    摘要： The features of the present invention are 1) to apply metallization on the bonding surface of a piezoelectric ceramic with a metal likely to react with the piezoelectric ceramic material, 2) when the piezoelectric ceramic material is soldered on the bonding surface, to apply metallization with a metal likely to react with the solder material, 3) to provide between the metallizing layers formed in 1) and 2) a metallizing layer including metal which prevents reaction between the metals and their diffusion, 4) to use a mounting member for the piezoelectric ceramic which has substantially the same thermal expansion coefficient as the piezoelectric ceramic in non-polarization condition and 5) to solder in the non-polarization condition and thereafter to polarize. As the result, a bonded type piezoelectric apparatus with a high reliability or with a broad application temperature range near from the absolute zero temperature to the Curie point of the piezoelectric element, and a method of manufacturing the same are provided.

    摘要： A rotary tool (200) having on the end surface of a large-diameter portion (210) facing a small-diameter portion (220) grooves (213) formed in arc-like shapes, and performing friction stir weld by inserting the end surface of the large-diameter portion (210) and the small-diameter portion to members and rotating the tool (200). By the rotation, the metal of the members moves along the grooves (213) to the center axis direction of the rotary tool (200). The arc-shaped grooves (213)are formed to curve toward the direction of rotation. Since the metal material of the members is moved toward the center, a good weld is realized even when only one of the members to be welded has a projection, or when a large gap is formed therebetween.

    摘要： In a railway car, extruded frame members of an aluminum base alloy containing Si of 0.4-0.9 wt % and Mg of 0.4-1.2 wt % are welded according to a friction stir welding method. In a structure, an aluminum base alloy plate containing Si of 0.4-0.9 wt % and Mg of 0.4-1.2 wt % is prepared, to one face of the aluminum base alloy plate a rib is formed, and the aluminum base alloy plate is an extruded frame member. Accordingly, a railway car having a low welding distortion and a structure having a low welding distortion can be obtained.

    摘要： Disclosed is a friction stir welding technique which avoids occurrence of a dent, in adjoining region, extending to a level beneath the joined surfaces. At end portions of the frame members to be joined, at the joining region, thickened parts which project toward the rotary body joining tool are provided. Two adjoining thickened parts, of adjacent members to be joined, can form a trapezoid shape. The rotary body joining tool has a small-diameter tip portion and a larger diameter portion. The rotary body joining tool is inserted in the thickened parts. In a state where the rotary body joining tool has been inserted small-diameter tip and first, to a level where the larger diameter portion of the rotary body joining tool overlaps the thickened part but does not extend below the upper surface of the non-thickened surfaces of the members joined, the rotary body is rotated and moved along the joining region. Even when a gap exists between two thickened parts, a desirable joining can be carried out. After the joining, the remaining parts of the thickened parts can be machined so as to form a smooth surface.
