摘要:
The present invention is directed to providing a pressure-sensitive adhesive with good initial tack and good adhesion at low temperature. Generally, the pressure-sensitive adhesive composition comprises (1) a carboxylic group-containing (meth)acrylic tacky polymer having a weight average molecular weight of less than 800,000 and a glass transition temperature of −100° C. to −30° C., and (2) an amino group-containing (meth)acrylic non-tacky polymer having a weight average molecular weight of from 30,000 to 100,000 and a glass transition temperature of 20° C. to 90° C. The amino group-containing (meth)acrylic non-tacky polymer (2) is present in an amount of no less than 1 parts by mass and less than 20 parts by mass on a basis of 100 parts by mass of said carboxylic group-containing (meth)acrylic tacky polymer (1).

A liquid crystal display is provided which is capable of reducing the occurrence of defective display due to variations in the initial alignment direction of a liquid crystal alignment control film in a liquid crystal display of an IPS scheme, realizing the stable liquid crystal alignment, providing excellent mass productivity, and having high image quality with a higher contrast ratio. The liquid crystal display has a liquid crystal layer disposed between a pair of substrates, at least one of the substrates being transparent, and an alignment control film formed between the liquid crystal layer and the substrate. At least one of the alignment control films comprises photoreactive polyimide and/or polyamic acid provided with an alignment control ability by irradiation of substantially linearly polarized light.
摘要:
A film dispenser for applying an adhesive film to an elongated structure has a mounting frame, guide members on the bottom portions of the mounting frame sides to engage the shoulder portions of the elongated structure to allow movement of the apparatus in relation to the elongated structure while the guide members remains engaged with the shoulder portions, and roll mounting assembly for securely receiving a film roll near the top leading end of the apparatus. When the guide members are engaged to the shoulder portions of the elongated structure, an end of the adhesive film is applied onto the surface of the elongated structure, the apparatus is then slid to dispatch more adhesive film with controlled and consistent lateral positioning in relation to the surface of the elongated structure.

There is provided a method of producing an active material of a positive electrode used for an alkaline secondary battery which is difficult to be oxidized, and high in its reactivity with an alkaline electrolyte to form a cobalt electric conductive matrix improved in electric conductivity. The method of producing thereof is characterized in that nickel hydroxide powder is dispersed in an aqueous solution of a strongly acidic cobalt salt and the dispersed solution thereof is, while being stirred, added gradually with an aqueous alkali solution to made to react one with another to precipitate a cobalt hydroxide while maintaining the reaction solution in the region of acidity to neutrality, and a solid part in which the cobalt hydroxide is mixed in the nickel hydroxide is separated from the reaction solution which is in the region of acidity to neutrality after the completion of the reaction, and is then washed with water. By this method of producing, there is obtained an active material of a positive electrode used for an alkaline secondary battery in which the amorphous to microcrystal cobalt hydroxide is mixed in the nickel hydroxide. Thus, using this active material of the positive electrode, a paste-type nickel electrode improved in utilization rate is obtained, and using the nickel electrode, an alkaline storage battery which has a high capacity and is excellent in the battery characteristics such as discharging characteristics, etc. is obtained.
摘要:
An adhesive sheet is disclosed including a flexible substrate (4), and an adhesive layer (20) formed on at least one of the main surfaces of the flexible substrate and containing elastic microspheres (3), in which the adhesive layer has a) an elastic microsphere layer which is in contact with the main surface of the flexible substrate, comprising elastic microspheres (3) and a tacky polymer (2) and has projections containing said elastic microspheres on a surface which is not in contact with said substrate, and b) a layer of tacky polymer (1) which covers the projections containing the elastic microspheres so that raised portions are formed on an adhesion surface (11). Bubbles of air can then escape during application and use because the adhesion surface has a contact area percentage in the range between 20 and 90%. A method of making the adhesive sheet is also disclosed.

A pleochroic color display device is provided which comprises a layer of guest-host type liquid crystal sandwiched between two transparent electrodes for driving the liquid crystal, the guest-host liquid crystal containing a dichroic dye as guest material, and a color filter disposed in front or rear of the layer of the guest-host type liquid crystal. High contrast pleochroic color displays can be obtained by selecting a blackish dye as the dichroic dye. Dichroic displays other than white ones can be produced by the use of a single liquid crystal cell and a single color filter (with one color).
