Abstract: In order to provide a light heat insulating member having both an extremely low thermal conductivity and a high heat resistance in an atmosphere, in which pressure is reduced, a core member consisting of accumulated heat resisting inorganic fiber is put between a high temperature side skin member and a low temperature side skin member made of heat resisting fiber textile and these three members are tied all together in one body by sewing, using heat resisting inorganic fiber thread. It is possible to reduce the thermal conductivity to an extremely small value by adding a material having a high emissivity (SiC powder, SiC whisker) to the core member and to prevent scattering of material constructing the core member by covering side wall parts of the core member by the high temperature skin member.

Abstract: An electrical insulator coated with electrically insulating material is disclosed. An electrically insulating material is applied on a primer coat, in which the uniformity of the applied primer coat can be checked in a comparatively simple manner. A fluorescent material is dissolved in the primer solution before being applied to the component.

Points on the surface of the component where the primer defectively coats the components are optically detected from the absence of fluorescent material. Primer is then reapplied to these points.
