Abstract: PURPOSE:To enable to obtain excellent binary signal, even if no white part is present at the initial part of an original, by automatically setting a threshold voltage to a given voltage value if the threshold voltage to binarize a video signal is less than the specified value. CONSTITUTION:A video signal Sa read out from an image sensor IS is amplified A and the peak voltage of the video signal is held at a peak hold circuit PH, and a voltage Vs divided with a resistor VR is given to a comparator COMP as a reference voltage and it is compared with the signal Sa to obtain a binary signal of white and black level. If the voltage Vs is lower than the predetermined voltage value, a voltage Vf set at a minimum threshold set circuit LS is given to COMP as the reference voltage. Accordingly, even if no white part is present to a original corresponding to the initial part of the video signal read out from IS, an excellent binary signal is obtained.

Title: Exhaust emission control device for engine
Inventor: OKAMOTO KENJI
IPC: F02D41/04
Filed: 1999-03-10
Abstract: PROBLEM TO BE SOLVED: To prevent the deterioration of NOx absorption performance when an exhaust emission control device, with a lean NOx catalyst disposed in an engine exhaust passage, reduces oxygen concentration in exhaust emission as well as increases CO concentration, when NOx is emitted from the NOx catalyst for purification through reduction, and then switches again to an oxygen excess atmosphere. SOLUTION: When NOx is emitted from a lean NOx catalyst, CO concentration in exhaust emission is increased through division of fuel injection (SB6 to 9). Then, immediately before switching an engine to a stratified-charge combustion mode (SB10), air-fuel ratio in a combustion chamber is maintained in a slightly leaner condition than an ideal air-fuel ratio (SB11) to slightly increase oxygen concentration in the exhaust emission. At this time, EGR amount is corrected by supplemental increase. A three-way catalyst, in which HC removal rate is set to be higher than CO removal rate, can be disposed in an exhaust passage in the upstream of the lean NOx catalyst.
