Abstract

PURPOSE: Out of the plural number of damper line to be installed stretching on the aperture grill for the negative line tube of trinitrone method, after at least a piece of damper line is installed with stretch, the panel surface of the negative pole line tube is exposed. After that, arrangement is made so that the remaining damper lines may be installed with stretch to prevent the vibrating energy of the fine stripe portion and stripes of the grill from being put out of order.
