Abstract: PURPOSE: An electron gun for a CRT(Cathode Ray Tube) with electrodes is provided to reduce aberration of electron beams caused by large-diameter holes, to change the sectional area of electron beams to a desired shape and to improve focusing of electron beams by reducing focus voltage difference between electron beams passing the holes. CONSTITUTION: A prefocus lens is formed between a control electrode and screen electrode(53) while a main lens is between the first and second condensing electrodes(60,70). The main lens forms an electron lens and the electron beams pass through the electron lens as an equipotential surface is formed in a normal direction of an electric force. The electron beams are influenced by different condensing elements through central and both small-diameter holes(63G,73G,63R,63B,73R,73B) because of asymmetric large-diameter holes(61,71). The focusing of electron beams is reduced by induction of focus voltage difference. The electron gun obtains distortion and extension of the pass holes by difference between horizontal and vertical diffusion force through a horizontal portion around the small-diameter holes and a curve portion at both sides. Lips(65,75) are formed on the small-diameter holes toward the electron beams to reduce influence by distortion of diffusion force of the large-diameter holes.

An ATC(Analog Trunk Circuit) in the ARS, detecting the ring transmitted through the PBX(S5), hooks off according to the control of an MPU(S6) and sends a primary advertising message stored in a DKU through a VPC(S7). The ARS searches the caller phone number in a subscriber database(S8). If the caller phone number is not the phone number of a subscriber registered in the subscriber database, the ARS reads a negative information message from the DKU, sends it to the caller through the PBX(S9) and cuts off the call path(S10). In case that the caller phone number is the phone number of a subscriber registered in the subscriber database, the ARS reads a positive information message from the DKU and sends it to the caller through the PBX(S11).
