    摘要: If the output of an O2 sensor located downstream of a catalyst deviates from a predetermined range, the air-to-fuel ratio upstream of the catalyst is over-corrected to be a leaner value or a richer value beyond the predetermined purification-efficiency range when the output of the O2 sensor downstream of the catalyst indicates rich or lean, respectively, so that the output of the O sensor downstream of the catalyst returns within a predetermined range as soon as possible.

    摘要: Provided is a control device for an engine which is capable of purifying NOx with high efficiency at a restart after an idle stop without deteriorating purification efficiency of HC and CO. At the restart after the idle stop, an air-fuel ratio is controlled to be rich, and an atmosphere inside of a catalyst is estimated on the basis of a required time ΔT from a time point at which an output value (VO2—2) of first oxygen concentration detection means upstream of the catalyst exceeds a predetermined value A1 to a time point at which an output value (VO2—2) of second oxygen concentration detection means downstream of the catalyst exceeds a predetermined value A2, whereby an air-fuel ratio at next and subsequent restarts is corrected so that the atmosphere inside of the catalyst is optimized at the next and subsequent restarts.

    摘要: Provided is a paper-making machine belt (or a paper-making shoe-press belt), which is excellent in a wet-web water-squeezing property, which is stable in a paper quality (e.g., wet-web smoothness or marking property), and which has little damage (e.g., cracking or wear) of the outer circumference of the belt being used. The paper-making shoe-press belt carries a felt for accepting the squeezed water from the wet-web and has draining grooves extended in the felt-side surface. The paper-making shoe-press belt is characterized in that the draining grooves extended in the felt-side surface have at least two kinds of different groove shapes in the transverse direction (or the CMD direction) of the paper-making machine. The groove shape enables the grooves of two continuous and discontinuous kinds to share the functions thereby to satisfy the improvements in the drainage and in the paper quality and the wet-web surface smoothness at the same time.

    摘要: A belt for a shoe-press of a paper machine having water drain grooves which are resistant to the occurrence of cracks in side walls of the water drain grooves. The surface condition of the water drain grooves side wall is arranged to be a pear-skin state having minute unevenness. Preferably the surface has an average surface roughness in a range of 10 to 50 micrometers in at least the upper two thirds of the total distance (depth) of the side walls of the water drain grooves between the top of the groove and the bottom thereof. The water drain grooves can be manufactured by rotary cutting blades disposed in a position in contact with a roll around which a belt is wound. The roll and the rotary cutting blades rotate simultaneously and a groove cutting device is shifted in the width direction of the belt so that water drain grooves are formed in the belt. The belt running speed on the roll is set at 2 to 20 m/min, preferably 5 to 15 m/min, and rotation speed of the rotary cutting blades is set at 1,000 to 8,000 rpm.
