Title: Electron gun for color cathode-ray tube
Inventor: IN NOUYOU
IPC: H01J29/50
Filed: 1994-05-10
Abstract: PURPOSE: To improve focus characteristic at the center of a screen by forming an electron beam-passing hole for a control electrode, forming a three pole part of an electron gun in long sideways type and forming a long sideways type slot at incident face side of a screen electrode opposite to the control electrode. CONSTITUTION: Three long sideways type electron beam, passing holes 32H are formed in inline shape in a control electrode 32 and long sideways type slots 33S surrounding the electron beam passing holes 33H, are formed at incident face side of a screen electrode 33 opposite to the electrode 32. Since the passing holes 32H are formed in long sideways shape by this constitution, loading area of a vertical direction area in which the electron beam passes is reduced. Thereby, vertical object point diameter of the electron beam discharged from a cathode 31 is formed relatively small. While, incident angle of a cross over point of the electron beam is relatively reduced by the slots 33S of the electrode 33 and focusing characteristic of high current area is improved.

Title: Search system for preset channel
Inventor: OTANI HIDEHIRO
IPC: H03J7/18
Filed: 1990-04-13
Abstract: PURPOSE:To select an objective channel in a short time without taking time to search for a duplicated station by skipping the preset channel of the same station at the time of preset searching. CONSTITUTION:When a preset scan switch 4 is inputted, a microcomputer 2 searches successively for preset stations stored in its inside. At the time of the search for the preset station, the microcomputer 2 decides whether the same station as the station at present was searched for before or not, and if the same station was not searched for before, it keeps that section in a receiving state for a fixed time. On the contrary, if the same station was searched for before, it skips that station, and searches for the next station. Thus, the same station is never searched for repeatedly, and the preset channel station can be searched for in a shortest time, and the channel selecting operation can be executed in a short time.
