Abstract: An artificial heart has a driving section, a nozzle section, a pump section for insertion into a ventricle of a human heart, and a sealing section forming a seal for a driving shaft extending from the driving section for driving the pump section. A sealing liquid chamber filled with a sealing liquid is formed around the driving shaft between the sealing mechanism and the driving section. The sealing liquid in the sealing liquid chamber maintains the sealing mechanism in a liquid-tight state and lubricates the sealing mechanism, whereby blood is prevented from entering the driving section. Even if blood happens to enter the driving section, the blood is mixed with the sealing liquid and does not coagulate. Thus, the operation of the artificial heart is not suppressed.

Abstract: In an apparatus for driving and controlling a power window according to the present invention, a blanking period is provided to stop the comparison between a variation amount of motor current and a threshold value, during a predetermined period of time T after the drive of the motor has been started. The catching of a foreign object is detected based on the motor current value in the latter half Tm of the blanking period, and is detected based on the variation amount of the motor current after the blanking period. Erroneous operation due to noise at the beginning of the drive of the motor is prevented, and the catching of a foreign object is reliably detected.
