摘要： PROBLEM TO BE SOLVED: To sufficiently secure strength by enclosing a core material formed of a metal having a higher strength than aluminum into the inside of a member. SOLUTION: This architectural member 30 is constituted of a pipe 32 formed to have a substantially square section and a hollow inside and a tabular connection part 34 formed to project outward from an arbitrary face of the pipe 32. The member 30 is integrally formed of casting aluminum as a whole while joining the pipe 32 to the connection part 34. Core members 33, 35 are enclosed in the pipe 32 and the connection part 34. A square steel pipe made of iron or stainless steel is used for the core member 33 in the pipe 32 and a tubular steel plate made of iron or stainless steel is used for the core member 35 of the connection part 34. In this way, the ends of the core members 35, 35 formed in the casting aluminum 36 are protruded outward. Even mutual members made of casting aluminum 36 can be favorably connected while securing the strength.

摘要： PROBLEM TO BE SOLVED: To efficiently and properly peel off a film adhered to the glass part of a CRT to provide the glass part as a new glass raw material at a low cost. SOLUTION: This method for removing a film adhered to the glass part of a CRT comprises a process for crushing the glass part of the CRT having adhered film and a blast treatment process for stirring the obtained glass pieces, transferring the glass pieces in a constant route, and simultaneously blasting a grinding material to peel off the film pieces adhered to the glass pieces 80. The blast treatment process is preferably a low pressure blast treatment process comprising adding the abrasive to a low pressure high speed air flow generated from a low pressure air-generating source 30 whose exit pressure is 0.3-1.2 kg/cm2 (gauge pressure) and blasting the mixture to the glass pieces 80.

摘要： PROBLEM TO BE SOLVED: To improve workability while conducting sufficiently deep engagement. SOLUTION: In the connection structure of roof boards 6, in which connecting pieces 7, 7 are folded back to the underside sides at both end sections, a dainage member 2, in which a drain gutter 1 is formed in the eave ridge direction in a U-shaped sectional form, is arranged on a roof foundation 10. A fixing body 4 is fixed onto the roof foundation 10 on one side of the drainage member 2. A movable body 5 is installed to the fixing body 4 in a freely approachable and separable manner while holding the drainage member 2. A drawing means 21 moving the movable body 5 by the revolution of a screw is mounted. A vertical piece 22 abutted against the side wall of the drainage member 2 and latching pieces 23 latching the connecting pieces 7 are formed to each of the fixing body 4 and the movable body 5. The movable body 5 is drawn near to the fixing body 4 side by the drawing means 21, and the connecting pieces 7 are latched by the latching pieces 23 while the vertical piece 22 is abutted against the side wall of the drainage member 2.

摘要： PURPOSE:To develop a superstainless steel clad stainless steel sheet having excellent corrosion resistance by subjecting one side or both sides of a stainless steel as a base metal to explosive welding by a superstainless steel with a cladding material, executing hot rolling or furthermore subjecting it to cold rolling and annealing. CONSTITUTION:The surface of a base metal constituted of the slab of an austenitic stainless steel or a ferritic stainless steel is finished into a smooth one by scarfing or the like to remove away adhered scales. Next, one side or both sides of this base metal are clad with a cladding material contg. an austenitic superstainless steel contg. =2000m/sec exploding rate. Next, this clad material constituted of the base metal and cladding material is heated to 950 to 1250 deg.C, is subjected to hot rolling and is moreover subjected to cold rolling and annealing at need.

摘要： PURPOSE:To broadly set conditions for hot rolling and cold rolling operations by joining an Ni alloy which is a cladding metal and a stainless steel which is a base metal by an explosive welding method. CONSTITUTION:An explosively welded slab has a mild hardness distribution near the boundary and, therefore, the conditions for the hot rolling and cold rolling operations are widely settable. The range of the conditions for production is widened and further, boundary peeling and shape defect at the time of rolling do not arise. Workability and rollability are improved by incorporating Cu into the Ni alloy which is the cladding metal. Corrosion resistance is further increased by incorporating Cr and Mo therein. The rollability is greatly improved if the main chemical compsn. of the Ni alloy which is the cladding metal is composed of 60 to 70wt.% Ni and 30 to 40wt.% Cu.

摘要： PURPOSE:To avoid thermal deformation in a connecting place, avoid leakage of water to an attic, and heighten workability by making thermal expansion and thermal contraction easily allowable in the eaves ridge direction while carrying out stable connection in connection of roof materials. CONSTITUTION:A connection member 4 extending over the full length in the eaves ridge direction is fixed in a connecting place between roof materials 2a and 2b in roof backing 1. The roof material placing parts 5 and 5 are formed on the connecting member 4. The parts 6 and 6 to be connected of the end parts of the roof materials 2a and 2b are placed on the roof material placing parts 5 and 5. A short piece-shape connecting metal fitting 7 is erected between both these parts 6a and 6 to be connected. The connecting metal fitting 7 is installed on the connecting member 4 by an installing means 8. The parts 6 and 6 to be connected of the roof materials 2a and 2b are sandwiched by the connecting metal fitting 7 and the connecting member 4. The connecting member 4 is slidably pressed and held in the eaves ridge direction by presser metal fittings 33... on both width directional sides.

摘要： PURPOSE:To secure qualitatively excellent characteristic by joining a discard material on the side titanium layer of a titanium-clad plain steel slab and removing the discard material after hot rolling. CONSTITUTION:A base material is taken as, for example, a plain steel contg. >=0.08wt.% C. The titanium-clad plain steel slab is formed by joining this base material and titanium as a cladding by an explosive welding method. After hot rolling the composite material of the titanium-clad plain steel which is the discard material joined on the side of he titanium layer of this slab, the material is removed with scale. With this discard material, the generation of an oxide film and hard layer due to oxygen intrusion into titanium before hot rolling and at the time of hot rolling the composite material is prevented. And, after removing the discard material, cold rolling is executed. Plain steel is desirable as this discard material and 5% Cr-steel, low alloy steel contg. Si, etc., are adopted. Hot rolling is executed at >=800 deg.C of a solution heat treatment temp. In this way, burdens of equipment and finance are reduced.
