A flat display device includes cathodes, a screen plate having a fluorescent screen, a plate-like electrode for controlling electron beams from the cathodes to the fluorescent screen, and a frame body for supporting the plate-like electrode. The frame body securely fixes both ends of the plate-like electrode at two opposite sides thereof, and has an elastic body for supporting the plate-like electrode in a stretched state by a spring force of the elastic body. The flat display device is made by the steps of pressing a pair of leaf springs provided respectively at two confronting sides of a frame body to thereby bend the frame body in such directions that the confronting sides become close to each other, securely fixing both ends of a plate-like electrode to the pair of bent leaf springs, and releasing the pressing of the leaf springs to thereby restore the leaf springs.

A method for fixing to a frame an electrode or a shadow mask for an image receiving tube. The method includes steps for stretching, in opposite directions, supporting ends of a rectangular mask plate having apertures formed between the supporting ends, in order to generate a tensile force having a uniform distribution over the entire surface of the plate. The method also includes pressing inwardly and bending a pair of elastic supporting elements, constituting two confronting sides of a frame, so that a distribution of the pressing force in a direction of each of the sides almost balances with a distribution of the tensile force. The supporting ends of the mask plate are then rigidly fixed to both of the bent supporting elements of the frame. The stretching and pressing forces applied to the mask plate and the frame are then released.

A color selecting electrode for a color-picture tube, includes a rectangular frame-shaped frame having a pair of mutually-opposite long sides and a pair of mutually-opposite short sides, and a mask plate which is stretchedly supported on top surfaces of the frame while receiving a resilient spring force exerted from the frame, the long sides having a greater section modulus and a greater rigidity than the short sides. A method of manufacturing the color selecting electrode includes the step of welding, to the frame pressed inward by an equally-distributed force applied to the pair of long sides and the pair of short sides, the mask plate of which four sides are stretched outward by a distributed force which approximately counterbalances the equally distributed force.

An apparatus for applying coating material in the form of stripes onto a film traveling in a predetermined direction is provided with a coating material nozzle which effuses coating material while supporting the film. The contact support surface of the nozzle in contact with the film is a flat surface, along which the film travels. The coating material nozzle has thereon applicator grooves for uniformly forming the cross-sectional shape of coating material applied in the form of stripes onto the film. Effusion ports or discharge ports for coating material are provided in the bottom surface of the applicator grooves. Coating material is fed to the coating material nozzle through a gear pump, which is adapted to control the coating material supply so that the coating material within the applicator grooves has a pressure lower than atmospheric pressure. In addition, there may be provided a plate member for blowing air uniformly and opposed to the contact support surface of the coating material nozzle contacted by the film. The air from this plate is blown against the traveling film on its rear side.
