Claims
- 1. A cathode ray tube comprising:an evacuated envelope including a panel section having a front face portion including a sloped sidewall, said sloped sidewall and an outer periphery portion being joined at mold match line, a neck containing therein an electron gun assembly, and a funnel section integrally coupling said panel section and said neck together; said sloped sidewall of said front faceplate having an angle which is in a range of 1.5 to 3 degrees to the tube axis; a thermal shrink fitted reinforcing band clamped around the outer periphery of said panel section; said reinforcing band being positioned around said panel section at a predefined position in which a circumferential bending line on said reinforcing band is offset from said mold match line of said cathode ray tube toward said neck.
- 2. The cathode ray tube according to claim 1, wherein said reinforcing band is provided with lugs.
- 3. The cathode ray tube according to claim 1, wherein said circumferential bending line of said reinforcing band is offset from said mold match line by 2 to 6 millimeters (mm).
- 4. The cathode ray tube according to claim 3, wherein said reinforcing band comprises a looped strip having one edge folded back over said strip so as to face in the direction of said neck to form a flap with its turned-back edge residing at a predetermined position which is offset from said mold match line toward said neck.
- 5. The cathode ray tube according to claim 3, wherein said reinforcing band comprises a looped strip having one edge folded back over said strip so as to face in the direction of said neck thereby defining a flap with its turned-back edge residing at a predetermined position which is offset from said bending line toward said face plate.
- 6. A cathode ray tube comprising:an evacuated envelope including a panel section having a front face portion including a sloped sidewall, said sloped sidewall and an outer periphery portion being joined at mold match line, a neck containing therein an electron gun assembly, and a funnel section integrally coupling said panel section and said neck together; said outer periphery portion having an angle which is in a range of 3 to 4.5 degrees to the tube axis; and a thermal shrink fitted reinforcing band clamped around the outer periphery of said panel section; said reinforcing band being positioned around said panel section at a predefined position in which a circumferential bending line on said reinforcing band is offset from said mold match line of said cathode ray tube toward said neck.
- 7. The cathode ray tube according to claim 6, wherein said reinforcing band is provided with at least one lug.
- 8. The cathode ray tube according to claim 6, wherein a sloped sidewall of said front faceplate has an angle which is in a range of 1.5 to 3 degrees to the tube axis.
- 9. The cathode ray tube according to claim 8, wherein said circumferential bending line is offset from the mold match line by 2 to 6 millimeters (mm).
- 10. The cathode ray tube according to claim 9, wherein said reinforcing band comprises a looped strip having one edge folded back over said strip so as to face in the direction of said neck to form a flap with its turned-back edge residing at a predetermined position which is offset from said mold match line toward said neck.
- 11. The cathode ray tube according to claim 9, wherein said reinforcing band comprises a looped strip having one edge folded back over said strip so as to face in the direction of said neck thereby defining a flap with its turned-back edge residing at a predetermined position which is offset from said bending line toward said face plate.
