JPS6444440A - Method for applying resist on cylindrical body - Google Patents

Abstract

PURPOSE:To improve the dimensional accuracy of the coated film of the resist by positioning the cylindrical body by inserting a needle body therein, and then discharging a very small amount of the resist in the neighboring of the cylindrical body while rotating said body by bring it into contact with a rubber belt. CONSTITUTION:The needle body 22 is inserted into the hollow part of the cylindrical body 1, and an arm 27 is lowered by operating an air cylinder 28, thereby bringing the cylindrical body 1 into contact with the rubber belt 24. Then, a pulley 25a is rotated in a direction of (b) by rotating a motor 26 whereby the belt 24 is moved, and the cylindrical body 1 is pressed to the needle body 22 to rotate said body. Subsequently, for example, the top 10 of a pipe with a very small diameter is installed at the position apart from the center line of the cylindrical body 1 by a distance (l1) and also from the peripheral surface of said body by the distance (l2), and then, the very small amount of the resist solution is discharged on the surface of the cylindrical body to form a strip body 42, and then is spreaded to the both sides of said body 42. The distance (l2) and (l1) which control the height of the strip body 42 are adjusted suitably by the resist solution, and the distance (l3) between the end surface 32 of a support 23 and the needle body 22 is adjusted with high accuracy.
