摘要： This invention relates to a liquid crystal display element comprising a pair of transparent substrates, electrodes formed on the individual surfaces thereof facing each other, a liquid crystal material layer held between the substrates, and gap controlling material for keeping the gap between the substrates, and is characterized in that the gap controlling material is dispersed and fixed on the substrate surface by an insulating coating film such as an orientation controlling film.When the gap controlling material is thus dispersed and fixed, it does not move between the substrates, and hence the change of the gap length between the substrates is prevented, so that there can be obtained a liquid crystal display element in which the distance between the substrates is uniform. Moreover, when the insulating coating film is an orientation controlling film, the dispersion and fixation of the gap controlling material is completed simultaneously with the formation of the orientation controlling film, so that beneficial effect can be obtained also with respect to working efficiency.When the gap controlling material is a combination of a polymer solid and an insulating material having a higher softening point and regidity than those of the polymer solid, the uniformalization and change prevention of the gap length are more effectively achieved.
摘要翻译：本发明涉及一种液晶显示元件，包括一对透明基板，形成在彼此面对的各个表面上的电极，保持在基板之间的液晶材料层和用于保持基板之间的间隙的间隙控制材料，以及其特征在于，间隙控制材料通过诸如取向控制膜的绝缘涂膜分散并固定在基板表面上。当间隙控制材料因此被分散和固定时，其不会在基板之间移动，因此防止了基板之间的间隙长度的变化，从而可以获得液晶显示元件，其中，基材均匀。此外，当绝缘涂膜是取向控制膜时，与形成取向控制膜同时完成间隙控制材料的分散和固定，从而在工作效率方面也可获得有益的效果。当间隙控制材料是聚合物固体和具有比聚合物固体高的软化点和反应性的绝缘材料的组合时，更有效地实现了间隙长度的均匀化和防止变化。

摘要： A transfer apparatus for electrophotography is disclosed in which the resistance values of a transfer belt and the recording paper are measured, and the current value applied to a device for charging a member is set on the basis of the electrical resistance values. The charging device of the transfer belt is adapted to be taken up and reeled out and to circulate along a track. This configuration assures a stable transfer characteristic against the secular environmental variations of the component elements, lengthens the intervals of replacement of the charged member, and hence increases the mechanical life of the transfer apparatus and the electrophotographic apparatus using the same.
