Abstract

A method for manufacturing a quick starting sleeve comprises blackening the surface of the sleeve by a wet hydrogen process (heat treatment in H2 atmosphere containing O2), controlling the generation of the blackened film by coating a thin hollow nickel plate on the outer surface of the sleeve, welding the sleeve and the nickel plate, and welding, after blackening only the inner surface of the sleeve, a cap on the sleeve by resistance welding.

본 발명은 속동형 슬리이브와 그 제조방법에 관한 것이다. 컬러텔리비젼에 있어서, 스위치를 켜면 화면이 즉시 현출되게 한 속동형이 예전부터 실용화되고 있다.The present invention relates to a fast-acting sleeve and a method of manufacturing the same. In color television, the fast-acting type which makes a screen appear immediately when a switch is turned on has been practically used.

속동형 컬러텔리비젼은 히이터 필라멘트에 열전자 방사물질을 직접 부착한 직열형이 주류를 이루었으나, 전자총의 수명이 짧은 관계로, 보다 수명이 긴 방열형 전자총에서 속동효과를 얻으려는 시도가 행해지고 있다.In the fast-moving color television, a direct heat type that directly attaches a hot electron radiating material to a heater filament is mainly used. However, due to the short life of the electron gun, an attempt is made to obtain a fast-moving effect in a longer heat dissipation electron gun.

방열형 전자총에 속동효과를 부여하는 가장 간단한 방법은 슬리이브 내부에 수용되는 히이터를 항상 일정하게 예열시켜서 전자총의 순간동작을 가능케 하는 것이나, 이 방법은 텔리비젼을 껏을 때도 예열전류가 흐르므로 전력소모가 크다는 결점이 있다.The simplest way to impart a speed effect to a heat-dissipating electron gun is to always warm up the heater inside the sleeve to enable instantaneous operation of the electron gun.However, this method consumes power because preheating current flows even when the television is turned off. There is a drawback to being large.

그러므로 상기한 속동형보다는 다소 스타아트시간이 늦더라도 수명이 길고 전력소모가 작은 전자총을 모색하게 되었고, 그 결과로서 전자총의 초기동작 시에 슬리이브를 통한 히이터열의 손실을 적극 억제하여 전자총의 스타아트시간을 보다 단축시키기에 이르렀다.Therefore, even though the star art time is somewhat slower than the above-mentioned speed type, the electron gun with long life and low power consumption is sought. As a result, the star art of the gun is suppressed by actively suppressing the loss of heater heat through the sleeve during the initial operation of the gun. It has shortened the time.

제1도는 종래의 속동형 전자총에 있어서, 슬리이브를 통한 열방사를 억제하는 방식의 것을 도시한다.FIG. 1 shows a method of suppressing heat radiation through a sleeve in a conventional fast electron gun.

구조적으로 볼때는 서포터(1)에 지지되는 슬리브(3)의 내부에 히이터(2)가 설치되고, 또 슬리이브(3)의 상측에 열전자 방사물질이 도포되는 캡(4)가 씌워져서 다른 종류의 전자총과 다를 바 없이 되어 있으나, 슬리이브(3)의 내외주표면은 습식 수소처리 O2가 포함된 H2분위기에 열처리하는 것)에 의해 흑화되어 있어서, 히이터(2)로 부터 흡수되는 적외선이 슬리이브(3)의 밖으로 방산됨을 적극 억제하여 슬리이브(3)의 상부에 피복된 캡(4)가 단시간 내에 열전자 방사온도까지 가열될수 있게 하고 있다.Structurally, the heater 2 is installed inside the sleeve 3 supported by the supporter 1, and the cap 4 on which the hot electron radiating material is applied is covered on the upper side of the sleeve 3. The inner and outer circumferential surfaces of the sleeve 3 are blackened by heat treatment in an H 2 atmosphere containing wet hydrogenated O 2), so that the infrared rays absorbed from the heater 2 are Dissipation of the outside of the eve 3 is actively suppressed so that the cap 4 coated on the top of the sleeve 3 can be heated to the hot electron emission temperature within a short time.

그렇지만 상기한 속동형 전자총은 그 제조과정에서 몇가지 문제점을 일으키고 있어서 실용화를 어렵게 하고 있다.Nevertheless, the above-mentioned fast-acting electron gun has caused some problems in the manufacturing process, making it difficult to apply.

즉, 슬리이브(3)을 흑화처리한 후에는 표면의 흑화막에 의해, 캡(4)를 슬리이브(3)에 용접부착할 수 없게 되므로 슬리이브(3)과 캡(4)를 용접한 다음, 흑화처리하고 있다.That is, after blackening the sleeve 3, the cap 4 cannot be welded to the sleeve 3 by the blackening film on the surface, so that the sleeve 3 and the cap 4 are welded. Next, blackening is performed.

이렇게 할 경우, 캡(4)의 상면에 도포된 열전자 방사물질까지 흑화처리되어 수명이 단축되는 문제점을 낳는다.In this case, the hot electron radiating material applied to the upper surface of the cap 4 is blackened, which causes a problem of shortening the lifespan.

본 발명의 목적은 상술한 문제점을 근본적으로 해결한 속동형 슬리이브와 그 제조방법을 제공함에 있다.SUMMARY OF THE INVENTION An object of the present invention is to provide a fast-acting sleeve and a method of manufacturing the same which fundamentally solve the above-mentioned problems.

이에 따라 본 발명은 습식 수소처리공정에 의해 표면이 흑화처리된 속동형 슬리이브에 있어서, 상기한 습식 수소처리공정에서 슬리이브의 외주면에 니켈제 박형 중공관을 피복시켜 흑화막 생성이 억제되게 함으로써, 캡과 저항 용접될 수 있게 한 속동형 슬리이브를 제공한다.Accordingly, the present invention is to provide a nickel-type hollow tube on the outer circumferential surface of the sleeve in the above-mentioned wet hydroprocessing step in the fast-acting sleeve of which the surface is blackened by the wet hydrotreatment process to suppress the formation of blackening film It provides a fast-acting sleeve that allows resistance welding with the cap.

상기한 속동형 슬리이브를 얻기 위하여 본 발명은 슬리이브의 표면을 습식 수소처리하여 흑화면이 생성되게 하는 방법에 있어서, 외주에 니켈제 박형중공관을 피복하여 상기한 슬리이브와 일체로 용접시킨 다음, 통상의 습식 수소처리를 행하여 슬리이브의 내주면에만 흑화면이 생성되게 한 후, 슬리이브의 상부에 캡을 씌워 저항용접하는 속동형 슬리이브의 제조방법을 제공한다.In order to obtain the above-mentioned fast-moving sleeve in the present invention, the surface of the sleeve is wet-hydrotreated to produce a black screen, the outer periphery of the nickel thin hollow tube is welded integrally with the sleeve After the normal wet hydrogen treatment is performed to produce black screen only on the inner circumferential surface of the sleeve, a capping is provided on the top of the sleeve to provide a method of manufacturing a rapid-type sleeve in which resistance welding is performed.

이하, 본 발명을 첨부도면 제2도를 참조하여 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

제2(a)도의 도시에서 니켈-크롬계로 된 슬리이브(3)의 외주면에 니켈제 박형 중공관(5)를 삽입하여 용접으로 일체화 시킨다.In the illustration of FIG. 2 (a), the nickel-thin hollow tube 5 is inserted into the outer circumferential surface of the nickel-chromium sleeve 3 to be integrated by welding.

그리고나서 습식 수소처리를 행하여 슬리이브(3)의 내주면이 흑화되게 한다.Then, wet hydrogen treatment is performed to make the inner circumferential surface of the sleeve 3 black.

이 공정에서 슬리이브(3)은 니켈-크롬계의 물성에 의해 크롬이 산화하여 표면은 흑화면으로 된다.In this step, the sleeve 3 is oxidized by chromium due to the properties of nickel-chromium, and the surface thereof becomes a black screen.

그러나 외부에 끼워진 박형 중공판(5)는 니켈로 된것이므로 산화가 되지 않아서 흑화되지 않는다.However, since the thin hollow plate 5 fitted to the outside is made of nickel, it is not oxidized and is not blackened.

흑화처리 후에는 슬리이브(3)의 상단에 캡(4)를 씌우고, 제2(b)도의 도시와 같이 일체로 용접한다.After blackening, the cap 4 is put on the upper end of the sleeve 3 and welded integrally as shown in FIG. 2 (b).

슬리이브(3)와 캡(4)의 용접공정은 일반적인 저항용접 예컨대 스포트용접등으로 행한다.The welding process of the sleeve 3 and the cap 4 is performed by general resistance welding, such as spot welding.

상기와 같이 하여 얻어진 속동형 슬리이브는 이후의 공정에서 서포터에서 부착되어 전자총을 구성하게 된다.The fast-acting sleeve obtained as described above is attached to the supporter in a later step to form an electron gun.

이 공정에서도 박형공관을 서포터에 적항용접시킨다.In this process, the thin tube is welded to the supporter.

이상과 같이 본 발명에 의하면, 슬리이브의 외주면측 흑화가 박형 중공관에 의해 적극 억제되어, 이후의 공정에서 다른 부품과 저항용접이 가능하므로 공정 중에 캡이 보유하는 열전자 방사물질까지 흑화될 염려가 없어서 수명이 길고, 또 슬리이브 내주면측에 형성되는 흑화면으로 인하여 히이터에서 방사되는 열의 손실이 억제되어 전자총의 스타아트시간이 단축됨과 동시에 전력소모가 작은 속동형 전자총을 얻는다.As described above, according to the present invention, blackening of the outer peripheral surface side of the sleeve is positively suppressed by the thin hollow tube, and resistance welding with other parts is possible in a subsequent process, so that the hot electron radiating material held by the cap may be blackened during the process. Due to the long lifespan and the black screen formed on the inner circumferential surface of the sleeve, the loss of heat radiated from the heater is suppressed, thereby reducing the star art time of the electron gun and obtaining a fast-moving electron gun with low power consumption.
