    • A process control apparatus controls a focus position of a laser beam, while a laser processing mechanism converges the laser beam into a predetermined focus position and performs a laser processing on a workpiece. The process control apparatus includes: a calculator that, based on the magnitude of an output of the laser beam that changes during the laser processing, calculates a change amount of a positional deviation of the focus position in an optical axis direction that changes during the laser processing at a laser beam radiation position; and a control unit that, based on the change amount of the positional deviation that has been calculated by the calculator, controls the focus position of the laser beam during the laser processing so as to resolve the positional deviation of the focus position.
    • 过程控制装置控制激光束的焦点位置,而激光加工机构将激光束会聚到预定的聚焦位置,并对工件进行激光加工。 该处理控制装置包括:计算器,其基于在激光处理期间发生变化的激光束的输出的大小来计算在激光器内变化的光轴方向上的聚焦位置的位置偏差的变化量 在激光束辐射位置处理; 以及控制单元,其基于由计算器计算出的位置偏差的变化量来控制激光处理期间的激光束的聚焦位置,以便解析聚焦位置的位置偏差。

    • A voltage controller has a control circuit and a heat radiating member attached to the circuit. The circuit controls a voltage of electric power generated in an alternator of a vehicle while generating heat. The member has a first surface and a second surface. The second surface of the member is formed in a smooth shape having no protrusions or hollows. A cooling wind flows on the second surface. The member receives the heat from the control circuit through the first surface and radiates the heat from the second surface to the wind.
    • 电压控制器具有附接到电路的控制电路和散热构件。 该电路控制在车辆的交流发电机中产生的电力的电压,同时产生热量。 该构件具有第一表面和第二表面。 构件的第二表面形成为没有突起或中空的平滑形状。 冷却风在第二表面上流动。 该构件通过第一表面接收来自控制电路的热量,并将热量从第二表面辐射到风中。
