    • A device for determining activation of an air-fuel ratio sensor comprising an air-fuel ratio sensor arranged in an exhaust system of an engine and having a heater for heating an oxygen concentration cell element and an oxygen pump element, a current flowing means for flowing a predetermined current from a first electrode of the concentration cell to a reference electrode, a pump current controlling means for controlling current flowing in the pump element so that a sensor voltage between the reference electrode and the first electrode becomes a reference voltage, a pump current detecting means, a current flow cutting means, a sensor voltage detecting means, a heater power supplying means, and a timer means operated at every predetermined time interval for starting the heater supplying power means to the heater during a pump-current-cut state and for operating the current flow cutting means during the predetermined time interval. The air-fuel ratio controlling device determines the activation of the sensor by the difference between the sensor voltage before and after the current flow cutting means is operated and releases the pump-current-cut state when the sensor is determined to be activated.

    • An object of the present invention is to provide an atmosphere heat treatment apparatus that is operable without relying on experiences and/or intuitions of an operator, and a method of operating the same. The atmosphere heat treatment apparatus includes an entrance side exhaust path (26) for exhausting an inside atmosphere from an entrance side of a carburizing chamber (10) to which a transforming gas is supplied, an exit side exhaust path (35) for exhausting the inside atmosphere from an exit side of the heat treatment chamber, and an opening degree adjusting lid (28) attached for adjusting an opening degree of the entrance side exhaust path (26), in which a part or whole of the exit side exhaust path (35) is constituted of a pipe (46) having a predetermined inside diameter. It is checked in advance a relationship of a supplying amount A of the transforming gas with a ratio B:C of an exhaust amount B from the exit side exhaust path (35) and an exhaust amount C from the entrance side exhaust path (26) when a pressure in the carburizing chamber (10) is adjusted to a predetermined furnace pressure by adjusting an opening degree of the entrance side exhaust path (26) with the opening degree adjusting lid (28), and when treating a work (W), the supplying amount A of the transforming gas and a furnace pressure are adjusted so as to control the ratio B:C of the exhaust amount B from the exit side exhaust path (35) and the exhaust amount C from the entrance side exhaust path (26) to be within a predetermined range.
