The obtained raw material is granulated to provide a granulated substance in which the periphery of the core material is coated with the coating material. The granulated substance is subsequently heated and expanded at a temperature without melting the core material to afford an inorganic foam. The core material is lightweight and has bubbles or is an expandable material with preferably >=100mu particle diameter. The coating material is obtained by suitably combining expandable powder with an alkaline agent, a foaming agent and other inorganic substances, etc., and preferably has a smaller particle diameter than that of the core material.

Abstract: PURPOSE:To accurately discriminate a fault location by inserting a 2nd specific signal in place of a 1st specific signal for fault supervision inputted via a transmission line and detecting the presence of an error in the 2nd specific signal. CONSTITUTION:When a supervisory pattern detection circuit 22 of a receiver 2 detects a pattern error of a supervisory pattern signal 14 at first, a control circuit 23 gives a switching signal 25 to a supervisory pattern substitute insertion circuit 21.
