Abstract: In a probe apparatus comprising an inspecting device, an intermediate substrate and a probe substrate, in which the inspecting device is electrically connected to a proximal end of the intermediate substrate, and the intermediate substrate has a distal end electrically connected to a proximal end of the probe substrate, and the probe substrate has a distal end electrically connectable to a substrate under inspection, a plurality of probe substrates are electrically connected to the single intermediate substrate. When a particular probe substrate 4 is damaged, only the particular probe substrate 4 may be changed, the other probe substrates 4 continuing to be used, thereby achieving economy.

Abstract: A heat generating agent for medical waste sterilization. The agent is at least one compound selected from calcium oxide, calcined dolomite, and magnesium oxide, and at least one compound selected from sulfamic acid, sodium bisulfate, and anhydrous phosphoric acid. The present invention also provides a method for sterilizing medical wastes. The method includes the steps of subjecting medical waste to exothermic reaction between water and a heat generating agent selected from calcium oxide and calcined dolomite or to exothermic reaction between iron powder and oxygen to generate reaction heat and/or alkalinity by the exothermic reaction. The present invention provides an aparatus to be used according to the method mentioned above.
