摘要： PROBLEM TO BE SOLVED: To improve the rigidity of the overall structure by a reduction in local bending deformation and to improve the safety of the structure by a limit of breakage to a face plate by specifying the interval between an intersection of wavelike ridges at a thickness center line of a core material and a thickness center line of a face plate. SOLUTION: In the corrugated core material sandwich panel comprising two face plates 1 extrusion molded and disposed in parallel and a corrugated core material 2 disposed between the plates 1 and integrally connected to the plates 1, the interval between an intersection of wave-like ridges at a thickness center line of the material 2 and a thickness center line of the plate 1 is set to 1/2 or less of the thickness of the face plate. From a standpoint of dynamics, its offset amount is desirably 0 (mm). It is difficult to always manufacture such a corrugated core material sandwich panel having 0 (mm) of the offset amount due to processability such as of extrusion molding or the like. Incidentally, if the offset amount exceeds 1/2, the rigidity is not improved similarly to a conventional panel.

摘要： PURPOSE:To provide the composite cylinder for injection molding machines for which ordinary steel products not requiring a heat treatment are usable as a cylinder body and which has a long life in use at and under a high temp. and high pressure. CONSTITUTION:The composite cylinder for injection molding machines which is constituted by forming a lining layer 2 consisting of a sintered material of powder for lining by hot isostatic pressurization on the inside surface of the cylinder body 1 consisting of the steel products is formed with the lining layer 2 in such a manner that the stress acting on the inside surface of an injection stroke part 3 of the above-mentioned lining layer 2 is below fatigue strength. The thick part of the lining layer 2 is not required to be formed over the entire area of the lining layer 2 and may be formed only in the injection stroke part 3 of the lining layer 2 where a high pressure acts and near this part.

摘要： PURPOSE:To accurately discriminate whether a fault at a joining boundary exists on the upper surface side or lower surface side of an inserted material at real time by discriminating the jointed state of the joined boundary from peak values of both (+) and (-) polarity parts of reflected echo waves. CONSTITUTION:When reflected echo waves of ultrasonic waves 7 are used, reflected waves from the boundary between a cemented carbide 4 and upper surface of an inserted material 6 and those from the boundary between the lower surface of the material 6 and steel 5 are superimposed upon another, since joined surfaces where no fault occurs exist between material 6 and cemented carbide 4 and steel 5. When ultrasonic waves 8 are used, the reflected waves basically become the same as the reflected waves obtained when only the cemented carbide 4 exists. In the case of ultrasonic waves 10, the reflected waves are composed of those from the boundary at the upper surface of the material 6 and those from a fault 1, since the fault 11 exists between the material 6 and steel 5. Therefore, when peak values of both (+) and (-) polarity parts are detected from the waveform pattern of reflected waves, whether a fault exists on the upper surface or lower surface of the inserted material can be discriminated at real time.

摘要： PURPOSE:To improve heat resistant impact by a method wherein a compression initial stress is exerted on a covering member made of ceramics, a heat insulating layer is formed between the covering member and a reinforcing member made of a metal disposed in the covering member, and a compression stress is generated even in a steady state. CONSTITUTION:When a part is applied for a vane part 2 and a stator blade 1 for a gas turbine formed with mounting parts 3 and 3 formed at both ends thereof, the blade part 2 is formed such that a metallic liner 6 serving as a reinforcing member is inserted and situated in a ceramic shell 4 serving as a covering member with a heat insulating layer 5 therebetween. In this case, the shell 4 is compressed and nipped by means of a mounting part 3 so that a compression initial stress is generated under a room temperature state at the shell 4. The heat insulating layer 5 is formed between the shell 4 and the liner 6 so that a temperature difference is produced under a steady using state between the shell 4 and the metallic liner 6. This constitution enables the com pression stress of the shell 4 to be held in a given range by means of a tempera ture difference, a difference in the coefficient of thermal expansion, and a sec tional area ratio between the shell 4 and the liner 6.

摘要： PURPOSE:To obtain the sufficient joint strength of the joined body formed by non- melting high-temp. joining of 1st and 2nd members which are large in coefft. of thermal expansion by specifying the shape at the edge part of the joint boundary face of the 1st member. CONSTITUTION:The edge at the joint boundary face of the member 1 of the joined body formed by joining the 1st member 1 having the small coefft. of thermal expansion and the 2nd member 2 having the large coefft. of thermal expansion without melting the same is formed to the curved shape having the radius of a prescribed value or above when viewed in the joint boundary face direction. For example, the circumferential edge at the joint boundary face of the member 1 of the joined body formed by joining the members 1, 2 via an insert material 3 is worked to an arc shape of a radius R. The tensile stress based on the difference of coeffts. of thermal expansion between the member 1 and the member 2 is thereby effectively decreased and the generation of the exfoliation and crack at the boundary face end is prevented. The shape of the members may be any of a columnar or prismatic shape and the combination thereof may be any of the circular columns with each other, the prisms with each other, and the circular column with the prism, etc.

摘要： PURPOSE:To prevent the buckling phenomenon caused on a can wall bead part effectively by reducing the load in the axial direction with friction force due to the contact of the inner face of a holding metal die and a storage bead pipe in case of performing a forming in the axial direction for the upper part opening which projects on the holding die of an Al bead can. CONSTITUTION:A can 1 is held by a holding metal die 2 in case of performing a necking on an Al bead can 1 by a necking die 4 for instance. In this case, the straight cylindrical clamp sleeve 5 having the inner diameter conforming to the outer diameter of the bead projecting part 1b of the bead part 1a of the can 1 is stood on the bottom part 2a of the metal die 2 integrally. A sealed pressurized chamber 6 is formed between the sleeve 5 and die 2 to feed pressure air inside the chamber 6. The load in the axial direction in necking is borne with the total surface area of the sleeve 5 by the contact pressure and friction force which is caused between the sleeve 5 and bead part 1b accordingly. Consequently the load to be charged by the projection part 1b is remarkably reduced and the generation of bucklings on the bead part 1a due to the axial direction load of the can 1 can be prevented.
