Abstract: PURPOSE:To obtain a large-screen liquid crystal display device which has inconspicuous join parts by coupling plural liquid crystal display panels where a liquid crystal layer made of polymer dispersed type liquid crystal is sandwiched between substrates. CONSTITUTION:The liquid crystal display panels 1 which are constituted by sandwiching the liquid crystal layer 8 made of polymer dispersed type liquid crystal between two substrates 2 and 6 so that transparent electrodes face each other and have no seal parts at the outer peripheral parts of the substrates are coupled. The polymer dispersed liquid crystal is a gathering of liquid crystal dispersed in a polymer matrix. Nematic liquid crystal, smectic liquid crystal, etc., are used as the liquid crystal. Each liquid crystal display panel 1 is adhered to a protection cover provided on the front surface with an adhesive. In another way, the panels are fixed to transparent housings with an adhesive by utilizing non-display parts between the liquid crystal display panels and the housings are coupled. Thus, the large-screen liquid crystal display device which has inconspicuous join parts is obtained.

Abstract: PURPOSE:To eliminate generation of wrinkles, breakage, and holding of bubbles while a battery is fabricated to efficiently manufacture the battery having steady performance by impregnating a separator with a liquefied mixture containing a monomer capable of polymerizing, by stacking the separator on both sides of one electrode plate before polymerization for gelling, and by stacking the other electrode plate thereon, then by winding them. CONSTITUTION:A microporous resin film for separator is impregnated with a liquified mixture which contains a lithium ion and a material capable of polymerizing for gelling. The impregnated resin films are stacked on both sides of one electrode plate, then the material is polymerized for gelling. Since the surface of the resin film is sticky, adhesion between the electrode plate and the separator film is increased and troubles such as generation of wrinkles in the microporous resin film in wrapping process are decreased compared with use of the conventional microporous film having no gelled material. Since the liquified mixture is impregnated before polymerization, it is easily penetrated into the separator, inside pores are decreased, and internal resistance is also decreased.

The by-produced ammonium iodide is decomposed with nitrogen dioxide to recover iodine. The iodination reaction proceeds easily at room temperature - 150 deg.C, and the reaction temperature is preferably 40-90 deg.C. The amount of nitrogen dioxide is >=1mol, preferably 1.5-2.5mol per 1mol of iodine. Iodine can be nearly quantitatively recovered and reused by the iodine recovering process.

Abstract: PURPOSE:To obtain the titled compound economically and advantageously in high selectivity, by reacting an aromatic iodine compound with nitrogen dioxide under mild conditions. CONSTITUTION:An aromatic iodine compound, e.g. mono- and diiodinated compound of an alkylbenzene, is reacted with nitrogen dioxide in a solvent, e.g. acetic acid or dichloromethane, at -10-+100 deg.C, preferably 0-60 deg.C to substitute the iodine ions with the nitrogen dioxide ions and give the aimed substance in the manner of position selectivity. The nitrogen dioxide to be used as an oxidizing agent may be accompanied by nitrogen and air, etc. and continuously fed to the reaction system or dissolved in a reaction solvent and dropped with time. The molar amount of the nitrogen dioxide to be used is 2-100 times, preferably 5-50 times of that of the aromatic iodine compound.
