    • There is provided a method for liquid mixing supply fabricating a mixed etching solution in which sulfuric acid, hydrogen peroxide, ultra pure water and hydrofluoric act are mixed together. The method includes: supplying a specific liquid chemical to a mixing tank such that it is mixed in ppm units; and supplying at least two liquid chemicals and a ultra pure water to the mixing tank at a predetermined ratio, and mixing them, wherein starting points of supplying the at least two liquid chemicals and the ultra pure water are different from each other. Since the starting points of supplying the sulfuric acid, the hydrogen peroxide, and the ultra pure water are different, it is possible to minimize the heat generation due to the reaction between the sulfuric acid with the hydrogen peroxide.
    • 提供了制造混合蚀刻溶液的液体混合供给方法,其中将硫酸,过氧化氢,超纯水和氢氟酸作用混合在一起。 该方法包括:向混合罐供应特定的液体化学品,使其以ppm为单位混合; 并以预定的比例将至少两种液体化学品和超纯水供应到混合罐中,并将它们混合,其中供应至少两种液体化学品和超纯水的起始点彼此不同。 由于提供硫酸,过氧化氢和超纯水的起点不同,因此可以使由硫酸与过氧化氢反应产生的热量最小化。

    • A drive motor for an electric vehicle includes a cylindrical housing, a cylindrical stator disposed within the housing, a coil wound around the stator, a rotor disposed within the stator, and front and rear covers respectively coupled on front and rear ends of the housing. The housing includes a cylindrical coolant passage concentrically formed around the stator in the housing, and the front or rear cover includes a coolant inlet port through which coolant is fed to the coolant passage and a coolant outlet port through which coolant circulated the coolant passage is exhausted.
    • 一种用于电动车辆的驱动电动机包括圆柱形壳体,设置在壳体内的圆柱形定子,缠绕在定子上的线圈,设置在定子内的转子以及分别联接在壳体的前端和后端上的前后盖。 壳体包括围绕壳体中的定子同心地形成的圆柱形冷却剂通道,并且前盖或后盖包括冷却剂入口,冷却剂通过所述冷却剂入口供给到冷却剂通道和冷却剂循环冷却剂通道的冷却剂出口 。
