わかる。As shown in FIG. 9, the CRT funnel 2, particularly near the neck tube, has a cone shape (conical shape) in consideration of productivity. This is because each cradle in each process in CRT manufacturing requires the same shape. As described above, the cross-sectional view near the neck tube is circular, and the center of the circle of each cross section corresponds to the tube axis of the CRT. The funnel 2 is placed on the cone gauge of the CRT mount (round opening) 5 shown by the alternate long and short dash line in FIG. 9 and centered, and the panel abutment 6 and the funnel abutment 7 shown in FIG. To be struck. The panel abutment 6 and the funnel abutment 7 form a part of the CRT mount 5, and CR
It is connected to the T frame (gauge) 5 via a support piece 8. Note that FIG. 11 is a contour diagram showing the outer shape of the neck tube and the funnel portion in the vicinity thereof. As shown in FIG. 11, the funnel near the neck tube has a neck tube outer diameter 3a.
It can be seen from the figure that it is a concentric cone with the diameter gradually increasing.

= K · D 2 / L · Sin 2 θ · HV. In this equation, K is a constant, D is the average diameter of the deflection yoke core and coil, L is the average length of the deflection yoke core and coil, and HV is the anode voltage.

きず、大幅な設備投資が必要である。However, it is difficult to handle the elliptical funnel. That is,
As shown in FIG. 14, the elliptical funnel 12 has a round C shape.
When it is placed on the RT pedestal 5, the place having the largest diameter (contact portion) becomes a point and becomes unstable. Therefore, the elliptical funnel C
In RT manufacturing, the conventional CRT frame (round inner diameter) cannot be used, and a large capital investment is required.
