Description
えば、正確なばね定数を有するばねを具備し、それによって均一なバイアスを再現可能でありチェック可能なやり方で設定することができる。
献する。
される加熱電流が、方向矢印75によって表される等しい長さの8つの電流路に分岐され、それによって内側穴77aの区域の「好ましい供給点」76にガイドされ、それとともに環状鍔部が接触チューブ5上に載置される(図1参照)ように配列される。2つの電極端子71、72および貫通穴73の分布およびサイズのおかげで、加熱電流は、図2にしたがって合計8つの好ましい供給点76(「8点供給」)にわたって環状鍔部7に分布される。1つの「好ましい供給点」のみを備えた環状鍔部の実施形態と比較すると、これは、結果として、内側穴77aの区域でより均一な電流密度分布になり、したがって、接触チューブ5の、したがって加熱チューブ2の区域における電流密度の均質的な水平分布になる。
