    摘要: A microinjection apparatus is designed to introduce the transfecting material into the transductant by inserting a minute injection needle (11) into the transductant and includes a container position adjuster (1), an imaging device (2), a position determiner (3) and a plurality of transporters (4). The container position adjuster adjusts the position of a container (12) accommodating therein the transductant. The imaging device captures through a lens (2a), an image of an inside of the container, which has been adjusted in position by the container position adjuster. The position determiner determines the position of the transductant from the image obtained by the imaging device. The plurality of the transporters are operable to transport the plural injection needles, individually for each of those injection needles, in dependence on the position information obtained by the position determiner.

    摘要: This centrifugal blood pump apparatus includes an impeller provided in a blood chamber, a permanent magnet provided in one surface of the impeller, and a permanent magnet provided in an inner wall of the blood chamber, for attracting the permanent magnet. A centerline of the permanent magnet is arranged at a position different from that of a centerline of a sidewall of the blood chamber such that a rotation centerline of the impeller matches the centerline of the sidewall of the blood chamber during pump operation. Therefore, high torque transmission efficiency is obtained.

    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.

    摘要: The device includes a rolling bearing unit supporting a radial load and a magnetic bearing unit supporting an axial load and/or a bearing preload; an electromagnet fitted to a spindle housing so as to confront, on a non-contact basis, a flange shaped thrust plate mounted on a main shaft; a motor rotor of a motor for driving the shaft, and a motor stator opposed to the rotor, the shaft being driven by magnetic or Lorentz forces developed between the rotor and the stator; and a sensor detecting an axial force acting on the bearing unit, and a controller controlling the electromagnet. In this device, the stiffness of a composite spring formed by the bearing unit and a support system for the bearing unit is chosen to be higher than the negative stiffness of a composite spring of a motor part comprised of the electromagnet and the motor.

    摘要: A centrifugal blood pump apparatus includes an impeller provided in a blood chamber, first and second permanent magnets provided in one surface and the other surface of the impeller respectively, a third permanent magnet provided in an inner wall of the blood chamber, and a magnetic element and a coil for driving the impeller to rotate with a diaphragm being interposed. First and second grooves for hydrodynamic bearing different in shape and depth from each other are formed in the inner wall of the blood chamber facing the impeller, and third and fourth grooves for hydrodynamic bearing different in shape and depth from each other are formed in the diaphragm facing the impeller. The second and fourth grooves for hydrodynamic bearing generate high hydrodynamic pressure when the impeller is activated to rotate, while the first and third grooves for hydrodynamic bearing generate high hydrodynamic pressure when the impeller steadily rotates.
