Abstract:
An exposure device for non-planar substrate, a non-planar substrate patterning method using the same, and a non-planar substrate patterned by the same method are provided to prevent non-uniformity of patterns due to diffraction of ultraviolet ray by attaching a film mask on a surface of the non-planar substrate. A mask preparation process is performed to prepare a mask(100) having a non-planar substrate and a predetermined pattern(50). The non-planar substrate is coated with photoresist(150). The mask is attached on a surface of the non-planar substrate by using an adhesive, in order to surround the non-planar substrate. The photoresist layer coated on the non-planar substrate is exposed by using a rotary exposure apparatus. The non-planar substrate is a cylinder structure.
Abstract:
A method for printing a fine pattern is provided to rapidly and accurately print a fine pattern by precisely and uniformly maintaining a gap between fine patterns. A substrate is prepared which has hydrophilicity with respect to ink(50) for printing a fine pattern(30). A material having hydrophobicity with respect to the ink is deposited on a non-pattern region of the substrate so that a fine pattern printing region(20) of the substrate is made of a hydrophilic region and the non-pattern region is made of a hydrophobic region. A fine pattern is printed in ink in the fine pattern printing region. In forming the fine pattern printing region and the non-pattern region, a hydrophobic material(10) can be stamped on the substrate by using a mold corresponding to the non-pattern region.

Abstract:
PURPOSE:A manifold is provided to improve the slow movement characteristic by reducing the stick slip event of a hydraulic cylinder and to secure the long life and the high reliability by preventing the damage of a servo valve. CONSTITUTION:A single-stage manifold(2) is arranged between a servo valve(1) and a servo actuator(5) serially. A seal is located under the single-stage manifold. A two-stage manifold(17) has a main pressure supply line. Thereby, the flow of fluid is controlled. The servo valve in the single-stage manifold supplies the main pressure to be supplied through the two-stage manifold to the servo actuator through left/right passages(3,4).
