    • Color layers of a color filter obtained by exposing a transparent substrate to light from the back side followed by development may have a defect of layer unflatness produced due to unevenness caused by contamination with foreign matters. The defect can be repaired by eliminating the defective part of the color layers to produce a blank there, optionally filling the blank with a negative photosensitive composition containing a black colorant and returning the thus modified color filter to an appropriate step in the production line. The color filter repaired is used to fablicate multi-color display devices which are by no means inferior in display qualities to those fablicated using a color filter having no defect originally.
    • 通过将透明基板从背面曝光并随后显影而获得的滤色器的彩色层可能具有由于异物污染引起的不均匀性而产生的层不平坦的缺陷。 可以通过消除彩色层的有缺陷的部分以在其中产生空白来修复缺陷,可选地用含有黑色着色剂的负型感光性组合物填充坯料,并将经过修改的滤色器返回到生产线中的适当步骤。 维修的彩色滤光片用于制作多色显示装置,这些显示装置的显示质量与使用最初没有缺陷的滤色片制成的显示器质量相差甚远。

    • In a phased-array antenna apparatus of this invention, one of the transmit/receive modules of each of radiators is set in a receiving operation state in accordance with a control signal from an arithmetic processing unit. An RF reference signal from an exciter is radiated in the air from a reference antenna and received by the transmit/receive modules in the receiving operation state. Thereafter, the signals are frequency-converted by the receiver, and element data are extracted from the signals by a beam forming section. The arithmetic processing unit detects the phase and amplitude data of the reception signals from the transmit/receive modules on the basis of the element data, and compares the detected data with the past phase and amplitude data of the transmit/receive modules, thereby calculating correction data and weight data for the transmit/receive modules.
    • 在本发明的相控阵天线装置中,根据来自运算处理单元的控制信号将每个辐射器的发射/接收模块之一设置在接收操作状态。 来自激励器的RF参考信号在空中从参考天线辐射并在接收操作状态下由发射/接收模块接收。 此后,信号被接收机频率转换,并且通过波束形成部分从信号中提取元素数据。 算术处理单元根据元件数据检测来自发送/接收模块的接收信号的相位和振幅数据,并将检测到的数据与发送/接收模块的过去相位和振幅数据进行比较,由此计算校正 发送/接收模块的数据和权重数据。

    • There is provided a radar apparatus wherein a local signal having a coherent sine wave is modulated to generate a composite signal of two signals modulated by different modulation functions. The composite signal is transmitted as a transmission signal, and a reception signal associated with the transmitted signal is separated into two signal components modulated by the different modulation functions. A difference between the two signal components is found, thereby removing a reflection signal from a static clutter and extracting a signal component which has been frequency-deviated by a moving target. Thus, the moving target is displayed. The transmission frequency can be quickly changed without losing the function of detecting the moving target.
