Abstract: An inspecting device for inspecting a thin film coating material applied to a material being treated such as glass includes a projector and a photoreceptor disposed across the material being treated, a manipulator for enabling relative movement of these projector and photoreceptor along the coating material applied to the material being treated, and an electric circuit part for producing a control signal when output of the photoreceptor exceeds a specified value.

Abstract: A coating device comprises a liquid composition supply unit for continuously supplying a liquid composition at a fixed rate, and coating unit for applying the liquid composition to a surface of an article to be coated, the coating unit comprising a coating head composed of a coating member mounted on a supporting frame pivotally mounted to the head and connected to the liquid composition supply unit, and a driving unit for moving the coating unit along the surface of the article to be coated. A preferred embodiment of the device includes an anti-curing unit for preventing curing of the liquid composition on a surface of the coating member, comprising an anti-curing tank provided with an opening through which the coating unit may come in and out of the tank and a shutter which is adapted to open and close the opening. The coating device is particularly useful for applying the liquid composition to an article with a three-dimensional curved surface.
