Abstract: In an ion implantation apparatus, a reduction of an energy contanimination is achieved when ions are implanted into a wafer with a low energy. A beam transportation efficiency between mutually different positions on a beam line correlates with the energy contamination of the wafer, and the beam transportation efficiency is adjusted so that the energy contamination becomes small. Since the beam transportation efficiency is obtained by measuring a beam electric current at each position, the beam transportation efficiency can be obtained before the ions are implanted into the wafer.

Abstract: In a color separator circuit, edge detection filters detect an edge encountered in the horizontal direction. When the image signals corresponding to the thus detected edge are processed, selector circuits 12a to 12c select outputs from small-tap-number color separation filters 8a to 8c and 10a to 10c, respectively. When the image signals corresponding to the remaining portion other than the edge are processed, the selector circuits 12a to 12c select outputs from large-tap-number color separation filters 9a to 9c and 11a to 11c, respectively. A ratio calculator circuit 16 calculates, from the luminance signals fed from adder circuits 13a to 13c, the value by which a multiplier circuit 18 performs multiplication. The multiplier circuit 18 multiplies, by this value calculated by the ratio calculator circuit 16, the color separation signals added together by an adder circuit 17 so that, of all the color separation signals of which there are two kinds, those of one kind are vertically interpolated.

Abstract: A processing apparatus capable of grinding an arcuate groove (a groove having an arcuate shape in section) of various shapes defined in a work with a good accuracy. A pseudo-elliptic arcuate groove defined in a work is ground by a forming grindstone. The work is moved in a Y-axis direction (vertically on a paper sheet) in a state in which the forming grindstone is supported on a tool table for rotation and is moved in a X-axis direction (a direction perpendicular to the paper sheet) to abut against the arcuate groove, while rotating the work in a direction of an arrow with its axis L matched with an axis C of an indexer. Thus, it is possible to relatively move the forming grindstone to trace the arcuate groove, thereby accurately grinding the arcuate groove.

Abstract: A rectifying section 2, and a DCDC converter 3 which lowers an input DC voltage and then outputs the voltage are disposed between an AC generator 1 and a load 4. When the output voltage Vt of the AC generator 1 is gradually lowered with starting from E0, the output power P is increased, and is maximum at Vt=V12. When the output voltage Vt is further lowered, the output power P is reduced. As an operating point at which the same output power P is obtained, there are a point of Vt=V11, and that of Vt=V13. The operation of the DCDC converter 3 is controlled so as to operate at the point of Vt=V13 where the output current I is lower.
