    摘要： There is disclosed an optical device capable of deforming a member connecting a pair of optically transparent parallel-faced flat plates, thus varying the mutual angle of the paired flat plates and obtaining a predetermined optical performance on the passing light beam. The connecting member is formed by connecting plural elastic members so as to form Y-shaped or modified Y-shaped cross section in a number at least equal to zero. The connecting member is formed, in at least a part of the elastic members, by one-layered or plural-layered polymer films.

    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.
