Title: Innovations of Toshihiko Kushida
Introduction
Toshihiko Kushida is a notable inventor based in Osaka, Japan. He has made significant contributions to the field of tightening devices, holding a total of nine patents. His work focuses on enhancing the efficiency and reliability of fastening mechanisms.
Latest Patents
Kushida's latest patents include a tightening device and a tightening method. These innovations allow for the verification that a fastening member has been secured to a desired set torque or greater after being tightened, without the need to loosen the fastening member. The tightening device executes a first tightening process by adjusting the output of a motor once the measured torque reaches a preset first control start torque. This process ensures that the measured torque gradually reaches a preset first set torque through repeated increases and decreases in torque. The device then blocks the power supply to the motor when the first set torque is achieved. Following this, a second tightening process is initiated, which drives the motor at an initial output that is lower than in the first process. This method also involves adjusting the motor output after the measured torque reaches a preset second control start torque, ensuring that the measured torque reaches a preset second set torque in a similar phased manner.
