摘要： An active-matrix LCD causes no cross-talk even if the capacitance between a given cell and adjacent data lines is large. The LCD has a liquid crystal panel which has data lines arranged in parallel with one another, scan lines arranged orthogonally to the data lines, and liquid crystal cells arranged at the intersections of the data and scan lines, respectively. Each of the cells has a cell electrode and a switching device that is arranged between and connected to the cell electrode and a corresponding one of the data lines. The conduction of the switching device is controlled in response to a scan pulse applied to a corresponding one of the scan lines. The LCD also has a data driver for applying data signals to the data lines, respectively, so that the data signals are written to corresponding ones of the cells, and a scan driver for applying the scan pulse sequentially to the scan lines. The data driver applies positive and negative signals that are opposite to each other with respect to a reference level, to each of the data lines within the period of the scan pulse, to zero an effective voltage applied to each data line. As a result, a voltage sustained by any cell to which data has been written is not affected by voltages successively applied to a data line to which the cell is connected and a data line to which the cell is capacitively connected.

摘要： In a driver circuit of direct drive matrix type LCD panel, a quantity of ON-STATE cells (or OFF-STATE cells) displayed on the just previous scan electrode is counted and a quantity of ON-STATE cells (or OFF-STATE cells) to be displayed on a present scan electrode is also counted. A compensation voltage is generated according to a predetermined relation based on a difference of the two above-counted quantities, and is superposed onto drive voltages of unselected scan electrodes or of each of data electrodes, in a polarity that an undesirable spike voltage induced on unselected cell voltage is cancelled, in synchronization with selection of the present scan electrode. The compensation voltage may be generated according to a digital difference of the two quantities or to a change in an analog voltage representing the counted quantity. The above-described relation of the compensation voltage versus the counted quantity difference may be proportional or may be given with a predetermined specific relation to meet the panel characteristics. The compensation voltage may be a flat voltage during the period for selecting the single scan electrode or may be of a spike waveform. Amplitude of this spike is determined by the above-described predetermined relation. An irregular panel brightness caused from spike voltages induced from data electrode voltage application is cancelled.
摘要翻译：在直接驱动矩阵型LCD面板的驱动电路中，对刚刚扫描电极上显示的一定数量的ON状态单元（或OFF状态单元）进行计数，并将ON状态单元（或OFF-STATE单元）也显示在当前扫描电极上。基于两个上述计数量的差异，根据预定关系产生补偿电压，并以非选择的扫描电极或每个数据电极的驱动电压叠加在非选择的不期望的尖峰电压的极性与当前扫描电极的选择同步地消除电池电压。补偿电压可以根据两个数量的数字差或与表示计数量的模拟电压的变化产生。补偿电压与计数量差的上述关系可以是成比例的或者可以以预定的特定关系给出以满足面板特性。在用于选择单个扫描电极的周期期间，补偿电压可以是平坦的电压，或者可以是尖峰波形。该尖峰的幅度由上述预定关系决定。由数据电极电压施加引起的尖峰电压导致的不规则面板亮度被取消。

摘要： A shock absorber in which a flow of hydraulic oil caused by sliding movement of a piston in a cylinder is controlled by a pilot type main valve and a pilot valve to generate damping force. The valve-opening operation of the main valve is controlled by adjusting the pressure in a pilot chamber with the pilot valve. A valve block and a solenoid block are connected together into one unit and inserted into a casing before being secured with a nut. At this time, an actuating rod of the solenoid block is engaged with a pilot valve member retained by a pilot spring and a fail-safe spring in a cylindrical portion of a pilot body of the valve block.
