Abstract: PURPOSE:To reproduce a stable reproducing image by inserting a regenerative FM signal reproduced by a pair of other heads into a no-signal field of a regenerative signal. CONSTITUTION:Signals regenerated by each head 21a, 21b and 22 are inputted to amplifiers 31a, 31b and 32, respectively through rotary transformers 1-3, and a regenerative FM signal (d) amplified by an amplifier 32 is inputted to signal switches 2, 42. Also, the regenerative FM signal amplified by the amplifiers 31a, 31b is switched by a switching signal (b), and a signal switches 1, 38 output a regenerative FM signal (c). The regenerative FM signal (c) and the regenerative FM signal (d) are inputted to the signal switches 2, 42, switched by a switching signal (a), become continuous regenerative FM signals, and inputted to a signal processing circuit 44. In such a manner, a regenerative video signal (e) inputted to a clamping circuit 54 is a continuous video signal, therefore, no sag is generated in the signal passing through the clamping circuit 54.

Abstract: PURPOSE:To prevent a close contact property and the like from being deteriorated and to eliminate the electric damage by a method wherein ions of a gas of a material to be used as a thin film are extracted, they are neutralized before they reach a substrate to be treated and the substrate to be treated is irradiated with electrically neutral radicals. CONSTITUTION:A vacuum chamber 1 is evacuated to produce a vacuum by using a vacuum pump; a material gas to be used as a thin film is made to flow from a gas introduction port 4; microwaves 9 are applied from the upper part of the vacuum chamber 1. Then, a so-called ECR plasma 9 which is resonated with the magnetic field of an electromagnet 3 is generated. A negative potential is applied to an ion-extraction electrode 6. Ions are extracted to the side of a substrate 5 to be treated; immediately after that, they are transformed into electrically neutral radicals or atoms by using a neutralizer 7. While the generated radicals or atoms are keeping, to a certain extent, their kinetic energy or their motion direction at the time when they have been extracted, they rush into the substrate 5 to be treated. Radical particles contribute mainly to the formation of a film by a chemical reaction.
