摘要： PROBLEM TO BE SOLVED: To reduce variation in tightening toque by controlling the tightening torque by a rotation angle of a screw and automatically stopping a motor at a time point when desired tightening torque is obtained. SOLUTION: A rotary tool effects torque on a screwing tool 3 by transmitting a rotation output of the motor 2 to a hammer 22a and transmitting impact force generated by striking an anvil 22b by the hammer 22a to the tool 3. A rotation angle detecting means 34 detects a rotation angle of the motor 2. A rotation angle of the tool 3 per strike is estimated by the rotation angle detected by the detecting means 34 and strike timing detected by a strike detecting means 36. A tightening determination means 33 instructs a motor control means 30 to stop the motor 2 when a condition where the rotation angle of the tool 3 for one strike does not reach a specified rotation angle per strike is detected by a defined number of times.

摘要： PROBLEM TO BE SOLVED: To provide a power tool system capable of improving the convenience in use of a power tool using a secondary battery as its power supply.
SOLUTION: Each time a power tool M is held in the holder H after the end of one job, third and fourth terminals 30 and 31 of the holder H touch first and second terminals 6 and 7 of the battery pack M2 of the power tool M for electrical connection, so that the secondary battery 2 of the battery pack M2 is charged by the charger BC. Therefore, the user need not remove the battery pack M2 from the tool body M1 to charge. Further, the capacity of the secondary battery can be relatively smaller. This can improve the operability of the power tool M and always make the secondary battery 2 be fully charged whenever it is used. The output torque of the power tool M can be stable since the supply voltage is always the same. As the result, this can improve the convenience in use of the power tool M using the secondary battery 2 as the power supply.

摘要翻译：解决的问题：提供能够提高使用二次电池作为电源的电动工具的使用方便性的电动工具系统。
解决方案：每次在一个作业结束后，将电动工具M保持在保持器H中，保持器H的第三和第四端子30和31接触电池组M2的第一和第二端子6和7 用于电连接的电动工具M，使得电池组M2的二次电池2由充电器BC充电。因此，用户不需要从工具体M1中取出电池组M2来充电。此外，二次电池的容量可以相对较小。这可以提高电动工具M的可操作性，并且在使用时总是使二次电池2充满电。由于电源电压始终相同，电动工具M的输出转矩可以稳定。结果，这可以提高使用二次电池2作为电源的电动工具M的使用方便性。版权所有（C）2008，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To suppress overcharge when recharge of a fully charged battery is repeated, in a charger which performs constant-current charge in at least a part of a charging process like constant-current/constant-voltage charge.
SOLUTION: Preliminary charge is performed at a current value I2 only for a predetermined period T1, immediately after starting charge, before performing the regular constant-current charge, wherein the value I2 is smaller than a current value I1 used in the constant-current charge. When a target voltage V1 is reached in the preliminary charge at which the constant-current charge and the constant-voltage charge are switched, the charger judges the battery to be fully charged, and suspends charging. With such constitution, if the fully charged battery is loaded, the target voltage V1 may be exceeded in the constant-current charge by the current value I1 of a larger current as before, whereas in the charger, a charging electric charge flowing into the battery at the small current value I2 is made to be reduced than before, by which the overcharge caused when the recharge of the fully charged battery is repeated is suppressed.

摘要： PROBLEM TO BE SOLVED: To make a transition from synchronous operation to brushless operation in a short time, and to suppress torque variation when a transition is made from synchronous operation to brushless operation. SOLUTION: After performing synchronous operation while increasing the commutation frequency f gradually from an initial value f0 to a predetermined value fs, a synchronous control circuit 46 temporarily switches the conduction pattern (commutates) by increasing the commutation frequency f to a frequency fs×a higher than the predetermined value fs before making a transition to brushless operation. As compared with a prior art, torque variation can be suppressed when a transition is made from synchronous operation to brushless operation, and a transition can be made from synchronous operation to brushless operation by starting the brushless motor in a short time.
