摘要： PROBLEM TO BE SOLVED: To dispense with nickel plating with respect to cooling blades and reduce consumption of electroless nickel plating solution so as to achieve an electronic tube effective in view of the cost and environment of the earth, and further, fixingly solder the cooling blades at a low temperature so as to prevent the degree of vacuum from being decreased at a high temperature. SOLUTION: An electronic tube comprises a cylindrical anode 11 made of copper having a filament electrode and a grid electrode housed inside an inner space thereof, and cooling blades 18 made of aluminum or an aluminum alloy disposed at the outer peripheral portion of the cylindrical anode 11. In this case, there is provided a thin plate 19 made of copper welded at one surface 19a thereof to the cooling blades 18 and welded at the other surface 19b thereof to the cylindrical anode 11.

摘要： PURPOSE:To stabilize the operation of the captioned tube so as to obtain its high reliabliity by comprising a metal chrome layer on the inner surface of an anode and a chrome oxide layer on the surface of the metal chrome layer to prevent unnecessary temperature rise within an electron tube. CONSTITUTION:Firstly, the inner surface of an anode 21 made of copper is processed to have a pear-skin by meas of a liquid honing. Next, chrome plating of 20mum in thickness is carried out on the surface processed with the pear skin in given conditions. An anode used for an electron tube which is provided with a metal chrome layer 22 on the inner surface is completed by drying it by means of hot air following to a water washing and a hot water washing after the completion of the plating. A metal sealing dish 4 etc. is brazed to the anode. A chrome oxide layer 23 is generated on the surface of the metal chrome layer by carrying out such a brazing in a humidified hydrogen atmosphere. Whereby, it is possible to stabilize the operation so as to obtain high reliability because unnecessary heat energy is efficiently absorbed into the anode to enable it to be radiated outside the tube by means of heat radiation fins etc.
摘要翻译：目的：为了稳定标题管的操作，通过在阳极的内表面上包含金属铬层和金属铬层的表面的铬氧化物层来获得高可靠性，以防止不必要的温度升高电子管。构成：首先，通过测量液体珩磨将由铜制成的阳极21的内表面加工成具有梨皮。接下来，在给定条件下，用梨皮处理的表面进行厚度为20μm的镀铬。用于电子管的阳极，其在内表面上设置有金属铬层22，通过在完成电镀之后进行水洗和热水洗涤后的热空气进行干燥来完成。金属密封盘4等钎焊到阳极。通过在加湿氢气氛中进行这种钎焊，在金属铬层的表面上产生氧化铬层23。由此，由于不必要的热能被有效地吸收到阳极中以使其能够通过散热片等被辐射到管外，因此可以稳定操作以获得高的可靠性。
