    摘要: An object of the present invention is to provide a method of manufacturing a fluid dynamic bearing device and a bearing part for a thrust bearing, both of which are applied to a flat and thin bearing part and are capable of preventing abrasion and scratching even if two parts make contact with each other. A fluid dynamic bearing mechanism 40 includes a shaft 1 functioning as an axis of rotational, a sleeve, a flange 3, a thrust plate 4, and a thrust bearing portion 22. The sleeve is disposed on the outer peripheral side of the shaft. The flange is disposed in the vicinity of the end portion of the shaft, and includes a bottom surface 3c perpendicular to a central axis direction of the shaft. A thrust receiver includes a front surface 4a opposed to the bottom surface. The thrust bearing portion is formed between the bottom surface and the front surface, and includes a plurality of thrust dynamic generation grooves 3a formed on the bottom surface. Particulates with hardness higher than that of the top surface are diffused and disposed on the bottom surface, and are then implanted in the bottom surface by applying pressure such that a portion of the particulates extends therefrom.

    摘要: An electromagnetically suspended floating floor apparatus in which a floating floor on which machines are set up is suspended from an installation floor with electromagnetic actuators so that the floating floor is spatially separated from the installation floor whereby no vibration is transmitted to equipment on the floating floor. The floating floor apparatus comprises the floating floor suspended from the installation floor at a plurality of supporting points by electromagnetic actuators, a light emitting member, fixed to a beam or a pillar, which emits a horizontal light beam, and a photosensor fixed to the installation floor which outputs a position signal representing a position of incidence of the horizontal light beam to the electromagnetic actuators. On the basis of the position signal, the electromagnetic actuators control a vertical position of the floating floor.

    摘要: A device to control vertical vibration of a building caused by seismic disturbance. Air springs are positioned and secured between the building foundation and the building superstructure to attenuate vertical vibration of the building. Vertical support rails are secured to the foundation and/or to the building superstructure on opposite sides of, and adjacent to, the air springs. Horizontal connecting brackets are rigidly secured to the air springs and slidably secured to the adjacent rails. The brackets restrain horizontal deflection of the air springs without interfering with vertical reciprocation of the air springs.

    摘要: A vibration-proof and earthquake immune mount system connecting machinery or a structure to a foundation which may be subject to external vibrations or earthquakes. The mount system includes a number of mounts operating in conjunction with a number of dampers, and both the mounts and the dampers function regardless of the direction of the external disturbance. In the mount this ominidirectionality is achieved by using a low-friction rolling contact between a ball attached to the machinery or structure and a dished surface attached to the foundation. Damping is provided by eddy current dissipation when a conductor plate attached to the structure of machinery and free to move in two directions is placed between the poles of an electromagnet which is integral with the foundation, and activated by a controller energized when a sensor detects motion of the foundation.

    摘要: A house 2 is isolated from the foundation 1 by a rolling bearing 3. A vibration control device 6 with a releasable rigid connector 5 is added in parallel to the rolling bearing 3. Further, a release controller 8 of the rigid connector 5 is connected to the output end of an earthquake detector 7 on the house 2, so as to release the rigid connector 5 in response to output signal from the earthquake detector 7. Thus, the building 2 normally stands without vibration against wind by rigid connection to the foundation 1 through the rigid connector 5. On the other hand, when earthquake occurs, the rigid connector 5 is released by the release controller 8 by the output from the earthquake detector 7, so as to control the vibration of the building 2 by a combination of the rolling bearing 3 and the vibration control device 6.
