摘要： In a power fastening tool for fastening a fastening member such as a screw or a fastening member, malfunction that driving of a motor is stopped before the fastening member is fastened completely can be prevented. A fastening judger judges that the fastening operation is completed when a value of an estimated torque T for fastening the fastening member becomes larger than a predetermined lower limit value T1 previously set by a user and a value of a torque variation ratio ΔΔT varies from positive to negative. Thus, it is possible to prevent malfunction for stopping driving of a motor even when the value of the torque variation ratio ΔΔT varies from positive to negative due to trouble before the vale of the estimated torque T becomes larger than the lower limit value T1.

摘要： In a power impact tool for fastening a screw or a bolt, malfunction that driving of a motor is stopped before the screw or the bolt is fastened completely can be prevented. A fastening judger judged that the fastening operation is completed at least when a torque variation ratio becomes substantially zero and a reference index becomes equal to or larger than a threshold value of trouble judgment. The reference index is a number of impact of a hammer in a term in which the torque variation ratios take positive values, and the threshold value of trouble judgment is calculated with using a maximum value of the torque variation ratio in the term. Since the number of the impact of the hammer due to trouble in fastening operation is smaller than that due to the screw or the bolt is fastened completely, it is possible to distinguish the increase of the torque in the former case from the increase of the torque in the latter case.
摘要翻译：在用于紧固螺钉或螺栓的动力冲击工具中，可以防止在螺钉或螺栓完全紧固之前停止驱动马达的故障。紧固判断器至少在转矩变化率变为基本为零且基准指数变为等于或大于故障判定的阈值时，判断紧固动作结束。基准指数是在扭矩变动率为正值的期间锤子的冲击次数，并且通过使用该项中的转矩变化率的最大值来计算故障判断的阈值。由于由于紧固操作的麻烦引起的锤的冲击次数小于由于螺钉或螺栓被完全固定的锤子的冲击次数，所以可以区分前一种情况下的扭矩的增加与扭矩的增加在后一种情况下。

摘要： In a hair dryer with a brush emitting minus ion to a hair in brushing, effect of the minus ion for hair treatment is increased. The hair dryer is comprised of a main body and a brush unit detachably engaged with an air outlet of the main body. A plurality of ion outlets is provided on a housing of the main body and disposed outside of the air outlet so that minus ion is emitted toward the brush unit. Since the minus ion emitted from the ion outlet is not shielded by the hair in brushing, the minus ion can be sprayed widely to the hair, and not directly heated by hot air flow blowing from the brush unit.

摘要： In an electrostatic atomizing hairdryer, electrostatically atomized mist generated in an electrostatic atomizing unit is effectively scattered into airflow emitted from a main body of the hairdryer so that the mist can be sprayed to hair uniformly and a time necessary for treatment of hair can be shortened. A tank constituting the electrostatic atomizing unit is detachably provided on a portion in the vicinity of an outer periphery of the main body, and an electrode unit for generating the mist is provided in a path of airflow sucked in an inside of the main body so as to be insulated from heat of a heating unit by an adiabator. A mist emitting opening from which the mist is emitted is disposed on a plane substantially the same as and at substantially the center of an air exit opening of the main body. Thereby, the mist emitted from the mist emitting opening is effectively scattered into the airflow emitted from the air exit opening.
