    • A method is provided to cut a thin-walled member without causing chattering vibration, without using a chattering vibration preventing retainer, that performs the following: (A) preparing a material having much stock for obtaining a thin-walled material, (B) while rotating the material about a center axis, cutting the inner round surface of the material within a predetermined range by feeding a cutting tool relative to material by the desired distance from one end side to the other end side of the material along the center axis, (C) while rotating the material about the center axis, cutting the outer round surface of the material within a predetermined range by feeding the cutting tool relative to the material by the desired distance from the one end side to the other end side of the material along the center axis, and (D) alternately repeating (B) and (C) to finish cutting the material.
    • 提供了一种方法来切割薄壁构件而不产生震动振动,而不使用振动防震保持器,其执行以下操作:(A)制备具有很多储备以获得薄壁材料的材料,(B)同时 使材料围绕中心轴线旋转,通过沿着中心轴线将相对于材料的切割工具相对于材料的一个端侧向另一端侧馈送期望的距离,将材料的内圆面切割在预定范围内( C)当围绕中心轴线旋转材料时,通过将切割工具相对于材料沿材料的一端侧到另一端侧的期望距离进给,将材料的外圆表面切割在预定范围内 中心轴,(D)交替重复(B)和(C)切割材料。

    • An electric compressor capable of following temperature changes of a power element even if a temperature measurement unit is disposed separately from the power element. In the electric compressor, the temperature measurement unit (34) measures the temperature of a substrate (36) on which the power element (31) is disposed. A rotational speed detection unit (35) detects the rotational speed of a motor. A control unit (33) estimates the temperature of the power element (31) on the basis of the rotational speed of the motor detected by the rotational speed detection unit (35) and the temperature measured by the temperature measurement unit (34).
    • 即使温度测量单元与功率元件分开设置,也能够跟随功率元件的温度变化。 在电动压缩机中,温度测量单元(34)测量设置有功率元件(31)的基板(36)的温度。 转速检测单元(35)检测电动机的转速。 控制单元(33)基于由转速检测单元(35)检测的电动机的转速和由温度测量单元(34)测量的温度来估计功率元件(31)的温度。
