The structure of an electron gun for a cathode ray tube of the invention is effective for enhancing the resolution of the screen without an application of a dynamic voltage.

Abstract: An electron gun for a color CRT includes a main focusing lens unit that focuses the electron beams generated by a triode unit. The main focusing lens unit includes a first and a second electrostatic screen grid having three electron beam through holes linearly-arranged for passing three electron beams, two of the holes being external and an oval shaped hole that passes all three electron beams. The oval shaped holes being spaced a distance, d1 and d2, respectively, from the through holes. Furthermore, the first grid external holes have an external distance HL1 and an internal distance HR1 and the second grid external holes have an external distance HL2 and an internal distance HR2; and wherein HL1 is greater than HR1, HL2 is greater than HR2, d1 is greater than d2, HL2 is greater than HL1, and HL2+HR2 is greater than HL1+HR1.

Abstract: A method for displaying an absence message in a private exchange system. More specifically, a method for displaying on a calling party's telephone, a message containing the reason for a called party's absence and the beginning and ending points of the absence in either a time or date format. The method is accomplished by a party registering an absence message on a keyphone, so that a reason for an absence and the period of absence will sent and displayed on variable visual display of the calling party's telephone when the party is called while absent.
