Abstract

PURPOSE:To monitor the temp. of a heat evolving member by writing symbols to be printed on said member by means of printing ink which discolors by the effect of temp. CONSTITUTION:Irreversible temp. sensitive coloring ink which discolors by the effect of temp. is used as the printing ink for printing and displaying symbols 2 such as type name, lot number and the like of a heat evolving member 1 such as semiconductor electronic parts, whereby the safe operation temp. of said member is monitored at all times.
