    • Disclosed herein is a horizontal type orbiting vane compressor having a horizontal structure. The horizontal type orbiting vane compressor comprises a horizontally disposed shell having an inlet tube and an outlet tube, a compression unit disposed in the shell at one side of a horizontally disposed rotary shaft such that the compression unit is rotated by a drive unit for compressing refrigerant gas, and an oil-supplying unit for supplying oil from an oil sump to an oil hole extending through the rotary shaft by an orbiting movement of an orbiting vane in the compression unit. When the horizontal type orbiting vane compressor is applied to an air conditioner, an outdoor unit of the air conditioner is greatly reduced in size.

    • Disclosed herein is an oil supply structure for a slider of an orbiting vane compressor capable of providing effective lubrication to reciprocating surfaces of the slider reciprocating in an annular space of a compressor cylinder. The oil supply structure comprises an oil supply slot formed at an upper surface of an inner ring provided in the cylinder to supply oil to outer surfaces of the slider, and oil grooves formed at the outer surfaces of the slider to guide the oil, supplied through the oil supply slot, along the outer surfaces of the slider. The oil supply structure achieves effective lubrication of the reciprocating surfaces of the slider to thereby reduce friction between the slider and the cylinder, resulting in improved compressor performance.
    • 本文公开了一种用于轨道式叶片压缩机的滑块的供油结构,其能够为在压缩机气缸的环形空间中往复运动的滑块的往复运动表面提供有效的润滑。 供油结构包括:供给槽,其形成在设置在气缸中的内环的上表面,以将油供给到滑块的外表面;以及油槽,其形成在滑块的外表面处以引导油,通过 供油槽沿着滑块的外表面。 供油结构实现滑块往复运动表面的有效润滑,从而减小滑块与气缸之间的摩擦,从而提高压缩机的性能。

    • A method for detecting a text region in an image is disclosed. The method includes detecting a candidate text region from an input image. A set of oriented gradient images is generated from the candidate text region, and one or more detection window images of the candidate text region are captured. A sum of oriented gradients is then calculated for a region in one of the oriented gradient images. It is classified whether each detection window image contains text by comparing the associated sum of oriented gradients and a threshold. Based on the classifications of the detection window images, it is determined whether the candidate text region is a true text region.
    • 公开了一种用于检测图像中的文本区域的方法。 该方法包括从输入图像中检测候选文本区域。 从候选文本区域生成一组定向梯度图像,并且捕获候选文本区域的一个或多个检测窗口图像。 然后针对一个定向梯度图像中的区域计算定向梯度的总和。 通过比较相关联的归一化梯度和阈值来分类每个检测窗口图像是否包含文本。 基于检测窗口图像的分类,确定候选文本区域是否是真实文本区域。
