IRRADIATING DEVICE OF ELECTRON RAY

摘要

PURPOSE:To eliminate the need for an inert gas for shutting off air by heating an object to be irradiated and the periphery thereof to evaporate the solvent, etc. in the paint on the coated surface of said object thereby enabling shut- off of the air. CONSTITUTION:The part of an object A to be irradiated with an electron ray and the periphery thereof are heated by a heater and a solvent or a volatile monomer evaporates quickly from a paint coated film A'. The film A' is shut- off from the air. An electromagnetic wave in a range from visible light to far IR ray is radiated from said heater. The need for the inert gas for shutting-off the air is eliminated by the above-mentioned device.
