Title: Formation of color image
Inventor: KODERA HIROTERU
IPC: G03G13/01
Filed: 1983-09-01
Abstract: PURPOSE:To enhance color reproducibility by incorporating complementary color filter particles having subtractive action in addition to particles having a filter action of additive color mixture in accordance with a correction amt. to execute subtractive action on the complementary color light. CONSTITUTION:R particles 403 contg. dispersed conventional C dye, G particles 404 contg. conventional dispersed M dye, and B particles 401 obtained by dispersing Y-colored sublimable dye into a B pigment lose attaching force when they are exposed to each of R, G, and B colored lights, respectively, but since the M particles 402 for correcting red obtained by likewise dispersing a sublimable Y-colored dye into an M pigment executes filter action, the Y dye contained in these particles is removed by the R-colored light in addition to the intrinsic R-colored light in an exposure development processes from the relationship: M-colored light = R-colored light + B-colored light. Therefore, the M particles 402 in addition to the R particles 403 are freed of attaching force by the R-colored light, and since the Y dye is subtracted by the amt. of the M particles 402, a corrected red color high in saturation can be reproduced by causing this subtracting amt. to correspond to a set calculation equation.

Abstract: PURPOSE:To recognize the position of components in specific position relation by irradiating one large plane of a component which has an uneven surface with a light beam from a parallel finite observation surface, and recognizing positions of the uneven surface characteristic to the component surface. CONSTITUTION:When a semiconductor chip component 5 is irradiated with the light beam from the observation surface 6, the route 9 of a light beam which is reflected by a plane parallel to the observation surface is the same. The route 11 of a light reflected by a slanting part forming a recessed surface part 10 never returns to the observation surface. This is cut on the basis of a specific threshold value and then an area showing a plane part parallel to the observation surface is formed on the observation surface. An area 12 showing a recessed surface part 10 in specific position relation of the radiation direction with a light emission source is similar to a previously given area, etc., sandwiched between two areas showing other planes, and smaller in area than the two areas, so that it is selected from all areas. The, the axis where the rotary moment of the area 12 is minimum is calculated and the radiation direction of a laser beam 7 and the position of the light emission source 8 are known from the position and direction of the axis.

Abstract: PURPOSE:To cut a recording medium where a multicolor image is recorded at a specific position without causing any shift by detecting the shift between a conveyor roller and the recording medium with a register mark and correcting the cutting position. CONSTITUTION:The shift at the time of next image recording is detected and corrected to cut the medium between a last image and a following image. For example, if a difference of (m) pulses is generated between a reference register mark read (a) in the 1st pass of the next image and a reference register mark read (b) in the final pass (4th pass) of the next image, a slip of (m) pulses is generated between the conveyor roller 8 and recording paper 1. Then a pulse motor is driven by (n+m) pulses as the sum of the number (n) of pulses up to an indicated cutting position and a correction number (m) for the shift and then the medium is cut, so that the medium is cut at the correct position where the shift is corrected.
