Embodiment
Following with reference to accompanying drawing, describe embodiments of the present invention in detail.Fig. 1 represents to relate to an execution mode of the resistor of band lead-in wire of the present invention.
The resistor 11 of band lead-in wire forms the conductive membrane 13 that is made of carbon film on the surface of columned ceramic matrix 12.On conductive membrane 13, be provided for the cutting groove 14 of fine adjustment resistance.Intercalation electrode cap 15 on the two ends of ceramic matrix 12, and itself and conductive membrane 13 are conducted.On electrode cap 15, fix lead-in wire 16 by weld part 17.Here, electrode cap 15 is on the surface of the iron that is processed into the cap shape, forms plated copper film and nickel plated film and makes.And lead-in wire 16 is to have formed plated copper film on the iron wire material.
As shown in the figure, the outer insulating resin layer that is coated with that the resistor 11 of band lead-in wire does not cover the common conductive membrane that resistor had 13, conductive membrane is exposed.This is because be the blanket of nitrogen that is sealed by blanket of nitrogen in the glass tube of mercury vapor lamp, thus be not coated with insulating resin layer outside not needing originally, and also be in order to prevent that outer being coated with from producing gas on the insulating resin layer.
The resistor 11 of band lead-in wire, on the surface of ceramic matrix 12, form conductive membrane 13, intercalation electrode cap 15 on the two ends of ceramic matrix, cover welding lead 16 at electrode cap, constitute after the resistor, resistor is placed in the blanket of nitrogen in 350 ℃～500 ℃ scope, heats, kept 40 minutes～5 hours, final resistor is made in the processing (heat treatment) that outgases.Handle by this high-temperature degassing, can obtain at the gas generating capacity that is heated under 1 hour the situation of state maintenance of 400 ℃ of temperature is 1 * 10
-3The resistor of hPaL band lead-in wire following, that the gas generating capacity under hot environment is few.
Above-mentioned heat treated heating-up temperature wishes to adopt curvilinear figure shown in Figure 2.At first, in about 50 ℃ of down about 30 minutes of heating, then, be heated to about 400 ℃ with 1 hour 20 minutes from 50 ℃, maintenance is one hour under this state.Then, drop to 50 ℃, finish heat treatment step with about 3 hours waiting temperatures.
Maximum heating temperature, the condition of wishing to use according to reality (in mercury vapor lamp about 400 ℃) decides, perhaps according to heating than its stricter condition.Under too low temperature, can not remove and contain gas.And it is the influence to product performance is considered in the heating more than 500 ℃, so and inappropriate.Therefore, remove and contain gas, 350 ℃～500 ℃ scope heating, relatively suitably.
Retention time, the too short time can not fully be removed the gas that comprises in the resistor, so, wish to come setting-up time according to the situation of carrying out that gas is removed.In the present embodiment, be decided to be about 1 hour, only need about 5 hours, can fully remove the gas that inside comprises even increase also.Therefore, can think that the retention time is relatively more suitable in 40 minutes～5 hours scope.
Atmosphere during heat treatment has adopted inert gas, and this is in order to prevent the oxidation that goes between.In the present embodiment, in blanket of nitrogen, heat-treat.If but could prevent oxidation, so also could heat treatment in the inert gas beyond the blanket of nitrogen.Another reason be the resistor of wishing the band lead-in wire with the glass tube of mercury vapor lamp under the roughly the same state of the condition used (in blanket of nitrogen, using) heat-treat.
To having carried out above-mentioned heat treated resistor and not carried out outer heat treated resistor and carried out the analysis that takes place about gas respectively.Its result, as shown in Table 1." the no heat treatment " of table 1 is meant on the ceramic matrix that has formed carbon film, the intercalation electrode cap, the resistor behind the welding lead does not carry out above-mentioned heat treatment, in blanket of nitrogen, be heated to 400 ℃, the gas componant and the generating capacity that under 1 hour situation of maintenance under this state, are taken place." heat treatment is arranged " of table 1 is intercalation electrode cap on the ceramic matrix that has formed carbon film, resistor behind the welding lead is heat-treated (degassing is handled) according to the mode of above-mentioned Fig. 2, then, in the blanket of nitrogen atmosphere, be heated to 400 ℃, the composition and the generating capacity of the gas that under 1 hour situation of maintenance under this state, is taken place.
The gas generating capacity of (table 1) finished product
The generating capacity of wishing gas is as far as possible near 0, but by heat treatment (degassing is handled), is heated to 400 ℃, and at the gas generating capacity that keeps under this state under 1 hour the situation, desired value is 1 * 10
-3Below the hPaL.When being confirmed, the gas generating capacity under the above-mentioned condition obtains above result.
Nonheat-treated=3.10 * 10
-3HPaL
Heat-treatment=0.66 * 10
-3HPaL
As can be seen, as shown above, it is about 1/5 by heat treatment the gas generating capacity to be reduced to, and has reached above-mentioned target.
Table 2 is to the resistor part, and the ceramic matrix, lead-in wire, electrode cap, the various piece that promptly form carbon film are not carried out above-mentioned heat treatment, have checked gas componant and generating capacity under the condition identical with the analysis in the table 1.
The gas generating capacity of (table 2) resistor each several part
And above analysis 400 ℃ of heating down, but under the situation of heating about 100 ℃, does not find that what gas takes place.That is to say that as can be seen, for example, when utilizing the heat treatment method in past of above-mentioned patent documentation 1, be arranged in the resistor in the glass tube of mercury vapor lamp, the degassing is handled insufficient.
From each table, investigated thoroughly the main component of the gas that takes place.And, as can be seen from Table 1, CO
2Generating capacity big.As can be seen from Table 2, the gas that takes place from the electrode cap is many.Can think that these gas componants are to be included in the electrodeposited coating unavoidable composition owing to the operation of the punch process of electrode cap with to the electroplating work procedure of electrode cap and lead-in wire.And, the generating capacity of every kind of composition (for example, the H that has nothing in common with each other in table 1 and table 2
2In finished product, reduce Co
2In finished product, increase).This shows that wire bonds etc. are attended by the operation of heating, to having a significant impact adhering to of gas.
The ceramic matrix, lead-in wire, the electrode cap that have formed conductive membrane have gas to take place respectively.So, it is assembled, make before the finished product, in each part stage, heat-treat also separately or together and produce effect.And as can be seen from Table 2, especially the gas generating capacity of electrode cap is up to 2.10 * 10
-3HPaL, so, only the electrode cap is carried out heat treated and also produce effect.Moreover, to ceramic matrix, lead-in wire and electrode cap whole or a certain heat-treat in advance after, it is assembled, make finished product, again this finished product is heat-treated, help to reduce gas generating capacity as the resistor of the band lead-in wire of finished product.Here said heat treated condition can adopt the condition identical with above-mentioned condition.
