    • According to example embodiments, a nonvolatile memory device includes a first and a second NAND string. The first NAND string includes a first string selection transistor, a first local ground and a first global ground selection transistor, and first memory cells stacked in a direction perpendicular to a substrate. The second NAND string includes a second string selection transistor, a second local ground and a second global ground selection transistor, and second memory cells stacked in the direction perpendicular to the substrate. The device includes a selection line driver including path transistors configured to select and provide at least one operation voltage to the first and second string selection transistors, the first and second local and global ground selection transistors. The first and second string selection transistors are electrically isolated from each other, and the first and second global ground selection transistors are electrically connected.

    • A scroll compressor is provided, in which at least one bypass hole that bypass a portion of a refrigerant before the refrigerant is discharged through a discharge hole is formed at a position where a bypass section that bypasses the refrigerant through the at least one bypass hole overlaps a discharge section that discharges the refrigerant through the discharge hole. The at least one bypass hole is formed at a position where a wrap volume ratio (Vs/Vd), which is a ratio of a suction volume (Vs) with respect to a discharge volume (Vd) in a compression chamber, is within the range of about 1.8˜2.2. With this configuration, over-compression of refrigerant may be prevented in a low speed driving mode, and efficiency of the compressor may be enhanced in the low speed driving mode and under a low load condition.
    • 提供了一种涡旋式压缩机,其中在通过所述至少一个旁通孔旁路制冷剂的旁通部分的位置处形成有至少一个在制冷剂通过排出孔排出之前绕过制冷剂的一部分的旁通孔重叠 排出部,其通过排出孔排出制冷剂。 至少一个旁通孔形成在作为吸入容积(Vs)相对于压缩室中的排出容积(Vd)的比率的卷绕体积比(Vs / Vd)在 范围约1.8〜2.2。 利用这种结构,可以在低速驱动模式下防止制冷剂的过度压缩,并且在低速驱动模式和低负载条件下可以提高压缩机的效率。
