    • A packaging bag is provided with a bag body and thermoplastic resin-made reinforcing members provided at the outer edge of the bag body. A window is provided in each reinforcing member. In forming the packaging bag, the bag body is placed between a pair of molds respectively having recesses to clamp these two molds so that a corresponding pair of the recesses are opposed to each other. Thereafter, in order to form the reinforcing members at the outer edge of the bag body, melted or softened thermoplastic resin is injected to fill cavities formed by the recesses of the thus clamped molds. Each of the cavities of the molds is formed so as to coincide with an outer shape of the corresponding reinforcing member. A projection extends from the bottom face of each recess at a part of the cavity corresponding to a part of each reinforcing member on which the window is provided. The outer edge of the bag body placed between the two molds is placed inside the cavities in a state of being held between the two projections.
    • 包装袋设置有袋体和设置在袋体外缘的热塑性树脂加强件。 在每个加强构件中设置有窗口。 在形成包装袋时,将袋体放置在分别具有凹部的一对模具之间,以夹持这两个模具,使得相应的一对凹部彼此相对。 此后,为了在袋体的外缘形成加强构件,注入熔融或软化的热塑性树脂以填充由这样夹紧的模具的凹部形成的空腔。 模具的每个空腔形成为与相应的加强构件的外部形状一致。 突起从凹部的底面延伸到空腔的与设置有窗口的每个加强构件的一部分相对应的部分。 放置在两个模具之间的袋体的外边缘处于保持在两个突起之间的状态下的空腔内。

    • In a digital servo control system (31) for a carriage of a serial printer or a like movable element, a control signal (125) digitally represents a reference angular velocity for a motor (26) until an instant at which a displacement from a current position of the element to a commanded position decreases to a predetermined value, a positional error during a preselected interval following the instant, and an integrated value (52) of a position error between the current and the commanded positions to suppress limit cycle after the interval. A PWM signal (56-57) is derived from the control signal and position pulses (62 or 63) representative of a variation in the current position. Preferably, small-amplitude limit cycle is forced to occur during the interval with the positional error indicated by a modified signal (182) derived by adding unity to positive and zero position errors.
    • 在用于串行打印机或类似可移动元件的滑架的数字伺服控制系统(31)中,控制信号(125)数字地表示电动机(26)的参考角速度,直到从电流 元件到命令位置的位置减小到预定值,在瞬间之后的预选间隔期间的位置误差以及当前和指令位置之间的位置误差的积分值(52),以抑制间隔之后的极限循环 。 PWM信号(56-57)从控制信号和表示当前位置变化的位置脉冲(62或63)导出。 优选地,在间隔期间强制发生小振幅极限循环,其中由通过将正和零位置误差加起来导出的修正信号(182)所指示的位置误差。
