Abstract: A method and apparatus for transmitting/receiving data in which a color gamut identifier is included using a synchronization section of an analog image signal are provided. In the method, it is determined whether an analog image signal is a color gamut signal. If the analog signal is a color gamut signal, a color gamut identifier is generated using a synchronization section of the analog image signal, and the analog image signal is transmitted after the color gamut identifier is added to the synchronization section of the analog image signal.

Abstract: A fluid bearing apparatus in which dynamic pressure generating grooves are subjected to a change in shape to increase the amount of fluid to be introduced into the grooves of a thrust bearing. In the fluid bearing apparatus, in order to introduce an increased amount of fluid into the dynamic pressure generating grooves formed on a side of the thrust bearing which supports a rotating shaft, a fluid inlet of the dynamic pressure generating grooves is shaped with arc portions for the fluid to be easily introduced thereinto. Accordingly, a fluid pressure in the dynamic pressure generating grooves is increased.

Abstract: A journal bearing apparatus capable of varying the clearance between a bush which protrudes from the inner surface of a sleeve in which a rotation shaft is inserted and the outer surface of the rotation shaft, in the longitudinal direction of a first dynamic pressure generating groove. Moreover, a journal bearing apparatus is capable of varying the clearance between one end of the rotation shaft and the surface of a thrust bearing, in the diametral direction of a second dynamic pressure generating groove. The clearance becomes wider towards the central part from the ends of the bush, or towards the central part from the edge parts of the surface of the thrust bearing. The shape of the end of the bush or the thrust bearing is preferably a circular arc. Thereby, the fluid pressure on the rotation shaft which faces the first and second dynamic pressure generating grooves is uniform.

Abstract: A fluid bearing apparatus includes a thrust load supporting portion formed between an external side surface of a fixing shaft and an internal side wall of an opening in a bushing; the surface and wall facing each other. The thrust load supporting portion includes a ball inserting groove formed on the external side surface of the fixing shaft and/or the internal side wall of the bushing and a ball inserted into the ball inserting groove. The upper end portion of the shaft is lower than the upper end portion of the bushing. Since the thrust load is supported by the balls instead of by the upper end portion of the fixing shaft, it is possible to prevent movement of the fixing shaft when the fluid bearing apparatus starts to rotate. The frictional resistance of the upper end portion of the fixing shaft can be reduced when the fluid bearing apparatus starts to rotate and stops its rotation.
