Title: Ignition control device of internal combustion engine
Inventor: MOGI KAZUHISA
IPC: F02P3/045
Filed: 1999-05-26
Abstract: PROBLEM TO BE SOLVED: To avoid increase of torque fluctuation caused by delay of ignition timing after the second time in a high speed rotating region on an internal combustion engine to carry out multiple ignition. SOLUTION: It is necessary to prevent delay of ignition timing after the second time by shortening total time of discharge time td in which an ignition signal is maintained off and downtime tw in which the ignition signal is maintained on again in a high speed rotating region. As combustion also becomes fast when rotating speed is increased, it is possible to always maintain constant ignitability by shortening the discharge time td. Thereby, the discharge time td is set short when rotating speed is high. As energy remains in an ignition coil in the case when it is electrified at an early stage in the middle of discharging by shortening the discharge time td, it is possible to secure desired energy even when the downtime tw which is charging time to the primary side of the ignition coil. Consequently, the downtime tw is also set short at the time of high speed rotation.

Filed: 1988-06-15
Abstract: PURPOSE:To eliminate the need for providing paper and lens channels in a simulator system and to simplify circuit configuration by adjusting the three- color component of printing light illuminating a color negative image. CONSTITUTION:A photographic printer observes a color monitor 34 in order to decide whether or not a printed picture is finished appropriately. When its color or density is inappropriate, a corrected amount is inputted by operating the color key 43 or density key 44 of a photographic printing system. When the corrected amount is inputted, a CPU 51 calculates again an expression 2 for calculating the amount of exposure. Based on the obtained amount of exposure for monitoring, the setting positions of color filters 16-18 are adjusted. Since the illuminating condition of a frame varies according to the corrected amount which is manually inputted, a simulator image wherein color or density is corrected is displayed on the color monitor 34.
