摘要： A spring-type fastener driving tool includes a plunger having a blade that drives in fasteners, a spring that urges the plunger downwards and is capable of being compressed upwards, a spring compression mechanism unit that includes a drum that causes the plunger to move in a compression direction of the spring based on rotational force of a motor, a reduction mechanism unit, and a one-way clutch than prohibits reverse rotation of the motor. Reverse rotation of the drum due to the urging force of the spring is prevented by providing the one-way clutch between an input side rotating shaft of the reduction mechanism unit and a rotation output shaft of the motor.

摘要： A combustion-powered nail gun drives nails into a workpiece when both a head switch and a trigger switch are turned ON while a safety switch is turned ON. The nail driving operation cannot be performed if the safety switch is not ON even if both the head switch and the trigger switch are ON. The head switch is turned ON when a push lever is urged against the workpiece. Fuel/air mixture in a combustion chamber is ignited when the head switch and the trigger switch are turned ON irrespective of an order in which the head switch and the trigger switch are turned ON, whereby “successive-shot driving” can be performed in which the trigger switch is maintained in its ON position while successively driving a plurality of nails at different locations of the workpiece by repeatedly pushing and releasing the push lever toward and away from the workpiece.
摘要翻译：当安全开关打开时，头戴式开关和触发开关均打开时，燃烧式电动钉枪将钉子驱动到工件中。如果头部开关和触发开关均为ON，则安全开关不亮时，不能执行指甲操作。当推杆被推压到工件上时，头部开关打开。当头开关和触发开关接通时，燃烧室中的燃料/空气混合物被点燃，而与头开关和触发开关接通的顺序无关，由此可以执行“连续喷射驱动”，其中触发开关保持在其接通位置，同时通过反向推动和释放推动杆朝向和离开工件，在工件的不同位置连续地驱动多个钉子。

摘要： Even when a transient decrease has arisen in a battery voltage VBAT of a battery pack at startup of a motor that drives a flywheel, a power terminal Vcc and a reset terminal RES (or an input terminal IN of a reset IC) of a microcomputer are replenished with a normal voltage by the voltage accumulated by a capacitor of the backup power circuit, and hence a controller can maintain normal operation without involvement of faulty operation. As a result, even the battery pack whose battery has a smaller amount of remaining energy can be effectively utilized as the power source of an electric driving machine.
摘要翻译：即使在驱动飞轮的电动机起动时电池组的电池电压V BAT发生瞬时下降，电源端子Vcc和复位端子RES（或输入端子IN 微计算机的复位IC）由备用电源电路的电容器累积的电压补充正常电压，因此控制器可以保持正常工作而不涉及故障操作。结果，即使电池具有较小的剩余能量的电池组也可以有效地用作电动驱动机的电源。

摘要： To provide inexpensive and economic battery chargers with excellent productivity, a control circuit board for the battery charger is produced so as to be usable in common for both the battery chargers with a cooling device and the battery chargers without a cooling device. In the control circuit board, a cooling device detection circuit is provided for detecting whether or not the cooling device is provided. An average charge current to be applied to a battery pack to be charged is controlled depending on whether or not the cooling device is provided. The average charge current is further controlled depending on the type of the battery pack, i.e., whether it is of a small rated capacity or of a large rated capacity, and on a rate of change in battery temperature at the time of start of charging.
