  • Patent number: 5628267
    Abstract: An oscillation suppression device is provided for attenuating oscillation of an object to be controlled by a gyro torque of a control moment gyro having a flywheel rotating at a high speed. The oscillation suppression device includes an angular velocity detector for detecting an oscillation angular velocity of the object to be controlled. A control unit is connected to a gimbal shaft of the control moment gyro for controlling the angular velocity .theta. of the gimbal of the control moment gyro so as to absorb an external torque generated in the object to be controlled. The control unit operates in response to the oscillation angular velocity .PHI., which is detected by the angular velocity detector.

  • Patent number: 5626751
    Abstract: A filter unit comprises a metallic supporting plate possessed of stepped through holes opening with a larger diameter in one main surface and with a smaller diameter in the other main surface (wherein the diameter ratio of larger-diameter openings to smaller-diameter openings is desired to be in the range of 1:0.01 to 1:0.5) or a pressureproof supporting plate having in one surface thereof inclined liquid flow grooves arranged in a radial pattern and concentric circular liquid flow grooves adapted to intersect the radially arranged liquid flow grooves and a membrane filter disposed on the surface of the supporting plate containing larger-diameter openings or liquid flow grooves. This filter unit is ideally used for finely dividing and uniformly sizing suspended lipid particles assuming a definite average particle size and a specific particle size distribution.
