Title: Exhaust gas purifying device for internal combustion engine
Inventor: NAKAMURA KANEHITO
IPC: F01N3/08
Filed: 1997-03-18
Abstract: PROBLEM TO BE SOLVED: To properly control an HC feeding amount to a catalyst or a catalyst temperature by estimating the NOx purifying state of a NOx catalyst with high precision. SOLUTION: NOx sensors are arranged at the vicinity of the central part of a NOx catalyst and the outlet thereof respectively. Based on the outputs of an accelerator sensor and the number of revolutions of engine sensor, NOx concentration S1 and a NOx amount of catalyst-contained gas are calculated (steps 101 and 102). From the outputs S2 and S3 of two NOx sensors and NOx concentration S1 of catalyst-contained gas, a NOx concentration changes (S2-S3) of a downstream part of the internal part of a catalyst are calculated (step 104). From the calculated value, a catalyst activated state is estimated (step 105). As a result, when the present catalyst activated state is judged on the low temperature side of a NOx purifying temperature window, calculation of an HC reference feed amount and the catalyst heating are carried out (step 106).  When the present catalyst activated state is judged on the high temperature side of the NOx purifying temperature window, calculation of the HC reference feed amount and the catalyst cooling are carried out (step 107).

Filed: 1986-03-25
Abstract: PURPOSE:To correct the wrinkle or curvature of paper sheets and the like by pressing the paper sheets with a pressing means when it is detected that the quantity of the remaining paper sheets becomes small while correcting the wrinkle or curvature by the own weight of paper sheets when the remaining quantity of said paper sheets is large. CONSTITUTION:When a start switch is operated, a take-in roller 50 is rotated to take in paper sheets from a feeding part and a JK-FF circuit 82 is set while resetting an RS-FF circuit 84. At this time, the output signals of AND circuits 86, 89 are at low levels, without driving a motor 56. Accordingly, when the quantity of paper sheets placed on the feeding part is large, a backup 55 is not operated and the paper sheets are taken in only by their own weight. On the other hand, when the quantity of the paper sheets is reduced and a remaining quantity detecting switch 67 is turned on, a high level signal is outputted from the AND circuit 86. Thereby, the motor 56 is outputted from the AND circuit 86. Thereby, the motor 56 is driven and the backup 55 is lowered, to pressingly take in the sheets of paper.
