发明名称 PRODUCTION OF FLUORESCENT TUBE
摘要 PURPOSE:To make it possible to attach a grid electrode tightly to an insulation layer without deforming it by forming the grid electrode of magnetic material and pressing the grid electrode to an insulation layer by means of a magnetic field generating means to fix it to a substrate. CONSTITUTION:A grid electrode 5 is of material having magnetism such as stainless steel, about 50-75mum thick, and formed into a desired form by etching. On the lower side of a substrate 1 is disposed a permanent magnet 6 as a mag netic field generating means, and by putting the grid electrode 5 on the top surface of an insulation layer 3, the grid electrode 5 is pressed to the side of the insulation layer 3 by attraction force of the magnet 6, with its position fixed stably. Then, using a fixing material 7 consisting of glass of a low fusing point, the grid electrode 5 is fixed on the top surface of the insulation layer 3.
