    • A matrix liquid crystal display device provided with switching transistors, made of amorphous silicon thin-film for example, which are connected to each display picture element. The switching transistors are scanned with a scan pulse having width H which is set at a value greater than that is expressed by T/N, where H denotes the scan pulse width applied to row electrodes connected to each gate of the switching transistor, T denotes the total scan time and N the number of the scan lines. Concretely, the timewise width of the scan pulses is expanded or the number of applicable scan pulses is increased. The preferred embodiments relate to such a liquid crystal display driving system that can effectively minimize the decline of the voltage and the display characteristics caused by insufficient charge against the display picture element electrodes via the switching transistors. In particular, the driving method embodied by the present invention is extremely useful for driving a large-capacity X-Y matrix liquid crystal display device.
    • 一种矩阵液晶显示装置,其设置有例如与各显示图像元素连接的由非晶硅薄膜构成的开关晶体管。 用宽度为H的扫描脉冲扫描开关晶体管,该扫描脉冲设定为大于由T / N表示的值,其中H表示施加到连接到开关晶体管的每个栅极的行电极的扫描脉冲宽度,T表示 总扫描时间和N个扫描线数。 具体地,扫描脉冲的时间宽度被扩大或适用的扫描脉冲的数量增加。 优选实施例涉及这样的液晶显示驱动系统,其可以有效地最小化通过开关晶体管对显示图像元素电极的电荷不足引起的电压下降和显示特性的降低。 特别地,本发明具体实施的驱动方法对于驱动大容量X-Y矩阵型液晶显示装置非常有用。

    • A mechanism for attenuating torsional vibration in a compressor is described. The compressor includes a swash plate secured to a drive shaft and pistons coupled to the swash plate. Compression of refrigerant gas by the pistons generates torsional vibrations of the drive shaft. The rear end of the drive shaft is coupled to a damper for attenuating torsional vibrations. The damper includes a frictional plate secured to the rear end of the drive shaft, a weight rotatably fitted about the drive shaft, and a coil spring. The coil spring elastically presses the weight against the frictional plate and elastically couples the weight with the drive shaft. When the drive shaft torsionally vibrates, the weight contacts the frictional plate and is vibrated about the axis of the drive shaft by the coil spring. As a result, energy of the torsional vibrations is consumed and the vibrations are attenuated. Further embodiments show similar dampers attached to the exterior of the compressor.
    • 描述了用于衰减压缩机中的扭转振动的机构。 压缩机包括固定到驱动轴的旋转斜盘和联接到斜盘的活塞。 活塞对制冷剂气体的压缩产生驱动轴的扭转振动。 驱动轴的后端连接到用于衰减扭转振动的阻尼器。 阻尼器包括固定到驱动轴的后端的摩擦板,围绕驱动轴可旋转地配合的重量和螺旋弹簧。 螺旋弹簧将重物弹性地压在摩擦板上并将重物与驱动轴弹性连接。 当驱动轴扭转时,重物接触摩擦板,并通过螺旋弹簧绕驱动轴的轴线振动。 结果,扭转振动的能量被消耗并且振动被衰减。 另外的实施例示出了附接到压缩机外部的类似的阻尼器。
