    摘要: A hydrodynamic bearing system comprises a shaft, a sleeve rotatably fitted on the shaft and a thrust plate fixed to the sleeve and acting to support one end of the shaft in a thrust direction. First shallow grooves are formed in at least one of fitted surfaces of the shaft and of the sleeve to support one of the shaft and the sleeve with respect to the other in a radial direction, and a second shallow groove is formed in at least one of the shaft and the thrust plate with respect to the other in a thrust direction. The thrust plate is made of material including resin material as a main component and has an outside periphery portion with a thickness thicker than that of an inside periphery portion thereof.

    摘要: An optical device functioning as a variable apex angle prism and suitable to be incorporated in an image stabilizing apparatus for an optical apparatus is constituted by a pair of transparent circular plates disposed oppositely spaced from each other, a connecting member attached to the circular plates so as to define a closed space in combination with the circular plates and deformable under application of an external drive force, and a transparent substance disposed within the closed space. The transparent substance comprises at least one compound selected from the group consisting of polyether-modified organopolysiloxane, polyether alcohol-modified organopolysiloxane and fluorine-containing compounds.
