Abstract: front page image
(EN)A first signal path comprises one or a series-arranged plurality of coils (21, 22) which are connected with the output of an amplifier (31). A second signal path comprises the same number of coils (23, 24) as the coils of the first signal path, said coils (23, 24) being arranged in series and connected with the output of a second amplifier (32). Linking paths comprise capacitors (25, 26, 27) and link the first signal path and second signal path at both ends (301 to 306) of the mutually corresponding coils (21 to 24) in the first signal path and second signal path. An SW control unit (3) changes over a switch (400) to a contact (402) when a signal is input from the amplifier (31), and changes over the switch (400) to a contact (401) when a signal is input from the amplifier (32).
(FR)Un premier trajet de signal comprend une ou plusieurs bobines (21, 22) agencées en série qui sont connectées à la sortie d'un amplificateur (31). Un second trajet de signal comprend le même nombre de bobines (23, 24) que le premier trajet de signal, lesdites bobines (23, 24) étant agencées en série et connectées à la sortie d'un second amplificateur (32). Des trajets de liaison comprenant des condensateurs (25, 26, 27) relient le premier trajet de signal et le second trajet de signal aux deux extrémités (301 à 306) des bobines (21 à 24) se correspondant mutuellement dans le premier trajet de signal et dans le second trajet de signal. Une unité de commande SW (3) permute un commutateur (400) sur un contact (402) si un signal est émis par l'amplificateur (31), et permute le commutateur (100) sur un contact (401) si un signal est émis par l'amplificateur (32).
(JA) 第1信号経路は、増幅器(31)の出力に接続された一つ又は直列に並んだ複数のコイル(21、22)を有する。第2信号経路は、第2増幅器(32)の出力に接続され直列に並んだ第1信号経路のコイルと同数のコイル(23、24)を有する。連結経路は、コンデンサ(25、26、27)を有し、第1信号経路及び第2信号経路における互いに対応するコイル(21~24)の両端(301~306)で第1信号経路と第2信号経路とを連結する。SW制御部(3)は、増幅器(31)から信号が入力された場合スイッチ(400)を接点(402)に切り替え、増幅器(32)から信号が入力された場合、スイッチ(400)を接点(401)に切り替える。
