  • Patent number: 9440012
    Abstract: A ventricular assist blood pump of the present invention includes: a rotational part having an impeller; and a housing which houses the rotational part therein. In the ventricular assist blood pump, a difference between a maximum flow rate and a minimum flow rate of a liquid in a state where the ventricular assist blood pump is connected to a liquid-discharge source which discharges the liquid while increasing and decreasing the flow rate of the liquid at a fixed cycle is 40% or more of a difference between the maximum flow rate and the minimum flow rate of the liquid in a state where the ventricular assist blood pump is not connected to the liquid-discharge source. A ventricular assist blood pump of the present invention can suppress the degree at which the health of a user deteriorates during long-term use compared to a conventional ventricular assist blood pump.

  • Patent number: 6933644
    Abstract: A magnetic levitation motor which rotates a rotor in a levitated state with respect to a stator by a direct-current magnetic field and stator windings. The magnetic levitation motor comprises: a direct-current magnetic field generating device (4) which forms a magnetic flux having a radial pattern with an axis at the center in a stator (2) and a rotor (3); a first stator winding (6) for generating a levitation control magnetic flux (5) to control levitation of the rotor (3) in a radial direction; and a second stator winding (7) for generating a rotating magnetic field to rotate the rotor (3). The rotor (3) is provided with a yoke portion (9) and a motor magnet (10) which are opposed to a stator core (8) of the stator (2). A part of a bias magnetic flux (11) and a part of a levitation control magnetic flux (5) form a magnetic circuit directly reaching the stator core from the yoke, thereby increasing a levitation force of the rotor.

  • Patent number: 6885121
    Abstract: 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.
