    Abstract: A bicycle controller and a bicycle controlling method reduces a distance a bicycle travels before a motor is stopped regardless of whether pedaling is stopped in a state where a rotation speed of the crank is high. The bicycle controller includes an electronic control unit that controls a motor, which assists pedaling of a bicycle, based on a manual driving force and angle information related to an angle of a crank of the bicycle. If the crank is rotated by a predetermined angle or greater in a state where the manual driving force is less than or equal to a predetermined threshold value while the motor is driven, then the electronic control unit stops the motor.

  • RESISTANCE SPOT WELDING METHOD
    Publication number: 20180281102
    Abstract: A stored time variation curve and cumulative amount of heat generated of each step are each used as a target. In the case where a time variation of an instantaneous amount of heat generated per unit volume differs from the time variation curve in any of the steps, a current passage amount is controlled in order to compensate for the difference within a remaining welding time in the step so that a cumulative amount of heat generated per unit volume in actual welding matches the stored cumulative amount of heat generated in the test welding. Further, in the case where expulsion is detected in any of the steps, then in subsequent welding, the cumulative amount of heat generated per unit volume used as the target is reduced, and the current passage amount is adjusted in accordance with the reduced cumulative amount of heat generated per unit volume.
