摘要： The liquid crystal apparatus has a segment substrate and a common substrate. Segment electrodes are formed on the segment substrate, while common electrodes are formed on the common substrate. A liquid crystal composition is sealed between the segment and common substrates with a seal member. The segment and common electrodes, the liquid crystal composition and the seal member constitute an elongated shatter portion including light shutters arranged in two rows. Liquid crystal reservoir portions are formed between the substrates and coupled to the shutter portion. The liquid crystal reservoir portions are resilient and thus can be deformed to suppress a change in the pressure applied on the liquid crystal composition due to a change in the volume of the liquid crystal composition. As a result, the formation of bubbles in the shutter portion can be prevented.

摘要： A liquid crystal apparatus has first and second liquid crystal substrates opposing each other. Segment electrodes are formed on the inner surface of the first substrate. Common electrodes are formed on the inner surface of the second substrate. Seal members seal a liquid crystal composition in a predetermined region between the segment electrodes and the common electrodes. Light shutters are formed by these electrodes and the liquid crystal composition sealed therebetween. In order to reduce influence of a hysteresis effect in the liquid crystal composition when a high frequency electric field is applied, the liquid crystal composition has a dielectric scattering phenomenon in which its dielectric anisotropy in response a low frequency electric field is larger than the absolute value of its dielectric anisotropy in response a high frequency electric field.

摘要： A temperature detection circuit and two RAMs are connected to a conversion circuit for converting image data into voltage designation signals and outputting the signals to a signal electrode driver. The temperature detection circuit detects the temperature of a liquid crystal display element as one of conditions which influence the behavior of liquid crystal molecules. One RAM is used to store a conversion table in which voltage designation signals for designating effective voltage to be applied to a liquid crystal layer are preset for image data for each predetermined temperature range of the liquid crystal display element. The other RAM is used to store input image data. In the conversion table, the number of different voltage designation signals in a high-temperature range is set to be smaller than that of different voltage designation signals in a normal temperature range. The conversion circuit reads out voltage designation signals in accordance with a detection signal from the temperature detection circuit and image data, and outputs the signals to the signal electrode driver. With this operation, effective voltages corresponding to the voltage designation signals are applied to the liquid crystal layer, and a color display with excellent perceptibility can always be obtained regardless of the temperature of the liquid crystal display element.
摘要翻译：温度检测电路和两个RAM连接到转换电路，用于将图像数据转换成电压指定信号，并将信号输出到信号电极驱动器。温度检测电路检测液晶显示元件的温度作为影响液晶分子的行为的条件之一。一个RAM用于存储转换表，其中为液晶显示元件的每个预定温度范围的图像数据预设了用于指定施加到液晶层的有效电压的电压指定信号。另一个RAM用于存储输入图像数据。在转换表中，将高温范围内的不同电压指定信号的数量设定为小于在正常温度范围内的不同电压指定信号的数量。转换电路根据来自温度检测电路的检测信号和图像数据读出电压指定信号，并将该信号输出到信号电极驱动器。通过该动作，对液晶层施加与电压指定信号对应的有效电压，无论液晶显示元件的温度如何，都能够始终获得具有良好感知性的彩色显示。

摘要： A method and apparatus for detecting through-hole voids in a multi-layer printed circuit board. The through-hole is formed with an electrical conductor for interconnecting wiring patterns of upper layers and wiring patterns of lower layers of the printed wiring board and is illuminated with a beam having a wavelength falling within a specified wavelength band capable of exciting an luminescent beam from a layer material. The layer material is exposed by a through-hole void in the through-hole of the printed wiring board. The luminescent beam excited by the illumination beam impinging upon the layer material by way of the through-hole void in the through-hole is focussed by means of a focussing optical system and a photoelectric converter. The photoelectric converter converts the luminescent beam into an electrical signal. The presence of a through-hole void is indicated by the electrical signal.
