Title: Graphic processor
Inventor: KITAJIMA FUMIHIDE
IPC: G06F3/048
Filed: 1989-12-29
Abstract: PURPOSE:To recognize whether a graphic to be selected is in a state where it can be selected in a device or not by moving a cursor by means of moving a pointing device and displaying the graphic displayed in a position nearest to the cursor in a display form different from the other graphic. CONSTITUTION:A pointing device control part 33 counts the number of pulses following the movement of the pointing device 34, decides information on coordi nate data and the depression of the key of the pointing device 34 and outputs it as even information from the pointing device 34. In such a case, instruction marks for selection candidates 16 are displayed in both ends of a segment graphic 13 positioned in a distance near the cursor 12. When the moves and the cursor 12 comes to the distance near to a circle much more than the seg ment graphic, the instruction marks on the segment graphic are eliminated and the instruction marks of selection candidates are displayed on the periphery of the circle. Thus, it can easily and visually be recognized which graphic comes to the candidate of selection before the selection of the graphic is decided.

From a map data M1 air excess rate λi is calculated from the EGR rate αi on the basis of the relation of the EGR rate αi corresponding to the engine speed Ne and load quantity LOAD with the air excess rate λi. The air excess rate λi is compared with a judgment value λc, and in case of λi<λc, the fuel injection quantity is reduced with respect to only the cylinder having an air excess rate λi lower than the judgment value λc. According to this, the increase in black smoke exhausted from the engine is suppressed.
