摘要： PURPOSE:To restrain deformation of a structure by joining to one part of each structural member formed mainly by common steel a dissimilar metallic material which is different in mechanical strength characteristic from common steel, such as stainless, aluminium and the like. CONSTITUTION:The structural members of a steel structure are formed mainly by common steel, and stainless steel, very low yield. point steel or aluminium alloy and the like is joined to both end portions 21,22 of the capital 11 or base 12 of each column member 10. The tensile strength of the stainless steel is about 2.3 times that of the common steel and expansion of the stainless steel is about twice that of the common steel and expansion of the very low yield point steel is about twice that of the common steel and the modulus of elasticity of the aluminium alloy is about one-third that of the common steel. Thereby the longevity of a building can be remarkably enhanced.

摘要： Stainless steel slab with a defect-free surface is produced by continuous casting using a Cu mould of which the inner wall is provided with a coating of Ni, Cr or Mo by electrodeposition. The compn. of the steel follows the relation equiv. >= O and Ni equiv. >=1.04, Cr equiv. -8.29 in which equiv chromium equivalent and equiv. = 30(%C+N) + 0.5(%Mn) + (%Ni) - 1.3(%Cr) - (%Mo)+11.8 Ni equiv. = (%Ni) + 30(%C+N) + 0.5(%Mn); Cr equiv. = (%Cr) + (%Mo) + 1.5(%Si) + 0.5(%Nb). Method does not require strict control of the cooling water, or complicated plating procedures for the Cu mould, which has a long life.

摘要： PROBLEM TO BE SOLVED: To provide a floor using a stainless steel plate floor material, imparting no fatigue feeling, by surely performing a seal without causing separation and falling-off, even in a small quantity of sealant used for a joint part.
SOLUTION: This laminated floor material is composed of a stainless steel plate 3 and an elastic material plate 4 stuck to the reverse of the steel plate 3. The stainless steel plate floor material 1 is obliquely cut, so that an elastic material plate end surface 5 becomes smaller in the area of the other surface than the surface contacting with the stainless steel plate, and is stuck at a prescribed interval on a floor surface 10 by using an adhesive, and then, the sealant 2 is filled in a substantially trapezoidal cross-sectional space formed between the floor materials.

摘要： PROBLEM TO BE SOLVED: To provide a pool floor capable of lifting and lowering by winding or unwinding of a winding device, being used as a sport floor during non-use time, simply attaching to an existing pool, disturbing no pool floor by reducing the set space of a pool side during use of the pool and the sport floor and eliminating risk due to the contact of the winding device during driving. SOLUTION: Supports 1 are set on a pool side at constant intervals, and a winding drum 3 driven by a motor 4 is attached to a frame 2 fixed on the upper end of each support 1. A pool floor 9 is connected to a wire 7 pulled from the winding drum 3, and lifted and lowered by winding or unwinding of the winding drum 3. The wire 7 is coated through a pipe 14, and fouling is prevented by grease or the like adhered to the wire 7.

摘要： PURPOSE:To provide titled slag which decreases hollow defects and defects occuring in slag inclusion which are liable to occur with an ingot of an initial period of continuous casting by adding and compounding a specific ratio of MnO to and with slag of which the basicity is controlled to a prescribed range. CONSTITUTION:New artificial slag for initial period of continuous casting consisting of adding and compounding 1-6wt% MnO to and with slag of which the basicity (CaO/SiO2) is controlled to a 0.8-1.2 range. This artificial slag is initially charged at the start of continuous casting, and after 5-6min of use thereof, it is switched to artificial slag contg. no MnO, and the casting may be continued. As a result, the quality of the ingot in the initial period of the casting is improved up to a level approximately equal to the quality of the ingot in the stable period by the articial slag contg. no MnO. Hence, it is possible to eliminate completely the crop scraps for said part produced heretofore unavoidably owin to the physical factors in the initial period of casting.

摘要： PURPOSE:To prevent generation of uneven billet thickness, lamination and rippled surface with a casting mold formed of stationary walls and moving mold surfaces by coating lubricants having high and low viscosities to the prescribed parts on the moving mold surfaces. CONSTITUTION:Stationary walls 2a, 2b are disposed to face each other on moving mold surfaces 1a, 1b and the space corresponding to the width of a thin billet 3 is provided therebetween. Said surfaces 1a, 1b are formed of a pair of casting rolls or casting belts and are disposed to face each other apart at the space corresponding to the thickness of the billet 3. A lubricant having a high viscosity is coated to the parts of the surfaces 1a, 1b facing the walls 2a, 2b and a lubricant having a low viscosity on the parts facing the molten metal between the walls 2a and 2b. The molten metal is supplied into the continuous casting mold formed of said surfaces 1a, 1b and the walls 2a, 2b to obtain billet 3. The cooling rate in the width direction of the billet 3 is thus made uniform and the generation of uneven billet thickness, lamination and rippled surface is prevented.
