Abstract
Abstract A distribution rotor is prepared by forming an electrode, having a central electrode part, an outer electrode part, and connecting parts, and fixing a resistor to both the central electrode part and the outer electrode part, subsequently severing and removing the connecting parts, and molding the assembly of the electrode and the resistor with a resin so as to form a one piece resin housing thereabout.

Claim 1
Independent Claim
106 words
A process for preparing a distribution rotor comprising: forming an electrode having an outer electrode part and a central electrode part joined together by a connecting part, joining through the application of heat a first end of a resistor to the central electrode part and joining through the application of heat a second end of the resistor to the outer electrode part, the connecting part absorbing the thermal strain and non-uniform stress caused by the application of heat, severing and removing the connecting part, and molding the assembly of the electrode and the resistor with a resin so as to form a one piece resin block.
