2. Description of the Related Art Conventionally, cathode ray tubes have been used for cathode ray tubes for televisions and CRTs for monitor devices for personal computer equipment. In the case of a color cathode ray tube, the manufacturing method is to form RGB of the three primary colors and a matrix layer on the back surface side of the panel, and join the funnel having the frit portion corresponding to the frit portion of the panel to the panel via the frit seal material. After setting it on the transfer jig, place it on the net conveyor and blow the heated air from the bottom to the top while moving in the frit seal furnace to heat the panel part and the funnel part. A cathode ray tube is obtained by fusing a sealing material.

A conventional frit seal furnace will be briefly described with reference to the accompanying drawings. FIG. 10 is a plan view (a) and a front view (b) showing an inlet portion of the conventional frit seal furnace.
