KR980005236A - Film for manufacturing deflection member of cathode ray tube and deflection member laminated and molded - Google Patents

Abstract

The present invention provides a cathode ray which can produce a deflection member by laminating a plurality of planarized films without forming or damaging films or wires and without forming defects such as wrinkles and forming them in a predetermined shape at the deflection portions. Provided are a film for producing a deflection member of a pipe, and a deflection member obtained by laminating and molding them. The film is dispersed and included in at least one of the base layer, the insulating adhesive, and the upper protective layer constituting the film so that the granular to powdery thermosetting resin is cured at high temperature forming to maintain a predetermined shape. . Accordingly, by molding each film or the reinforcing member in a predetermined shape, it is possible to stably solidify it into a predetermined shape, and furthermore, the deformation due to the temperature rise does not occur even during operation of the cathode ray tube. There is an effect that the deflection magnetic field pattern becomes constant without change over time.
