    • A hermetic compressor capable of preventing malfunction due to impurities trapped between contact portions of a crankshaft and a crankshaft supporting frame when the crankshaft rotates in a hollow portion of the frame. The hermetic compressor comprises the frame having the hollow portion, the crankshaft rotatably inserted in the hollow portion, a balance weight provided at one end of the crankshaft, and a thrust portion formed at the frame to support the crankshaft. An impurities discharge passage is formed at an outer circumferential surface of the crankshaft that comes into frictional contact with the thrust portion of the frame to guide impurities, mixed with the oil, out of the crankshaft. Correspondingly, a plurality of discharge guiding grooves is formed at the thrust portion of the frame to guide the oil and the impurities, having passed through the impurities discharge passage of the crankshaft, out of the thrust portion.
    • 一种封闭式压缩机,其能够防止当曲轴在框架的中空部分中旋转时由于夹在曲轴的接触部分和曲轴支撑框架之间的杂质引起的故障。 封闭式压缩机包括具有中空部分的框架,可旋转地插入中空部分中的曲轴,设置在曲轴一端的平衡重,以及形成在框架处以支撑曲轴的止推部分。 在与框架的推力部摩擦接触的曲轴的外周面形成有杂质排出通道,以将与油混合的杂质引导出曲轴。 相应地,在框架的推力部分处形成有多个排出引导槽,以将已经通过曲轴的杂质排出通道的油和杂质引导出推力部分。

    • The present invention relates to a plasma display apparatus, and more particularly, to a plasma display apparatus and driving method thereof, wherein a sustain waveform can be improved. According to the present invention, the plasma display apparatus includes a plasma display panel comprising a plurality of sustain electrode pairs wherein each of the sustain electrode pairs has a scan electrode and a sustain electrode, and a sustain waveform controller for controlling a rising time or a falling time of sustain waveforms supplied to at least one of the sustain electrode pairs according to a temperature of the plasma display panel. The sustain waveform controller controls a time corresponding to a time point at which a sustain discharge is generated, of the rising time and the falling time. The present invention improves a plasma display apparatus and driving method thereof. Accordingly, there is an effect in that erroneous discharge depending on a temperature of a plasma display panel can be prevented.
    • 等离子体显示装置及其驱动方法技术领域本发明涉及等离子体显示装置,更具体地,涉及一种能够提高维持波形的等离子体显示装置及其驱动方法。 根据本发明,等离子体显示装置包括等离子体显示面板,其包括多个维持电极对,其中每个维持电极对具有扫描电极和维持电极,以及维持波形控制器,用于控制上升时间或 根据等离子体显示面板的温度,提供给至少一个维持电极对的维持波形的下降时间。 维持波形控制器控制与产生维持放电的时间点对应的时间,上升时间和下降时间。 本发明改进了等离子体显示装置及其驱动方法。 因此,可以防止根据等离子体显示面板的温度的错误放电的效果。
