    摘要: A gas sensor includes a measurement gas chamber into which a measurement gas is introduced. An oxygen pumping cell adjusts an oxygen concentration in the measurement gas chamber. An oxygen monitor cell has a monitor electrode exposed in the measurement gas chamber. The monitor electrode has an oxidizing activity with respect to a specific component of the measurement gas. A sensor cell has a sensor electrode exposed in the measurement gas chamber. The sensor electrode has an oxidizing activity with respect to the specific component of the measurement gas which is lower than the oxidizing activity of the monitor electrode. An oxygen-ion current in the oxygen monitor cell is detected. An oxygen-ion current in the sensor cell is detected. A concentration of the specific component of the measurement gas is detected from a relation between the detected oxygen-ion currents in the oxygen monitor cell and the sensor cell.

    摘要: There is disclosed an apparatus for carrying an information recording medium, in which recording of information on and/or reproduction of information from the recording medium is effected by causing a base for holding the recording medium to reciprocally move to an optical head for recording and/or reproducing. The apparatus has a feeding mechanism for feeding the recording medium to the base, and an ejecting mechanism for ejecting the recording medium from the base. The ejecting mechanism is provided on the base.

    摘要: A piezoelectric ceramic composition is disclosed wherein a sintered body having a bismuth layer structure represented by a molecular formula of PbBi.sub.4 Ti.sub.4 O.sub.15 contains 10 to 55 mol % of an oxide of Ca and Ti, namely CaTiO.sub.3, or 1 to 15 mol % of an oxide of Sr and Ti, namely, SrTiO.sub.3. The bismuth layer structure of PbBi.sub.4 Ti.sub.4 O.sub.15 has a positive dielectric-constant-temperature characteristic, and CaTiO.sub.3 or SrTiO.sub.3 is obtained by sintering as an added substance exhibiting a negative dielectric-constant-temperature characteristic. Since the added substance is added to the piezoelectric ceramic composition so that the temperature changes in both dielectric constants are mutually cancelled out, thereby maintaining the piezoelectric constants at a substantially fixed level.

    摘要: Radioactive organic wastes, such as granular or powdered ion exchange resins and organic filter aids, are treated by oxidation decomposition using hydrogen peroxide in the presence of iron ions in an aqueous medium under refluxing an effluent which is condensed from evaporated components during the oxidation. Condensed water containing a very small amount of organic matter is obtained.

    摘要: A developing unit includes a developer bearer to bear developer on a surface thereof, first and second developer conveyors each having a spiral blade mounted on a rotary shaft thereof parallel to a rotary axis of the developer bearer to convey developer in opposite directions to each other. A developer drain hole is provided at a given height in a side wall of a second developer conveyance channel to face a communication opening across the second developer conveyor. The first developer conveyor rotates in a direction with its spiral blade rising between the rotary shaft of the first developer conveyor and the communication opening. Rotational phases of the first developer conveyor and the second developer conveyor are fixed and synchronized with each other to weaken momentum of developer flow generated by the first developer conveyor toward the developer drain hole via the second developer conveyor.
