    • PROBLEM TO BE SOLVED: To provide a technology for eliminating blockage to suppression of a higher harmonic wave component in a power supply current caused by arithmetic processing in a current controller in an active filter.SOLUTION: A current controller 5 performs processing for generating a three-phase voltage command value V* on the basis of output from a differential current generation section 3A. The current controller 5 performs e.g., PI (proportional integration) control to implement the processing, such that a delay time ta is generated. In the case where a deviation Ie is determined from a command value Ic* and a compensation current Ic, the time ta causes deviation between the compensation current Ic and a higher harmonic wave component and becomes a blockage factor to suppressing the higher harmonic wave component in a power supply current Is. In the differential current generation section 3A, however, the deviation Ie is determined from the value Ic*^ obtained by advancing a phase of the command value Ic* in accordance with the time Ta and the compensation current Ic, thereby eliminating or reducing the blockage factor.
    • 要解决的问题:提供一种用于在有源滤波器中的电流控制器中由算术处理引起的电源电流中消除阻塞高次谐波分量的技术。解决方案:电流控制器5执行用于产生三 基于来自差动电流产生部3A的输出的相电压指令值V *。 电流控制器5例如执行PI(比例积分)控制以实现处理,使得产生延迟时间ta。 在从指令值Ic *和补偿电流Ic确定偏差Ie的情况下,时间ta导致补偿电流Ic与高次谐波成分之间的偏差,并成为抑制高次谐波成分的阻塞因子 电源电流Is。 然而,在差动电流产生部3A中,通过根据时间Ta和补偿电流Ic推进指令值Ic *的相位而获得的值Ic * ^来确定偏差Ie,从而消除或减少阻塞 因子。

    • PROBLEM TO BE SOLVED: To provide a heat exchanger capable of preventing distortion of a desiccant case in mounting a plug of a liquid receiver on a cylindrical body.
      SOLUTION: This heat exchanger 1 includes: a pair of tanks 2, 3; a plurality of heat exchange tubs 4 disposed between both tanks 2, 3; fins 5 respectively disposed between the adjacent heat exchange tubes 4; the liquid receiver 7 mounted on one of the tanks 2; and the desiccant case 30 disposed in the liquid receiver 7 and having a desiccant. The liquid receiver 7 has a cylindrical body 26 vertically extended and opened at its top end, and a columnar plug 28 screwed and fitted into a top end opening of the cylindrical body 26. A female screw is formed on an inner peripheral face of the top end opening of the cylindrical body 26, and a male screw engaged with the female screw is formed on an outer peripheral face of the plug 28. The desiccant case 30 containing the desiccant in a bag is mounted to the plug 28 through a suspending means freely rotatably around an axis of the plug 28.
