Abstract: A method and apparatus for representing a processed workpiece in perspective with invisible covered edges on the picture screen of a numerically controlled machine tool includes the steps of resolving both the workpiece and the tool into equidistant sections and storing the coordinates of these sections in a RAM. In correspondence to the relative movements of the tool and workpiece determined by the numerical control program, the associated sections of the tool and workpiece are superimposed in an image point memory. With the aid of a simple algorithm the section contour of the workpiece is altered by the superposition is determined, and its coordinates are stored in the RAM. After this process has been completed for all section planes, all sections are successively fed into the image point memory, with succeeding sections offset by several image points in the X and Z directions with respect to the preceding sections. After each superposition, the algorithm is used to determine the resulting outer contour, which is applied to the display. Covered parts of sections lying in the background are not represented on the display, since they lie inside the outer contour determined up to that time.

Abstract: PROBLEM TO BE SOLVED: To provide a control device for a four wheel drive vehicle, which can obtain a sufficient uphill road running capacity, and concurrently, can avoid the use of unnecessary aiding drive. SOLUTION: Since the output of a MG 28 is controlled by a motor driving control means (secondary prime mover control means) 70 based on such a vehicle speed condition as the driving force of the secondary prime mover (MG) 28 is reduced by a traction control means 60, a sufficient uphill road running capacity can be obtained, and the use of unnecessary aiding drive can be avoided.  Namely, regardless of the rotating speed of each front wheel 20 being in a range of a specified width of change with respect to the rotating speed of each rear wheel 34, for example, unless a vehicle speed V is enough to be in a condition (V>=Vx2) capable of running ahead, the output torque of the MG 28 can be maintained so as to allow sufficient driving force to be obtained when a vehicle runs over an uphill road having a low μ, and meanwhile, when the vehicle speed V is in a condition capable of running ahead, the output torque of the MG 28 can be lowered, the use of unnecessary aiding drive is avoided, and energy can thereby be prevented from being fruitlessly consumed.

Abstract: An apparatus for sharpening knives, and the like where fixed abrasive elements on an orbiting surface in contact with the knife cutting edge facet move in a mechanically generated uniform cyclic orbit of circumference less than about one (1) inch and through that motion provides the work and energy to sharpen the knife or blade edge. The apparatus provides a circumferential velocity of the abrasive element of less than 800 feet per minute and restrains motion of the abrasive surface to less than ± .005 inch in a direction perpendicularto the intended plane of the knife or knife edge facet. The apparatus contains novel magnetic and other means to steady, guide and control position and angle of the face of the blade relative to the orbiting abrasive elements, to realign any burr or sharpening debris on the knife edge, to control in part the abrading forces, and to remove sharpening debris from the abrasive surface and sharpening zone. A means used to create the orbital motion of the abrasive surface utilizes a pair of synchronously driven eccentric cranks that engage an orbiting drive plate that supports the abrasive surface or surfaces, where the eccentric cranks are mounted on or are an integral part of the shafts of two gear pulleys driven syncronously by means of a motor-driven timing belt, and where the supporting drive plate is constrained to orbit in a prescribed principal plane by means of fixed bearing support points.
