    摘要： The viscosity of a puncture-preventing sealant (7) is set in a range of 25 to 35 dPa·s, and a thixotropy index is set in a range of 6.5 to 11.0, the sealant (7) being filled in a sealant chamber (6) defined to extend along an outer periphery of an air chamber (5) in a tire (T). When the tire (T) is being rotated by traveling of a vehicle, the viscosity of the sealant (7) is reduced by a stirring action provided by a vibration or a centrifugal force of the sealant (7), whereby the sealant (7) can be diffused uniformly in the sealant chamber (6). When the vehicle has been stopped and the stirring action has been extinguished, the viscosity of the sealant (7) is increased, whereby the sealant (7) is maintained in a state in which it has been diffused uniformly in the sealant chamber (6) without flowing downwards in the sealant chamber (6) by gravitation. Therefore, even when the vehicle is travelling at a high speed, the generation of a vibration and a noise can be prevented. In this manner, the puncture-preventing sealant is provided, which has such a nature that the sealant is easy to flow due to a low viscosity during traveling of a vehicle, and the sealant is difficult to flow due to a high viscosity when the sealant is left to stand.

    摘要： A device for periodically estimating the temperature of an exhaust-gas purifying catalyst provided in the exhaust pipe of an internal combustion engine. The device includes first, second, third, and fourth estimation blocks. The first estimation block estimates the temperature of exhaust gases that are discharged from the combustion chamber, as a steady catalytic temperature under a steady operation of the internal combustion engine, based on operating conditions of the internal combustion engine. The second estimation block estimates a representative temperature of the interior wall of the exhaust pipe extending from the internal combustion engine to the catalyst, based on the estimated steady catalytic temperature. The third estimation block estimates a catalyst inflow exhaust-gas temperature that flows in the catalyst, based on the estimated steady catalytic temperature and the estimated representative temperature. The fourth estimation block estimates the temperature of the catalyst based on the estimated catalyst inflow exhaust-gas temperature.
