| Number | Title | Issue Date |
| 6998689 | Fluid delivery for scanning probe microscopy The following invention pertains to the introduction of a gas (or fluid) around a SPM probe or nanotool™ to control chemical activity e.g. oxygen to promote oxidation, argon to inhibit oxidation or clean dry air (CDA) to inhibit moisture to control static charging... | 02/14/2006 |
| 6928894 | Compensated actuator with optimized power An actuator combining mechanical and hydraulic forces includes a cylindrical body and a piston that can slide relative to the cylindrical body. The piston and the cylindrical body are connected by a mechanical system for transmitting mechanical power that constitute... | 08/16/2005 |
| 6817260 | Ball screw with cooling means The cooling means for the present invention is formed in the screw nut instead of forming in the screw bolt. A cavity is formed between an outer cover and the screw nut as a pathway for cooling agent so as to deprive the screw nut of generated heat therein. To assur... | 11/16/2004 |
| 5816104 | Hydrostatic feed screw mechanism and movable body using the same A feed screw mechanism includes a nut having a female thread, and a feed screw shaft having a male thread screw-engaged with the female thread. A thrust pocket is formed along a flank of the female thread of the nut, and pressurized fluid is supplied ther... | 10/06/1998 |
| 5511438 | Positioner A positioner includes a pressurizer for pressurizing an interface between a feed screw and a feed nut, and a pressure control unit for controlling pressurization so that the extent of pressurization is set to a desired value. When a backlash due to abrasi... | 04/30/1996 |
| 5090265 | System to convert rotary motion to linear motion In a system that includes a linearly movable carriage or the like, a mechanism to convert rotary motion of a leadscrew to linear motion of a nut and, hence, linear movement of the carriage to which the nut is mechanically secured. The leadscrew has a spec... | 02/25/1992 |
| 4836042 | System to convert rotary motion to linear motion In a system that includes a linearly movable carriage or the like, a mechanism to convert rotary motion of a leadscrew to linear motion of a nut and, hence, linear movement of the carriage to which the nut is mechanically secured. The leadscrew has a spec... | 06/06/1989 |
| 4793201 | Porous static pressure guide A static pressure lead screw includes a porous ceramic body having fluid flow paths as part of a flank. The porous ceramic body is fixed by a tubular base member through which the fluid does not flow. Fluid guide holes for supplying the fluid to the porou... | 12/27/1988 |
| 4776229 | Device for controlling the rectilinear translation of a movable member A device for controlling the rectilinear translation of a movable member, comprises a screw engaged by a nut having cooperatingly shaped thread surfaces the dimensions of which are such that there is a radial clearance between the screw and the nut and an... | 10/11/1988 |
| 4586394 | Low noise lead screw positioner A lead screw positioner (10) is described, which has extremely low noise, including a nut (12) lying about a lead screw (14) and means for flowing gas under pressure between the nut and screw to keep them slightly spaced. The nut forms a plenum chamber (3... | 05/06/1986 |
| 4232562 | Lead screw linear actuator A linear actuator which can apply high forces is described, which includes a reciprocating rod having a threaded portion engaged by a nut that is directly coupled to the rotor of an electric motor. The nut is connected to the rotor in a manner that minimi... | 11/11/1980 |
