    摘要： There is disclosed a fluid filtration element having a porous core cylinder, a sectionally thick filtration cylinder fitted around the core cylinder, and end plates secured to the end surfaces of filtration cylinder. Highly densified portions are formed at the filtration cylinder ends to which the end plates are press-fitted, thereby hindering the fluid permeation. Sectionally thin protrusions erected on the end plate surfaces are cut into the highly densified portions.

    摘要： A linear motor apparatus which drives a mover of a linear motor in a stable manner, by using only information on change of relative position, without using an absolute value sensor. The apparatus has a coil array of plural phases of coils and a magnet relatively movable to the coil array, plural drivers, at least one of which being provided for each phase, to feed a current to all the same phase coils of the coil array, a sensor for measuring a change of relative position of the magnet moved by the current to the coil array, and a controller to determine the polarity of the current applied to the same phase coils based on the change of the relative position measured by the sensor, and apply a drive current to drive the magnet in a desired direction to the same phase coils.

    摘要： Provided is high-performance H.sub..infin. control technology suitable for position control or speed control of semiconductor exposure apparatus, servo writer of hard disk, etc. A series compensator in the classical control technology represented by the PID compensator is employed as a frequency weight of loop shaping, whereby the design technology in the conventional classical control can be succeeded to and a high-performance control system can be realized even for cases where there is an oscillation mode of a controlled object to become a problem on control performance in the servo band, which was difficult to realize by the classical control technology. Also, using a robust stabilizing compensator obtained from a generalized plant having constant matrix weights, a high-performance control system can be realized even for cases where there is an oscillation mode of the controlled object to become a problem on control performance in the servo band, which was difficult to realize by the conventional classical control technology.

    摘要： A stage driving system capable of positioning an object with a higher speed and a higher precision than prior systems. The system includes a base member, plural movable members provided on the base member, and a controller for controlling the plural movable members so as to substantially suppress the vibration of the base member caused by the displacements of the plural movable members.

    摘要： In an adaptive apparatus for adaptively adjusting parameters in a system, the parameters of the system are adjusted in accordance with an integral relationship. At that moment, one or both of a scalar and a matrix which depend on time are used as gains. Furthermore, adjustment in accordance with a proportional relationship is used together. Also in this adjustment, one or both of a scalar and a matrix which depend on time are used as gains.
