Title: Device and method for induction heating, and induction heating coil unit
Inventor: INAMI SHOICHI
IPC: H05B6/40
Filed: 2003-03-12
Abstract: <P>PROBLEM TO BE SOLVED: To improve a fault in uniform heating of a member to be heated, by preventing the following phenomenon from occurring: when heating by an induction heating coil, the center of a susceptor is not heated because magnetic flux density is high on the inner fringe side of the center hole of the coil and the density becomes zero in the center portion.  <P>SOLUTION: This method is to carry out induction heating by making an induction heating coil face the member to be heated. Heating is carried out by introducing generated magnetic flux to the center of the coil by electromagnetically shielding the inner perimeter side of the center hole of the circular heating coil to uniform transmitted magnetic flux of the member to be heated in the inside area portion of the coil. An excess current is generated if a fluctuating magnetic field passes through a conductor to prevent the magnetic flux from passing through. By using this nature, magnetic shielding is carried out and the magnetic flux is introduced to the center of the coil to materialize uniform heating.  <P>COPYRIGHT: (C)2004,JPO&NCIPI
