Abstract

PURPOSE:To shorten the temperature increasing and decreasing periods in comparison with the prior art thanks to the negative heat conductivity of sapphire as to make possible the printing operation of high speed and low power consumption by making the substrate of a heat-sensitive printing head of sapphire.
