A functional film sticking apparatus includes: a separator peeling unit for peeling a separator from a functional film having the separator stuck on the functional film via an adhesive; a functional film sticking unit for sticking the functional film, from which the separator has been peeled by the separator peeling unit, on a panel surface; and a film fixing portion for carrying the functional film at least from the separator peeling unit to the functional film sticking unit while holding the functional film by suction, the film fixing portion being provided with a roller for sticking the functional film. The separator peeling unit is provided with a suction device for sucking, upon peeling the separator from the functional film, the atmosphere at the portion to be peeled and its neighborhood, or is provided with an electrostatic eraser for removing, upon peeling the separator from the functional film, electrostatic charges at the portion to be peeled and its neighborhood. With this apparatus, it is possible to reduce the entrapment of air and foreign matters upon sticking a functional film on a product and hence to improve the quality of the product on which the function film has been stuck.

Functional film sticking apparatus and functional film sticking method

A cathode ray tube which comprises a front panel coated with a nonglare film having a multi-layered structure. The multi-layered structure comprises at least a visible light absorbing layer containing a black dye, and an antistatic layer containing an inorganic metal compound as a conductive agent.

Cathode ray tube with a nonglare multi-layered film

An electrical insulator, provided between a stem of a cathode-ray tube and a stem base mounted to the stem is arranged, for insulating stem pins erected on the stem from each other, thereby improving the dielectric strength between the stem pins and a cathode-ray tube on which the electric insulator is mounted. The electrical insulator includes a fixed portion held between the stem and the stem base, and a projecting portion to be caught in a tip-containing portion of the stem base, the projecting portion being formed integrally with the fixed portion, wherein the fixed portion is provided with pin containing portions for containing the stem pins to be insulated by forming notches in the fixed portion on the outer edge side.

This invention secures the breakdown voltage between stem pins or the like for high voltage service in a cathode ray tube. This insulator formed is of a clay-like silicone compound having a tip-throughhole and pin-throughholes or a stem base with the electric insulator mounted to the stem base: A inter-stem electric insulation device is structured by mounting either one of the electric insulator or the stem base with the electric insulator to the stem of a cathode ray tube and by pressing to fix together. This structure does not occur bubble generation caused by the electric insulator, and makes the handling easy, and furthermore, accomplish an automatic mounting of the electric insulator to a stem.
