20080309183 | Dynamic Bearing Device - Disclosed is a dynamic bearing device which allows production of a smaller housing at low cost and which suppresses ion elution from the resin portion to thereby maintain cleanliness in the dynamic bearing device and exert a desired bearing performance. A dynamic bearing device | 12-18-2008 |
20090022439 | FLUID DYNAMIC BEARING DEVICE - A fluid dynamic bearing device having high bearing performance at low cost is provided. | 01-22-2009 |
20090046960 | FLUID DYNAMIC BEARING DEVICE - A fluid dynamic bearing device which can exhibit high bearing performance is provided at low costs by forming a highly accurate bearing gap. | 02-19-2009 |
20090092347 | FLUID DYNAMIC BEARING DEVICE - A fluid dynamic bearing device capable of exercising high bearing performance is provided at low cost. | 04-09-2009 |
20090110339 | Bearing Device with Sliding Bearing - A sliding bearing according to the present invention includes a metal part formed by electroforming on an inner periphery of the sliding bearing and an oil feeding mechanism for supplying oil to the bearing gap. As a result, oil retained by the oil feeding mechanism is supplied to the bearing gap, so the lubricity between the bearing and the shaft member is improved by an oil film formed in the bearing gap, making it possible to avoid generation of noise due to defective lubrication and wear of members due to the contact sliding between the bearing and the shaft member. | 04-30-2009 |
20090230593 | METHOD FOR FORMING DYNAMIC PRESSURE GENERATING GROOVES - High-precision, low-cost molding of dynamic pressure generating grooves is made possible. | 09-17-2009 |
20090232430 | FLUID DYNAMIC BEARING DEVICE AND METHOD OF MANUFACTURING THE SAME - In this type of fluid dynamic bearing device, there is formed a resin member capable of suppressing the intrusion of a lubricating oil as much as possible even when carbon fibers are compounded. | 09-17-2009 |
20090284866 | FLUID BEARING DEVICE, METHOD OF MANUFACTURING THE SAME, AND DISK DRIVE DEVICE - Provided is a fluid bearing device with a hub part having high molding precision and dimensional stability and capable of being produced at low cost. An annular gate ( | 11-19-2009 |
20090297076 | FLUID DYNAMIC BEARING DEVICE - A hub portion of a fluid dynamic bearing device is formed from a resin composition in which polyphenylene sulfide (PPS) is employed as a base resin and with which carbon fibers are mixed. In this manner, the wear resistance and the conductivity can be improved. Alternatively, both portions of a stationary body and a rotating body of the fluid dynamic bearing device which portions face to each other through a bearing gap are formed from a resin composition in which polyphenylene sulfide (PPS) is employed as the base resin. In this manner, excellent wear resistance can be obtained. | 12-03-2009 |
