Abstract:
A corrosion degree measuring method capable of field measurement for intergranular corrosion, particularly the sensitization degree, of the plant's structural materials in a narrow space. The metal electrode made of a material being measured and the counter electrode to the metal electrode are immersed in an electrolytic solution. A voltage is applied to the metal electrode in the anodic direction so as to raise the potential of the metal electrode up to the passive state potential and to keep the metal electrode at the passive state potential. The passive state potential is used as a reference potential, and a pulse-like potential signal is applied to the metal electrode in the cathodic direction. At the time of the application of the pulse potential signal, a current between the metal electrode and the counter electrode is measured, and the corrosion degree of the material being measured is determined from the intensity of the current.

Abstract:
Provided is a liquid crystal display device capable of significantly reducing occurrence of a failure such as an interlayer short-circuit. In the liquid crystal device, a first layer formed of a copper film having a purity of 99.5% or more and a second layer formed of an alloy film containing copper as a main component are successively formed on a glass substrate or a substrate on which a transparent conductive film containing indium is formed. The alloy film serving as the second layer is made of an alloy containing copper as a main component, which has a higher etching rate in a wet etching process compared with that of copper. Accordingly, a patterned cross-section of the copper film having a large film thickness can be etched in a tapered shape, to thereby improve coverage of an insulating film or the like laminated on a wiring pattern.

Abstract:
In an electrical connector adapted to be interposed between two connection objects to electrically connect the connection objects to each other, a flexible conductive film, mounted on a base member, includes a flexible insulating film having an outer surface and an inner surface. The flexible insulating film is folded near a rear edge of the base member into a generally U shape with the outer surface kept on the outside. The flexible conductive film has a film conductive pattern formed not only the outer surface of the flexible insulating film but also on the inner surface of the flexible insulating film.
