Abstract

PURPOSE:To remove temperature ununiformity on the electron emissive material surface of a cathode in the structural manufacturing process of a support device and improve the productivity of a cathode sleeve and the support device by integrally molding them from the same member. CONSTITUTION:A raw material sleeve 21 made of an nickel chrome alloy with the same diameter and material as those of a cathode sleeve 24 is prepared first. Then this raw material sleeve 21 is sent and revolved along a cut line 22 and is cut by laser beam so as to alternately form a recess and a protrusion. Subsequently the sleeve is revolved along a cut line 23 and is cut by laser beam. A member that integrally form a cathode sleeve 24 and a support device 27 can be obtained by such a process. Since both the cathode sleeve 24 and support device 27 are cut and molded integrally from the raw material sleeve 21, the support device 27 need not be provided separately. Besides, any process for welding the cathode sleeve 24 to the support device 27 is not required and any fault will not caused by welding.

Description

[Detailed description of the invention] [Invention! Technical Field] The present invention relates to an Fi-linked shu-sakaki body and a method for manufacturing the same≦2.

[Technical background of the invention and the stakes involved]

For example, when the TV receiver is turned on, it turns on and off as soon as possible, and the imtlol becomes stable.
It is desirable to reach Recently, in order to satisfy this requirement, the conventional stand-by system C2, which has been changed to various intermediate points, has been replaced by the shielding system.

This fast-moving IJJ11!1111I! For the structure, for example, a sleeved nichrome alloy is used, and the surface of the #jIk & structure is blackened by blackening in a wet water furnace, and the thermal emissivity is reduced to 0, for example, compared to 0.2 of nickel. .8 g2, increasing the dispersion at steady operating temperature, and
By inputting a large heater power commensurate with this increased heat loss (for example, about 4 times the conventional power in the case of a diode and valley stack), a rapid increase in am is made possible.

[Overview of the invention]

Gentleman, this lightening is the insertion and expansion of the base metal that can form an electron radioactive substance at the top, 11! The first sleeve is in contact with the first sleeve 1, a plurality of supports have one end fixed near the lower end S of this cathode sleeve, and a good cathode support tube has the other end fixed to the waste 942. The interlocking cathode structure P2 is characterized in that the cathode sleeve and supporter are integrally molded from a regular material, and the cathode sleeve and supporter are cut out from a molded M material sleeve and blackened. rear,
After inserting the base metal and expanding it, bend the first-order support with S contact from the circumferential direction, and make the free end of this support 1.
lIl! i Consists of the process of disassembling the shoulder part of the support tube, cutting out the sleeve and supporter, making contact between the base metal and the sleeve from the horse direction, connecting the supporter to #& the support tube oms.
OS* is performed using laser light.

[斃@O Example]

Next, an example of a misfire is shown in Figure th-ku mini aW! A.

First, as shown, prepare the cathode sleeve described above and the raw material sleeve made of a nickel-lipid alloy of F11N quality. Next, this raw material sleeve is cut with a laser light (-) along the cutting edge @C, and the JK material sleeve is fed and rotated at the same time so that one uneven portion is formed alternately.Next, two cuts are made. Rotate along a line and cut with light.

Through such process @1, a skin member can be obtained in which the cathode sleeve and supporter are integrally formed.

By subjecting this 0111# to a temperature of 1050°C in a water-filled airflow with added water, the cathode sleeve and supporter were formed by oxidizing the tar in the nickel-relem alloy and causing the inner and outer surfaces to oxidize. Blackened 0 Next, as shown in 3-12, the cathode sleeve - 〇 top part (24
1) Use nickel as a living body to provide an electron radioactive member on the side, and! A disc-shaped base metal containing a small amount of silicon is inserted from the direction of the arrow, and this base metal is pressurized from the thickness direction to bulge in the circumferential direction.
Not only do we press the ift base metal to the 1llIII sleeve, but we also press the 601 heavy body metal from the plate thickness direction with a preliminary l- for welding from the circumferential direction by a machine @ O race party, and weld it in the local direction C1l. By doing so, it is possible to eliminate the gap between the electrode sleeve and the base metal. This factory is simply referred to as a matchmaker or a bulge. ◇ Next, see Figure 4 1; as shown in 6; on the base metal) and - the pole sleeve - from the method of circumscribing the laser party Shinji #! Contact (241)
Perform 111III welding at Konoto l! There is no problem with the oxidized layer of the cathode sleeve. Also, there is no relationship between the base metal and the cathode sleeve, so a hole is made in the two-wheel electrode sleeve and the S contact is melted by laser light. (241) never becomes weak.

Next -; # & 5 As shown in the figure I: Supporter - with 6m sleeve - I! Connecting part (27g) Free end part (271) Near (27
b) Fold and form. In this case, the total length of the supporter (roller) is not shown in one direction in FIG.
1! ! 11 - When forming the folding run - Cut the two-way end part (271) to the required size and then cut the shoulder part (271) of the two-way end (271) as shown in Figure 6-1.
From the Ha) direction, support element (B), -pole sleeve - base metal -〇lI! Insert the solid, connect the shoulder @ (26-) ll- free end @ (27x), and connect the S contact (2
61), and finally - one substrate gold II - top two electron radioactive materials (not shown) are formed into Ik cloth to form interlocking type IIJI.
Gokusakaki body is completed.

This interlocking cathode structure Fi has the same electron gun mount as the conventional one.
It is used by inserting it into the cathode sleeve.

[Effect of Enmei]

The effects of the interlocking electrode strip manufactured by such a manufacturing method are as follows.

Since the kite 1g knee is integrally cut and molded from the raw material sleeve and the supporting element, there is no need to prepare the supporting element separately. It is not necessary, and defects caused by welding do not occur.

1 and 2, the supporter is 011111 in the conventional work type and is defective.
It) 0.05 m t -0.07 mt () Although the thickness was recommended, it was cut out from the 17 AIA material sleeve and became thinner than α02 mt, reducing the heat capacity.

The 36th supporter is made of a nickel-tar5 alloy, which has good thermal conductivity, and the second surface is blackened, so it becomes a heat dissipator and lowers the temperature by 1 degree. By setting and correcting this, it is possible to increase the heater input by adjusting the overall heat dissipation area while keeping the heater input constant. . This will result in faster interlocking. But IIIiii
illllI! When stable, the increase in heat radiation from the supporter is also added, suppressing the rise in cathode temperature.

i14, supporter # & pole sleeve #i are made of the same material,
In addition, since the surface treatment is also OK, when the heater is ignited and the temperature rises to 1 until Ashitomi-wipe is reached, the heat is 1.
The elongation based on II-12 has been corrected directly by Kokan, and as a result, there are 014 points. On the conventional side, ignite the heater 11
