    • A method for controlling a motor-driven injection molding machine in which heat generation of a drive section including a drive motor is monitored, and when the drive section enters an overload state, the drive motor is stopped. In the method, during molding, heat generation value (overload factor) of the drive motor is estimated from load current flowing through the drive motor. When the estimated heat generation value (overload factor) reaches a preset stopping point or when a thermostat attached to the drive section outputs an overload detection signal indicating an overload state, the drive motor is stopped.
    • 一种用于控制电动机注射成型机的方法,其中监测包括驱动马达的驱动部分的发热,并且当驱动部分进入过载状态时,驱动马达停止。 在该方法中,在成型期间,通过驱动电动机的负载电流来估计驱动电动机的发热量(过载率)。 当估计的发热量(过载因子)达到预设的停止点时,或者当连接到驱动部分的恒温器输出表示过载状态的过载检测信号时,驱动电动机停止。

    • A concrete feeding tube, hereinafter referred to as a "tremie tube", is used to feed concrete grout or the like underwater. This tremie tube consists of an outer tube having desired rigidity and a number of through-holes, and an inner tube having desired pliability, the lower end of the inner tube being adapted to be closed with a closure means. The tremie tube is so designed as to be lowered vertically into a body of water with the lower end of the inner tube being closed with the closure means. So lowered, water is introduced through the aforesaid through-holes inwardly of the wall of the outer tube so as to collapse the inner tube with a resulting decrease in buoyancy of the tremie tube. When the lowered end of the outer tube reaches the water bed then fresh hardening-material, such as concrete grout, is fed into the inner tube under pressure so as to inflate the inner tube. The closure means is opened due to the pressure of concrete being fed therein thus allowing the concrete grout to be placed on the water bed.
    • 混凝土输送管(以下简称“颤音管”)用于水下灌注混凝土灌浆等。 该颤音管由具有期望的刚性和多个通孔的外管和具有期望的柔韧性的内管组成,内管的下端适于用闭合装置关闭。 颤音管被设计成垂直地下降到水体中,内管的下端用封闭装置封闭。 如此降低,水通过外管壁内的上述通孔引入,从而使内管塌陷,导致颤音管的浮力减小。 当外管的下端到达水床时,新鲜的硬化材料(例如混凝土灌浆)在压力下进入内管,以使内管膨胀。 封闭装置由于混合物的压力而被打开,从而使混凝土灌浆被放置在水床上。
