摘要： A method of fabricating a gas sensor which comprises a substrate; a buffer layer coated on the substrate; at least one gas sensing layer arranged on the buffer layer; a pair of electrodes disposed on the gas sensing layer; and a catalytic layer coated on the gas sensing layer. A spin coating process is performed, using centrifugal force, to form the layers which are thin and evenly deposited on the substrate. The gas sensing layer of the gas sensor is formed before forming the electrodes of the same such that the heat treatment thereto can be carried out at 800.degree. C. which is much higher than the conventional temperature of 600.degree. C. The bonding of the gas sensing layer to the substrate is thereby much stronger than the conventional gas sensor.

摘要： A new type of corona discharging apparatus. The apparatus revealed is equipped with a pair of thin electrodes which are edge-to-edge parallelly arranged, and bewteen them is an air gap. It is characteristic of this apparatus that the equipped electrodes are allowed to reciprocate along a definite path within a desired distance. By using the apparatus, corona discharge on polymer film can be performed, either in a still or moving state, for a considerable length of time without causing dielectric breakdown. One of the practical applications of this invention is poling of stretched PVDF (polyvinylidene flouride) films to gain high piezolelectric activity with high production yield.
