摘要： Disclosed is a digitizing method of sensing an amount of displacement of each axis applied to a stylus by a tracer head, profiling a model surface while controlling the stylus in such a manner that the amount of displacement is made equal to a reference amount of displacement, sequentially fetching positional data by a predetermined method, and outputting NC data, wherein a difference between the amount of displacement and the reference amount of displacement is monitored, and the difference is added to the positional data and a specific positional data obtained when the difference exceeds a predetermined value is output. Although the amount of displacement of each axis is controlled to be equal to the reference amount of displacement when a gently inclined configuration is profiled, at the moment when a corner is reached, a phenomenon that the stylus is spaced apart from a model arises so that the difference between the amount of displacement and the reference amount of displacement is increased. This change is sensed and regarded to exhibit the corner, and thus the difference is added to the output point obtained by a usual digitizing and the positional data at a point is output.

摘要： A tracing control system machines a workpiece to a desired contour corresponding to the surface of a model which is being traced. The tracing control system comprises a tracing control circuit, a digitizing circuit, and numerical circuits. The tracing control circuit controls a plurality of tracing axes to trace the surface of the model. The digitizing circuit is connected to the tracing control circuit through a bus, for reading the positions of the tracing axes as positional data from time to time and processing the positional data to prevent a cutter head from biting into the workpiece, thereby to generate NC data linearly approximate the surface of the model. The numerical control circuits are connected to the digitizing circuit through the bus, for positionally controlling as many machining axes as the number of the tracing axes on the NC data to machine the workpiece.

摘要： A tracing control system for machining a workpiece through tracing by calculating speed command values of respective axes, using change amounts detected by a tracer head, and moving a cutter relative to the workpiece through control of the speed of the respective axes in accordance with the speed command values. The system is provided with calculating means for calculating predetermined values in proportion to amounts of change in the speed command values of the respective axes, and a U-axis motor and a W-axis motor for moving only a model in parallel with the above respective axes by amounts corresponding to the respective predetermined values. A sub-table, on which only the model is placed is provided on a main table of a tracing machine tool, is moved in the same direction as the direction of movement of the main table, by an amount proportional to the amounts of change in the speed command values, for example, the amounts of delay in the reactions of the servo systems. Thus, the tracer head always precedes the cutter. When the tracer head comes to a corner and the axis speed is reduced, the sub-table is returned by the amount corresponding to the reduction in the axis speed. This return amount corresponds to the amount of over-run of the tracer head in the axial direction. Because the amount of movement of the cutter is reduced by the over-run amount, overshot machining is prevented.

摘要： A tracing control system for machining a workpiece through tracing by calculating speed commands of respective axes, using change amounts detected by a tracer head, and by moving a cutter relative to the workpiece through a control of the speed of the respective axes in accordance with the speed commands. First delay speed commands are obtained from the speed commands (Vx, Vz) at delay circuits (14a, 14c), respectively, and second delay speed commands are obtained at second delay circuits (14b, 14d), respectively, the differences between the first delay speed commands and the above second delay speed commands are calculated, and an X-axis main motor and a Z-axis main motor are driven in accordance with the first delay speed commands, and an X-axis sub-motor and a Z-axis sub-motor are driven in accordance with the calculated differences, thereby move the tracer head. As a result, the tracer head always precedes the cutter, and when the tracer head comes to a corner and the axis speed is reduced, the precedence amount of the tracer head is canceled out (relatively returned) by the amount corresponding to the speed reduction. This return amount can be made equal to the amount of over-run of the tracer head, and therefore, the amount of movement of the cutter is reduced by this over-run amount of the tracer head, to thereby prevent overshot machining.

摘要： A trench gate type power transistor of high performance is provided. A trench gate as a gate electrode is formed in a super junction structure comprising a drain layer and an epitaxial layer. In this case, the gate electrode is formed in such a manner that an upper surface of the epitaxial layer becomes higher than that of a channel layer formed over the drain layer. Then, an insulating film is formed over each of the channel layer and the epitaxial layer and thereafter a part of the insulating film is removed to form side wall spacers over side walls of the epitaxial layer. Subsequently, with the side wall spacers as masks, a part of the channel layer and that of the drain layer are removed to form a trench for a trench gate.

摘要： A machine having X- and Y-axis linear moving axes and a pivot axis B for rotationally pivoting a pivot member having a tool arranged at a distal end thereof about an axis parallel to a Z axis is controlled. A moving command obtained by a command program commanded by a position expressed by X, Y, and Z in a three-dimensional orthogonal coordinate system is subjected to an interpolation process to calculate amounts of interpolation movement (ΔX, ΔY, and ΔZ) of the respective orthogonal axes. An amount of rotation Δθ of the pivot axis required for moving the tool by the amount of movement ΔY in the Y-axis direction is calculated. An amount of correction movement δx for canceling the movement in the X-axis direction caused by the rotation Δθ of the pivot axis B is calculated. Values (ΔX+δx), Δθ, and ΔZ are outputted to the X axis, the pivot axis B, and the Z axis, respectively.
