    摘要: An air fuel ratio detecting arrangement using a diffusion suppressing type air fuel ratio sensor applicable to an air fuel ratio control unit for an internal combustion engine incorporating an atmospheric air pressure correction circuit in a signal processing and outputting device for correcting an output voltage signal processed therein based on a change in atmospheric air pressure which is detected when a predetermined operating condition of an internal combustion engine is satisfied. A secular change correction circuit included in the signal processing and outputting device detects a change in electromotive force of a concentration cell portion of the air fuel ratio sensor when a predetermined rich air fuel ratio is reached and corrects a reference voltage for the air fuel ratio sensor based on the detected change in electromotive force of the concentration cell portion in addition to an air calibration circuit.

    摘要: A method and apparatus are disclosed for measuring atmospheric pressure in conjunction with an air-fuel ratio sensor of the type comprising a concentration cell with atmospheric air and exhaust electrodes on opposite sides of a solid-state electrolyte having oxygen ion conductivity. During an atmospheric pressure measuring cycle, oxygen ions are pumped from the atmospheric air electrode to the exhaust electrode, in a quantity which is either predetermined at a fixed value, or is sufficient to bring the cell to an equilibrium state. Atmospheric pressure is then calculated from measured emf of the cell, using an experimentally derived functional relationship. In a second embodiment, ions are pumped until a predetermined change of the concentration cell emf is achieved, and atmospheric pressure is determined based on the amount of time required to achieve such change. The atmospheric pressure measuring mode is operated on a time shared basis with the air-fuel ration detection mode.

    摘要: The flexible exothermic medium of this invention is composed of an exothermic agent which generates heat in contact with air, and a water-absorptive polymer and/or a second polymer other than the water absorptive polymer. The mixture thereof is pressed at a pressure of 100-8000 kg/cm2 with alcohol, a cross-linking agent or a plasticizer. This results in producing flexible united mediums. The flexibility of the exothermic medium is also obtained by irradiating it with light or heating the mixture.The exothermic medium thus prepared is so flexible as to fit any curved part the body and has excellent exothermic characteristics compared with the prior art.The heating element using these exothermic mediums is fit for various uses such as thermotherapy, body warmers, cosmetics and the like.
