Abstract
PURPOSE:To completely remove moisture in a coat in a short time by coating an antireflection coat or a protection coat on the end near the center of a tube than the vicinity near the tip along with the pinch boundary line of the tube end pinch sealing section of an inner tube. CONSTITUTION:The antireflection coat or protection coat which is coated on the the end toward the length direction of a quartz inner tube is coated on the range (indicated by the shaded portion 3) of the line segment 6 indicating the cross-sectional surface of the tube containing the end nearer the center of the tube of the pinch boundary line 5 from the line 8 separated at distance L near the tip from the pinch boundary line 5. By coating it on such a position, the moisture in the coat is easily removed through the lighting during the outer tube discharge process. When the distance L is less than 6mm, the effect is improved.
