Abstract: The disclosed invention relates to a foil type fluid bearing including a foil assembly. The foil assembly supports a journal within a stationary retaining member and includes a top foil that is disposed on the inside in the radial direction, three mid foil layers that are disposed outside the top foil, and corrugated bump foils disposed outside the mid foil layers. When the journal is radially displaced, a large frictional damping force is generated between the three mid foil layers, thereby enhancing the function of supporting the journal. Moreover, layering the three mid foil layers can increase the rigidity against a load in the radial direction, thus preventing the top foil from deforming in a wavelike manner and thereby allowing the function of the foil type fluid bearing to be reliably exhibited.

Abstract: A rectifying section 2, and a DCDC converter 3 which lowers an input DC voltage and then outputs the voltage are disposed between an AC generator 1 and a load 4. When the output voltage Vt of the AC generator 1 is gradually lowered with starting from E0, the output power P is increased, and is maximum at Vt=V12. When the output voltage Vt is further lowered, the output power P is reduced. As an operating point at which the same output power P is obtained, there are a point of Vt=V11, and that of Vt=V13. The operation of the DCDC converter 3 is controlled so as to operate at the point of Vt=V13 where the output current I is lower.
