    • In a burner igniter using a ceramic heater, the resistance of the ceramic heater is detected to perform feedback control so that the temperature of the heater is maintained substantially constant to prevent both misfiring and overheating, while rapid temperature rise can also be obtained. The resistance value detected by a bridge circuit is fed to a proportional-integral controller which produces a control signal, while the current fed to the ceramic heater is also detected. The control signal and another signal indicative of the current to the ceramic heater are used to control a power source of the ceramic heater so that the current to the ceramic heater is controlled. A monitoring circuit responsive to both the resistance of the ceramic heater and the current fed to the ceramic heater may be added to warn a user that the life of the ceramic heater will soon end. The ceramic heater may comprise a portion having negative temperature coefficient, through which portion leak current would flow when the temperature of the ceramic heater rises so as to prevent overheating.

    • A method and an apparatus for controlling the hot-wire welding process is disclosed in which the heating power for a hot-wire is automatically regulated to a proper value. The wire-heating power after fusing of a filler wire by being overheated is set to a level lower than the heating power immediately before wire fusing, and the wire-heating power is again increased gradually from the set value until the wire is fused by being overheated. By repeating this process, the molten state of the filler wire in the hot-wire TIG welding is automatically kept in optimum condition without requiring any operation of the welding operator or his intuition. Further, during the energization of the filler wire, the instant of fusing by overheating of the wire is detected, and the detected signal is used to sharply reduce or suspend the wire current immediately, whereby spatters which otherwise might be caused by fusing of the overheated wire is prevented or greatly reduced, and the adhesion of the spatters to the arc electrode is prevented, thereby permitting a hot-wire welding operation continuously over a long time. Furthermore, a pulsed current is used for heating the filler wire, and the wire terminal voltage during de-energization of the wire is detected, thereby detecting whether the wire is in contact with a base metal. If the wire is not in contact with the base metal, a current is not supplied during the next pulse application period, so that the current is prevented from flowing from a tungsten electrode to the wire while the wire is not in contact with the base metal.
    • 公开了一种用于控制热丝焊接工艺的方法和装置,其中热丝的加热功率被自动调节到适当的值。 通过过热将填充线熔接后的线加热功率设定为低于线熔点之前的加热功率的水平,并且线加热功率再次从设定值逐渐增加,直到线熔断为止 过热 通过重复该过程,热丝TIG焊接中的焊丝的熔融状态自动保持在最佳状态,而不需要焊接操作者的任何操作或他的直觉。 此外,在填充线的通电期间,检测到线的过热的熔化瞬间,并且检测到的信号用于立即急剧地减少或暂停线电流,从而由于过热的熔化而引起的飞溅 防止或大大降低线,并且防止飞溅物与电弧电极的粘附,从而允许长时间连续地进行热丝焊接操作。 此外,使用脉冲电流来加热填充线,并且检测线的断电期间的线端电压,从而检测线是否与贱金属接触。 如果导线不与基体金属接触,则在下一个脉冲施加期间不提供电流,从而防止电流从钨电极流向导线,同时电线不与基体金属接触 。

    • A moving apparatus for a load lifts the load by the torque of a motor, and balances and holds the same with the aid of a mechanical brake when the apparatus stops. A timing device is incorporated in brake control so that when the apparatus stops in response to a signal indicating that a zero speed is designated, the mechanical brake is operated with a time lag after the receipt of the signal and, as soon as the brake is applied, the power supply to the motor is cut off. This arrangement remarkably reduces the impact of stopping upon the mechanical brake and drive, lessens the wear of the brake, permits reduction in size of the components and extends the service life of the components, thus providing an apparatus which saves power in comparison with conventional equipment.
    • 用于负载的移动装置通过电动机的扭矩提升负载,并且当装置停止时借助机械制动器平衡并保持负载。 定时装置被并入制动控制中,使得当装置响应于指示零速度的信号停止时,机械制动器在接收到信号之后以时间延迟运行,并且一旦制动器 应用时,电机的电源被切断。 这种布置显着地减少了停止在机械制动和驱动上的影响,减小了制动器的磨损,允许部件的尺寸减小并且延长了部件的使用寿命,从而提供了一种与常规设备相比节省功率的装置 。
