摘要： In an apparatus for manufacturing a fluid dynamic bearing, a housing portion defines a first work area. A vacuum pump discharges air in the first work area. A lubricant discharge device is arranged in the first work area, and discharges a lubricant into an inlet of a reservoir for storing the lubricant of the fluid dynamic bearing. At least one aperture is provided in the housing portion. A first door closes the aperture and a second door closes the aperture. Between the first door and the second door, when both have closed the aperture, a second work area is formed where the fluid dynamic bearing is placed.

摘要： PROBLEM TO BE SOLVED: To prevent a movable structure from tilting due to offset load of the movable structure in a guide for guiding the movable structure by forming a guide face on a base in a machine tool or the like and causing a sliding surface formed on the movable structure to slide on the guide face via a lubricating oil. SOLUTION: The guide includes the guiding face 11 formed on the upper surface of a guiding part of a bed in the machine tool, and sliding surfaces 12A and 12B provided on the lower surface of a column 7 oppositely to the guide face 11 and sliding via the lubricating oil on the guide face 11. A pressure relief groove 17 is formed as a pressure relieving means for equally dividing the sliding surface 12B into four in the longitudinal direction on the sliding surface 12B where small offset load of the column 7 works, and its contact surface shape is made asymmetric between the sliding surfaces 12A and 12B to make the magnitude of dynamic pressure occurring by movement of the column 7 correspond to the magnitude of the offset load working to each of the surfaces, thereby preventing the column 7 from being tilted.

摘要： PURPOSE:To prevent a dynamic unit from being scratched by mounting a magnetic unit on the cover of a motor having a dynamic spindle, securing the spindle, and transporting it. CONSTITUTION:When the shaft of a motor is rotated, gaps between a shaft 3 and a cylindrical portion 4a, and between the shaft 3 and a thrust shaft housing 5 become several mumm. - several tens mumm. by a herringbone groove 3a and a spiral groove 3b of the shaft 3. When the shaft 3 vibrates to scratch the grooves 3b, 3a at transporting time, the prescribed performance cannot be achieved. When a magnet 10 is mounted on a dustproof cover 6 at the transporting time, the shaft 3 is attracted to a magnetic plate 9, and can be transported without vibration.

摘要： The present invention provides a process for producing a saturated aliphatic hydrocarbon prepared using an ±-olefin as a raw material and represented by the general formula (1), including the steps of: (I) producing a vinylidene olefin by dimerizing the ±-olefin in the presence of a metallocene complex catalyst; (II) further dimerizing the vinylidene olefin in the presence of an acid catalyst; and (III) hydrogenating the obtained dimer. Further, there are provided a lubricant composition containing the saturated aliphatic hydrocarbon compound produced by the above process, a bearing oil consisting of the lubricant composition, and making use of the same, a bearing and gyral equipment. The saturated aliphatic hydrocarbon compounds produced by the process of the present invention have low-temperature fluidity, exhibiting low evaporativity, and excellent in thermal stability and oxidation stability. Thus, the saturated aliphatic hydrocarbon compounds are suitable for use as, for example, a base oil of lubricant composition for hydraulic pressure, turbine, working machine, bearing, gear, metal-working, etc.
