| 20130199812 | HANDHELD WORK APPARATUS - A handheld work apparatus has a combustion engine ( | 08-08-2013 |
| 20140034346 | SPEED CONTROL DEVICE FOR GOVERNING THE SPEED OF A PNEUMATIC POWER TOOL - A speed control device for limiting the idle and operating speed of a pneumatic power tool driven by an air turbine ( | 02-06-2014 |
| 20140352995 | ELECTRIC POWER TOOL - An object of the present invention is to provide an electric power tool capable of automatically changing the rotating speed of an electric motor in accordance with operation conditions. The electric power tool | 12-04-2014 |
| 20150047866 | ELECTRIC TOOL AND FASTENING METHOD USING THE SAME - An electric tool in which a pulsating input voltage is configured to be supplied to a drive circuit of a motor, the electric tool including: a rotation speed detection unit configured to detect a rotation speed of the motor, characterized in that the electric tool further includes: a control part configured to vary a determining value for determining whether the rotation speed of the motor satisfies a predetermined condition or not, so as to be synchronous with a pulsation cycle of the input voltage supplied to the drive circuit. | 02-19-2015 |
| 20150122525 | ELECTRIC TOOL FOR OUTPUTTING TORQUE - An electric tool for outputting torque includes a housing and a motor disposed in the housing, a rotatable base configured to be driven by the motor to rotate about a first axis, at least one impact block rotatably connected to the rotatable base, an output shaft rotatably connected in the housing and configured to rotate about the first axis under intermittent impact of the impact block, a locking member which, when at a first position, locks the impact block to prevent it from impacting on the output shaft and which, when at a second position, releases the impact block to allow it to rotate freely, a biasing assembly for biasing the locking member to the first position, a regulating assembly for regulating a biasing degree exerted by the biasing assembly on the locking member, and a control assembly operable by the user from outside the housing to control the regulating assembly. The locking member is disposed at least partially in the rotatable base. | 05-07-2015 |
| 20150328759 | IMPACT TOOL - An electrical hammer ( | 11-19-2015 |
| 20160107297 | ELECTRIC POWER TOOL - An electric power tool in one aspect of the present disclosure comprises a motor, a hitting mechanism, a hitting detector, and a control unit. The control unit is configured to set a control amount of the motor so that the motor rotates at a lower speed than a speed in the target rotation state during an initial driving period, and switch the control amount to a final control amount corresponding to the target rotation state when the initial driving period elapses. The initial driving period is a period from when generation of a hitting force is detected by the hitting detector until a predetermined first time period elapses, after the motor is started driven. | 04-21-2016 |
| 20160151845 | RECIPROCATING ELECTRIC POWER TOOL | 06-02-2016 |
