摘要： An operation to acquire a strip with less thickness even if arcuate worn steps are formed on side weirs is disclosed. During an operation of a twin-roll casting machine with arcuate worn steps developing on side weirs due to rotational sliding contact of chilled rolls, the thickness of a steel strip from a nip is reduced, and the center-to-center distance between the rolls is increased with the side weirs in contact with ends of the rolls being displaced upward. This prevents interference of outer peripheries of the rolls with boundary surfaces adjacent to the arcuate worn steps of the side weirs.
摘要翻译：公开了即使在侧面堰上形成弓形磨损台阶的情况下获得厚度较小的钢带的操作。在由于冷轧辊的旋转滑动接触而在侧堰上形成弓形磨损步骤的双辊铸造机的操作期间，来自辊隙的钢带的厚度减小，并且辊之间的中心到中心距离随着与辊的端部接触的侧堰向上移位而增加。这样可以防止辊边缘与侧面堰的弧形磨损步骤相邻的边界面的干扰。

摘要： A combined bias circuit in which a voltage drive bias circuit and a current drive bias circuit are provided in parallel with each other has a configuration in which a linearizer including a first resistor is connected between an amplifying transistor and a second resistor. This configuration ensures that even when a low voltage of 2.4 to 2.5 V is supplied as an external reference voltage, the amplifying operation can be performed while generally constantly maintaining an idling current in a temperature range from a low temperature to a high temperature, and that degradation in distortion characteristics during low-temperature operation can be limited.
