    • A drive signal generation circuit which performs gradation control on a load by a drive signal having a stepped waveform. In a case where the wave height value corresponding to input gradation data is Vm (2≦m≦n), the drive signal is caused to rise in such a manner that each output Vk (2≦k≦m) is produced one slot after the output V(k−1) to increase the wave height value V0 (reference potential) to Vm in a stepping manner. One slot corresponds to a unit time of the pulse width modulation. The drive signal is caused to fall in such a manner that each output V(k−1) (1≦k≦m−1) is produced one or two slots after the output Vk to reduce the wave height value from Vm to off level in a stepping manner. A delay circuit is used to delay signals slot by slot. A selection is made from delayed signals according to luminance data to determine a waveform. The circuit is also designed to enable the drive signal waveform rise position to be changed.
    • 一种驱动信号生成电路,其通过具有阶梯式波形的驱动信号对负载进行灰度控制。 在与输入灰度数据对应的波高值为Vm(2 <= m <= n)的情况下,使驱动信号上升,使得输出Vk(2≤k≤m)为 在输出V(k-1)之后产生一个时隙,以逐步的方式将波高值V 0(参考电位)增加到Vm。 一个时隙对应于脉宽调制的单位时间。 使驱动信号以这样的方式下降,使得在输出Vk之后产生一个或两个时隙的每个输出V(k-1)(1 <= k <= m-1),以将波高值从Vm减小到 关闭级别。 延迟电路用于逐个时隙延迟信号。 根据亮度数据从延迟信号中进行选择,以确定波形。 该电路还被设计为使得驱动信号波形上升位置能够被改变。

    • A wire showing satisfactory electrical insulation, mechanical strength, wear resistance, crosslinking properties and appearance may be obtained by coating a conductor with an ethylene/&agr;-olefin copolymer whose density, melt flow rate, decane soluble matter content, melting point and melt tension are controlled to particular ranges. The copolymer may be used singly or in combination with high-pressure low-density polyethylene. Such copolymer provides a coated layer showing tensile strength of not less than 15 MPa, tensile elongation of not less than 400% and taper wear amount of not more than 15 mg. Furthermore, if the resin pressure in the extruder is adjusted to a particular range, high-speed extrusion becomes possible with a smooth apparent coated layer.

    • A channel-switching valve is provided. The channel-switching valve comprises: a cylindrical valve housing whose one end is closed by a main valve seat; a low pressure outlet and two connecting holes for connecting the inside and the outside of the valve housing; a high pressure inlet for connecting the inside and the outside of the valve housing; and a connecting groove and a guide groove formed on an end surface of a main vale element which is accommodated in the valve housing. When the main valve element is situated in a first rotation position, one of the connecting holes is connected to the low pressure outlet by the connecting groove while the other one of the connecting holes is connected to the high pressure inlet. When the main valve element is situated in a second rotation position, the other one of the connecting holes is connected to the low pressure outlet by the connecting groove while the one of the connecting holes is connected to the high pressure inlet by the guide groove.Both end surfaces of the main valve element are externally connected by an equalizer channel formed inside the valve housing. When the main valve element is rotated between the first rotation position and the second rotation position by a main valve element drive, the lower end surface of the main valve element is separated from the main valve seat by internally connecting both end surfaces by a pilot port which is open as a pilot valve element is moved by a pilot valve element drive.
