An emissions control system for a vehicle configured to travel on a road is provided. The microporous zeolite can include zeolite beta, zeolite Y or ZSM-5. In another aspect, the contact includes upper and lower contact portions one above the other arranged alternately staggered so as to be connected to a circuit board having contact portions alternately staggered, so that no defective connection occurs, even if the circuit board is inserted erroneously upside down. The first detector unit may receive the differential reference signals from the control unit and may receive first voltage signals from a first device under test located on the die or from a first area on the die. When a light receiving circuit region including the light receiving sensor is made a dark portion, and a region other than the light receiving circuit region is made a light portion, the display circuit and the light receiving sensor are disposed so that a spatial frequency of a repetitive pattern of the light portions and the dark portions becomes equal to or higher than 10 cpd. To enhance performance over a wider range of operating temperatures, the bore defined by the elastic flexible coating is formed with a plurality of waves and grooves which, like the teeth and tooth gaps of the bore are helical, but which have dimensions in both the circumferential and radial directions that are smaller than the dimensions of the teeth and tooth gaps of the bore.
