20120199372 | IMPACT TOOL - According to an aspect of the present invention, there is provided an impact tool including: a motor; a hammer connected to an output portion of the motor; and an anvil to be struck by the hammer in a rotation direction and having a rotary shaft, the hammer striking the anvil in the rotation direction by driving the motor in pulses, wherein the anvil is provided in front of the hammer, wherein the hammer is driven in pulses by the motor, and wherein a rotation angle of the hammer is substantially proportional to a rotation angle of the motor. | 08-09-2012 |
20120279736 | IMPACT TOOL - According to an aspect of the present invention, there is provided an impact tool including: a motor drivable in an intermittent driving mode; a hammer connected to the motor; an anvil to be struck by the hammer to thereby rotate/strike a tip tool; and a control unit that controls a rotation of the motor by switching a driving pulse supplied to the motor in accordance with a load applied onto the tip tool. | 11-08-2012 |
20120292070 | ELECTRIC TOOL AND COMMUNICATION PLUG FOR ELECTRIC TOOL - An electric tool including: a motor configured to drive a front end tool; a control device configure to control rotation of the motor; a storage part configured to store a method of driving the motor by the control device; and a communication terminal to which a communication line for reading or writing information of the storage part is configured to be connected. | 11-22-2012 |
20130075121 | IMPACT TOOL - An impact tool including: a motor; a housing that accommodates the motor; a hammer rotated by the motor in a rotating direction; an anvil struck by the hammer in the rotating direction; an end tool holding portion connected to the anvil and protruding from a front part of the housing; and a load receiving portion that receives a load of the hammer in a rear direction. | 03-28-2013 |
20130333910 | IMPACT TOOL - According to one embodiment, an impact tool includes: a motor; and a hammer that is connected to the motor and that has a striking-side surface; and an anvil that is journalled to be rotatable with respect to the hammer, that has a struck-side surface and that provides a striking power to a tip tool, wherein the motor is drivable in: a first driving mode in which the motor is continuously driven in a normal rotation; a second driving mode in which the motor is intermittently driven only in the normal rotation; and a third driving mode in which the motor is intermittently driven in the normal rotation and in a reverse rotation. | 12-19-2013 |
20140049204 | ELECTRIC WORKING MACHINE - An electric working machine including: an input part; a control unit configured to control a motor in accordance with an operation amount of the input part; and a switching part; wherein, when a predetermined operation is performed to the switching part, the control unit shifts to a fixed control mode in which the motor is controlled in accordance with an operation amount of the input part at the time when the predetermined operation is performed to the switching part, irrespective of an operation amount of the input part after the predetermined operation is performed to the switching part. | 02-20-2014 |
20140050600 | PORTABLE BLOWER - A brushless motor is incorporated in one of divided constituent members of a motor casing which is disassembled, and then, the divided constituent members of the motor casing which is disassembled are connected to each other into the motor casing assembled with machine screws screwed into machine screw holes. As this occurs, when a wiring of the brushless motor is held by a first stationary blade portion and a second stationary blade portion, the wiring is allowed to lead to an outside of an outer cylindrical portion through a gap defined between the first stationary blade portion and the second stationary blade portion. | 02-20-2014 |
