摘要： A combustion-powered driving tool for driving nails or other fasteners in which the starting characteristics of a motor in the tool are improved by varying the amount of voltage applied to the motor when starting the motor and during normal operations so that the motor is driven to reach the rotational speed required in normal operations quickly. Therefore, the combustion-powered driving tool does not require the use of an expensive low-inertia motor, but can use a relatively inexpensive core-type motor or the like with inferior starting characteristics, while improving the work efficiency and user-friendliness of the combustion-powered driving tool.

摘要： In a DC power source unit that can selectively charge a battery pack and supply DC power to a cordless power tool through an adaptor shaped like the battery pack, a battery pack insertion space, into which the battery pack is inserted to charge, is substantially sealed or closed so as not to be in fluid communication with the inner space in which the circuit components are disposed. Cooling air for cooling the circuit components are not disturbed by disturbing air flow which may otherwise be created if the battery pack insertion space is not sealed.
摘要翻译：在直流电源单元中，可以选择性地对电池组进行充电并且通过形状如电池组的适配器向无绳电动工具提供直流电力，电池组插入其中以充电的电池组插入空间基本上被密封或关闭，以便不与设置电路部件的内部空间流体连通。用于冷却电路部件的冷却空气不会受到干扰气流的干扰，如果电池组插入空间未被密封，否则可能产生气流。
