A method of producing a polarizing film having a high polarizing function. Provided is a method of producing a polarizing film, including the steps of: at least dyeing and stretching a first polyvinyl alcohol of two or more band-like polyvinyl alcohol films in the course of a traveling path while traveling the first polyvinyl alcohol film in a longitudinal direction, and bonding a tail end of the first polyvinyl alcohol resin film to a leading end of a second polyvinyl alcohol resin film to at least dye and stretch the first and second polyvinyl alcohol resin films continuously, wherein the first and second polyvinyl alcohol resin films are arranged with the tail end of the first polyvinyl alcohol resin film and the leading end of the second polyvinyl alcohol resin film being layered, and an interface portion thereof is laser welded to perform the bonding.
摘要:
A polarizing plate of the present invention comprises: a polarizer; a transparent protective film placed on at least one side of the polarizer; and an adhesive layer interposed between the polarizer and the transparent protective film, wherein the polarizer is a stretched polyvinyl alcohol film dyed with a dichroic material and containing a sulfate ion, and the adhesive layer is formed with an active energy ray-curable adhesive containing at least one curable component. The polarizing plate has durability at high temperature.

The invention has an object to provide a connector 10 which achieves a reduced overall height of the order of 1.0 mm and space-saving substrate (in the inserting direction of a circuit board) and which obtains stable connection with a slight operating force and does not cause any defective connection even if a connecting object is accidentally subjected to an external force. The object is accomplished by a connector comprising substantially H-shaped contacts 14 each including a first piece 28 having a contact portion 32 and a pressure receiving portion 34, a second piece 30 having a contact portion 32 and a connection portion 36, and a jointing portion 38 connecting these first and second pieces, and further including holding device permitting pushing portions 48 of a pivoting member 16 to pivotally move between the pressure receiving portions 34 and the connection portions 36, a housing 12 having a ceiling portion 20 formed at least at both ends with protection walls 22 for preventing the ceiling portion 20 from being upwardly deformed when the connecting object is accidentally forced upwardly, and the pivoting member 16 including the pushing portions 48, anchoring holes 50 independently from one another and an actuating portion 46 which is pivotally moved toward a fitting opening 18 of the housing 12 to bring the contact portions 32 of the contacts 14 into contact with the connecting object.
