Description
L1.C3.ω0 2=1、式中、ω0=2πf0
ピーク幅は、比L1/R1と関連する。値L1/R1が大きいほど、共振ピークが狭くなる。
Z1≒ZG
であるときに最大である。
a.抵抗R1とインダクタンスL1を有し、ツール回路とも称される誘導加熱回路を備えた金型本体であって、前記ツール回路は、金型本体の閉じた空洞の内部に延びるインダクタを含む、金型本体と、
b.ツール回路を高周波電流発生器に接続する接続手段と、
c.ツール回路と接続手段との間にあり、抵抗R2とインダクタンスL2とを有し、金型本体に電流を誘導せず、前記ツール回路に接続された、いわゆる調整コイルと
を備えることを特徴とする。
本発明は、個々にまたは技術的に動作可能な任意の組み合わせで考えることができる、以下で説明する有利な形態において実施することができる。
Z1=L1/(C3.R1)
式中、C3は、調整可能なキャパシタボックス(101)の設定値である。発振回路の、得られたインダクタンス(115)は以下のように定義される。
L1 =Li−Lch
R1=Ri+Rch
図3Bにおいて、調整コイル(342)が並列に接続されている場合、回路のインダクタンスLcは、以下の関係式で与えられる。
LC=L1.L2/(L1 + L2)
i1=i2であり、i1+i2 =Q.iである。
式中、iは発生器によって供給される電流であり、Qは発振回路の品質係数である。このような構成では、回路内に調整コイル(440)を挿入することにより、発生器(100)の始動に適した品質係数、すなわち、少なくとも2に等しい係数Qを得ることと、係数Qを最小に維持して、インダクタ(415、435)に過度に高い強度で電流を流すことを回避することとの、両方が可能となる。
