摘要 |
FIELD: metallurgy.SUBSTANCE: resist film is produced at cold-rolled steel sheet to etch groove thereat. Steel sheet exposed part is made in said resist film including first area aligned with sheet width and multiple second areas extending from said first area. Note here that widths of both areas varies from 20 mcm to 100 mcm while distance from end part of one of said second areas to end of adjacent area of second areas varies from 60 mcm to 570 mcm.EFFECT: tolerable losses in armature.3 cl, 7 dwg, 1 tbl |
