    • A control device for an electric injection molding machine designed to advance and retract a screw in a heating cylinder by an injection motor includes a screw position detector for detecting a screw position to output a screw position detection signal, a speed pattern generator for generating a speed setting pattern signal which indicates relationship between time and screw speed. An integration unit integrates the speed setting pattern signal to obtain a moving stroke of the screw. And a generation unit generates a position instruction signal on the basis of the moving stroke and a screw position when injection is initiated. To generate a speed instruction signal, the screw position detection signal is subtracted from the position instruction signal as a manipulated variable of feedback and the speed setting pattern signal is applied to the position instruction signal as a manipulated variable of feed forward. Thus, accuracy at the speed changing positions can be improved, thus improving operability.
    • 一种用于通过注射马达推进和缩回加热缸中的螺杆的电动注射成型机的控制装置,包括用于检测螺杆位置以输出螺杆位置检测信号的螺钉位置检测器,用于产生速度的速度模式发生器 设定时间与螺杆速度关系的模式信号。 集成单元集成了速度设定模式信号以获得螺杆的移动行程。 生成单元基于移动行程和喷射开始时的螺杆位置生成位置指示信号。 为了产生速度指令信号,从作为反馈的操作变量的位置指令信号中减去螺杆位置检测信号,并且将速度设定模式信号作为前馈的操作变量施加到位置指令信号。 因此,能够提高变速位置的精度,提高可操作性。

    • In a continuously variable transmission of the type in which a speed change ratio is changed in a manner that the radius of rotation of a belt wound around a drive pulley and a driven pulley is varied by changing the width of a groove between the pulley parts of each pulley with an oil pressure. A control means for controlling an oil pressure in various control modes shifts the control mode from a hold mode to a start mode, when a driver manipulates a vehicle carrying the continuously variable transmission with his intention to start the vehicle, and an amount of discharge flow of an oil pump for generating an oil pressure exceeds a preset value. The safety factor in a stationary state is calculated using the effective tension of the CVT belt, secondary side oil pressure, and the speed change ratio. Using the calculated stationary state safety factor, a manipulated variable previously gained, and a changing rate of the primary oil pressure, a safety factor in a speed change state (transient state) is calculated. A manipulated variable of the speed change control means is limited so that the safety factor in a speed changing state exceeds a predetermined value. When the speed change performance may be damaged with the limitation of manipulated variable, a necessary quantity of the line pressure or the CVT input torque is corrected so as to increase the limit value.
