Title: Control plasma generating device
Inventor: HORII KIYOYUKI
IPC: H05H1/30
Filed: 1995-12-21
Abstract: PROBLEM TO BE SOLVED: To provide a stable plasma flow with little turbulence which is converged to the blowout axis by making a current flow to a high frequency coil, and making a spiral flow passing a gradually contracted tube part into a plasma. SOLUTION: An inert gas is supplied from a gas feed port 6, and the gas is blown out through an annular Coanda slit part 3. The angle θ of an inclined surface 3 is set to 5-70 deg., whereby a Coanda spiral flow which is one kind of turning flows is formed in the process of passing in a gradually contracted tube part 7 to develop a strong negative pressure sucking force in a suction port 2, and the spiral flow is consequently sucked into a device through the suction port 2 by the negative pressure sucking force. Further, the current is made to flow to a high frequency coil 8 wound on the outer wall of the gradually contracted tube part 7 to make the spiral flow passing the gradually contracted tube part 7 into a plasma. Thus, the plasma flow containing this turning spectrum component is converted to the blowout axis, and further forms a stable plasma flow with little turbulence.
