摘要： PROBLEM TO BE SOLVED: To fill a narrow and deep space with the metal powder without generating unevenness and shortage and excessiveness independently of weather by arranging a holding sleeve at the specified length inside of a metal sleeve, and filling the metal powder between them. SOLUTION: Metal powder 3 is filled in an annular space between a sleeve 1 and a holding sleeve 4, and both ends thereof are sealed by annular plugs 5a, 5b. Appropriate thickness of the holding sleeve depends on the thickness of wires 2a, 2b, quantity of the metal powder to be used at the time of junction and the set packing density of the metal powder 3, but the thickness at 1mm or less is appropriate. When the holding sleeve 4 separated from the wires 2a, 2b is pulled out, the metal powder 3 contacts with the surface of the wires. At this stage, when a detonator is installed in the explosive for explosion, the sleeve 1 is shrunken inward by the explosion pressure of the explosive, and the metal powder 3 is pushed to the surface of the wires by the pressure, and the sleeve 1 and the wires 2a, 3a are joined to each other.

摘要： PROBLEM TO BE SOLVED: To avoid the galloping by a method, wherein multiconductor wire spacers in which wire holding parts and spacer frames support each other with belleville springs between them are attached with suitable spacer distances. SOLUTION: A clamp 3 which holds a wire 2 penetrates a chamber 5, which is unified with a spacer frame 1. A pair of belleville springs 4 are piled in a same direction, and two such pairs are made to face each other with recessed parts on the facing sides to form one set. Several sets of the belleville springs 4 are symmetrically provided on both the sides of the chamber 5. The shaft part of the clamp 3 are inserted through the center holes of the belleville springs 4 to fix the clamp 3. When the wire 2 comes close to the chamber 5, the belleville springs 4 on the side of the chamber 5 near the wire 2 are compressed, and when the wire 2 leaves the chamber 5, the belleville springs 4 on the side far from the wire 2 are compressed. Further, as the holes through which the shaft part of the clamp 3 are inserted are tapered, the horizontal shaking can be also followed. As a result, the part of the vibration energy of the wire vibration is absorbed, and the galloping can be prevented beforehand.

摘要： PROBLEM TO BE SOLVED: To provide a novel method for metallurgically jointing two wires as the stranded wires of aluminum or an alloy thereof, or copper or an alloy thereof for transmission and distribution lines or the like, to a sleeve capped to wires kept in contact and parallel with each other and formed out of the same material as the wires. SOLUTION: This method places two wires 1a and 1b to be jointed in parallel and contact with each other and the part to be jointed is covered by winding a metallic filament 2 of the same material as the wires 1a and 1b, or with a cloth type material (including nonwoven fabric and felt type product) woven by use of the same material as the wires 1a and 1b, over the prescribed length. In addition, a sleeve 3 of the same material as the wires 1a and 1b is capped to the covered surface. Then, a direct or indirect centripetal explosion shock is applied to the wires 1a and 1b, and the metallic filament 2 via the external surface of the sleeve 3. The metallic filament 2 is compressed and heated with the shock and kept in a molten state or at high temperature nearly equal to the molten state. The wires 1a and 1b, the metallic filament 2, a buried fitting and the sleeve 3 are thereby jointed to one another integrally and metallurgically.

摘要： PROBLEM TO BE SOLVED: To prevent the collision of explosive, and to prevent the increase of pressure, and to prevent the generation of damage of a metal to be worked by arranging an explosion inert material for shielding an explosive layer of a cylindrical explosive for working metal at a collision estimated position over the core length of the explosive. SOLUTION: An explosive 1, which is detonated from a position at 0 degree in one side of the explosive 1, collides at an opposite position at 180 degree as long as the explosive is made of the even characteristic material. When an explosion inert material 2 is arranged at a position at 180 degree so as to shield the explosion of the explosive, the explosion is concluded at a boundary between the explosive 1 and the explosion inert material 2, and the explosion pressure is transmitted to the explosion inert material 2, and quickly attenuated in the material 2. Since the explosion pressure is transmitted to the explosion inert material 2 from the opposite side, the pressure becomes double at a central part of the explosion inert material 2 or a rise of the pressure is restricted by the attenuation at the time of passing through the explosion inert material 2. Pressure nearly equal to the pressure in the case of exploding the explosive can be transmitted to a metal to be worked by utilizing the explosive inert material 2 at an appropriate dimension.

摘要： PROBLEM TO BE SOLVED: To join electric wires powder-metallurgically and strongly by explosive by covering the outside of 2 electric wires of which ends are closely connected by a metal tube, and filling metal powder of the same quality as the wire in it and by exploding from the outside of the metal tube centripetally. SOLUTION: The ends of two electric wires 1 consisted of a stranded wire of aluminum and copper are closely connected, and the outside is covered with a metal tube 3 which is made of the same quality as the wire 1 and slightly larger in circumference. Then, metal powder 2 of the same quality as the wire 1 of about 1μm-1mm is filled in a space between the metal tube 3 and outside of the wire 1 and between individual stranded wires of the wire 1. A protective layer 5 such as a plastic film is set outside of the metal tube 3 and explosive 4 with explosion speed of about 4000-1900m/sec is placed outside through a case 6. Then, the explosive 4 is fired through a detonator and a fuse and a centripetal impact pressure is loaded from the outside of the metal tube 3. This action presses and heats metal powder 2 and joins the electric wire 1, metal powder 2, and the metal tube 3 integrally and metallurgically.

摘要： PROBLEM TO BE SOLVED: To provide a density of a specific value or above and to improve durability by overlapping ceramic powder and metal powder having melting points of specific values or above, and connecting, molding and sintering them at a high temperature and a high pressure of specific values or above. SOLUTION: Ceramic powder and metal powder having melting points exceeding 2500 deg.C and 2000 deg.C respectively are molded and sintered at the density of 96% or above of the theoretical density under the same conditions as the sintering conditions of diamond, a high temperature of 2000 deg.C or above and a high pressure of 100 MPa or above. A ceramic having a high melting point, a high electron emission capability and low heat conductivity, e.g. LaB6, HfC or HfN, is used at the tip section of a thermoelectron emitting electrode. The remaining section slightly apart from it is made a heat radiation section constituted of a metal having a low thermoelectron emission capability and high heat conductivity, e.g. Ir, Os, W, Ta, Mo or Re. A molded and sintered body provided with the mixed powder of the ceramic powder and metal powder having different thermal expansion coefficients is preferably used, and the shearing stress generated on the faying boundary face at the time of natural cooling is mitigated.
