Title: Color image processing method, color image processing apparatus, program, and recording medium
Inventor: IMAI HARUYUKI
IPC: G06T1/00
Filed: 2001-03-28
Abstract: PROBLEM TO BE SOLVED: To solve an inconvenience in which an image is not displayed or printed in colors desired by a user since a delicate difference is excessively captured because an original image to be read has so many color gradation levels, or a color which is actually not required is captured influenced by lighting at the time of photographing of an original image or the like. SOLUTION: An XYX value and an xyY value are calculated from an RGB value of image data (S10, S20). It is determined to which color area of black, blue, red, yellow, and white the xyY value belongs (S30-S60). The RGB value is converted to an RGB value of a color corresponding to a color area to which xyY value belongs. Specifically, all RGB values belonging to a color area of predetermined color are converted to one RGB value (S70-S110). For example, an RGB value belonging to black color area is converted to a black RGB value (S70), and an RGB value belonging to white color area is converted to a white RGB value (S110).

Title: Manufacturing method of dynamo-electric machine and dynamo-electric machine
Inventor: NAKA KOKI
IPC: H02K1/16
Filed: 2001-04-26
Abstract: PROBLEM TO BE SOLVED: To provide the manufacturing method of a dynamo-electric machine and the dynamo-electric machine, with which winding operation is facilitated and harmonic magnetic flux generation caused by the opening of a slot can be reduced, without arranging magnetic wedges. SOLUTION: As shown in Fig. (a), first magnetic steel plates 13, each having a first and second projection 13c and 13d asymmetrically formed on the left and right on the extremity of a protrusion 13a, and second magnetic steel plates 14 each having a first and second projection 14c and 14d asymmetrically formed on the left and right on the extremity of a protrusion 14a, are laminated to form a slot-shape opening 16C with a width C, where windings (not shown) are wound around slot-shape parts 16b. Then, the magnetic steel plates 14 are shifted to the right, to superimpose center parts 14b on center parts 13b, as shown in Fig. 4 (b). As a result, the second projections 14d approach the first projections 13c, narrowing the width F (F<C) of a slot opening 11c, so that losses caused by slot harmonics can be reduced without arranging the magnetic wedge.  Also, at winding, winding operation is facilitated, because the width of the slot-shape opening 16c is set as wide as for C.
