    • A coating apparatus wherein the coating is made by a coater while a support is carried in a non-contacting manner by a gas jetted from a gas jetting device towards the support. The gas jetting device has a hollow housing into which the gas is introduced from a gas source, the wall of the housing adjacent to the support being provided with a plurality of gas jetting nozzle ports through which the gas is jetted towards the support, each gas jetting nozzle port having a throat portion presenting a minimum cross-sectional area inwardly spaced from the outer surface of the wall of the housing and an enlarged outlet portion presenting a comparatively large diameter and opening in surface of the wall. The ratio of port area is adjusted in such a manner that the rate of jetting of the gas from unit area of the outer surface of the gas jetting device becomes smaller as the width of the support is increased.
    • 一种涂覆装置,其中涂层由涂覆机制成,而支撑体以非接触方式通过从气体喷射装置向支撑件喷射的气体运送。 气体喷射装置具有中空壳体,气体从气体源引入到其中,与支撑件相邻的壳体的壁设置有多个气体喷射喷嘴端口,气体朝向支撑件喷射,每个气体 具有喉部的喷射喷嘴端口具有与壳体的壁的外表面向内间隔开的最小横截面面积,以及具有相对较大的直径并且在壁的开口表面的扩大的出口部分。 端口面积的比率被调节为使得气体从气体喷射装置的外表面的单位面积喷射的速率随着支撑件的宽度增加而变小。

    • A stepping motor control circuit includes a rotation detecting means which detects an induced signal generated by rotation of a rotor of a stepping motor, and detects a rotation state of the stepping motor according to whether the induced signal exceeds a predetermined reference threshold voltage in a predetermined detection section, and a control means which controls driving of the stepping motor by using any one of a plurality of main driving pulses having energies different from each other or a correction driving pulse with energy higher than energy of each main driving pulse according to a detection result of the rotation detecting means. The detection section is divided into a first section immediately after driving by the main driving pulse, a second section after the first section and a third section after the second section. During the driving of the stepping motor by the main driving pulse, when the rotation detecting means has detected an induced signal exceeding a first reference threshold voltage in the first section and the second section, if an induced signal exceeding a second reference threshold voltage lower than the first reference threshold voltage is not detected in the third section, the control means drives the stepping motor by using the correction driving pulse.
    • 步进电动机控制电路包括旋转检测装置,其检测由步进电动机的转子旋转产生的感应信号,并且根据感应信号是否超过预定的参考阈值电压来检测步进电动机的旋转状态 检测部分和控制装置,其通过使用具有彼此不同的能量的多个主驱动脉冲中的任何一个来控制步进电机的驱动,或者根据检测来控制具有高于每个主驱动脉冲的能量的能量的校正驱动脉冲 旋转检测装置的结果。 检测部分通过主驱动脉冲被分成紧接在驱动之后的第一部分,第一部分之后的第二部分和第二部分之后的第三部分。 在通过主驱动脉冲驱动步进电机的过程中,当旋转检测装置在第一部分和第二部分检测到超过第一参考阈值电压的感应信号时,如果超过第二参考阈值电压的感应信号低于 在第三部分中没有检测到第一参考阈值电压,控制装置通过使用校正驱动脉冲来驱动步进电机。
