摘要： A rotor includes four magnetic poles provided in a rotational direction at intervals of 90 degrees. A stator includes a winding group for rotation and a winding group for levitation. Each of the winding groups has concentrated windings spaced at intervals of 30 degrees in a rotational direction to provide induction conductive winding sections at twelve locations. Each two of the induction conductive winding sections spaced at an interval of 90 degrees among the twelve induction conductive winding sections are connected to form one winding set such that six winding sets are formed in total in each of the winding groups. Current for rotation and current for levitation are conducted through the six winding sets in the windings for rotation and levitation to perform rotation and levitation controls of the rotor.

摘要： The flux densities formed by plural electromagnet poles M1 to M12 which are arranged at a predetermined interval in a circumferential direction of a rotary body 1 at the same position in an axial direction of the rotary body 1 are gradually changed in the circumferential direction of the rotary body. Even if there is a difference between the maximum value of the flux density and the minimum value, the change of the flux densities between the adjacent electromagnet poles is small and smooth. Accordingly satisfactory detective sensitivity and detection results can be obtained.

摘要： An auxiliary artificial heart pump drive device for driving an auxiliary artificial heart pump includes first and second pump control parts which are arranged in duplexed configuration. Each pump control part controls the auxiliary artificial heart pump by outputting a drive signal to the auxiliary artificial heart pump. Each pump control part has a means which, when a failure is detected in the pump control part, electrically cuts off a path through which the drive signal is outputted to the auxiliary artificial heart pump. According to the present invention, it is possible to provide an auxiliary artificial heart pump drive device and an auxiliary artificial heart system which exhibit high availability even when a serious failure occurs by any chance without duplexing a pump device.

摘要： A hydrodynamic bearing apparatus comprises two hydrodynamic bearing sections which have a shaft member, a bearing member fit to the shaft member with a predetermined space therein, lubricants filling the space between the shaft member and the bearing member, and which are separately placed in the axial direction of the shaft member. The lubricants of the two hydrodynamic bearing sections are separated from each other by an air layer. The lubricants are pressured by hydrodynamic generating grooves formed on the hydrodynamic bearing sections such that the shaft member and the bearing member are rotatably supported in relation to each other. The hydrodynamic generating grooves separately formed on the two hydrodynamic bearing sections are formed into an unbalanced shape such that the lubricants are moved in a predetermined direction to correct the slope of the shaft member and the bearing member when rotation is suspended. Capillary sealing sections are formed in continuation to end sections of each of the two hydrodynamic bearing sections to sustain the lubricants by capillarity. The maximum amount of the lubricant in one of the capillary sealing sections, which is located downstream in the moving direction of the lubricants, is established to be larger than the moving amount of the lubricants.
