The purification control device (12) sets a pre-deterioration maximum occlusion amount based on the SCR catalyst temperature, and estimates the concentration of ammonia discharged from the SCR catalyst (4), as an estimated ammonia concentration, based on upstream NOx concentration information, downstream NOx concentration information, urea injection amount information, the pre-deterioration maximum occlusion amount, and ammonia occlusion amount information. The purification control device (12) acquires downstream ammonia concentration information. When the downstream ammonia concentration is greater than the estimated ammonia concentration, the purification control device (12) decreases the supply amount of urea from the urea water injector (5).

Abstract: In a coordinate correction apparatus, a coordinate acquisition unit sequentially acquires coordinates of touch positions on a touch panel when a touch operation is continued on the touch panel. When the coordinate acquisition unit acquires first coordinates which are coordinates of a new touch position, a coordinate correction unit calculates a weighted average of the first coordinates and second coordinates determined from coordinates of a past touch position acquired by the coordinate acquisition unit, with applying weighting that varies according to a touch movement amount on the touch panel. The coordinate correction unit outputs a calculation result as corrected coordinates. An application unit uses the corrected coordinates.
