摘要： PROBLEM TO BE SOLVED: To surely incorporate a piston into a cylinder bore with a simple structure and to reduce incorporating work cycle time. SOLUTION: A connecting rod 32 is inserted into a cylinder bore 23 of a cylinder block 21 arranged in an upright position. Then, a piston 30 having an offset ϕ against the cylinder bore 23 is arranged at an opening part 24 of the cylinder bore 23 and a lower edge outer periphery of the piston 30 is partially dropped into the cylinder bore 23. A posture of the piston 30 currently inclining against the cylinder bore 23 is changed to be coaxial with the cylinder bore 23 and the whole periphery of the lower edge of the piston 30 is dropped into the cylinder bore 23. Then the whole body of the piston 30 is pushed in the cylinder bore 23 while reducing diameters of piston rings 33.

摘要： PROBLEM TO BE SOLVED: To improve the strength of a cutting edge and prevent the impairing of the cutting quality by applying the nitriding treatment to a cutting edge of a punch plate. SOLUTION: The nitriding treatment is executed on a cutting edge 4 of a punch plate 2 for a flat die 3 manufactured by demountably mounting an acceptor 1 and a punch plate 2 by magnetic action. The nitriding and the carbonizing are simultaneously executed on a surface of the knife blade 2, and a nitriding treatment layer of a nitride layer and a carbide layer is formed on the surface of the knife blade 2. Whereby the surface of the knife blade 2, that is, the cutting edge 4 is hardened. When this nitriding treatment layer is too thin, the rigidity of the knife blade 2 is insufficient, and a matter to be cut such as a material harder than a label such as a resin plate and the like and a thick material can not be cut in a good condition (cutting quality is immediately impaired). Accordingly in a case of the knife blade 2 for flat die 3, a thickness of the nitriding treatment layer is determined to be 6 μm or more, whereby the frictional characteristic and the cutting quality can be also improved.

摘要： PROBLEM TO BE SOLVED: To fix a stud to a sheet by a flange and an expanded part with sufficient strength by inserting a hollow cylindrical part in a through hole in the sheet to closely attach the flange to a sheet surface, pressing a spherical body larger in diameter than the inside diameter of the hollow cylindrical part to expand a part projecting from the sheet. SOLUTION: The length L of a hollow cylindrical part 4 of a stud 1 projecting from a sheet 6 is set to be larger than the radius R of a spherical body 5 to be pressed into a shaft hole 3. Since the spherical body 5 is held in the shaft hole 3 of the hollow cylindrical part 4 expanded by the press-fitting of the spherical body 5, the specified tightening strength is maintained without contracting the hollow cylindrical part 4. Since the spherical body 5 seals an opening end of the shaft hole 3 and left behind, water is prevented from entering the shaft hole 3, and the rust-preventive performance of a joined part of the sheet 6 with the stud 1 is improved. When the length L of the hollow cylindrical part 4 is set to be smaller than the radius R of the spherical body 5, the spherical body 5 expands the hollow cylindrical part 4 to be semi-spherical, and is dropped to enable the recycling.

摘要： PROBLEM TO BE SOLVED: To judge the quality of a welded state from the bead width at the time of butt welding metal plates and to judge the existence of the deviation of the weld position from the target position in the butt welding of a pair of works having different plate thickness. SOLUTION: The cross section profile of the weld zone of butt welded works 1, 2 is measured by a light-section method or the like, the imaginary and effective bead width rather smaller than the actual width of the bead 3 is calculated by a numerical operation from the coordinate data on the cross section shape of the upper and bottom surfaces of works 1, 2 and the surface of the bead 3. Utilizing that this effective bead width is positively correlated with the actual bead width, the quality of the welded state of the penetration or the like of the bead 3 is judged based on the effective bead width. Also, in the case of butt welding works 1, 2 having different plate thickness, the inclination of the cross section profile of the bead 3 is measured, the existence of the deviation of the weld position is judged by comparing the measured inclination value with the pre-recorded reference value.
