본 발명은 벌브에 전자총을 비밀봉 접속시켜 디스플레이 하는 방법과 그 장치에 관한 것이다.The present invention relates to a method and an apparatus for displaying a non-sealed electron gun connected to a bulb.

컬러수상관은 형광면과 샤도우마스크를 보유하는 벌브에 전자총을 접속시켜 내부가 진공이 되도록 밀봉시켜 구성된다. 그러므로 컬러 수상관의 품질은 벌브의 형광면과 샤도우마스크 그리고 전자총의 특성에 따라 좌우되기 때문에, 예로부터 이들 주요부품의 성능향상을 도모하여 컬러 수상관의 품질을 향상시키려는 실험이 무수히 행해지고 있다.The color water pipe is constructed by connecting an electron gun to a bulb having a fluorescent surface and a shadow mask to seal the inside to be vacuum. Therefore, since the quality of the color receiving tube depends on the characteristics of the fluorescent surface of the bulb, the shadow mask, and the electron gun, numerous experiments have been conducted to improve the quality of the color receiving tube by improving the performance of these main components.

통상적으로 컬러 수상관의 품질측정 방법은 예정된 사양에 따라 실험용 수상관을 특별히 제작하고, 이를 실제사용 조건하에서 디스플레이 하는 방법에 의존하고 있다. 이 방법은 일단 제조된 실험용 수상관의 해체가 사실상 곤란하기 때문에 매 실험시마다 전용의 수상관을 개별 제조해야 하므로 실험측정에 소요되는 노력과 시간이 많이 허비되고, 실험결과가 좋지 않으면 폐기 처분되어지는 비경제적인 결점이 있다.In general, the quality measurement method of a color water tube depends on a method of specially manufacturing an experimental water tube according to a predetermined specification and displaying it under actual use conditions. Since this method is difficult to dismantle the experimental tube once manufactured, it is necessary to manufacture a dedicated tube separately for each experiment. Therefore, it takes a lot of effort and time for experimental measurement. There is an uneconomical flaw.

본 발명의 목적은 상기한 결점을 해결하기 위하여 컬러 수상관을 구성하는 벌브와 전자총이 비밀봉 상태로 접속되어 디스플레이 될 수 있는 방법을 제공하여 실험측정 완료후에 이를 해체해서 다른실험에 재차 공여 될 수 있도록 함에 있다.The object of the present invention is to provide a method that can be displayed by connecting the bulb and the electron gun in a sealed state to solve the above-mentioned defects can be dismantled after the completion of the experimental measurement can be re- donated to another experiment. It is in such a way.

본 발명의 다른 목적은 벌브와 전자총을 비밀봉 상태로 접속 시키고 이들을 디스플레이 하기에 접합한 장치를 제공함에 있다.It is another object of the present invention to provide a device in which the bulb and the electron gun are connected in a hermetically sealed state and bonded to display them.

본 발명에 의한 디스플레이 방법은 벌브와 전자총의 접속부를 적당한 용기내로 삽입시켜 비밀봉 접속한 다음, 용기내부의 공기를 흡출 배기시켜서 고진공 상태가 되도록 한 후 전자총을 동작시켜 디스플레이 함을 특징으로 하는 것이며 이를 첨부도면에 따라 상세히 설명하면 다음과 같다.The display method according to the present invention is characterized in that the connection between the bulb and the electron gun is inserted into a suitable container, and the non-sealed connection is made. When described in detail according to the accompanying drawings as follows.

용기체(1)은 일측에 벌브소(3)이 고정 설치된다.The container body 1 is fixed to the bulb saw 3 on one side.

본 실시예에서 벌브소(3)은 용기체(1)에 대해 시일부재S를 개재하며 나사 체결됨으로써 기밀성을 보전토록 하고 있으나 벌브소(3)은 용기체(1)로부터 일체로 형성되어도 좋다.In the present embodiment, the bulb saw 3 is screwed to the container body 1 via the sealing member S to preserve the airtightness, but the bulb saw 3 may be integrally formed from the container body 1.

벌브소(3)은 중앙에 소공(4)를 보유하며, 이 소공(4)의 종단측에는 유니온 컬러(5)가 형성된다.The bulb saw 3 has a small hole 4 in the center, and a union collar 5 is formed on the end side of the small hole 4.

유니온 컬러(5)에는 유니온 캡(6)이 시일부재S를 개재하여 나사체결된다.The union cap 6 is screwed into the union collar 5 via the sealing member S. FIG.

벌브소(3)이 설치되는 부위와 대향하는 위치에는 나삽공(7)이 뚫려지고, 이 나삽공(7)을 통하여 전자총소(8)이 나사체결된다.A screw insertion hole 7 is drilled at a position facing the site where the bulb saw 3 is installed, and the electron gun 8 is screwed through the screw insertion hole 7.

전자총소(8)도 용기체(1)에 대해 시일부재S를 개재하여 체결됨으로써 기밀성을 보전하도록 부착된다.The electron gun 8 is also attached to the container body 1 via the sealing member S so as to preserve the airtightness.

전자총소켄(8)은 중앙에 소경오목부(9)의 중심에 삽입공(11)이 뚫려지고 패킹링(12)가 끼워져서 안치 보존된다.Electron gun soken 8 is inserted into the hole 11 in the center of the small diameter concave portion 9 in the center and the packing ring 12 is fitted into the preservation.

삽입공(11)이 뚫려지는 위치는 전술한 벌브소(3)의 소공(4)와 동일축선상에 놓여지는 지점으로 된다.The position at which the insertion hole 11 is drilled becomes a point which lies on the same axis as the small hole 4 of the bulb saw 3 mentioned above.

용기체(1)에는 이와 같이 벌브소(3)과 전자총소(8)에 설치되는 외에도 다른 적당한 부위에 니플(13)이 돌출 형성되고, 밸브가 달린 질소 주입관(15) 및 접속관(16)이 설치된다.In the container body 1, the nipple 13 is protruded and formed at the other suitable site in addition to the bulb element 3 and the electron gun 8, and the nitrogen injection tube 15 and the connection tube 16 with valves are formed. ) Is installed.

니플(13)에는 진공측정 유니트(14)가 접속되어 통공(15)를 통해 공간(2)의 진공도를 측정할 수 있게 된다.The nipple 13 is connected to a vacuum measuring unit 14 so that the vacuum degree of the space 2 can be measured through the through hole 15.

진공측정 유니트(14)는 니플(13)에 나사 첵ㄹ되는 척(14)를 보유하며, 체결시에 기밀성이 유지되도록 시일부재S와 부싱 b 및 베어링 B등의 부속물을 보유한다.The vacuum measuring unit 14 holds the chuck 14 which is screwed into the nipple 13 and has the accessories such as the seal member S, the bushing b and the bearing B so that the airtightness is maintained at the time of tightening.

전기한 접속관(16)은 진공펌프 P에 접속된다.The connection tube 16 mentioned above is connected to the vacuum pump P. FIG.

상술한 본 발명의 디스플레이 장치에는 벌브소(3)을 통하여 실험용 밸브A가 삽입되고 전자총소(8)에 전자총G가 삽입되어 디스플레이를 행하게 된다.In the above-described display device of the present invention, the experimental valve A is inserted through the bulb saw 3 and the electron gun G is inserted into the electron gun 8 to perform the display.

즉, 벌브소(3)의 소공(4)에 밸브 A를 끼우고 용기체(1)의 나삽공(7)을 통하여 유니온캡(6)을 유니온 컬러(5)에 나사체결 시키면 벌브A의 접속부A'는 제2도의 도시와 같이 공간(2)로 노출된 상태에서 시일부재S에 압지 보전된다. 다음에 전자총소(8)을 나삽공(7)에 체결부착하고, 니플(13)에는 진공측정 유니트(14)를 연결 접속시킨다.That is, when the valve A is inserted into the small hole 4 of the bulb saw 3 and the union cap 6 is screwed into the union collar 5 through the threading hole 7 of the container body 1, the connection portion of the bulb A is A 'is squeezed and retained in the sealing member S in the state exposed to the space 2 as shown in FIG. Next, the electron gun 8 is fastened and attached to the screw insertion hole 7, and the nipple 13 is connected and connected with the vacuum measuring unit 14.

그리고 전자총소(8)의 삽입공(11)에 전자총G를 삽입시킨다.Then, the electron gun G is inserted into the insertion hole 11 of the electron gun 8.

전자총G는 그 선단의 접속부G'가 공간(2)로 노출되도록 삽입되어 벌브소(3)에 삽입 지지된 벌브A의 접속관 A'와 비밀봉 상태로 접속된다.The electron gun G is inserted in such a way that the connecting portion G 'of the tip thereof is exposed to the space 2 and is connected to the connecting tube A' of the bulb A inserted and supported by the bulb saw 3 in an unsealed state.

또한 전자총G가 삽입공(11)에 삽입되면 패킹링(12)는 기밀성을 보전해 주게 되고, 전자총소(8)의 중앙에 형성된 대경오목부(10)은 전자총G의 삽탈조작이 수월하도록 활동공간을 제공하게 된다.In addition, when the electron gun G is inserted into the insertion hole 11, the packing ring 12 preserves the airtightness, and the large diameter recessed portion 10 formed at the center of the electron gun 8 facilitates the insertion and removal operation of the electron gun G. To provide space.

상기한 바와 같이 용기체(1)에 벌브A와 전자총G가 삽입되면 용기체(1)은 외부와 차단된 밀폐상태로 놓여진다. 이 상태에서 접속관(16)에 연관된 진공펌프P를 구동시켜 용기체(1)의 공간(2)를 진공으로 만든다. 용기체(1)의 공간(2)가 진공화 하게 되면 그 진공도는 진공측정 유니트(14)를 통하여 읽을 수 있다.As described above, when the bulb A and the electron gun G are inserted into the container body 1, the container body 1 is placed in a hermetically sealed state. In this state, the vacuum pump P associated with the connecting pipe 16 is driven to vacuum the space 2 of the container body 1. When the space 2 of the container body 1 is evacuated, the degree of vacuum can be read through the vacuum measuring unit 14.

공간(2)의 진공도가 10-5Torr정도로 되어지면 전자총G에 정격전압을 인가하여 디스플레이를 행하여 실험측정을 한다.When the vacuum degree of the space (2) is about 10 -5 Torr, the test is performed by applying the rated voltage to the electron gun G and performing the display.

이때, 필요하다면 측정 중에도 진공펌프P를 계속 구동시켜 적정한 진공도를 유지시킬 수 있다. 측정이 끝나면 진공펌프P를 끄고, 질소 주입관(15)의 밸브를 열어 용기체(1)의 공간(2)에 질소개스를 충전한다.At this time, if necessary, it is possible to maintain the proper vacuum degree by continuously driving the vacuum pump P during the measurement. After the measurement, the vacuum pump P is turned off, and the valve of the nitrogen injection pipe 15 is opened to fill the space 2 of the container body 1 with nitrogen gas.

공간(2)에 충전되는 질소개스는 불활성개스이므로 전자총G의 캐소드를 둘러 쌓아 줌으로서 진공해제시 외기중의 산소와 접촉되지 않도록 하여 캐소오드의 산화를 방지해 준다.Since nitrogen gas filled in the space 2 is an inert gas, it surrounds the cathode of the electron gun G so that it does not come into contact with oxygen in the outside air during vacuum release, thereby preventing the oxidation of the cathode.

질소개스를 충전한 후에 전자총G가 냉각될때 까지 대기한 다음, 상온으로 냉각되면 순서대로 분해를 행하여 벌브A를 빼냄으로서 실험에 제공된 벌브A와 전자총G를 회수하여 다른 실험에 재사용 한다.After charging the nitrogen gas, wait until the electron gun G is cooled, and when cooled to room temperature, the decomposition is performed in order to remove the bulb A, and the bulb A and the electron gun G provided in the experiment are recovered and reused in another experiment.

주지된 바와 같이 상온에서는 캐소오드와 산화가 진행되지 않으므로 상온으로 냉각시킨 후에 해체하면 캐소오드의 산화는 발생하지 않는다.As is well known, since the oxidation with the cathode does not proceed at room temperature, the oxidation of the cathode does not occur when disassembled after cooling to room temperature.

상술한 바와 같이 본 발명에 의하면 벌브와 전자총을 비밀봉 접속시켜 디스플레이를 행할 수 있으므로 컬러 수상관의 연구 개발에 있어서 노력과 시간을 절약할 수 있고 재사용에 의한 경제적인 이익을 도모할 수 있는등의 장점을 얻을 수 있음은 물론이려니와, 컬러 수상관의 생산에 있어서 라인을 통하여 공급되는 각개부품의 유무를 무작위로 선정하여 검사하는 데에도 유용하기 때문에 컬러 수상관의 품질 향상에도 기여하는 바가 크다.As described above, according to the present invention, since the bulb and the electron gun can be connected to the non-sealed display, it is possible to save effort and time in the research and development of the color award tube, and to achieve economic benefits by reuse. Not only can the advantages be obtained, but it is also useful for randomly selecting and inspecting each component supplied through the line in the production of color water pipes, thus contributing to the improvement of the quality of the color water pipes.
