Abstract: A process for producing a MC-type conductive filler includes treating minute metallic particles with a coupling agent, preparing an oil phase of the coupling agent-treated minute metallic particles and a reactive substance A, the reactive substance A directly contacting the metallic particles. Then, an aqueous phase is prepared having a reactive substance B, which is capable of reacting with the reactive substance A, dissolved in water. Thereafter, the oil phase is dispersed in the aqueous phase to form a suspension. In situ reaction of the reactive substances A and B is then caused by applying heat to the suspension or adding a catalyst to the suspension. This forms a coating of a thermosetting insulating resin on the surface of the minute metallic particles. Alternatively, the reactive substance B may not be used.

Abstract: In an authentication apparatus, at least one authentication program corresponding to an authentication method of the user's choice executes an authentication process based on data received from a sensor unit and personal feature data. An authentication determination program calculates a comprehensive authentication level value of such an authentication method on the basis of authentication evaluation data. When the calculated comprehensive authentication level value has exceeded the predetermined authentication level, the authentication determination program determines that authentication has succeeded; otherwise, the program determines that authentication has failed.
