  • Patent number: 8378600
    Abstract: An electric power tool “A” operates a working part 5 by repeating rotation of a motor 4 in a normal direction and in a reverse direction one or more times. The motor 4 includes a brushless motor. Sensors H for detecting a position of a rotor 15 are provided on the motor 4 so as to be advanced by an electrical angle of 30°±?° from an intermediate position between respective stator teeth 16 in a direction of the normal rotation of the rotor 15. A control part 20 for controlling the rotation of the motor 4 controls a driving signal of the motor 4 based on the results of detection by the sensors H. Moreover, the control part 20 selects a detection signal of the sensors H so that relation between the rotor 15 and the detection signal of the sensors H is equivalent in either of the normal rotation and the reverse rotation of the rotor 15.

  • Patent number: 8251104
    Abstract: In a reinforcing bar binder in which a wire reel around which a reinforcing bar binding wire is wound is rotatably housed in a housing chamber in a binder main body, the wire is pulled out from the wire reel and wound around reinforcing bars, and the reinforcing bars are bound by twisting the wound portion, an opening is formed through one of both side walls of the housing chamber at a position corresponding to a shaft receiving portion formed on the wire reel. On the one side wall, a reel receiver which is supported so as to come into and come out from the opening is fitted to the shaft receiving portion of the wire reel when it is pushed into the inside of the side wall. A reel stopper moves along the wall surface of the one side wall and can engage with the reel receiver fitted to the shaft receiving portion. A leaf spring urges the reel stopper engaged with the reel receiver to the pushing-in side.

  • Patent number: 8033303
    Abstract: Two guide pins 11 and 12 formed upright in a guide plate 7 are received in guide pin fitting holes 13 and 14 formed in a guide member 8. Fixed screws 23a and 23b are screw-connected to the guide pins 11 and 12. One guide pin 12 is fitted to the corresponding guide pin fitting hole 14 with a play. Screw holes 20 and 21 are formed through the inner surface of the guide pin fitting hole 14 and the outer surface of the guide member 8. An angle of the guide member 8 with respect to the guide plate 7 is adjusted by allowing front ends of embedded screws 22a and 22b respectively screw-inserted in the screw holes 20 and 21 to respectively engage with a peripheral surface of the guide pin 12.
