In the present invention, by subjecting a substance to be treated such as a material, animal, fiber, plant, fish, soil, metal, etc. to a variable electric field, the physical properties of various substances can be modified with high efficiency or with a simple device and low energy consumption. Improve. The present invention comprises an AC power supply having a terminal grounded and an LC resonance circuit connected in series to the other non-grounded output terminal of the AC power supply, and the other end of the LC resonance circuit as an output terminal. A power supply device that outputs a superposed wave vo of an output voltage v of the power supply and an induced electromotive force v ′ induced in the LC resonance circuit by an external electromagnetic wave, and is connected to the output terminal of the power supply device via a lead wire. It consists of a conductive electrode plate fixed in contact with the treated substance or in the vicinity of the treated substance, and the electric field fluctuation is caused by changing the potential of the conductive electrode plate by the output voltage of the superimposed wave from the power supply device. And subjecting the material to be treated to a varying electric field to modify or improve its physical properties.本発明は、料、動物、繊維、植物、魚類、土壌、金属等の被処理物質を変動電場内にさらすことにより、簡単な装置と少ない消費エネルギーでもって各種物質の物性を高能率で変性若しくは改善する。 本発明は、端子を接地した交流電源と、当該交流電源の他方の非接地側出力端子に直列に接続したＬＣ共振回路とからなり、当該ＬＣ共振回路の他端を出力端子として、前記交流電源の出力電圧ｖと外部電磁波により前記ＬＣ共振回路に誘導された誘導起電力ｖ’との重畳波ｖｏを出力する電源装置と、当該電源装置の前記出力端子にリード線を介して接続され、被処理物質に接触固定若しくは被処理物質の近傍に固定した導電体製電極板とから構成され、前記電源装置からの重畳波の出力電圧により導電体製電極板の電位を変動させて電場変動を生じさせ、被処理物質を変動電場にさらしてその物性を変性又は改善する。
