Title: Lithographic technique using laser scanning for manufacturing electronic component, etc.
Inventor: SHIYAIAMU CHIYANDORA DASU
IPC: G03F7/20
Filed: 1990-06-19
Abstract: PURPOSE: To obviate the occurrence of undercuts by executing irradiation with a laser by scanning of plural sets of work pieces and executing the irradiation of the ensuing respective sets in superposition on the immediate previous sets including plural times of scanning that the respective sets cross the allocated regions of the work pieces. CONSTITUTION: Masks 15 of reflective materials at the wavelength of the lasers 26 to be used are arranged on the surfaces of the work pieces 10 and are then irradiated with the lasers 16, by which the unmasked work piece materials are removed. Etching is executed by immersing the work pieces 10 into a liquid bath transparent to the laser radiation 16. In such a case, a laser scanning protocol on one surface includes a stage for exposing the surface of the material to the laser radiation 16 of the certain pattern through a reflective mask layer 15 and removing the material corresponding to openings 20 to allow the material of the certain pattern to remain. The laser radiations 16 are impressed by irradiation of plural overlaps in order to complete the perfect scanning to cross the work pieces 10. After the scanning of the sets, the scanning of the ensuing respective sets is executed in superposition on the preceding sets. As a result, the rapid removal of the unnecessary materials is made possible and the occurrence of the undercuts is averted.

IPC: H01Q1/22
Filed: 1985-07-22
Abstract: PURPOSE:To improve the efficiency of antenna by using an air-core loop antenna and making a cross sectional area in a direction at a right angle to the coil axis nearly coincident with the maximum cross sectional area of a helmet. CONSTITUTION:The cross sectional shape of the loop antenna 20 in a direction at a right angle to the axis of the coil 21 is made nearly coincident with the cross sectional shape of the outermost circumferential shape of the helmet 10.

Abstract: PURPOSE:To prevent the internal defect occurring in the nonuniformity of beads and to improve the quality of a joint in multi-layer welding of a horizontal wall and a vertical wall which intersect orthogonally with each other, by laminating the beads which extend in a transverse direction from the vertical wall and are increasingly narrower from the 1st layer toward the final layer. CONSTITUTION:The weld line of a horizontal wall 3 and a vertical wall 4 is stored and a weaving width is set according to a leg length. While a welding torch 5 is subjected to weaving at the above-described set width, the welding of the 1st layer is accomplished along the stored weld line and a flat bead 11 of a prescribed width extending in the transverse direction from the wall 4 is formed. The extent of pulling up the torch 5 and the width of the new weaving are determined by arithmetic processing and the welding of the 2nd layer is carried out, thereby forming the bead 12 of the 2nd layer which overlaps on the 1st layer bead 11, extends in the transverse direction from the wall 4 and is narrower than the bead 11. The torch 5 is pulled upward and the welding of the bead 13 of the 3rd layer and succeeding beads is accomplished while the weaving width is gradually increased.
