摘要： A main adjusting circuit obtains an intermediate value of maximum and minimum values of an output from a position sensor when a rotational shaft is brought into contact with a ball bearing for protection by reduction in a proportional constant K of a proportional circuit. An offset value corresponding to a difference between 0V and the intermediate value of the vibration is added to or subtracted from the output from the sensor for initial adjustment.

摘要： An electric vehicle includes a slip ratio estimator that estimates a slip ratio based on rotational frequencies of respective driven and drive wheels. The vehicle also includes a disturbance observer that determines an estimate of a torque attributable to external force. The vehicle also includes an estimator that may estimate an entire torque to the drive wheel, based on a motor torque command value and the estimate of torque.

摘要： This centrifugal blood pump apparatus includes an impeller provided in a blood chamber, a first permanent magnet provided in one surface of the impeller, and a second permanent magnet provided in an inner wall of the blood chamber, for attracting the first permanent magnet. The attractive force between the first permanent magnet and the second permanent magnet on the opening side of a sidewall of the blood chamber is set to be smaller than the attractive force between the first permanent magnet and the second permanent magnet on the opposite side of the opening. As a result, inclination of the impeller with respect to a dividing wall during pump operation can be prevented.
