摘要： The present invention discloses a NOx sensor for accurately detecting the total concentration of nitrogen oxides in a measured gas without being affected by interference gases. The sensor comprises a gas treatment chamber 5 arranged at the prior stage of the gas detection chamber 3, an inorganic porous member 25 loaded in the gas treatment chamber, and a NOx conversion pumping cell 14,15 and/or an oxygen supplying pumping cell which supplies oxygen into the gas treatment chamber. When the measured gas is introduced in the gas treatment chamber, the interference gases contained in the measured gas are effectively oxidized by the supplied oxygen under the assistance of the catalytic activity of inorganic porous member. The total amount of the nitrogen oxides is measured in the gas detection chamber while NOx in the measured gas are converted into a single component (NO 2 or NO) by the NOx conversion pumping cell after the interference gases are oxidized.

摘要： An amorphous hard carbon film has low friction coefficient from the beginning of sliding, when the metal oxide is contained in the film. The adhesion of the film to the substrate is also improved due to the low temperature treatment of RF plasma enhanced CVD method. This film can be applied to many sliding members, e.g., a piston ring, a vane of compressor and a plunger of fuel injection pump, used under severe condition.

摘要： The sensing unit (3) of a heating-type sensor is kept at a constant high temperature by a main heater (30) and an auxiliary heater (32). A leakage current caused by the deterioration of an insulating board (2) is absorbed by a guard heater. The sensing unit which can be kept at a high temperature, for instance 400°C, and a heat conducting insulating board or film (2) on which the main heater and auxiliary heater are provided closely to each other are included. Or, a leakage current preventive guard heater is provided adjacent to the auxiliary heater side between the main heater and the auxiliary heater. A bridge circuit (18) has the auxiliary heater on its one side and has a 1st resistor (12), a 2nd resistor (14) and a 3rd resistor (16) on the other three sides. A heating control circuit has an amplifier or a voltage follower (20) and an amplifier (24) whose reverse input terminal is connected to a series connection point between the 1st resistor and the auxiliary heater, whose non-reverse input terminal is connected to a series connection point between the 2nd resistor and the 3rd resistor and whose output terminal is connected to the control input terminal of the voltage follower. The amplifier controls a voltage applied to the bridge circuit and the main heater in accordance with output of the bridge circuit. A 2nd amplifier (52) controls the voltage at a connection point (50) to the guard heater (40) so as to be equal to the voltage of a connection point (13) to the auxiliary heater in accordance with the output or a 2nd bridge circuit (44) including the auxiliary heater and the guard heater (40).
