Abstract
Abstract A method of adhering a film to a panel of a cathode-ray tube, comprised of adhering a light transmitting type functional film to the surface of a panel glass while interposing an ultraviolet ray-curable resin layer therebetween, then bringing the film into tight contact with the panel glass from the inside of one end portion toward that one end portion, then bringing the film into tight contact with the panel glass toward the other end. Further, when bringing the film into tight contact with the panel, by heating by irradiating the front surface of the panel by ultraviolet rays, the resin protruding from the periphery of the film is cured, the work process is shortened, and the handling is facilitated.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
94 words
A method of adhering a film to a substantially front facing surface of a cathode-ray tube comprising the steps of: adhering the film to the surface of said cathode-ray tube by using an adhesive; pressing said film to said light transmitting cathode ray tube starting from a position located at a distance inward from one lateral end of said surface, and pressing across said surface to said one end across said distance, and then reversing direction of said pressing and pressing from said one end to a respective opposite lateral end across said surface.
Claim 2
Independent Claim
94 words
A method of adhering a film to a substantially front facing surface of a cathode-ray tube comprising the steps of: adhering the film to the surface of said cathode-ray tube by using an adhesive; pressing said film to said light transmitting cathode ray tube starting from a position located at a distance inward from one lateral end of said surface, and pressing across said surface to said one end across said distance, and then reversing direction of said pressing and pressing from said one end to a respective opposite lateral end across said surface.
Claim 3
Dependent Claim
36 words
A method of adhering a film to a surface of a cathode-ray tube as set forth in claim 1, wherein said position is located laterally on an outside of an effective screen region of said surface.
Claim 4
Dependent Claim
27 words
A method of adhering a film to a surface of a cathode-ray tube as set forth in claim 1, wherein said adhesive includes an ultraviolet ray-curable resin.
Claim 5
Independent Claim
100 words
A method of adhering a film to a surface of a cathode-ray tube which bonds a light transmitting functional film to a surface of a panel glass, including the steps of: forming a layer of an ultraviolet ray-curable resin on said surface of said panel glass; adhering a light transmitting functional film to the ultraviolet ray-curable resin; providing that said ultraviolet ray-curable resin is arranged to protrude from the periphery of said functional film; and heating said ultraviolet ray-curable resin protruding from the periphery of said functional film while irradiating ultraviolet rays from a front surface of said functional film.
Claim 6
Independent Claim
100 words
A method of adhering a film to a surface of a cathode-ray tube which bonds a light transmitting functional film to a surface of a panel glass, including the steps of: forming a layer of an ultraviolet ray-curable resin on said surface of said panel glass; adhering a light transmitting functional film to the ultraviolet ray-curable resin; providing that said ultraviolet ray-curable resin is arranged to protrude from the periphery of said functional film; and heating said ultraviolet ray-curable resin protruding from the periphery of said functional film while irradiating ultraviolet rays from a front surface of said functional film.

Claim 8
Dependent Claim
37 words
A method of adhering a film to a surface of a cathode-ray tube as set forth in claim 4, wherein said protruding ultraviolet ray-curable resin is heated by blowing hot air to said protruding ultraviolet ray-curable resin.
Claim 9
Dependent Claim
38 words
A method of adhering a film to a surface of a cathode-ray tube as set forth in claim 6, wherein a time of blowing said hot air is within a range of from 2 seconds to 15 seconds.
Claim 10
Independent Claim
143 words
A method of adhering a film to a surface of a cathode-ray tube which bonds a light transmitting transparent functional film to the surface of a panel glass, including the steps of: forming a layer of an ultraviolet ray-curable resin on said surface of said panel glass; pressing said film to said surface starting from a position located at a distance inwardly from one lateral end of said surface, and pressing across said surface to said one end, and then reversing direction of said pressing and pressing from said one end to a respective opposite lateral end across said surface; providing that said ultraviolet ray-curable resin is arranged to protrude from the periphery of said functional film and heating said ultraviolet ray-curable resin protruding from the periphery of said functional film while irradiating ultraviolet rays from said front surface of said functional film.
Claim 11
Independent Claim
143 words
A method of adhering a film to a surface of a cathode-ray tube which bonds a light transmitting transparent functional film to the surface of a panel glass, including the steps of: forming a layer of an ultraviolet ray-curable resin on said surface of said panel glass; pressing said film to said surface starting from a position located at a distance inwardly from one lateral end of said surface, and pressing across said surface to said one end, and then reversing direction of said pressing and pressing from said one end to a respective opposite lateral end across said surface; providing that said ultraviolet ray-curable resin is arranged to protrude from the periphery of said functional film and heating said ultraviolet ray-curable resin protruding from the periphery of said functional film while irradiating ultraviolet rays from said front surface of said functional film.
