The present invention provides an improved feeling of flatness of a color cathode ray tube which facilitates the coating operation of a phosphor layer or enlarges an effective area of the phosphor layer. The valve includes a housing having an interior, at least one port to provide fluid communication between the housing interior and atmosphere and at least one flap including a first portion and a second portion. The control unit has a function of determining whether ID information of the storing member andor the discharge receiving member, which is a work target of the previously incorporate program, is identical to ID information of the storing member andor the discharge receiving member mounted on the table. The manufacturing method further includes applying a structural coating on at least a portion of the substrate and processing at least a portion of the surface of the structural coating so as to plastically deform the structural coating at least in the vicinity of the top of a respective groove, such that a gap across the top of the groove is reduced.
