Title: High-precision optical reflecting mirror
Inventor: NAKAYAMA MINEO
IPC: G02B5/08
Filed: 1992-09-25
Abstract: PURPOSE:To prevent thermal deformation due to temp. change during processing the surface or during used, by forming a metal film as a light reflecting film on the surface of an aluminum nitride sintered body. CONSTITUTION:A flat plate of an aluminum nitride sintered body having 99.5% sintering rate with rather high porosity is used as the base body of an optical reflector mirror. A glass paste having almost same coefft. of thermal expansion is applied by screen printing and baked to form a glass layer. The glass layer is ground to make a smooth surface of 1/(10lambda) surface roughness. Then a vapor deposition film of metal aluminum is formed by sputtering on the glass layer. With this vapor deposition film of metal aluminum, decrease in reflection precision due to thermal deformation during manufacturing a reflecting mirror or during use is prevented. Even when an aluminum nitride sintered body with low sintering rate is used, a high-precision reflecting mirror can be obtd.

Title: Method for assembling clad steel blank material
Inventor: KONUMA YUKIO
IPC: B23K20/04
Filed: 1989-10-27
Abstract: PURPOSE:To obtain the clad steel which is free from surface flaws in a good joined state by interposing titanium foil in the contact surface of a carbon-contg. member to be separated after joining of a clad at the time of assembling the clad steel blank material. CONSTITUTION:The titanium foil is interposed between the required separating members of the clad steel blank material and the clad steel blank material is assembled. The four circumferences of the joint surfaces are welded and the base metal steel and the cladding metal steel are press welded by heating and welding. The titanium foil and the C in a dummy material react during this treatment and a titanium carbide structure layer is formed at the boundary face between the cladding metal and the dummy material. The titanium carbide structure layer is an extremely brittle layer and, therefore, if the resulted clad material is cut to a desired size and if the force to pull and peel the dummy material is applied to the dummy material, this layer is easily broken down and the dummy material is separated. The steel kinds of the base metal steel are not particularly limited and the cladding metal may be any of various steels, Cu, Cu alloy, Ti and Ti alloy. Carbon steels are generally used for the dummy material and spacers and the thickness of the titanium foil is specified to 0.1 to 1.0mm in terms of both of the peelability and the cost of titanium.

Title: Guided missile
Inventor: HARA HIROYA
IPC: B64C21/08
Filed: 1991-10-28
Abstract: PURPOSE:To suppress a temperature rise of a steering wing and to suppress decreases in strength and rigidity of the wing by preventing transfer of heat generated at the time of flying at a high speed to the wing. CONSTITUTION:A high pressure gas source 4 is provided in a body 2. Gas stored in the source 4 is guided to a gas discharge hole 6 provided along the front edge of a steering wing 1 via a high pressure tube 5 disposed in the body, and discharged to the atmosphere. The discharged gas forms a flow layer between the flow of the atmosphere and the wing 1. In this case, since heat in a heated boundary layer around the wing 1 is absorbed by the discharged gas itself, the temperature of the boundary layer is lowered. Since the thickness of the boundary layer is increased by the discharged gas, a temperature gradient between the surface of the boundary layer and the surface of a guided missile becomes smooth, and flow of heat is lowered. Further, the speed in the boundary layer is lowered by the discharged gas and a heat transfer rate is reduced, and hence flow of the heat to the wing 1 is decreased.
