Title: Detecting device for deterioration of catalyst in internal combustion engine
Inventor: MITSUYA NORITAKE
IPC: F01N3/20
Filed: 1995-10-30
Abstract: PROBLEM TO BE SOLVED: To accurately judge deterioration of a catalyst based on the outputs of an O2 sensor on the downstream side of the catalyst regardless of the air-fuel ratio fluctuation range of a catalyst-containing gas in an internal combustion engine which performs feedback control of the air-fuel ratio based on outputs of an A/F sensor provided on the upstream side of the catalyst. SOLUTION: When an O2 sensor output locus length LVOS or an O2 sensor-to- A/F sensor output locus length ratio LVOS/LVAF is plotted on a y-axis and an A/F sensor output locus length LVAF is plotted on an x-axis, a threshold for discriminating between a normal catalyst and deteriorated ones can be set within a specific range of the LVAF. When the locus length LVAF is within such a predetermined range, a determination process based on the locus length LVOS or the locus length ratio LVOS/LVAF is performed. Also, a deterioration criterion is varied depending on the locus length LVAF.

Filed: 1996-10-04
Abstract: PROBLEM TO BE SOLVED: To obtain the subject compound useful as intermediate for medicines by optical resolution of the racemic form of pyridazinone. SOLUTION: This optically active pyridazinone having R- or S-configuration of formula II is obtained by optical resolution of the racemic form of pyridazinone shown by formula I by the use of L- or D-tartaric acid as a resolution agent in a mixed solvent (e.g. 1-propanol/ethyl acetate). In this case, the molar ratio of the L- or D-tartaric acid to the compound of formula I is 0.3-1.8. Besides, a system containing an excess of the unnecessary compound of formula II with R- or S-configuration or its tartrate is treated with an acid or base to enable recovering the racemic form of formula I. The above method affords the objective compound of formula II in high optical purity at low cost, considerably reduces the amount of the solvent to be used, and shortens the production time for the amied compound.
