摘要： PROBLEM TO BE SOLVED: To enhance the workability by moderating variation in the r.p.m. of a motor when a work is started using a power tool.
SOLUTION: The trigger 3 of an electric screw driver controls start/stop and moves the sliding contact of a variable resistor 6. An integrating circuit 7 outputs the voltage V1 at the sliding contact of the variable resistor 6 to a PWM (pulse width modulation) control section 8 while correcting it to a voltage Vi lower than V1. The PWM control section 8 outputs a PWM control signal Vo based on the voltage Vi being inputted and performs switching control of a switching element 9 based on the PWM control signal Vo thus controlling the r.p.m. of a motor 1. Since the input voltage to the PWM control section 8 is corrected by providing the integrating circuit 7, the r.p.m. of the motor 1 can be prevented from varying abruptly when it is varied from a low speed to a high speed to require a large force for holding the tool or to cause a come-out phenomenon where a screw is removed.

摘要： PROBLEM TO BE SOLVED: To provide a DC power supply for cordless power tools, capable of always outputting its maximum capacity irrespective of a preset output voltage value. SOLUTION: An output voltage is selected to matche a cordless power tool to be used, and a maximum output current value is set for the selected output voltage. Maximum capacity of the DC power supply is utilized, by setting the maximum output current value in such a way that, the lower the selected output voltage, the larger the maximum output current value becomes, specifically the product of the maximum output current multiplied by the selected output voltage becomes approximately constant. As long as the output current remains below the maximum output current, the connected cordless power tool is controlled by the constant voltage. If it exceeds the maximum output current, it is switched to the control by a current equal to or lower than a constant current of the maximum output current to protect the DC power supply against overload.

摘要： PROBLEM TO BE SOLVED: To shorten the charging time of a battery and lengthen its cycle life by selecting an appropriate charging current corresponding to the cooling of a battery pack with a cooling fan.
SOLUTION: When a battery temperature gradient is smaller than a first predetermined value in which a battery temperature decreases and which may be regarded as having a cooling effect after a predetermined time has passed since charging start, this charging device increases the charging current. When the battery temperature gradient is larger than the first predetermined value and is a second predetermined value or more in which the battery temperature increases and which may not be regarded as having the cooling effect, the charging device decreases the charging current. When the battery temperature gradient exists between the first predetermined value and the second predetermined value, in other words, a variation in the battery temperature is small, the charging current value is taken as appropriate for the battery life of the battery pack, thus preventing the charging current from being switched.
