    • A variable capacity rotary compressor is designed to prevent eccentric bushes from slipping during a compression operation, and thereby prevent noise from being generated and increase durability. The variable capacity rotary compressor includes a housing to define first and second compression chambers having different capacities therein. First and second eccentric cams are mounted to a rotating shaft to be placed in the first and second compression chambers, respectively. First and second eccentric bushes are rotatably fitted over the first and second eccentric cams, respectively. First and second rollers are rotatably fitted over the first and second eccentric bushes, respectively. First and second vanes partition the first and second compression chambers, respectively. A locking unit functions to make one of the first and second eccentric bushes be eccentric from the rotating shaft while making a remaining one of the first and second eccentric bushes be released from eccentricity from the rotating shaft, according to a rotating direction of the rotating shaft. A restraining unit is outwardly projected from the rotating shaft by a centrifugal force when the rotating shaft is rotated, thus restraining the first and second eccentric bushes.
    • 可变容量的旋转压缩机被设计成在压缩操作期间防止偏心衬套滑动,从而防止产生噪音并提高耐久性。 可变容量的旋转压缩机包括用于限定其中具有不同容量的第一和第二压缩室的壳体。 第一和第二偏心凸轮分别安装在旋转轴上,以分别放置在第一和第二压缩室中。 第一和第二偏心衬套分别可旋转地安装在第一和第二偏心凸轮上。 第一和第二辊分别可旋转地装配在第一和第二偏心衬套上。 第一和第二叶片分别分隔第一和第二压缩室。 锁定单元用于使第一和第二偏心衬套中的一个与旋转轴偏心,同时使第一和第二偏心衬套中的剩余的一个从旋转轴偏心地脱离,根据旋转轴的旋转方向 。 当旋转轴旋转时,限制单元通过离心力从旋转轴向外突出,从而限制第一和第二偏心衬套。

    • A variable capacity rotary compressor is designed to prevent eccentric bushes from slipping during a compression operation, thus preventing noise from being generated and increasing durability. The compressor includes a housing to define two compression chambers having different capacities therein. A rotating shaft is rotated in the compression chambers. Two eccentric cams are mounted to the rotating shaft. Two eccentric bushes are rotatably fitted over the eccentric cams. Two rollers are rotatably fitted over the eccentric bushes. Two vanes are installed in the compression chambers to be reciprocated in a radial direction of the rotating shaft. A cylindrical connecting part integrally connects the eccentric bushes to each other, with a locking slot being provided around the connecting part. A locking pin is mounted to the rotating shaft to project from the rotating shaft, and is locked by either of opposite ends of the locking slot, according to a rotating direction of the rotating shaft, thus making one of the eccentric bushes eccentric from the rotating shaft while making a remaining one of the eccentric bushes be released from eccentricity from the rotating shaft. A restraining unit outwardly moves from the rotating shaft by a centrifugal force when the rotating shaft is rotated, to restrain the connecting part.

    • A data modulation method and a data error correction method are provided. The data modulation method includes generating a channel sequence for an input sequence, determining whether or not the channel sequence violates a Run Length Limit (RLL) constraint, and performing, when the channel sequence violates the RLL constraint, bit flip at a position prior to a position at which the RLL constraint is violated among positions of bits included in the channel sequence. The data error correction method includes detecting an error bit of received data using a parity check matrix, determining whether or not the error bit is an error caused by bit flip, and correcting the error bit when the error bit is an error caused by bit flip for applying an RLL constraint.
    • 提供了数据调制方法和数据纠错方法。 数据调制方法包括产生用于输入序列的信道序列,确定信道序列是否违反运行长度限制(RLL)约束,并且当信道序列违反RLL限制时,执行比特翻转 在通道序列中包含的位的位置之间违反RLL约束的位置。 数据纠错方法包括使用奇偶校验矩阵检测接收到的数据的错误位,确定错误位是否是由位翻转引起的错误,以及当错误位是由位翻转引起的错误时校正错误位 用于应用RLL约束。
