    • A predetermined value is used for adjusting welding power to an optimum value to consistently achieve sturdy welds. The predetermined value is not affected by variations in workpiece materials and in wear of electrodes. Preferably, total power per unit volume of the workpieces is used as the predetermined value. In a resistance welding system, total power per unit volume required to satisfactorily weld the workpieces is calculated from a total thickness of the workpieces and a welding time. From this calculated total power per unit volume, power per unit volume and per unit time is calculated. The present welding system adjusts one of the welding current or the welding voltage to an optimum value required to produce the predetermined value.
    • 使用预定值将焊接功率调整到最佳值,以始终如一地实现坚固的焊接。 预定值不受工件材料变化和电极磨损的影响。 优选地,将每单位体积的工件的总功率用作预定值。 在电阻焊接系统中,从工件的总厚度和焊接时间计算出满意地焊接工件所需的每单位体积的总功率。 根据该计算出的每单位体积的总功率,计算每单位体积的功率和每单位时间的功率。 本焊接系统将焊接电流或焊接电压中的一个调整为产生预定值所需的最佳值。

    • A magnetic head assembly including a carriage which carries thereon a first magnetic head for information writing and reading to and from one side of a disc-like magnetic recording medium, and a hold case which carries thereon a second magnetic head for information writing and reading to and from the other side of the magnetic recording medium, the second magnetic head being disposed in a position opposed to the first magnetic head, the hold case being connected to the carriage through hinge means rotatably to a certain degree relative to the carriage, and the magnetic head assembly being reciprocated in a radial direction of the magnetic recording medium. The first magnetic head is mounted on the carriage through a gimbal spring which is formed rotatably to a certain degree with respect to biaxial hinge portions, and the second magnetic head is mounted on the hold case through a spring plate which is formed rotatably to a certain degree with respect to a uniaxial hinge portion. The hold case is urged toward the carriage on the side of the hinge means rotatably to a certain degree relative to the carriage.
