본 고안은 칼라수상관의 화상보정용 자석에 관한 것으로, 더 상세히는 ITC(Integrated Tube Component)공정후 수상관의 펀넬상에 부착되는 화상보정용 자석에 관한 것이다.The present invention relates to an image correction magnet of a color water pipe, and more particularly, to an image correction magnet attached to a funnel of a water pipe after an integrated tube component (ITC) process.
종래 전자총에서 방사되는 전자빔의 궤도 위치와 방향보정 등을 위하여는 편향요크, 색순회자석.Deflection yoke, color circulating magnets for orbital position and direction correction of electron beams emitted from conventional electron guns.
콘버이젼스요크, 라테럴자석 등 여러가지 부품이 수상관의 구조나 종류에 따라 사용되어 왔다.Various parts, such as convergence yoke and lateral magnets, have been used depending on the structure and type of the receiving tube.
그러나 대형 수상관이나 공업용 수상관의 경우에는 이러한 부품만으로도 양호한 화면을 얻을 수 없는 경우가 있어, ITC공정 뒤 펀넬의 대각선 부위에 필요에 따라 화상보정용 자석을 붙여 최종적으로 화상을 보정하여 왔다.However, in the case of large water pipes and industrial water pipes, it is sometimes impossible to obtain a good screen with only such parts. After the ITC process, an image correction magnet is attached to the diagonal portion of the funnel as necessary to finally correct the image.
이를 위해 종래에는 단순히 원형의 Fe성분의 자석을 사용하여 왔다.For this purpose, conventionally, a circular magnet of Fe component has been used.
이러한 종래의 화상보정용 자석을 유리인 펀넬 상에 부착시킬 때 여러가지 문제점이 있었다.There have been various problems when attaching such a conventional image correction magnet onto a funnel made of glass.
펀넬의 곡률, 소위 수상관의 인치별 및 X, Y축별 곡률이 수상관마다 다르고, 그 재질이 유리인탓에 고정된 형태의 종래의 화상 보정용 자석은 부착시 안정성이 떨어지고, 또 자석 위에 보조지지용 테이프를 붙이더라도 접착력이 충분치 못하였다.Because the curvature of the funnel, the so-called curvature of each of the water pipes and the X- and Y-axis curvatures of the water pipes are different from each other, and the material is glass, the conventional image correction magnets, which are fixed in shape, are less stable when attached and are supported on the magnets. Even if the adhesive tape was applied, the adhesive strength was not sufficient.
따라서 본 고안은 자석의 구조 및 재질을 변경하여 펀넬상에 부착할 때 안정도를 높일 수 있는 화상보정용 자석을 제공하고자 하는 것이다.Therefore, the present invention is to provide a magnet for image correction that can increase the stability when attached to the funnel by changing the structure and material of the magnet.
이하 도면을 참조하여 본 고안을 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
제1도의 a, b, c는 각각 본 고안의 평면도, 정면도, 측면도이며, 제2도는 종래의 화상보정용 자석의 사시도, 제3도는 화상보정용 자석의 실시도 이다.A, b, and c of FIG. 1 are a plan view, a front view, and a side view of the present invention, respectively, and FIG. 2 is a perspective view of a conventional image correction magnet, and FIG. 3 is an embodiment of an image correction magnet.
본 고안의 화상보정용 자석(1)은 바닥 부위는 종래의 막대자석과 같은 형태이나 전체적으로 단순한 장방형의 막대 꼴이 아니라 제1도의 b,c에서처럼 윗쪽을 돔형으로 형성하였다.In the image correction magnet 1 of the present invention, the bottom portion is shaped like a conventional bar magnet, but is formed in a dome shape on the upper side as in b and c of FIG.
또한 재질은 소위 고무자석을 사용하였다.In addition, the so-called rubber magnet was used.
이러한 본 고안의 자석(1)은 필요에 따라 ITC공정후 제3도에서처럼 펀넬(F)상에 적당히 부착된다. 부착은 통상 공업용 본드를 사용하며, 안정도를 높이기 위해 부착후 접착 테이프(2)를 덧붙이기도 한다.The magnet 1 of the present invention is suitably attached to the funnel F as shown in FIG. 3 after the ITC process as necessary. In general, the industrial bond is used, and the adhesive tape 2 is added after the attachment to increase the stability.
이러한 본 고안의 자석은 그 형태가 장방형이므로 길이방향(도면의 화살표방향)을 전자빔의 방향과 일치시켜 종래의 원형자석에 비해 적은 착자량으로도 전자총으로부터 방사된 전자빔의 진로 보정이 가능하며, 고무성분인 탓에 수상관의 인치별이나 X, Y비별 곡률에 관계없이 판넬(F)면에 밀착될 수 있고, 또 돔형인 탓에 보조지지용 테이프(2)를 붙인 경우에도 보다 양호한 접착력을 가질 수 있다.Since the magnet of the present invention has a rectangular shape, the length direction (arrow direction in the drawing) coincides with the direction of the electron beam, and it is possible to correct the path of the electron beam emitted from the electron gun with less magnetization than the conventional circular magnet. Due to its component, it can be adhered to the panel (F) surface regardless of the curvature of the water pipe by the inch or X, Y ratio, and because of the dome shape, it has better adhesion even when the auxiliary supporting tape 2 is attached. Can be.
따라서 본 고안을 사용하면 수상관 판넬의 곡률에 관계없이 용이하게, 또 보다 견고하게 화상보정용 자석을 부착할 수 있다.Therefore, by using the present invention, it is possible to easily and more firmly attach the image correction magnet regardless of the curvature of the water pipe panel.
