Title: Gas pressure welding method for dissimilar materials
Inventor: OISHIBASHI KOJI
IPC: B23K20/00
Filed: 1988-09-02
Abstract: PURPOSE:To easily obtain a joint excellent in tensile strength and bending properties by subjecting an austenitic steel member and a ferritic steel member to gas heating and pressure welding by interposing insert material of two-phase stainless steel between the joining end faces thereof. CONSTITUTION:The austenitic steel member and the ferritic steel member are heated to the proper temperature by gas heating and then, welded by pressure. In the above-mentioned gas pressure welding of dissimilar materials, the insert material made of two-phase stainless steel is interposed between the joining end faces of both members as mentioned above to carry out gas heating and pressure welding on these members. Stainless steel displaying the superplastic deformation behavior in the gas heating and pressure welding temperature is desirable as the above-mentioned two-phase stainless steel. In addition, material having 0.5-5.0mm thickness is suitable as the above-mentioned insert material. By this method, the joint excellent in both tensile strength and bending properties can be obtained even under pressure welding conditions with the low heating temperature and little upset quantity.

Title: Cooling method for nozzle of supersonic wind tunnel
Inventor: KUROSAKA TOSHIO
IPC: G01M9/04
Filed: 1991-08-29
Abstract: PURPOSE:To decrease the costs of the apparatus of a cooling system and the operation for the nozzle of an supersonic wind tunnel, which forms the specified supersonic blow of high-temperature and high-pressure gas, by effectively cooling the inner wall of the nozzle for the high-temperature heat flux without forming corner parts and irregularities, which become starting points of heat cracks, in a cooling water flow path, preventing the burnout up to a high heat load, and decreasing the required amount of the cooling liquid. CONSTITUTION:A cooling-water flow path 1a, which is provided in the wall of a main body 1 of a nozzle, is formed in a cylindrical state, whose inner surface is smooth. A swirler 4, wherein twisted blades 4a are internally provided, is arranged in the inside part of the flow path. Thus, cooling water, which is introduced into the cooling-water flow path 1a, is formed into swirling stream. Therefore, the absolute flow speed of the cooling water with respect to the inner surface of the cooling-water flow path is enhanced higher than the axial flow at the same flow rate. The inner wall of the nozzle can be effectively cooled. The occurrence of heat cracks from the inner surface of the cooling- water flow path can be suppressed.
