Patent ID: 7764158

Claim:
An electromagnetic induction type processing apparatus, comprising: a coil configured to generate an electromotive force from a magnetic field supplied from an outside; and a functional device configured to operate with the electromotive force and containing conductive substance having a conductivity with which an eddy current to be generated in the conductive substance by the magnetic field supplied from the outside is suppressed such that the lowest electromotive force for operation of said functional device is assured regardless of a magnetic field generated by the eddy current and acting in an opposite direction to that of the magnetic field supplied from the outside, wherein said functional device includes non-uniformly distributed electrodes electrically connected thereto, the non-uniformly distributed electrodes having a notch configured to suppress the eddy current generated in the non-uniformly distributed electrodes, and wherein said notch is arranged within the non-uniformly distributed electrodes so that the notch does not affect an ability of the functional device to perform a desired function.
