    • PROBLEM TO BE SOLVED: To provide a portable drilling machine capable of enhancing the operability and safety by preventing occurrence of any overload state again after occurrence of overload. SOLUTION: An AC power supply 10 is connected with a motor 12 for rotating a drill through a motor control section 28, a current detecting section 30 and a power switch 36, and connected with a magnet 16 through the power switch 36 and a full-wave rectifier 18. The motor control section 28 rotary-drives the motor according to a signal from a main control section based on the fact that a motor start switch 38 is turned on. The main control section 14 controls a voltage supplied to the motor 12 to lower gradually when the motor 12 enters overload state, and to raise the voltage gradually when overload state is eliminated thus performing normal power supply. Furthermore, the main control section 14 controls the motor control section 28 to stop power supply to the motor 12 when overload state sustains for a predetermined time. COPYRIGHT: (C)2007,JPO&INPIT
    • 要解决的问题:提供一种能够通过在发生过载之后再次防止发生任何过载状态而提高操作性和安全性的便携式钻孔机。

      解决方案:交流电源10与马达12连接,用于通过电机控制部分28,电流检测部分30和电源开关36旋转钻头,并通过电源开关36与磁铁16连接, 全波整流器18.电动机控制部28基于电动机起动开关38接通的事实,根据来自主控制部的信号旋转驱动电动机。 主控制部分14控制当马达12进入过载状态时供给马达12的电压逐渐降低,并且在过载状态被消除时逐渐升高电压,从而进行正常供电。 此外,当过载状态保持预定时间时,主控制部14控制电动机控制部28停止对电动机12的供电。 版权所有(C)2007,JPO&INPIT

    • PROBLEM TO BE SOLVED: To provide an articulated robot capable of controlling its joints so as to continue working as long as possible while moderating an overload state when a load working on the joints is excessive.
      SOLUTION: The load working on each of the joints is estimated by a load estimation part 32, and the overload joint the estimated load of which is larger than a threshold value is specified by an overload specification part 34. An order of precedence previously set against a target value vector of a head end link of the robot and elements of the vector is memorized in a memory device 40. A target value element extraction part 42 extracts elements of the same number as non-overload joints from the target value vector in order of the order of precedence in height. Target driving quantity to drive the joints in the same direction as the load is decided against the overload joints by a force control computation part 36. The target driving quantity to realize the extracted target value elements is decided against the non-overload joints by an inverse conversion part. It is possible to control the non-overload joints so as to follow the target vector as much as possible while controlling the overload joints in the direction to moderate the load.
