    摘要: The invention provides a heat recovery method for use in sulfuric acid production plants by which the heat generated in the step of drying SO2 gas or the step of drying air, and the step of absorbing sulfur trioxide in the plant is effectively utilized for heating the water to be supplied to a boiler although the heat is conventionally discarded because of the difficulties encountered in using the heat effectively. The boiler water to be supplied is heated by utilizing the heat generated by drying and/or absorption in a drying tower of the plant for drying sulfur burning air or the sulfur dioxide and/or in an absorption tower of the plant for causing circulating concentrated sulfuric acid to absorb sulfur trioxide produced by the conversion of the sulfur dioxide.

    摘要: In a vehicle vibration reduction control apparatus for controlling an alternator driven by an engine to charge a battery in such a way that vehicle body vibration due to the engine can be cancelled by alternator vibration, the reference voltage applied to an alternator field coil is reduced by a predetermined value for a predetermined time period, whenever battery terminal voltage exceeds a predetermined level. Since the battery charging rate can be reduced automatically at battery overcharge due to cancellation of engine vibration by alternator vibration, it is possible to prevent the battery from being overcharged when engine vibration increases at idling, for instance.

    摘要: A slide vane type compressor comprises a cam ring formed with at least one working chamber and a rotor arranged in the at least one working chamber with an outer peripheral surface of the rotor being disposed close to an inner wall surface of the cam ring at least at one axial sealing portion thereof, with the rotor being formed vane grooves for respectively accommodating a plurality of vanes. At least one suction port introduces gas into the at least one working chamber, with the suction port having a suction terminal point angle extending from the axial sealing portion to a terminal point of the suction port, as viewed in the direction of rotation of the rotor. The suction terminal point angle of the suction port is greater than a geometrical suction terminal point angle geometrically determined in dependence upon the number of working chambers and the number of the plurality of vanes so that the suction terminal point angle of the suction port is advanced as compared with the geometrical suction terminal point angle.
