Title: Construction method for underground continuous wall
Inventor: IKEUCHI YOSHIAKI
IPC: C09K103/00
Filed: 1988-04-25
Abstract: PURPOSE:To provide high specific gravity without impairing the traits of a stabilizer liquid by adding an inert inorganic mineral fine powder to a bentonite type stabilizer liquid as a weight increasing material, wherein the fine powder consists of an inert extra-fine powder in electrochemical terms and has a mean particle size under a certain value and a specific gravity over a certain value. CONSTITUTION:An extra-fine powder of quartz or kaolinite as one sort of clay mineral is added to a stabilizer liquid, wherein the specific gravity of the fine powder is over 2.5, or preferably over 2.6, and the mean particle size is under 5mum with the 74-mum sieve passage rate being 100% and 10-mum sieve passage rate being 85%. This extra-fine powder is collected by a dust collector from dust generated in the drying process for crushed clay in a plant for production of ceramic, fire-proof products, and clay for porcelain. The inert inorganic mineral powder has a small index of plastization and a very small precipitating speed because of its fineness, and under co-existence of bentonite in appropriate concentration, it excels in the suspension stability, and its electrochemical inertness at the particle boundaries does not cause larger viscosity even in higher concentration.

Title: Superplastic extrusion processing method
Inventor: KURIFUOODO SHII BANPUTON
IPC: B21C23/00
Filed: 1996-04-23
Abstract: PROBLEM TO BE SOLVED: To obtain a method of superplastic extrusion processing for fabricating large, complex-shaped metal alloy components of high strength. SOLUTION: In the method of superplastic extrusion processing, a strain rate and temperature are carefully controlled to keep a fine crystalline grain metal alloy of high strength within the superplastic regime. The strain rate and temperature are controlled during superplastic extrusion processing 14 so that the stresses required for metal flow are much lower than those needed in conventional extrusion. The low stress allows use of more fragile extrusion dies and thereby a thinner cross section can be formed in larger extruded components. After the superplastic extrusion processing 14, components are subjected to solution-treatment 15, stretch straightening 16 and creep-age forming 17. The resulting metal alloy components are excellent in strength, isotropy, ductility, toughness and corrosion resistance compared with conventional metal alloys.
