摘要： PURPOSE:To provide the titled mirror which forms a specular surface always beautifully even in a high-temp. atmosphere by coating an oxidation resistant metal or oxidation resistant alloy on the coated surface of a heat resistant ceramics member. CONSTITUTION:This mirror consists of a member 1 consisting of heat resistant ceramics such as quartz glass, transparent sapphire or 'Pyrex(R)' (trade name) and a specular surface part 3 consisting of the oxidation resistant metal or oxidation resistant alloy coated on the coating surface 2 of the member 1. This oxidation resistant metal or oxidation resistant alloy exhibits the oxidation resistance of about weight increase by oxidation by heating for about 100hr at about 1,000 deg.C in an atmosphere atmosphere. For example, the oxidation resistant metal is silicon, nickel, platinum, etc., and the oxidation resistant alloy is alloys such as alloy of silicon and chromium and alloy of nickel, boron and tungsten. The annihilation of the specular surface of the specular surface part 3 of this mirror 7 even in a high-temp. atmosphere is thereby obviated.

摘要： PROBLEM TO BE SOLVED: To make it possible to surely fix a lens and an image guide and to make the endoscope usable stably over a long period by adhering and fixing the lens and the image guide in the state of peeling the precoating layer of the image guide near the lens. SOLUTION: The precoating layer (consisting of, for example, an acrylic resin) 11 of the image guide 2 is peeled by a peeling agent. Next, the peeled part is washed and thereafter, the lens 7 and the image guide 2 are adhered by a UV adhesive, by which the lens 7 is adhered to the front end face of the image guide 2. An epoxy adhesive S is thereafter applied on the periphery of the lens 7 and image guide 2 adhered to a tube 12 and the adhered assembly of the lens 7 and the image guide 2 is inserted into a tube 13. The adhesive is then cured to fix the assembly. The adhesion is not the adhesion of the different materials as plastic to each other in such a manner. The change (degradation) in the adhesive power between the image guide 2 and the precoated piece by temp. conditions does not arise and the lens 7 is hardly peelable from the image guide 2.

摘要： PURPOSE:To observe light from flame right under an electrode through a transparent pressure resistance aperture board by forming an engine inside observation hole at a housing where the electrode is inserted and fixed, and fixing the board at the inner end of the hole. CONSTITUTION:An electrode 1 is inserted into a hole 18 formed being deviated at the position slightly spaced from the center O of the end 17 of a housing 2. The housing 2 is provided with an engine inside observation hole 5 where an end 4 of an image guide 3 is inserted, and the axial core C of the hole 5 is inclined in the direction to open the basic end side by a specified angle thetaa with respect to the center O. The axial core P of an electrode 1 is also inclined in the direction to open the same similarly by a slight angle thetab. The hole is formed to the recess 20 of the end 17. Further a transparent heat resistant and pressure resistant aperture board 7 made of sapphire and the like is closely fixed at the inner end 6 of the hole 5.
