摘要： An oxygen analyzing method for determining a positive or negative oxygen concentration of a measurement gas which changes between oxidizing and reducing atmospheres. The method uses a sensing element having an oxygen sensing cell wherein an electromotive force is induced between its measuring and reference electrodes according to the principle of an oxygen concentration cell. The atmosphere adjacent to the measuring electrode is controlled by controlling a pumping current to be applied to an oxygen pumping cell such that the electromotive force induced in the sensing cell is maintained at a predetermined level. A heater is provided to heat the sensing and pumping cells, to maintain their operating temperature within a range of 700.degree.-960.degree. C. The pumping current, or a signal to control the pumping current, is converted into an oxygen concentration signal whose level is held within one of a positive range and a negative range. The concentration signal represents the positive oxygen concentration of the oxidizing atmosphere, or the negative oxygen concentration of the reducing atmosphere.

摘要： Provided is an optical displacement meter capable of accurately detecting a displacement of an object. A light-projecting part selectively irradiates a workpiece with first and second light whose polarization directions are different from each other. Reflected light from the workpiece is incident on a light-receiving element through a light-receiving lens. A waveform creating part creates first and second waveform data showing light-receiving amount distributions of the first and second light obtained by the light-receiving element. A waveform processing part calculates a ratio between mutually corresponding peaks in the first and second waveform data, and selects one peak from each of the first and second waveform data based on the calculated ratios, to detect a position of the peak.
