The gas-blasted circuit-breaker includes a movable arc contact, a fixed arc contact opposing the movable arc contact, an insulating nozzle, a puffer cylinder, a hollow conductor, an insulating rod connected to the puffer cylinder, and a fixed piston fitted inside the puffer cylinder. An insulating gas is ejected to a space between the puffer cylinder and the fixed piston by driving the insulating rod and is sprayed to an arc generated upon interruption of a current. The hollow conductor is in a cylindrical shape having a cross section parallel to the axis thereof. The cross section is smaller in diameter on the downstream side of a flow of insulating gas. The hollow conductor has a closed end on the downstream side of the flow of insulating gas and has a cylindrical barrel portion provided with a plurality of opening. With this configuration, this circuit-breaker ensures an operation of adjusting the flow of a heat gas, cooling of the heat gas and insulating performance for the fixed conductor to which the heat gas is sprayed.

A method of the present invention for producing a polarizing plate including a polarizer and a transparent protective film provided on one side of the polarizer with an adhesive layer interposed therebetween, include the steps of: (A) irradiating at least one side of a polarizer with vacuum ultraviolet rays to treat a surface of the polarizer; (B) bonding a first transparent protective film to the side of the polarizer, which has been subjected to the surface treatment step (A), with a first adhesive layer interposed therebetween to produce a temporary polarizing plate; and (C) peeling off the first transparent protective film and a surface layer of the polarizer, which has been subjected to the surface treatment, from the temporary polarizing plate. A thin polarizing plate in which shrinkage-induced bending is reduced may be obtained by the method.
