摘要： PURPOSE:To make it possible to make bumps sufficiently thick even though in case where the number of pins is large by a method wherein, after a resist layer is etched to form recessed parts, metal layers are each formed in the recessed parts. CONSTITUTION:A bonding agent layer 11 of a prescribed width is applied on a high- heat resistant base film 10, a conductive sheet 12 is adhered and a substrate 13 is formed. A resist layer 14 is applied on the sheet 12, a pattern film is superposed and ultraviolet rays and an electron beam are irradiated to expose and cure a pattern 14b on the layer 14. This is developed, an electrolytic etching, in which there is little surface roughness, is performed and recessed parts 12a are formed in the sheet 12. An electroforming of gold is performed on non-resist parts 14a and metal layers 15 are grown in the depth direction while their growth in the horizontal direction is suppressed. After the layer 14 is removed with a solvent, a resist layer 16 is formed on the sheet 12. An electroforming of copper is performed on non-resist parts 16a. As metal layers 15 are each buried in the recessed parts 12a and the whole surface is flattened, electroforming metal layers 18 having an enough strength are formed. The metal layers 15 and 18 are transferred on an adhesion layer 21 of a carrier tape 19.

摘要： PURPOSE:To eliminate defective welding thus to improve the enclosing performance by temporarily sealing the cell cover and the cell case to stop leakage of electrolyte to the welding section thereafter sealing the cell case and the cell cover through welding. CONSTITUTION:A cell cover 2 is placed upside down to contain an insulator 7, a negative electrode 6, a separator 6, majority of electrolyte and a positive electrode 4 in this order then the remaining electrolyte is injected onto the positive electrode 4 to apply a cell case 1 from above. The open end section 1a of the cell case 1 is fastened inwardly to caulk a gasket 3 fitted over the outercircumferential edge section 2a1 of the cell cover 2 thus to pressure contact against the cell cover 2 and the cell case 1 and to seal temporarily, while the open end section 1a of the cell case 1 is contacted against the shoulder section of the outercircumferential edge section 2a1 of the body 2a of the cell cover 2 and to raser weld the contacting section between the cell case 1 and the cell cover 2.

摘要翻译：目的：通过在磁记录表面上提供脂肪酸金属盐的吸附层，并在吸附层上进一步提供由氟卡宾组成的润滑层，以提高磁记录介质的运行性和耐磨性。构成：设置在磁记录表面上的脂肪酸金属盐和由碳氟化合物构成的润滑层的吸附层。脂肪酸的金属是指具有高摩尔比的直链脂肪酸的金属盐。重量特别是脂肪酸的金属盐，例如月桂酸等脂肪酸的Li盐是有效的。这种金属盐的最佳膜厚在40-1000埃的范围内。所述金属盐的分子不能完全覆盖磁记录表面，并且如果膜厚度<40埃，则不允许改善耐磨性。如果膜厚度超过1000埃，则磁记录层的表面与磁记录层之间的距离大，间隔损失增加，因此不优选。诸如全氟烷基聚醚的材料作为由提供在脂肪酸金属的吸附层上的碳氟化合物组成的润滑剂是有效的，最佳膜厚度在100-3000埃范围。

The surface of the thin film layer 14 is oxidized (nitrified) by exposing the thin film layer 14 to the plasma of gaseous oxygen (gaseous nitrogen) generated with a high frequency electrode or the like. The close oxide (nitride) film layer of the ferromagnetic metal is formed well on the surface by this oxidation (nitridation). It is desirable that the thickness of the oxide (nitride) film layer 15 formed in this manner is 2-50Angstrom for the purpose of forming the protective film layer 16 consisting of the organic compound on the layer 15 with high adhesive strength.
