    摘要: In a recording apparatus for stably conveying a recording medium to a recording portion by a convey belt, the recording medium is passed through a nip of a pair of separation supply rollers and enters into a nip between a convey belt and a driven roller and thereafter is conveyed by the convey belt to a recording portion. When a leading end of the recording medium is detected by a recording medium detect sensor, the supply roller is disengaged from the separation roller, so that the convey belt is not subjected to the influence of the pair of separation supply rollers via the recording medium and when a trailing end of the recording medium is detected by a recording medium detect sensor, the driven roller is disengaged from the convey belt, so that the recording medium is not subjected to conveyance resistance from the driven roller.

    摘要: A three-way catalyst (20) having an oxygen storage function and an exhaust purification catalyst (22) are arranged in the exhaust passage of an internal combustion engine. During medium-load operation of the engine the degree of lean of the air-fuel ratio in the combustion chamber (5) is increased so as to increase the oxygen storage amount of the three-way catalyst (20) to the maximum oxygen storage amount, and the air-fuel ratio in the combustion chamber (5) even after the oxygen storage amount of the three-way catalyst (20) has reached the maximum oxygen, storage amount is maintained at lean, after which the air-fuel ratio is returned to rich, and at this time, as the amount of poisoning of a noble metal catalyst when the air-fuel ratio in the combustion chamber (5) is rich increases, the amount of time for which the air-fuel ratio in the combustion chamber (5) is maintained at lean is increased.

    摘要: On an upper surface of a fixed substrate, a plurality of strap-shaped base electrodes are arranged in parallel to each other. On each of the base electrodes, an electret is formed. The electret has a width wider than the width of each base electrode, and the electret covers an exposed surface of the base electrode. A movable substrate is disposed in parallel to and facing the surface of the fixed substrate where the electrets and others are formed. The movable substrate is movable relatively to the fixed substrate. On a facing surface of the movable substrate, strip-shaped counter electrodes are each formed so as to face each base electrode.

    摘要: An accurate determination of deterioration of a NOx storage reduction catalyst. A supply device supplies a reducing agent to the NOx catalyst to change an air fuel ratio of an exhaust gas passing through the NOx catalyst, an NH3 detection device detects NH3 in the exhaust gas at the downstream side of the NOx catalyst, a control device adjusts an amount of the reducing agent so that the air fuel ratio of the exhaust gas becomes a predetermined rich air fuel ratio, and a determination device makes a determination that the NOx catalyst has deteriorated, when a detected value of the NH3 detection device becomes equal to or greater than a threshold value, at the time of supplying the reducing agent while adjusting the amount of the reducing agent so that the air fuel ratio of the exhaust gas becomes the predetermined rich air fuel ratio.
