摘要： PURPOSE:To obtain the guest-host type liquid crystal display device which is bright and has a large contrast ratio by sealing a guest-host type liquid crystal which contains the styryl or the like compd. expressed by the specific general formula as a guest and has an electron acceptive substituent as a host between two sheets of substrates. CONSTITUTION:A transparent conductive film and oriented film are formed in this order on the transparent substrate of two sheets of the substrates 1, 2 at least one of which is transparent. The conductive film and oriented film are laminated and formed in this order on the other substrate as well. The liquid crystal molecules 5 having the electron acceptive substituent and the styryl or the like compd. 6 expressed by the general formula [I] are sealed between two sheets of the substrates 1 and 2. The liquid crystal molecules 5 are oriented again in the electric field direction if the sealed liquid crystal mixture system is first homeotropically oriented and when the electric field is impressed between the electrodes from a power source 7. The styryl or the like compd. 6 in the color developed state is also oriented again in the same direction in this way and a change is generated in the absorptivity. The positive display with the good contrast and responsiveness is thus executed.

摘要： PURPOSE:To largely change reflectivity and to obtain reflected light which is colored by sealing a guest-host type liquid crystal contg. the styryl dye expressed by the specific general formula as a guest between a transparent electrode substrate having a transparent conductive film and oriented film and a reflecting electrode substrate having a metallic film and oriented film. CONSTITUTION:An ITO film 5 and the oriented insulating film 6 are successively laminated and formed on the glass substrate 4 and an aluminum film 8 and the oriented insulating film 7 are successively laminated and formed on the glass substrate 9. The guest-host type liquid crystal 3 contg. the styryl dye expressed by the general formula (I) is sealed between these two substrates. The liquid crystal molecules attain the perpendicular orientation as the initial orientation state at the non-antidazzle time (when a voltage is not impressed) and, therefore, the light from the front face transmitted through the liquid crystal 3 is the colorless reflected light. The liquid crystal molecules are horizontal at the antidazzle time (when the voltage is impressed) and, therefore, the light from the front face passes the dye molecules made horizontal by the guest-host effect and becomes the reflected light which is colored. The dazzle prevention is thus executed. The reflectivity is largely changed by changing the impressed voltage.

摘要： PURPOSE:To provide the titled superconductor having high critical temperature and high stability with time and composed of a sintered material containing an oxide of (rare-earth element)-Al-O and an oxide of (alkaline-earth metal)-(rare-earth element)-Co-O at a specific molar ratio. CONSTITUTION:The objective ceramic superconductor is composed of a sintered material containing an oxide expressed by the chemical formula LnAlO3 (Ln is Bi, Y or lanthanide rare-earth element) and an oxide of formula Me0.5Ln0.5 CoO3 (Me is Ca, Sr or Ba) at a molar ratio of 1:2. The superconductor can be produced e.g. by weighing raw materials such as La(NO3)3, Al(NO3)3, Me(NO3)2 and Co(NO3)2 at ratios to form a composition of LaAlO3.2Me0.5La0.5 CoO3, dissolving the raw materials in water, adjusting the pH to nearly neutral state with NH4OH to precipitate hydroxide, calcining the precipitate, crushing and forming the calcination product and sintering the formed material in air.

摘要： PURPOSE:To improve the response speed to develop functions by inserting a porous poly (O-phenylene diamone) (PPD) film and electrolyte layer between two electrodes. CONSTITUTION:Micropores are bored to the PPD film by projecting electron rays or laser beam thereon or the rate of polymn. is increased to form the porous film at the time of electrolytic polymn. of the PPD film or a large molecular electrolyte is incorporated into the film and is then eluted in a solvent to form the porous film at the time of electrolytic polymn. or the molecules failing to make the polymn. reaction are captured into the film and are likewise eluted to form the porous film. The porous PPD film formed in such a manner and the electrolyte layer are inserted between the two electrodes. The response speed to develop the function of a molecular sieve, sensor, ECD, etc., is thereby increased.

摘要： PURPOSE:To obtain a display element which is stable, long in life and suitable for a thin type by providing a soln. or electrolyte packed between substrates and providing a high-polymer film having a redox active point on the surface of either display electrode or counter electrodes. CONSTITUTION:An ITO film is deposited by evaporation as the display electrode 2 on the glass substrate 1 and a WO3 film 3 is deposited by vacuum evaporation thereon in an amorphous state. On the other hand, the ITO film is deposited by vacuum evaporation on the glass substrate 4 and a thin polypyrrole film is provided by electrolytic polymn. thereon to form a functional high-polymer film 6. 1M LiCl4 and propylene carbonate electrolyte are packed as the electrolyte 7 between two sheets of such substrates and the substrates are sealed by a sealing part 8. The electrons and the cation in the electrolyte 7 are implanted to the WO3 film 3 and the film colors when a voltage is impressed between the display electrode 2 as negative electrode and the counter electrode 5. The electrons migrate at the same instant from the film 6 to the electrode 5 and the anion in the electrolyte 7 is implanted into the film 6. The thin type display element having the stability and long life is thus obtd.

摘要： PURPOSE:To improve the life and contrast of display and to facilitate multicolor display by dissolving a specified dye and I2 in a nonaqueous org. soln. contg. a supporting electrolyte and using the obtd. soln. as electrochromic soln. CONSTITUTION:A confronting display electrode and a counter electrode are provided on two substrates, at least one of the two being transparent. An electrochromic soln. prepd. by dissolving a dye expressed by the formula I (wherein R1 and R2 are same or different lower alkyl; R3 and R4 are H or alkyl; R5 is lower alkyl; Z is 0 or S; X is H, halogen, lower alkyl, alkoxy, NO2, or SO2CH3; m is 2 or 3; n is an integer 1 or 2) and I2 in a nonaqueous org. soln. contg. a supporting electrolyte, is filled between the substrates. If at least one of the substrates is transparent, the product is useful as display element. If both are transparent, the element is used in the form of light transmitting display element instead of light reflecting display element. Transparent In2O3, SnO2, or mixtures thereof are used as the material for the display electrode 2 and counter electrode 3.
