Dn自由地连接到驱动电流源70或关闭电位。 控制装置8依次将扫描开关装置21与2m依次连接,以顺序地选择扫描线S1至Sm,并控制驱动开关装置71至7n的连接状态。 根据要连接到驱动电流源70的驱动线D1至Dn的数量,控制装置8将扫描开关装置21的电阻改变为与连接到第二电位的扫描线S1至Sm相对应的2m 成为未选择的国家,进入至少两个阶段。

    • In an impact type clamping apparatus including a motor unit for generating a pulsatory driving torque, a main spindle driven by said pulsatory driving torque to rotate a fastening member, a detecting unit for detecting a pulsatory torque applied to the main spindle, a calculating circuit for calculating a clamping force in accordance with a peak value of the pulsatory torque, and a control unit for stopping the operation of said motor unit when the calculated clamping force exceeds a desired clamping force, said clamping force is calculated not only from the peak value of the pulsatory torque but also from an increasing coefficient which represents a relationship between the peak value of the pulsatory torque and an increment of the clamping force. The increasing coefficient is gradually decreased in accordance with the increase in the clamping force, so that the clamping force can be calculated very accurately and the fastening member can be clamped with an actual clamping force which is very close to the desired clamping force.
