摘要： A dense insulating thin film having a remarkably improved insulating property can be formed by a process comprising a first step of forming a first portion of an insulating thin film on a substrate by a sputtering process without exposing the substrate to a plasma or while irradiating the substrate with low energy particles and a second step of forming a second portion of the insulating thin film on the first portion while exposing the substrate to a plasma or while irradiating the substrate with high energy particles, thereby forming said insulating thin film on the substrate. The insulating property in terms of the dielectric breakdown voltage is 100 V or more as determined in a film thickness of 1 .mu.m or less and an area of 20 mm.sup.2.

摘要： A corrosion detecting probe is to be used in combination with a known electrochemical measuring apparatus for inspecting corrosion state of a steel material buried in a concrete structure. The probe comprises a container made of an electrically insulating material and having an open end adapted to be placed in close contact with a surface of the concrete structure, a cover closing the open end and made of a porous and liquid permeable material, an electrolyte liquid solution filling the container so that the cover is sufficiently impregnated with the solution, and an electrode assembly mounted within the container so as to be immersed at least partially in the electrolyte solution. The electrode assembly includes an elongated reference electrode having a free end portion at least partially immersed in the electrolyte solution, a counter electrode having an electrode plate of a symmetrical configuration with respect to the free end portion of the reference electrode and distanced therefrom, and a current flow line control electrode having an electrode plate of a symmetrical configuration with respect to the free end portion of the reference electrode and disposed in a same plane as the electrode plate of the counter electrode at a distance therefrom.
