摘要： An improved billet and process for producing a tubular body by forced plastic deformation is disclosed. The billet includes a metallic tubular sheath, a metallic center core and a salt intermediate core. The radial thickness of the metallic tubular sheath is equal to or less than 0.11 times the outer diameter of the metallic tubular sheath. The metallic center core is positioned within the tubular sheath and is surrounded by the salt intermediate core which fills the cylindrical space between the tubular sheath and the center core. In the process of the present invention, the foregoing billet is subjected to forced compulsory deformation to reduce the diameter of the billet. Thereafter, the intermediate core is removed through solution and the center core is drawn out of the sheath in order to obtain the tubular body.

摘要： In production of a composite material such as an elongated Ti-base composite material advantageously used for eyeglass frames, a crude composite material formed by application of at least one surface layer of a component material to a base block by means of spraying processing is subsequently subjected to pressure application preferably with heat. A multi-layer construction can be easily obtained even starting from a base block of an intricate surface configuration thanks to employment of the spraying process, and the final pressure application assures strong diffusion bonding between the core block and the surface layers. The base block may be given in the form of a mold to be ultimately removed from the product.

摘要： Through employment of a core-and-sheath construction having a number of axially elongated indentations along the border for the billet with the core of an easily soluble material, extrusion such as hydrostatic extrusion can advantageously be utilized for production of heat pipes with enhanced precision and operational efficiency in process. Indentations, which work as a wick in the heat pipe, may be provided by forming axially elongated grooves either in the inner peripheral surface of the sheath or in the outer peripheral surface of the core.

摘要： A flat type display tube has an exhaust tube extending outward in a plane of the surface of the substrate and a plurality of current supply lead-in strips. The exhaust tube and lead-in strips extend in the same direction from a body of the display tube. The lead-in strip is bent partway in a position short of the exhaust tube and in a direction substantially vertical to the plane of the surface of the substrate.
