Abstract: A flow regulating apparatus for a porous hydrostatic bearing includes a measuring device for measuring a flow of injected gas through a bearing surface of the hydrostatic bearing to be regulated, a pattern member having a plurality of application pattern portions of different opening ratios on each of which a plurality of small holes are formed in a dispersive manner, and an application device for applying solvent on the bearing surface through the pattern member. A proper pattern portion is selected based on a flow measured by the measuring device, and the proper pattern portion and the application device are aligned with a portion of the bearing surface to which the solvent is to be applied. The solvent is then applied and this operation is repeated until the flow measured by the measuring device becomes a predetermined value.

Abstract: A method of manufacturing a porous static pressure gas bearing includes the steps of impregnating a porous material to be adjusted in injection flow rate with resin and closing vent openings, and applying a solvent for dissolving the resin to the porous material through a pattern having a predetermined opening distribution.
