    Abstract: A tightening device and a tightening method are able to check that a fastening member has been fastened to a desired set torque or greater after being tightened, without loosening the fastening member. The tightening device executes a first tightening process of adjusting the output of a motor after measured torque that is measured by a torque detector has reached a preset first control start torque, such that the measured torque reaches a preset first set torque in a phased manner through repeated increases and decreases in torque, and blocking power supply to the motor when the measured torque reaches the first set torque, and then executes a second tightening process of driving the motor at an initial output that is less than in the first tightening process, adjusting the output of the motor after the measured torque that is measured by the torque detector has reached a preset second control start torque, such that the measured torque reaches a preset second set torque in a phased manner through repeated increases and decreases in torque, and blocking power supply to the motor when the measured torque reaches the second set torque.

    Abstract: According to one implementation, a blast treatment device includes at least one nozzle, a movement structure and at least one weight member. The at least one nozzle injects blast media. The movement structure reciprocates the at least one nozzle along a track. The at least one weight member cancels a vibration caused by reciprocating the at least one nozzle. Further, according to one implementation, a blast treatment method includes injecting blast media from at least one nozzle; manufacturing a blast treated product by reciprocating the at least one nozzle along a track; and canceling a vibration, caused by reciprocating the at least one nozzle, by at least one weight member.

    Abstract: A tightening device is able to check that a fastening member has been fastened to a desired set torque or greater after being tightened, without loosening the fastening member. The tightening device is provided with a mode switching switch for switching between a first tightening process of adjusting the output of a motor after measured torque that is measured by a torque detector has reached a preset first control start torque, such that the measured torque reaches a preset first set torque in a phased manner through repeated increases and decreases in torque, and blocking power supply to the motor when the measured torque reaches the first set torque, and a second tightening process of driving the motor at an initial output that is less than in the first tightening process, adjusting the output of the motor after the measured torque that is measured by the torque detector has reached a preset second control start torque, such that the measured torque reaches a preset second set torque in a phased manner through repeated increases and decreases in torque, and blocking power supply to the motor when the measured torque reaches the second set torque.
