  • Patent number: 11111968
    Abstract: A clutch unit includes a clutch having a clutch spring, a motor that generates an actuation driving force for actuating the clutch, an output shaft that transfers the clutch reaction force to the clutch and receives an elastic restoring force of the clutch spring as a clutch reaction force, and a spring that inputs an assist force for assisting the actuation driving force to the output shaft. In switching the clutch from an engaged state to a disengaged state, the output shaft receives the assist force before receiving the clutch reaction force, whereas in switching the clutch from the disengaged state to the engaged state, the assist force becomes zero after the clutch reaction force becomes zero.

  • Patent number: 11097805
    Abstract: An electric assist bicycle and a drive system therefor includes a controller that includes control modes in which different assist ratios are calculated as control modes of the electric motor, and that stores a mode change condition that determines a change of the control mode. The controller performs the mode change when a pedal is located between an angular position that follows by 45 degrees a lowermost position of a locus of the pedal and an angular position that precedes by 45 degrees the lowermost position. Accordingly, the mode change is performed when the pedaling force exerted by a rider is relatively low such that the rider does not feel uncomfortable due to a rapid change of the load applied to the rider.

  • Patent number: 11096320
    Abstract: A plurality of nozzles are arranged at intervals of a center-to-center distance along a circumferential orbit around the predetermined rotation axis integrally. The nozzle that is positioned at the working position is changed by rotating the plurality of nozzles around the predetermined rotation axis. At that time, regardless of the manner in which the nozzle positioned at the working position is changed, the nozzle approaching the working position, and the nozzle moving away from the working position, move within an imaging target range having a width smaller than twice the center-to-center distance with the working position as the center along the circumferential orbit. Then, a camera images the nozzle which is moving within the imaging target range. Thus, it is not necessary to temporarily stop the nozzle for imaging, and as a result, imaging of the nozzles is performed efficiently.
