The, such as the present invention refers to said, drive signals are always keep the DC voltage level (┏━━━━) but may be, in the present invention without DC level AC pulses changing polarity corresponds to the polarity switch or momentarily alarmingly which might be DC pulse number so ball, these pulse energy displacement difference ([...]) polarity switch and alternating square wave drive signal to a high level of contrast number entered by molten metal melted hole and energy igniters (amplitude and level changes) capable of plasma.

[42]

I.e., said driver (13) shown in the attached drawing number 3 in ball driving signal also conventional driving signal (DC voltage (┏━━━━)) unlike polarity changing AC pulses or polarity switch on without DC level becomes lower than the lower number of varying DC pulses or polar been instantaneous changes to the ball, such as conventional DC voltage is kept constant by changing an input driving signal of the driving signal without displacement difference to wave output while not made to improve contrast, of the present invention (example 1 - example 3) driving signal has a polarity change in polarity change such as free DC pulse or pulse amplitude to an alternating current having a pulse or AC DC pulse waveform change composite pulse energy displacement difference ([...]) entered by contrast to wave driving signal having high level is given an undulating (amplitude and level changes) plasma in the form of melt generate energy blood fusion body (11) and the acting, melted through blood fusion body (11) and melted portion of wave energy is performed with each other.

[43]

The chemical formula 2 is given an undulating band energy generated plasma and wave energy law rotating part (12) rotating by blood fusion body (11) is fitted to the tip action of the act, lowering the surface tension of molten portion to disintegrated, in such condition as shown in the attached drawing also 4 and 5 also, the force generated by the particles of metal powder free space that inherently deviates 30% than the same input rotational number and size of blood out fine ball supported which conditions, cooling is solidified to chamber (1) after downward in which spherical metal powder layer formed by the high pressure liquid coolant is equal to or higher number.

[44]

And, the present invention refers to also 6 as shown in the attached drawing, in the form of plasma wave blood fusion body (11) is fitted to the tip action of the number [...], act in order to make a plurality of point to point while [...] number, in each action point of wavelength at which the resonance point of a second material in the molten metal and for producing energy to induce a higher level of surface tension reduction of a clamp pivotably.

[45]

In said, action point depending on the position of wavelengths can be, according to the action of point 2 portion shown but illustrated, blood fusion body (11) as a function of rotational speed and the frequency of the correlation point can be located in blood fusion body and supplied plasma position more.

[46]

Or more, a preferred embodiment of the present invention is described in conjunction the present invention principle shown but for example, the present invention refers to the illustrated and described with this configuration and functional of the FRP limited to do things by halves.

[47]

Even other, appended claims the present invention departs from the idea of and category of a plurality of change and modified by one skilled are possible without may not only are disclosed.

[48]

Thus, the identification of the present invention evenly in a range of appropriate modification and crystal water are also will be deemed.
