摘要:
A pressure sensor comprising an air-tight container, enclosing water vapor therein, which elastically deforms depending upon a variation in the external pressure to result in a variation in the content volume thereof, a moisture sensor disposed within the container, and a moisture detector which electrically detects a variation in the amount of moisture to be absorbed by the moisture sensor depending upon the internal partial pressure of the water in the container due to the elastic deformation of the container.

A moisture sensitive resistive element includes a substrate made of an electrically non-conductive material, first and second electrodes deposited on the substrate in a spaced relation to each other, and a moisture sensitive film deposited on the substrate covering both the first and second electrodes. The moisture sensitive film is formed by a material given by a formula: [--CH(C.sub.6 H.sub.4 SO.sub.3 X)--CH.sub.2 --].sub.n wherein X is any one of a hydrogen atom, metal atom, ammonium, urea, triethylenediamine, tetramethyleneguanidine and hexamethylenediamine, or formed by a mixture of the above material with a hydrophilic polymer which is any one selected from a group consisting of polyvinyl alcohol, methyl cellulose and polyamide resin.

Methods for forming an orientation film comprising a first step wherein a silane coupling agent is chemically adsorbed on a substrate surface, and a second step wherein an organic compound comprising a functional group capable of coupling with the silane coupling agent is coupled with the silane coupling agent. The second step includes a) applying a magnetic or electrical field in a selected direction to a mixture of 1) a liquid crystal compound being in a liquid crystal phase when heated and 2) the organic compound, b) contacting the substrate with the mixture which is in the applied magnetic or electrical field, and c) heating the mixture which is contacted with the substrate to a temperature sufficient for coupling of the silane coupling agent and the organic compound during the magnetic or electrical field application. The organic compound coupled with the silane coupling agent is directed toward a direction corresponding to the selected direction of the magnetic or electrical field.

A liquid crystal display element comprising a light transmissive substrate (#34), insulating films (#52) formed on the substrate and transparent electrodes (#5) arranged to form predetermined patterns on the insulating films. Conductive lines (#51) are conductively in contact with the transparent electrodes, and each conductive line includes a first layer (#51a) made of indium tin oxide which is adhesive to the substrates. The conductive lines are arranged between the insulating films to form a plane surface with the insulating films.

A liquid crystal display element using ferroelectric liquid crystal includes a light blocking thin film which is formed by silicon or silicon-germanium solid solution by evaporation between electrodes formed by an ITO film placed in a striped pattern on a surface of a transparent glass substrate so that the thin film does not protrude from the ITO film surface. This thin film shades a non-pixel region as a black matrix.
