摘要： PURPOSE:To perform foreign matter detection based upon variation in electric conductivity due to local compression of a pressure conductive rubber sheet caused by foreign matter sticking on a surface to be inspected by pressing the pressure conductive rubber sheet uniformly against the surface to be inspected. CONSTITUTION:An inspection plate constituted by sticking a comb tupe detection electrode 3 on a parallel plane pressure plate 2 and adhering the pressure conductive rubber sheet 4 to the detection electrode 3 is pressed uniformly against the smooth surface 1 to be inspected. If foreign matter 6 sticks on the surface 1 to be inspected as shown in a figure (C), the rubber sheet 4 abuts on the foreign matter 6 strongly at the part and the rubber sheet 4 is compressed locally, so the compressed part 7 becomes conductive to short-circuit part of the comb type electrode 3. A proper potential is applied between both terminals of the lead wire 5 of the comb type electrode 3 and variation of a current of voltage due to the short circuiting is detected to detect the presence of the foreign matter.

摘要： PURPOSE:To reduce an equipment cost by utilizing the curved surface of a light reflecting film formed when a light reflecting film having resilience and a transparent film or resin plate, glass plate, etc. are extended to a circular frame so as to face each other and a gas is sealed under pressure to the inside thereof. CONSTITUTION:A light reflecting film 1 consisting of a resin film deposited by evaporation with aluminum and a light incident side transparent resin sheet 4 or resin plate, glass plate 4' are attached to a circular frame 2 consisting of a hard resin or light metal, etc. by using a gasket in a flange type in such a way that the inside thereof is made airtight. Air or other inert gas is then forced into such assembly through a gas introducing port 5 to inflate adequately the light reflecting film. The inflation is adjusted by increasing or decreasing the slack in the stage of attaching the light reflecting film or filling of the air or the gas. When the filling of the air or the gas ends, the material to be heated is exactly directed toward the sun and is set in the focal position to start the use. The equipment cost is thus reduced.
