Abstract
A method of for developing a panel in manufacture of a cathode ray tube which prevents possible dispersion of developing liquid to achieve a good developing operation free from irregular development. The method comprises fixing a panel, jetting developing liquid by way of a nozzle toward an inner face of the panel while moving the nozzle in a direction along stripes of a fluorescent face to be formed on the inner face of the panel to perform development of the panel.
Claims8
A method of cleaning a panel in the manufacture of a cathode ray tube, a cathode ray tube of the type having a plurality of parallel color stripes of a fluorescent face formed on the inner face of the panel, comprising the steps of fixing a panel at a position, and jetting developing liquid by way of a nozzle toward an inner face of the panel while moving said nozzle in a direction corresponding to elongate strip regions allocated on the inner face for stripes of a fluorescent face to be formed on the inner face of the panel, to perform development of the panel.
A method of cleaning an inner face of a cathode ray tube panel in the manufacture of a cathode ray tube, the cathode ray tube of the type having a plurality of parallel color stripes of a fluorescent face formed on the inner face of the panel, comprising the steps of:
- holding the panel in a frame;
- providing a supply of water and a plurality of nozzles flow connected to the supply of water;
- arranging the nozzles in a spaced environment corresponding to elongate strip regions allocated for parallel, spaced apart color stripes to be developed on the inner front face of the panel;
- jetting water from said nozzles against the inner face of the panel;
- and
- translating nozzles with respect to the panel along the longitudinal direction of said strip regions.
