摘要： A hydrodynamic type bearing unit with enhanced moment load capacity. In the bearing unit, a radial bearing clearance and thrust bearing clearances are set at such widths that a tilted spindle member comes into contact at the outer periphery of its spindle with both axial ends of a radial bearing surface opposed thereto, as well as at the rims of both end faces of its flange portion with respective thrust bearing surfaces opposed thereto, so that the moment load can by supported by both the radial bearing part and the thrust bearing part. Specifically, the radial bearing clearance &dgr;R and the thrust bearing clearances &dgr;A are set in accordance with the expression D&dgr;R/L+&egr;≧&dgr;A≧D&dgr;R/L (where D is the diameter of the flange portion, L is the axial length of the radial bearing part, and &egr; is a machining error).

摘要： An electric direct-acting actuator is proposed which can maintain a large power increasing function without mounting a separate speed reducer. A plurality of planetary rollers (7) are disposed between the radially outer surface of a rotor shaft (5) of an electric motor and the radially inner surface of an outer ring member (1) fixed in position around the rotor shaft (5) so as to be rotatable about the rotor shaft (5) and about their own axes when the rotor shaft (5) rotates. A helical rib is defined by a rib member (9) engaged in a helical groove (8) formed in the radially inner surface of the outer ring member (1). The helical rib is engaged in circumferential grooves (10) formed in the radially outer surface of each planetary roller (7) at the same pitch as the turns of the helical rib. Thus, the rotary motion of the rotor shaft (5) is converted to a linear motion of the planetary rollers (7), so that it is possible to ensure a large power increasing function without mounting a separate speed reducer.

摘要： In a magnetically suspended type pump, an operating state of the pump can be obtained without using a pressure gauge and a flowmeter. In addition, in the case where the magnetically suspended type pump is applied to a blood pump, in order to reduce the number of connections in a flow path and to avoid thrombus formation, a correlation between current flowing in a motor and flow or a correlation between current flowing in the motor and pressure is obtained in advance, and the speed of rotation of motor is varied by a speed of rotation control circuit in response to an instruction from a CPU circuit, based on the obtained correlation between current and flow or between current and pressure, whereby flow or pressure is controlled.
