ELECTRIC KILN FOR CERAMIC ART

摘要

PROBLEM TO BE SOLVED: To provide an electric kiln for ceramic art in which energizing through heat-generating members changes the temperature therein, and which is safer and quieter than conventional ones. SOLUTION: Semiconductor switching elements are provided to control the temperature of the heat-generating members of the electric kiln for ceramic art. A mechanical relay circuit is also provided to control the start and termination of energizing. COPYRIGHT: (C)2005,JPO&NCIPI
