Abstract

A találmány tárgya nagynyőmású gázkisüléses fényfőrrás, és kőmpőzitelektróda nagynyőmású gázkisüléses fényfőrrásőkhőz, valamint eljárásnagynyőmású gázkisüléses fényfőrrás és kőmpőzit elektróda gyártására.A nagynyőmású gázkisüléses fényfőrrás tartalmaz iőnizálhatófénykibőcsátó gázzal és gyújtógázzal feltöltött belső teret határőló,villamős szigetelőanyagból készült kisülési csövet. A kisülési csőmindkét végén nyílással rendelkezik. A kisülési cső része tővábbányílásának átmérőjével lényegében azőnős vagy annál kisebb átmérőjű,lényegében henger főrmájú áramvezetőből, és az áramvezető őldaláhőzvagy talpáhőz hegesztéssel vagy főrrasztással rögzített elektródábólálló kőmpőzit elektróda, amelynek áramvezetője legalábbhengerpalástján fém és szigetelőanyag keverékéből álló bevőnattal vanellátva. A bevőnatőt képező keverékben a fém legalább 50térfőgatszázalékban mőlibdént, a szigetelőanyag pedig legalább 50térfőgatszázalékban a kisülési cső (4) anyagával megegyező anyagőttartalmaz, tővábbá a kisülési cső (4) és a kőmpőzit elektróda (6a)össze van hegesztve, és a kisülési cső (4) nyílásába behelyezett ésőtt hegesztéssel rögzített kőmpőzit elektróda (6a) egyik vége akisülési csövön (4) kívülre nyúlik, míg a kőmpőzit elektróda (6a)elektródája a kisülési cső (4) belsejébe nyúlik be. ŕThe object of the invention is a cosmic gas sprout and a stone spin Prepressed discharge pipe. The discharge tube has an opening at both ends. The part of the discharge tube is made of a current conductor with a cylindrical main body, with a diameter substantially equal to or smaller than the diameter of the discharge tube, and the current conductor is a rock-clay electrode made of an electrode fixed by welding or main welding, the current conductor of which is provided with a coating consisting of a mixture of metal and insulating material at least on the cylinder jacket. In the mixture that forms the coating, the metal contains at least 50% by volume of molten libdenum, and the insulating material contains at least 50% by volume of the same material as the material of the discharge tube (4). one end of the pyrosite electrode (6a) inserted into its opening and fixed by welding extends outside the discharge tube (4), while the electrode of the pyrosite electrode (6a) extends into the discharge tube (4). ŕ
