摘要： A double-sided tangential cutting insert, as well as a tool holder system that carries a plurality of the double-sided tangential cutting inserts, that has a peripheral side shape, as viewed from one of said cutting rake faces, that includes a pair of generally identical opposing main cutting edges wherein each of the main cutting edge comprises a substantially straight main cutting edge portion and an adjoining convex main cutting edge portion. The convex main cutting edge portion is truncated by an adjacent convex minor side face so as to define a generally sharp edge and a point of truncation. The peripheral side shape further includes a pair of opposing full nose cutting edges with a nose cutting radius; and a pair of opposing convex minor cutting edges with a minor cutting edge radius. The minor cutting edge radius is at least about four times greater than the nose cutting radius.

摘要： A reliable and cost-efficient direct drive force feedback motor is suitable for joystick applications, allowing multiple degrees of output freedom, requiring no coil commutation, and permitting compact packaging. A multiple degree-of-freedom motor consistent with the invention comprises an output shaft, a stator, and a rotor. The stator comprises first and second lamination stacks, each lamination stack having an interior curved surface and a coil wound thereon, the lamination stacks being disposed adjacent the output shaft. The rotor is fixed to the output shaft and movably supported adjacent the stator with an air gap disposed between the rotor and the stator, the rotor including at least one magnet disposed thereon and being movable along the interior curved surface of the lamination stacks in directions defining at least first and second degrees of freedom. Energization of the coil of the first lamination stack establishes a first magnetic field to urge the output shaft to rotate in a first plane, and energization of the coil of the second lamination stack establishes a second magnetic field to urge the output shaft to rotate in a second plane substantially orthogonal to the first plane.

摘要： Provided herein are exemplary methods for increasing crop yield. One exemplary method for increasing a yield of a crop includes controlling plant tissue stress by at least partially coating a plant tissue with a composition comprising an agricultural sunscreen formulation and a second agricultural chemical. The agricultural sunscreen formulation and the second agricultural chemical may be applied to the plant tissue from separate containers, wherein each container either contains the agricultural sunscreen formulation or the second agricultural chemical. Further, the agricultural sunscreen formulation and the second agricultural chemical may be applied to the crop at or near the same time. Alternatively, the agricultural sunscreen formulation and the second agricultural chemical may be applied to the crop from a shared container, wherein the shared container contains both the agricultural sunscreen formulation and the second agricultural chemical.
