摘要： A suitable the inner point is set on a vapor-liquid face of lubricating fluid formed in a composite capillary seal section that utilizes capillary force and rotational centrifugal force acted on the lubricating fluid. An inner peripheral surface of a ring-shaped portion is formed such that the minimum value R 1 in radial-direction distances of the inner peripheral face of the ring-shaped portion becomes greater than a radial-direction distance R 2 of the inner point (R 1 >R 2 ). This can observe the inner point of the lubricating fluid from the immediately-above position, whereby the filling amount of the lubricating fluid can easily and surely be measured, thereby being capable of adjusting the filling amount of the lubricating fluid to a preset amount.

摘要： PROBLEM TO BE SOLVED: To reduce a cost by decreasing a number of part items and simplifying assembly man-hours, prevent oil from leaking out, and prevent adverse effects on bearing performance at a low cost in the case of fixing a bearing main unit to a housing. SOLUTION: A housing 6 is formed into a bottomed cylindrical shape, and a bearing main unit 7 is fixedly bonded to the internal peripheral surface of the housing 6. Fitting between the external peripheral surface of the bearing main unit 7 and the internal peripheral surface of the housing 6 is a clearance fit, and to this fitting space, the external peripheral surface of the bearing unit 7 and the internal peripheral surface of the housing 6 are bonded. An adhesive is supplied from the opening side of the housing 6 while sucking a space 22 between a bottom part 6a of the housing 6 and an end face 7b of the bearing main unit 7 facing opposite this bottom part, in this way, the adhesive is made to extend over almost the whole region of the fitting space.

摘要： PROBLEM TO BE SOLVED: To realize a stopper structure suitable for a thin type motor in a spindle motor, having a single surface facing type thrust bearing. SOLUTION: This spindle motor 1 is used for a recording disc drive device, and comprises a base plate 9, a hub 10 into a substantially cylindrical shape, a rotor magnet 7 and a stator 6. The base plate 9 has a flat surface. One end surface of the hub 10 in the substantially cylindrical shape faces the flat surface of the base plate 9 in the axial direction and is freely and relatively rotated with each other. The rotor magnet 7 is stuck on the hub 10. The stator 6 is disposed at the base plate 9 so as to face the rotor magnet 7. A pair of hooks 33, 62, which are engaged with each other by respective elastic deformation are provided at one end surface of the hub 10 and the flat surface of the base plate 9, and the stopper structure 17 is constituted which restrains the hub 10 from traveling to the base plate 9 in the axial direction by the pair of the hooks 33, 62.

摘要：本発明は電子を放出する電子源（５）、及び電子の入射によりＸ線を生成する材料（９）を有するキャリア（７）を含むＸ線生成装置（１９）に関する。本装置はキャリアを回転軸（１５）に対して回転させる内部軸受部材（２３）及び外部軸受部材（２１）を有する動的溝軸受（１７）を有する。この軸受部材のうちの第１軸受部（２１）はキャリアに接続する。内部軸受部材と外部軸受部材との間には液体滑剤を収容する軸受ギャップ（５７，５９，６１）が存在する。この軸受部材は熱転送経路の一部を形成し、本装置の動作中に電子がＸ線生成材料に衝突する結果発生する熱はこの熱転送経路を介してキャリアから装置の周囲に伝導される。この熱転送経路における熱転送速度を向上させるために、キャリア（７）及び第１軸受部（２１）の少なくとも一部（３３，３７）は本装置の一体構成部を形成し、同一部は少なくとも部分的に軸受ギャップ（５７，５９，６１）を覆う。好ましくは、同キャリアと第１軸受部材の一部は１つの材料から製造される。これにより、熱転送経路は、キャリアと軸受ギャップにおける第１軸受部材の一部によって覆われた部分との間においては材料分離を含まない。

摘要： PROBLEM TO BE SOLVED: To secure the life of lubricating fluid DF in a dynamic pressure bearing device provided with a composite fluid seal part CS. SOLUTION: A liquid level measuring position P is properly set in a gas-liquid interface DFs of the lubricating fluid DF positioned inside the composite fluid seal part SC using capillary force and rotational centrifugal force added to the lubricating fluid DF. An outside inclination wall surface CSo is composed in such a way that the minimum value R1 of the radial distance of the outside inclination wall surface CSo at the composite fluid seal part is larger than the radial distance R2 of the liquid level measuring position P (R1>R2). The liquid level measuring position P in the gas-liquid interface DFs of the lubricating fluid DF can thus be observed from directly above it. Charging quantity of the lubricating fluid DF can be easily and securely measured to adjust charging quantity of the lubricating fluid DF to preset quantity. COPYRIGHT: (C)2005,JPO&NCIPI

摘要： PURPOSE:To prevent the occurrance of headcrush and thereby to revolute the disc with high precision by providing a magnetic fluid sealing device to the bearing of a spindle. CONSTITUTION:When stationary, a shaft 3 is in contact with a bearing 5 and a cylindrical coil 5. When the revolution becomes higher than a certain rate, the oil between a shaft 3 and a bearing 5 maintains a regular interval between them. Because the fluid 11 has a magnetic property, it places itself between the shaft 3 and yokes 9-1, and 9-2 which are also magnetic, and further the fluid 11 exists in the magnetic circuit between the shaft 3 and the yokes 9-1 and 9-2 according to the revolution of the shaft 3, and seals hermetically the shaft 3 and the yokes 9-1 and 9-2. In result, the oil basin 12 provided in the internal surface in the center part of the bearing 5 and a hub 1 are sealed with an addhesive that is also used for sealings of a holder 8, yokes 9-1 and 9-2, a magnet 10, the magnetic fluid 11, and the shaft 3 respectively and in between.
