摘要： PROBLEM TO BE SOLVED: To solve problems that sealing of a working part of a heat-resistant member by a melt-welding method is difficult because weldability of the heat-resistant material is not good, the disposition or a pressing method of an insert is sometimes difficult according to the position of a hole or a groove in the member in a diffusion-joining method of a non-melt-welding method, and joining in a semi-molten state is very difficult because the heat-resistant member has the high strength at high temperature in a case of a friction welding method.
SOLUTION: The thin layer of an insert is formed on either the working part of a heat-resistant member which is shaped by the pre-treatment, or the sealing member of substantially the same material. Then, the heat-resistant member and the sealing member are disposed on the working part via the insert. The working part of the heat-resistant member and the sealing member are joined with each other by a joining means as a primary treatment, and further joined firmly by performing the heating as a secondary treatment.

摘要翻译：解决的问题：为了解决由于耐热材料的焊接性不好而通过熔融焊接法密封耐热构件的工作部件的难题，由此，根据非熔融焊接方法的扩散接合方法，根据构件中的孔或槽的位置，插入件有时是困难的，并且半熔融状态的接合是非常困难的，因为耐热构件在摩擦焊接方法的情况下，在高温下具有高强度。解决方案：插入件的薄层形成在通过预处理成形的耐热构件的工作部分或基本上相同材料的密封构件上。然后，耐热构件和密封构件经由插入件设置在工作部件上。耐热构件和密封构件的工作部分通过作为主要处理的接合装置彼此接合，并且通过作为二次处理进行加热而进一步连接。版权所有（C）2005，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a high luminance tube such as sodium lamp having long life and low production cost, and provide a process for easy production of the lamp. SOLUTION: This invention relates to a new light-emitting tube produced by using a quartz glass or a synthetic quartz glass as a base material for the tube and forming a corrosion-resistant film on the surface and to a process for the production of the tube. The corrosion-resistant film is formed by coating the base material with a mixed solution of yttria fine particles and a silica-based alkoxide by sol-gel method, drying in air, baking in air and baking in vacuum or in an inert gas. A corrosion-resistant film composed mainly of a compound oxide of yttrium and silicon can be produced by this process. The film can be formed at a relatively low baking temperature even by using yttria.

摘要： PURPOSE:To maintain corrosion resistance by making austenite stainless steel which comes in contact with nitric acid solution, contains C: 0.02 or less, Mn: 5 or less, Si: 0.5 or less, Cr: 18-22, Ni: 0.9-1.1 times of a Cr content by weight and the residual of Fe and the like. CONSTITUTION:Austenite stainless steel having components composed of C: 0.02 or less, Mn: 5 or less, Si: 0.5 or less, Cr: 18-22, Ni: 0.9-1.1 times of a Cr content by weight and the residual of Fe and inevitable impurities is used for a part of members which comes in contact with solution concentration more than 2 normal of nitric acid concentration. The whole surface corrosion resistance is considerably improved together with the increase of a Cr content and the more an Ni content is, the less corrosion reducing quantity is even if it is immersed in corrosion environment of either Ru containing nitric acid or nitric acid.

摘要： PURPOSE:To improve the corrosion resistance, ductility and strength of a Zr alloy contg. specified amounts of Nb, Sn and Mo by subjecting the alloy to soln. heat treatment, cold working and aging under prescribed conditions. CONSTITUTION:A Zr alloy contg., by weight, 1-2.5% Nb, 0.5-2% Sn and 0-1% Mo (Mo+Nb=1.5-2.5%) is manufactured by melting. The alloy is subjected to soln. heat treatment by rapid cooling from a temp. in the (alpha+beta) phase or beta-phase temp. range. The alloy is cold worked to form a granular recrystallized structure contg. no residual martensite or Widmanstatten structure. The alloy is then aged by heating and holding at a temp. in the alpha-phase temp. range to provide a metallic structure contg. a fine precipitate.
