The light-substance is selected depending on the purpose of use, and a specific example thereof includes a salt-based material. By properly combining the (four) light materials to greet the white light. Preferably, the thickness of the luminescent material layer is less than u, which may cause emission of π11 (four) but not more than 200908064 28 /zm. Come to the rare gas seal of the 』, 氖, etc. in the tube. The first transmission of g _ generated by the discharge electrons hits the county atom, and the ultraviolet rays. When the cold cathode fluorescent lamp is illuminated, i contains 1 to 10 Pa and the pressure of the rare gas includes the electrode 6Ti = t at the inner ends of the T light transmitting tube. The electrode of .4% to not more than 100 parts by mass can suppress the deterioration of the wire when the wire is connected to the electrode and the shapeability of the electrode such as U is very good. The tungsten smear of the knives is extremely reduced by the collision of ionized rare gases and mercury, thus giving the electrode excellent sputter resistance. Further, a trace amount of oxygen in the electrode oxidizes the interface portion of the crystal grain: the bonding of the 01 residual edge to the interface of the electric crystal grain, and the tungsten strengthening amount contained in the electrode is in this range even if the application exceeds 1 () 1 ^之\. , including = gas and mercury have excellent resistance, and can extend the cold cathode firefly. "The situation of the eight-tuck rut is included in the above-mentioned electrode range from not less than the quality of the hundred-knife ratio 3 / 〇 Up to 35% by mass. When the alloys of molybdenum, Libai J, and nickel are 'step-by-step to improve the anti-smectite properties. If the power consumption is mineralized, the cold cathode fluorescent lamp can be extended. Shou ^ edge electrode has excellent resistance to money ratio ί parent Jia is the case that the above electrode contains a range of not less than the quality of a hundred knives. 〇 5 / 〇 to not more than the mass percentage 丨. 丨〇%. :Berry, the grain recorded in the middle can be formed in a fine state, for example, the scoop can make the electric particles from. Moreover, the fine grains in the electrode make the bonding between the particles, and the sentence 200908064 avoids the electrode being exposed to rare gases and Mercury ions are splashed. The best condition is the electrode towel _ or iron content ^ _, super 0.53⁄4. If the cobalt or iron content does not exceed the quality of 100% ^ = can prevent the nickel grain from refining / 'The grain tends to form finely, so that the nickel can be obtained from the particle size obtained by the comparison method. The anti-hybridity observed under the optical microscope is in accordance with the "An Eduction t0 Meti face / ς · to (4) (issued by TheJapanS〇ciet; f〇 == Κ· K. Taiga Shuppan) The method described is prepared and amplified by an optical microscope, having 〇.8 turns, the number of particle sizes, to obtain an average particle size, and the Z-break is equal to the median point between the particle size numbers 7 and 8. Since the particle size of 25 is just due to the above The cup-shaped opening of the electrode is eroded to obtain an average of the particle control. Therefore, it is preferred that the light transmission tube and the power consumption are reduced, wherein the cup-shaped openings are opposed to each other. In the vicinity, a pair of electrodes, an ingot of the plate cuts off the member and joins the members, and the electrode is formed by cutting the circle with the self-image-like cutting of the image plate. Then, by performing a so-called; cup shape, it is easy to =, the top cover operation includes: cutting the material wiring to make it easy to select the shape of the cup, for example, the inner diameter of the cup and the lamp 2.75 mm The length is 3 to 8 inm. The shape can be 1.05 in the outer diameter. In order to connect the electrode to the external power supply, the wire is placed in the following manner: the wire is - the 3 insects = = the above electrode. The other end can be degraded by heating through the sealed light transmitting tube to the bottom surface of the electrode, which is in the case of the conductor = (10) light transmitting tube. The twisted wire is joined to the wire using the double structure by the (four) member, 200908064. The medium w wire made of steel is coated with a κ_ amount which can be effectively emitted to the outside of the light transmitting tube. During the hungry & the heat of the electrode, the sealing member will retain the rare gas and fruit = so that the above-mentioned wire passes through and has two beads in the sealing member, such as glass beads, Kovar, and the like. For example, between the fluorescent (four) layer of 'μΪΪΪ^ and the inner surface, the A-stage secret of the present invention forms a protective layer as the open π-n and force emulsified enthalpy of the cold cathode fluorescent lamp. = 合合,或与录, and the crane's dazzling ==法和:=== 绳·° lie _ block coffee because it is available ί:==ϊί above =:==3⁄4. By which the ingot can be formed For example, thickness work, the material line. After hot rolling and cold rolling, ::Special or m to 2.6 mm and improved spreadability. After this, Bo 矣 矣 A = person, fine to release internal stress top cover operation - material line, 2 ° ° ° by performing stamping forming or pole. Therefore, as a coating method, a method of smashing and separating the liquid to the surface of the electrode, and the method of spraying the liquid on the inner wall of the tube is obtained. Will be the second night body. It can be twisted, such as immersed or post-arranged in the light transmission, light material layer. This member is sealed to cause the wire to pass through the 10 200908064 light transmission tube. The backlight of the liquid crystal panel of the r-sword can be used as the cold cathode fluorescent lamp of the present invention = the cold cathode fluorescent lamp shown in the cross-sectional view. The preferred range is from U to 5.0. The pressure in the glass is decompressed to the pressure of the atmospheric pressure. ί Body, import this space. As shown in the enlarged perspective view of Fig. 2, the cup-shaped H-zone in the J' is arranged with the end-end of the cup-shaped electrode line 9 containing the above chemical composition, and each wire is guided to 3 and pulled to the glass. Passing the other end through a glass bead and an electrode such as a fluorescent lamp, containing nickel as a main component, a predetermined amount of crane, fluorescent light and visible, and having a fine structure of crystal grains, so the cold cathode 蛍tU: and has Significantly improved sputter resistance and long life. The invention will be further described in detail below by means of the exemplary embodiments. [Exhibit Example 1] A starting material is melted at a temperature not less than the melting point of nickel, which has a trowel of two: 4% nickel, 3: 3% tungsten, 25.0% bismuth, and residual non-primary impurities (such as The chemical composition of carbon, bismuth, and bismuth is 0, 3%. The melt was injected into the crucible, and the hot rolling and cold rolling were repeated to produce a cup electrode having a thickness of α2_2, followed by annealing and stamping of the pressed material, and a cup electrode of 5 mm in length and 5 mm in length. It will have the components of 丑·8 ugly. The ovar office is connected to each of the bottom portions of the electrodes to obtain the average particle size of the 20^ comparative method. The average particle diameter of the recorded crystal grains was applied to the ruptured electrode having the 11 200908064 2.0 mm read hole at a thickness of about 18 mm to be disposed in the broken tube. Both ends of the tube which is fusion-bonded to the Kovar wiring are formed by the broken beads so that the openings of the electrodes are opposed to each other, and the glass mercury and the rare gas are sealed, and the Kovar wiring passes through the glass beads. Thereafter, the obtained two cold cathode fluorescent lamps were introduced. From the consumption of the cup portion ^^ said 'after the tube current l〇mA illumination, ^, the cup shape from the electrode is good. Based on the following criteria. Estimate the anti-hybridity.
