Abstract: PURPOSE: To improve uniformity of beam spots on the whole surface of a screen, so as to obtain high resolution over the whole surface of the screen, by making a structure wherein the focal distance in the vertical direction is provided with the astigmatism longer than that in the horizontal direction in the whole electron gun. CONSTITUTION: In a sub lens SL, electron beam passing holes of a third grid G3 on a fourth grid G4 side and electron beam passing holes of the grid G4 and a fifth grid G5 on the grid G4 side are respectively formed into a lateral hole extending in the horizontal direction. Accordingly, the convergence action in the vertical direction is provided with the astigmatism stronger than that in the horizontal direction. In a main lens ML, an electron beam passing holes of the grid G5 on a sixth grid G6 side and electric beam passing holes of the grid G6 on the grid G5 side are respectively formed into the longitudinal hole.  Since the convergence action in the horizontal direction is provided with the astigmatism stronger than that in the vertical direction in the whole electron gun, the remarkable deterioration of the resolution on the periphery of a screen is decreased, and uniformity of the beam spots on the whole screen can be improved.

Filed: 1989-11-15
Abstract: PURPOSE:To achieve click feeling excellent in operational sensitivity by pressing a curved portion in such a direction as to be curved when the stationally spring supporter of the curved portion and a rotational supporter are aligned in a straight line. CONSTITUTION:Since a stationary end 124 of a curved portion 121a of a plate spring 12, a spring supporter 111a and a rotational supporter 113 are aligned in a straight line, when a switch knob 11 is located in such a position (as the broken line 11a) that the rotation thereof is restricted by the tip end of a slant portion 134 at the end of the opening 137 of a case 13, a force is applied to the spring supporter 111a by return of the curved portion 121a. The direction of the force is oriented from the supporter 111a toward the supporter 113 (an arrow E), that is, no force exerts in the direction of rotation of the switch knob 11. A rotational force applied to the knob 11 is only a force (an arrow D) to rotate the knob 11 toward the case 13 by a restoring force (an arrow A) of the stationary end 124 of the curved portion 121. The rotation of the knob 11 up to the rotational limit against the restoring force of the plate spring 12 enables the contact of a switch 14 to be switched.
