    摘要： Provided is a shaft member for a fluid dynamic bearing device, which is excellent in wear resistance and which can exert a high dynamic pressure effect. A shaft material (11) is rolled to form a recess (7) for causing a dynamic pressure effect of a lubricating oil in a radial bearing clearance (6). In this case, in a surface layer portion (14) of the recess (7) to be formed in an outer peripheral surface (11a) of the shaft material (11), a first hardened layer (14a) is formed by rolling. At the same time, also in a surface layer portion (15) of a surrounding region (8) of the recess (7), a first hardened layer (15a) is formed by rolling at a partial region thereof. After the recess (7) is formed by the rolling, barreling is applied to the shaft material (11). As a result, an outermost surface layer portion of the surface layer portion (15) is formed with a second hardened layer (15b) by the barreling. A hardness of the second hardened layer (15b) formed in the surrounding region (8) is higher by 50 Hv or more and 200 Hv or less than that of the first hardened layer (14a) formed in the recess (7).

    摘要： A spindle unit which can offset any displacement of the spindle due to thermal expansion and which can adjust the preload on the bearings according to the revolving speed of the spindle. Between the outer casing and the spindle are provided a high-rigidity elastic member and a pressure chamber connected to an oil pressure control valve. A displacement sensor provided at the end of the spindle and a tachometer are connected to the pressure control valve. As the revolving speed of the spindle increases, oil pressure is introduced into the pressure chamber to reduce the preload. By reducing the preload, the spindle moves axially, thus offsetting its displacement due to thermal expansion.

    摘要： A portable computer including a CPU, a detachable hard disk pack which is connectable to a system bus of the portable computer, and a hard disk pack replacement detector which detects, in a power-Off state, a detachment of the disk pack and sets a signal in a status register indicating the detachment of the disk pack. In response to a power-ON state, the CPU reads the status register to determine whether the disk pack had been detached during the power-OFF state and, if so, disables a resume flag so that operation does not resume at the operating state of the portable computer which existed immediately preceding the power-OFF state.

    摘要： A rolling contact bearing assembly comprises an inner race member adapted to be mounted on a rotatable element and including a spacer disposed axially adjacent the inner race. This inner race member is formed with a lubricant reservoir for accommodating a lubricant and a lubricant flow passage communicating the reservoir with a space defined between the inner and outer race, in which space rolling elements are accommodated. At least a portion of said lubricant flow passage is defined by minute interstices which are formed by surface roughness left by surface roughening at an interface between mutual contact faces of a plurality of component parts forming the inner race member.
