An air-fuel ratio feedback control quantity is calculated by a control quantity calculation 5 based on the outputs of the oxygen sensors 15 and 16. The air-fuel ratio of an air-fuel mixture fed to the internal combustion engine 1 based on the air-fuel ratio feedback control quantity is feedback controlled based on the air-fuel ratio feedback control quantity by an air-fuel ratio control means 5. At that time, an air-fuel ratio just after the exhaust of the internal combustion engine 1 is estimated based on the change from the average value of the air-fuel ratio feedback control quantity by an estimating means 5 of air-fuel ratio just after exhaust. An air-fuel ratio estimated by an estimating means 5 of air-fuel ratio just before a catalyst is moderately processed to estimate the air-fuel ratio of the exhaust gas entering a catalyst converter 14. Thus, the air-fuel ratio can be accurately estimated.

Title: Liquid crystal display device and its production
Inventor: TSUDA HIDEAKI
IPC: G02F1/1337
Filed: 1999-03-19
Abstract: PROBLEM TO BE SOLVED: To decrease uneven distribution of charges in the thickness direction of a liquid crystal layer and to suppress generation of flickers by forming first and second alignment films, having different characteristics from each other in such a manner that the DC voltage remaining between the first alignment film and the second alignment film after AC voltage is applied between the first and second electrodes is smaller than the DC voltage to remain, when the characteristics of the films are made equal. SOLUTION: Uneven distribution of charges due to the difference in the width of projection patterns 17, 18 is compensated by making different film thicknesses of alignment films 28A, 28B. The alignment film formed on the substrate having a thinner projection pattern is made thin. More generally, the film thickness of the alignment films is controlled to be different from each other, in such a manner that the DC voltage remaining between the two alignment films 28A and 28B after AC voltage is applied for a specified time between a common electrode and pixel electrodes is smaller than the DC voltage would remain, if the film thickness of the alignment films is equal to each other. By this method, the generation of flickers can be suppressed. Moreover, by decreasing the uneven distribution of charges, phenomenon of baking is hardly caused.
