摘要： A small, low-cost, wide-range current sensor excellent in environmental resistance and noise resistance and high in accuracy. A dc magnetic field is applied to two magnetic elements (1a, 1b) having a magnetic impedance effect by means of a magnet (3), while a negative feedback magnetic field is applied to both elements by means of a coil (2). The variation of the magnetic field depending on the external magnetic field applied to the magnetic elements (1a, 1b) by the magnetic element (1a, 1b) is measured by detection means (7a, 7b). The difference between the outputs is amplified by a differential amplifier means (8). Thus detection of wide range is achieved while eliminating the influence of the noise. A device to which such a sensor is applied is also disclosed.

摘要： The invention provides a method and device for decomposing environmental pollutants, capable of decomposing organic halogen compounds, etc., which are environmental pollutants in a short time and in large quantities to such a low concentration degree that allows them to be discharged as drainage into a sewage pipe or the like and also capable of decomposing organic substances, nitrogen, phosphorous, etc., which are hard to oxidation-decompose. To a sample solution (20) in a reaction vessel (10a) storing an aqueous solution containing environmental pollutants, a vibrator (30a) placed on the central bottom of the reaction vessel (10a), for example, radiates ultrasonic waves (50), and at the same time, ultraviolet lamps (40a) disposed on the peripheral edge within the reaction vessel (10a) radiate ultraviolet rays. On this occasion, the ultraviolet lamps (40a) are disposed at positions where they substantially do not interfere with the path of travel of ultrasonic waves (50).
