| 20080273263 | LUBRICATED LIMITER FOR FLUID DYNAMIC BEARING MOTOR - In one example, a FDB motor having a top-cover attached, EM biased bearing system is provided. The motor includes a shaft and rotor disposed for relative rotation, and an axial limiter for restricting axial movement of the rotor with respect to the shaft, wherein the axial limiter is wet or lubricated during contact. The limiter is spatially fixed with respect to one of the shaft or the rotor and disposed with an axial end surface opposing a surface portion spatially fixed with respect to the other of the shaft or the rotor to form a gap therebetween. The gap may be filled with a fluid such as bearing lubricant, thereby providing a lubricated or wet contact surface to restrict axial movement of the shaft and rotor. Additionally, one or both surfaces may include a groove or slot to provide circulation of fluid through the gap. | 11-06-2008 |
| 20090079283 | Fluid dynamic bearing motor with a lubricated contact surface - A fluid dynamic bearing motor is provided having relatively rotatable facing surfaces that are reliably lubricated. A radial gap is defined between the relatively rotatable facing surfaces, wherein a first axial end of a fluid dynamic bearing has a larger radial gap as compared to a central region of the fluid dynamic bearing. In an aspect, a fluid recirculation passageway is established between the first axial end and the central region of the fluid dynamic bearing. In an aspect, a fluid reservoir is formed axially above the first axial end of the fluid dynamic bearing. Robustness of the FDB motor is increased, and sensitivity to external loads or mechanical shock events is reduced. Dry surface-to-surface contact of bearing surfaces and reduced performance or failure of the motor or disc drive components is averted. The use of diamond-like coating on relatively rotatable fluid bearing surfaces may also be reduced or eliminated. | 03-26-2009 |
| 20100053807 | LUBRICATED LIMITER FOR FLUID DYNAMIC BEARING MOTOR - A component for restricting relative movement of a rotor and a shaft is disclosed. A motor may include a shaft and a rotor, where the rotor is disposed for relative rotation with respect to said shaft. A component is operable to restrict relative movement of the rotor and the shaft, where the component includes a first surface operable to receive a fluid. | 03-04-2010 |

| 20090142009 | FLUID DYNAMIC BEARING SYSTEM - Fluid dynamic bearing systems produced by specified methods are provided. In one example, a method for designing a fluid dynamic bearing system includes determining a first stability ratio for a first journal bearing configuration. The method further includes determining a second stability ratio for a second journal bearing configuration. In a further example system, the first configuration has two sub-journal bearings and the second configuration has three sub-journal bearings. The method may comprise comparing the two stability ratios to determine whether adding a sub-journal increases the stability ratio of the bearing system. | 06-04-2009 |
| 20100141071 | MOTOR ASSEMBLY WITH MULTIFUNCTIONAL COMPONENTS - Multifunctional components enable the construction of economical motor assemblies. A first embodiment of the present invention provides a hub, cup, spindle, and base assembly for a motor assembly having at least one journal bearing, at least one thrust bearing, and at least one fluid seal. A second embodiment of the present invention provides a hub, spindle, and base with integrated cup assembly for a disc drive bearing having at least one journal bearing, at least one thrust bearing, and at least one fluid seal. In a third embodiment, a hub is rotatably assembled with a spindle coupled to a thrust bearing, prior to assembly with a base. In further embodiments, motor assemblies comprise the above embodiments combined with stator and rotor assemblies. | 06-10-2010 |

| 20110064527 | CELLULAR SHEET PILE RETAINING SYSTEMS WITH UNCONNECTED TAIL WALLS, AND ASSOCIATED METHODS OF USE - Embodiments of the disclosure are directed to cellular sheet pile retaining wall systems with unconnected tail walls, and associated methods of use and manufacture. In one embodiment, a retaining system includes a face wall having a plurality of interconnected face wall sheet piles. The individual face wall sheet piles have a first length and extend a first depth into soil, and the face wall sheet piles form an exterior surface facing an exterior environment. The system also includes a tail wall including a plurality of interconnected tail wall sheet piles extending from the face wall away from the exterior environment. The individual tail wall sheet piles have a second length greater than the first length, and the individual tail sheet wall piles extend a second depth into the soil that is greater than the first depth. | 03-17-2011 |

| 20090232607 | EARTH RETAINING SYSTEM SUCH AS A SHEET PILE WALL WITH INTEGRAL SOIL ANCHORS - A soil raining system combining flat sheet pile wails in an open cell configuration includes integral soil anchors providing an improved earth retaining system. Another aspect of the invention is a method of designing and installing a soil retaining system with an open sheet pile cell structure having integral soil anchors. The method includes, inter alia, calculating soil forces by taking into account material strength of sheet pile, soil friction against the sheet pile in combination with the strength of the integral soil anchor, selecting sheet pile size and length based on soil forces calculation; and installation of sheet pile to form a soil retaining system. The integral soil anchors serve to provide higher load resistance to the improved earth retaining system. | 09-17-2009 |
