    • The present invention provides a 2 stage rotary compressor (100) including a hermetic container (101), a 2 stage compression assembly provided in the hermetic container, wherein a low pressure compression assembly (120), a middle plate (130) and a high pressure compression assembly (140) are successively stacked from any one of upper and lower portions, a first discharge port (124) for discharging middle pressure refrigerant compressed in the low pressure compression assembly (120) a second discharge port (162p) for discharging high pressure refrigerant compressed in the high pressure compression assembly (130) and a third discharge port (172p) positioned at any one of the upper and lower portions of the 2 stage compression assembly to discharge high pressure refrigerant compressed in the 2 stage compression assembly to the hermetic container (101), wherein an area of the third discharge port (172p) is larger than 0.5 times of an area of the first discharge port and smaller than 1.0 times thereof. As a volume flow of refrigerant compressed in the low pressure compression assembly (120) determines a volume flow of refrigerant compressed in the entire 2 stage compression assembly, a size of the third discharge port discharging refrigerant compressed in the 2 stage compression assembly is preferably optimized at a ratio with respect to a size of the first discharge port (127). Therefore, the size of the third discharge port (172p) can be optimized to suppress noise of the compressor.
    • 本发明提供一种二级旋转压缩机(100),其包括密封容器(101),设置在密封容器中的二级压缩组件,其中低压压缩组件(120),中间板(130)和高 高压压缩组件(140)从上部和下部中的任一个连续堆叠,用于排出在低压压缩组件(120)中压缩的中压制冷剂的第一排出口(124),用于排出高压的第二排出口(162p) 在高压压缩组件130中被压缩的压力制冷剂和位于二级压缩组件的上部和下部中的任何一个的第三排出口(172p),以将在2级压缩组件中压缩的高压制冷剂排放到 密封容器(101),其中第三排出口(172p)的面积大于第一排出口的面积的0.5倍,小于1.0TI 其中。 由于在低压压缩组件(120)中压缩的制冷剂的体积流量决定了在整个2级压缩组件中压缩的制冷剂的体积流量,所以优选排出在2级压缩组件中压缩的制冷剂的第三排出口的尺寸 相对于第一排出口(127)的尺寸的比例。 因此,可以优化第三排出口(172p)的尺寸,以抑制压缩机的噪音。

    • Methods of fabricating a memory device can include forming a plurality of wordlines on a semiconductor substrate. A ground select line can be formed on a first side of the wordlines. A string select line can be formed on a second side of the wordlines. The wordlines can extend between the ground select line and the string select line. First spacers may be formed between the wordlines, between the ground select line and an adjacent one of the wordlines and between the string select line and an adjacent one of the wordlines. Second spacers can be formed on sidewalls of the ground select line and the string select line displaced from the first spacers. The second spacers can be formed from a different material than the first spacers.
    • 制造存储器件的方法可以包括在半导体衬底上形成多个字线。 地线选择线可以形成在字线的第一面上。 字线选择线可以形成在字线的第二侧上。 字线可以在接地选择线和字符串选择行之间延伸。 第一间隔物可以形成在字线之间,地线选择线与字线之间的相邻字符之间以及字符串选择线和字线之间的相邻字线之间。 第二间隔件可以形成在地选线的侧壁和从第一间隔件移位的串选择线。 第二间隔件可以由与第一间隔物不同的材料形成。
