摘要： In a double air-fuel ratio sensor system having three-way catalysts, a full O.sub.2 storage amount of the three-way catalysts is estimated and compared with a predetermined amount. When the estimated full O.sub.2 storage amount is smaller than the predetermined amount, the three-way catalysts are determined to have deteriorated.

摘要： The present invention resides in the provision of an intermediate frequency circuit in a television tuner capable of enlarging the attenuation of a audio IF carrier in an adjacent channel without increasing a loss in an intermediate frequency band. The intermediate frequency circuit comprises a mixer which outputs an intermediate frequency signal, an intermediate frequency amplifier for amplifying the intermediate frequency signal outputted from the mixer 1, and a feedback circuit disposed between an input end and an output end of the intermediate frequency amplifier, and in the intermediate frequency circuit, a audio IF carrier of an adjacent intermediate frequency signal adjacent to the intermediate frequency signal is fed back from the output end to the input end of the intermediate frequency amplifier by the feedback circuit.

摘要： A fuel evaporative-gas emission preventing apparatus capable of reducing the quantity of adsorption of a canister as low as possible by a single breather at any fueling speeds and allowing emissions to fall within given limits. One end of the breather is coupled to a portion near a port of an inlet pipe for a fuel tank and a differential pressure regulating valve is connected to the other end of the breather. The canister is coupled to the differential pressure regulating valve. An opening-area variable device is provided at an intermediate portion of the breather and adjusts the quantity of a fuel evaporative-gas in the breather according to an internal pressure of the fuel tank.
