Title: METHOD OF CONTROLLING CATALYST ACTIVITY OF NOx OCCLUSION CATALYST
Inventor: WINKLER KLAUS
IPC: B01D53/94
Filed: 2000-05-16
Abstract: PROBLEM TO BE SOLVED: To control the catalyst activity of NOx-occlusion catalyst by measuring the NOx-concentration in combustion gas during the regeneration period by a gas sensor for sensing NOx, which is installed in the rear of the NOx-occlusion catalyst, and taking the measured NOx-concentration into consideration as a barometer of catalyst activity of the NOx-occlusion catalyst. SOLUTION: Exhaust gas of an internal combustion engine supplied by an exhaust gas passage 11 reaches the inside of an NOx-occlusion catalyst 12. While combustion mixture exists due to lean state, nitrogen oxide existing in the exhaust gas is occluded and made react with a reducing compound such as hydrogen, hydrocarbon and carbon monoxide of a combustion mixture due to rich state by catalyst during the subsequent regeneration period.  A gas sensor 14 for sensing NOx is used for measuring the NOx- concentration of exhaust gas after separation from the NOx-occlusion catalyst 12 during the regeneration period, and the shortage of catalyst activity is confirmed in the case where the absolute value of maximum value of NOx-concentration exceeds a designated value, in the case where the up gradient of NOx-concentration is below the designated vale, and further in the case where the integrated value of all NOx- concentration exceeds the designated value.

Title: Skew correcting device
Inventor: HIROSE HIROYA
IPC: B65H9/00
Filed: 2000-06-22
Abstract: PROBLEM TO BE SOLVED: To provide a skew correcting device capable of correcting skewing in a simple structure without generating trouble such as wrinkle on a recording medium. SOLUTION: When the recording medium 28 is fed normally without skewing, four helical extension springs 76, 78, 80, and 82 pull a shaft 62 uniformly, and the shaft 62 is orthogonal to an arrow B. However, when the recording medium 28 skews, load rollers 70 and 72 press a surface of the recording medium 28, so that the shaft 62 tilts together with the load rollers 70 and 72. In this case, for example, the helical extension springs 76 and 82 stretch and the helical extension springs 78 and 80 shrink. The stretching helical extension springs 76 and 82 are apt to shrink, and the shrinking helical extension springs 78 and 80 are apt to stretch. Such stretching force causes the shaft 62 to move orthogonally to the arrow B direction.
