摘要： A rotary tool includes an externally operable operation switch; a motor serving as a power source; a power transfer block for transferring the rotation of the motor; a load detection unit for detecting an amount of load of the motor; and a control unit for controlling the motor. The control unit is configured to perform an operation control by which the motor is controlled so that a rotation speed of the motor is increased in proportion to the operation amount of the operation switch and a feedback control by which the rotation speed of the motor is controlled depending on the detection result of the load detection unit. The control unit inhibits the feedback control during the time when the operation amount of the operation switch is equal to or less than a threshold and performing the feedback control only when the operation amount of the operation switch is greater than the threshold.

摘要： In a rechargeable electric power tool, upon changeover of a trigger switch, a microcomputer determines the magnitude relation between the detected temperature outputted from the first thermistor and the first temperature threshold value, the second temperature threshold value and the third temperature threshold value, and the magnitude relation between the first calculated temperature increase rate and the first preset temperature increase rate. If the detected temperature is determined to be greater than the first temperature threshold value or if the first calculated temperature increase rate is determined to be greater than the first preset temperature increase rate after the detected temperature has been determined to be greater than the second temperature threshold value, the microcomputer is set in a limited operation mode in which the revolution number of the motor is limited to a predetermined value or less.

摘要： A charging device includes a charging unit; a detection unit for detecting a temperature and a temperature increasing rate of a rechargeable battery; a controller for controlling the charging unit to supply a charging current to the rechargeable battery; and a compensating unit for setting a value of the first threshold to be greater if the temperature of the rechargeable battery at the time of mounting the rechargeable battery on the charging device is equal to or smaller than a second threshold and smaller if otherwise. The charging unit stops supplying the charging current to the rechargeable battery if the temperature increasing rate is equal to or greater than a first threshold.

摘要： An electric power tool includes a tool body and a battery pack removably mounted to the tool body. The battery pack is used as a power source of the tool body. The electric power tool further includes a lock unit for keeping the battery pack mounted to the tool body and an interrupter switch for interrupting the operation of the tool body when the lock unit does not keep the battery pack mounted to the tool body. Accordingly, the electric power tool is not operable when the battery pack is not completely mounted to the tool body.

摘要： A constant-current battery charger includes a power supply for supplying a charge current to a secondary cell, and a current monitor for monitoring a charge current being supplied to the cell. A controller is included for varying the charge current in accordance with the monitored charge current. The controller calculates a current difference between a predetermined target current and the instant charge current, and generates a demand of varying the charge current at a first charge rate when the current difference is out of a predetermined range, and varying the charge current at a second charge rate when the current difference is within the predetermined range. The controller generates the demand repeatedly at regular or varying intervals for varying the charge current. The first charge rate is set to be higher than the second charge rate in order to make a rapid charging until it comes close to the target current. Since the current difference between the instant charge current and the target current is relied upon to switch the charge rate between the first and second charge rates, the switching can be made at an exact timing truly indicative of the condition of the battery, which enables a rapid charging, yet assuring to complete the charging successfully.
