20080233385 | Papers Providing Great Fat and Oil Penetration Resistance, and Method for the Production Thereof - Different papers known in prior art develop only moderate resistance to fats or contain fluorocarbon compounds or chromium complexes in the mass or in an impregnating liquor in order to develop great fat and oil penetration resistance. Said fluoride or chromium compounds represent substances that are known to be or at least seriously suspected of being unhealthy. Hence, the aim of the invention is to create a paper that is free from unhealthy components while being provided with great fat and oil penetration resistance, being easy to print, and being recyclable. Said aim is achieved by obtaining great fat and oil penetration resistance by using a paper that is made of thoroughly ground fiber materials and is glued with alkenyl succinic anhydride in the mass during impregnation inside or outside the papermaking machine with an impregnating liquor containing polyvinyl alcohols, ethylene-vinyl alcohol copolymers, polyvinyl butyrals, carboxymethylcellulose, gelatin, alginates, galactoglucomannans, and/or starch derivatives, polyvinyl alcohol and gelatine being preferred. | 09-25-2008 |

20090140587 | Spindle motor having a fluid dynamic bearing system and a stationary shaft - The invention relates to a spindle motor having a fluid dynamic bearing system comprising axial and radial bearings that contains a rotor component ( | 06-04-2009 |
20100124387 | Fluid dynamic bearing system - The fluid dynamic bearing system has at least one stationary part, and at least one rotating part that is supported rotatable about a rotational axis with respect to the stationary part. A bearing gap filled with bearing fluid is formed between mutually opposing surfaces of the stationary and of the rotating part. The bearing system comprises at least one fluid dynamic radial bearing and at least one fluid dynamic axial bearing that are disposed along sections of the bearing gap. Moreover, sealing means for sealing the open ends of the bearing gap are provided. According to the invention, one of the sealing means comprises an annular sealing gap that has one end connected to the bearing gap and one end connected to an annular reservoir, the outside radius of the reservoir measured from the rotational axis being larger than the outside radius of the sealing gap. | 05-20-2010 |
20140049856 | SPINDLE MOTOR HAVING A LOW OVERALL HEIGHT - The invention relates to a spindle motor that comprises a stationary motor component having a shaft and an annular stopper part disposed at a free end of the shaft as well as a rotatable motor component that is rotatably supported by means of a fluid dynamic bearing system with respect to the stationary motor component. The rotatable motor component is driven by an electromagnetic drive system. A housing cover covers the spindle motor. The invention is characterized in that the shaft has a step on which a stopper part rests, the end face of the stopper part projecting axially beyond the end face of the shaft, and the housing cover resting only on the end face of the stopper part but not on the end face of the shaft. | 02-20-2014 |
20140093197 | FLUID DYNAMIC BEARING SYSTEM - The fluid dynamic bearing system has at, least one stationary part, and at least one rotating part that is supported rotatable about a rotational axis with respect to the stationary part. A bearing gap filled with bearing fluid is formed between mutually opposing surfaces of the stationary and of the rotating part. The bearing system includes at least one fluid dynamic radial bearing and at least one fluid dynamic axial bearing that are disposed along sections of the bearing gap. In one aspect of the invention, an annular sealing gap for sealing open ends of the bearing gap has one end connected to the bearing gap and one end connected to an annular reservoir, the outside radius of the reservoir measured from the rotational axis being larger than the outside radius of the sealing gap. | 04-03-2014 |
