    摘要: A soft-film-bias type magnetoresistive device is disclosed in which a high-permeability magnetic film, an insulating film and a permalloy film are formed on a substrate in this order, and first, second and third electrodes, which are parallel to each other, are provided on the permalloy film, to form a differential type magnetoresistive device. In this magnetoresistive device, a bias magnetic field which is generated and applied to the permalloy film between the first and second electrodes, is opposite in direction to a bias magnetic field which is generated and applied to the permalloy film between the second and third electrodes.

    摘要: A magneto-resistive type read head has a substrate, a magnetic film exhibiting a magneto-resistive effect arranged in the widthwise direction of the track of a magnetic writing disk, and lead electrodes for feeding an electric current to the track width portion of the magnetic film for reading the signals written in the magnetic writing disk. The magneto-resistive film extends over a width wider than the track width portion and a soft magnetic thin film is formed over the magneto-resistive film on either side of the track width portion to absorb the domain wall so that the magneto-resistive film takes the single domain structure.

    摘要: It is intended to provide an exhaust gas treatment system, which allows for VOC removal at lower temperatures and thereby improves the durability of catalysts and suppresses carbon monoxide generation at the final outlet of the system. The present invention provides a treatment system of an exhaust gas containing a nitrogen oxide, carbon monoxide, and a volatile organic compound comprising: an exhaust gas treatment means for removing the nitrogen oxide by reduction with ammonia and partially oxidizing the VOC to CO; and a CO/VOC removal means for oxidizing the CO and partially unreacted VOC, in this order from the upstream flow of the exhaust gas.
