    • Hydraulic pressure is controlled, which has such advantages that a generation of peak pressure (shoot pressure) can be lowered, mis-operation due to biting of particles can be reduced, or the cost thereof can be reduced. First, a large amount inflow command current is supplied to a proportional solenoid from a time point t1 to a time point t2. Consequentially, pilot pressure rises in a pilot pressure receiving chamber, so that a pressure control valve allows a large amount of hydraulic fluid to flow in a clutch or brake cylinder. At this time, potential detected by a pressure switch becomes zero level. Next, at the time point t2, a filling command small current is supplied to the proportional solenoid, thereby decreasing the amount of hydraulic fluid, which flows from an input port to an output port. This state is maintained from the time point t2 to a time point t3. At the termination of filling, peak pressure will not be generated, and a speed-changing shock in a clutch will not be generated, so that smooth switching can be accomplished.
    • 控制液压的优点在于能够降低峰值压力(枝条压力)的产生,能够降低由于颗粒的咬入引起的误操作,或降低其成本。 首先,从时刻t1到时刻t2向比例螺线管供给大量的流入指令电流。 因此,先导压力接收室中的先导压力上升,使得压力控制阀允许大量的液压流体在离合器或制动缸中流动。 此时,由压力开关检测到的电位变为零电平。 接下来,在时间点t2,向比例螺线管供给填充指令小电流,从而减少从输入口流向输出口的液压流体的量。 该状态从时刻t2到时刻t3保持。 在填充终止时,不会产生峰值压力,并且不会产生离合器的变速冲击,从而可以实现平滑的切换。

    • A liquid crystal display device includes a liquid crystal display panel in which pixels are arranged in rows and columns. Each of the pixels includes a pixel electrode, and a thin-film transistor having a gate electrode and a drain electrode. Gate signal lines arranged in the rows are connected to the gate electrodes of the thin-film transistors. Drain signal lines arranged in the columns are connected to the drain electrodes of the thin-film transistors. The liquid crystal display device further includes a gate drive circuit for driving the gate signal lines, and a drain drive circuit for driving the drain signal lines. The drain drive circuit receives a plurality of grey-scale reference voltages from an external circuit, interpolates a plurality of intermediate voltages between each pair of adjacent ones of the grey-scale reference voltages, selects voltages from the grey-scale reference voltages and the intermediate voltages, and applies the selected voltages to the drain signal lines. V0 is a grey-scale reference voltage corresponding to a minimum grey-scale level, Vm is a grey-scale reference voltage corresponding to a maximum grey-scale level, and Vi is a grey-scale reference voltage that is nearest to a voltage level (Vm+V0)/2. A number of intermediate voltages interpolated between V(i−1) and Vi is different from both a number of intermediate voltages interpolated between V0 and V1, and a number of intermediate voltages interpolated between V(m−1) and Vm.
