摘要： PROBLEM TO BE SOLVED: To provide a deflection yoke which radiates a quantity of heat generated in it in air with high efficiency, through low in cost, and which can reduce in temp. rise of the yoke to a great extent and to provide a cathode-ray tube display device using it. SOLUTION: A heat radiation fin 60 of a radiating mechanism 6 has a plurality of plate members, arranged parallel with one another and also parallel with the horizontal direction of a magnetic core. A holder part 61 has a mounting part 63 to the magnetic core, and the part 63 is shaped semispherically so as to creep on the outer wall surface of the magnetic core. The heat-radiating mechanism 6 consists of a consolidated construction of a plurality of such radiation fins 60 and holder parts 61 and is yielded from a high thermal conductivity material through an extrusion process in the direction, perpendicular to this sheet of description, which can be accomplished by a single run of extrusion. Therefore, its fabricating costs remain low.

摘要： PROBLEM TO BE SOLVED: To remarkably reduce temperature rise of a deflection yoke by efficiently radiating heat generated in a horizontal deflection coil whose temperature rise is the largest in the deflection yokes. SOLUTION: High heat conductivity members 13a-13c are placed between members in a heat transmitting path from a horizontal deflection coil 2 to a magnetic core 5, and a heat radiating fin 6 for increasing the contact area with air is arranged on the outer wall surface of the magnetic core 5. 20% or more of the whole gather area of the heat radiating fin 6 are laterally extruded from the outer wall surface of the magnetic core 5 in order to increase the contact surface with air, and air is made to easily flow from the lower part to the upper part through between gathers 60 of the heat radiating fin 5 to enhance heat radiation effect.

摘要： PURPOSE:To obtain a shielding effect without using a shielding plate, excellent assembly workability, and cost reduction by setting a side wall higher so as to protrude from the sealing surface of a panel to the neck side and widely forming the bottom so that an electron beam cannot collide against the said side wall. CONSTITUTION:The side wall 10a of a support frame 10 is formed higher so as to protrude from the sealing surface 16 of a panel 13 and a funnel 15 to the neck side. In addition, the bottom 10b of a support frame 10 is formed widely so that an electron beam can be prevented from colliding against the said side wall 10a. As a result, since side wall 10a is formed higher, it cuts off the electron beam that arrives at a phosphor screen 13a passing through the support frame 10 and bulbs 13 and 15 and is also provided with an effect that screens the effect of an external magnetic field. In other words, the side wall 10a has the outside electron shield and inner shield characteristics. In addition, since the bottom 10b is widely formed, the same effect as the inside electron shield can be obtained.

摘要： PURPOSE:To fix a contact spring in a cathode-ray tube only by means of the spring force instead of welding process by making the cathode-ray tube consist of a press contact section that is connected to an engagement section and makes press-contact with a frame side wall and a connection section that connects this press contact section to a shaping section. CONSTITUTION:Figure (a) shows the status where a spring is mounted before a funnel 2 is fit. A contact spring 1 is mounted on a frame 3 by engaging the engagement section 1b of the contact spring 1 with the intra-flange end of the frame 3 and pressing the spring 1 in the direction of an arrow (A). Besides, when a force is applied from the direction of an arrow (B) in this state, the contact spring 1 can easily be removed from the frame 3. Figure (b) shows the status where the funnel 2 is fit. The press contact section 1C of the contact spring 1 is pressed on the side of the frame 3 by the force shown by the direction of an arrow (C) from the funnel 2 and the contact spring 1 will not be slipped off from the frame 3.

摘要： PURPOSE:To provide a deflection yoke with which desired degree of comatic aberration and trilemma can be corrected and which has excellent vertical deflection sensitivity. CONSTITUTION:Almost E-shaped magnetic bodies 10A, 10B, a core on which a vertically deflecting coil 4 is coiled, and magnetic bodies 6A, 6B for magnetic field leakage are installed in an electron gun side of a deflection yoke 2 wherein the magnetic bodies 6A, 6B are set between the E-shaped magnetic bodies 10A, 10B and are longer in tube axial direction than in the horizontal axial direction. At the same time, the almost E-shape magnetic bodies 10A, 10B are provided with at least a pair of auxiliary coils 13 which are connected with the vertically deflecting coil 4 in series. Consequently, the comatic aberration and trilemma in the upward and downward directions of a screen can be corrected as desired without mutual interference solely by the deflection yoke. Also the coiling times and the resistance of the auxiliary coil are lessened and the vertical defection sensitivity is improved.

摘要： PURPOSE:To enable a lead protector for a cathode-ray tube to be easily and reliably attached to the lead section by allowing a gap between the convex section and the end of the focus outer pin when the convex section is inserted into the base barrier and forming a concave area in the center of the convex section. CONSTITUTION:A lead protector 20 has a fan-shaped convex section 21 which can be inserted into a barrier 7. When the convex section 21 is inserted into the barrier 7, a gap of several milimeters is formed between the end of a focus outer pin 6 and the top surface of the convex section 21. And, the connection area between the convex section 21 and the barrier 7 has a length of 3-5mm.. Besides, a concave area 22 is formed in the center of the convex section 21. Because of the above structure, the lead protector 20 can be very easily attached to a cathode-ray tube 2. Furthermore, since the convex section 21 is inserted into the fan-shaped barrier 7 by 3-5mm., the lead protector 20 is reliably attached to the base 1 and any mis-insertion of the convex section 21 is prevented.
