摘要： PROBLEM TO BE SOLVED: To provide a method of manufacturing a thin hole tube having good inside surface finishing accuracy by controlling conditions for selection of the material quality of a core material, the composition of an electroplating bath, etc., so as to generate the internal stress of compression in an electroforming layer, thereby easily removing the core material without the addition of means for dissolving, melting, etc. SOLUTION: Both ends of the core material 5 are mounted at a fixture 1 and shielding tapes are deposed near the mounting parts. A fixture body is immersed into a bath liquid 10 of an electrolytic cell 9. The bath liquid is internally provided with a plurality of nickel anode electrodes 11. The core material 5 is rotated by a motor 7 and the electroforming layer is formed on the surface of the core material 5. Where the layer attains a prescribed thickness, the fixture 1 is pulled up from the electrolytic cell 9. The integrated body of the core material 5 and the electroforming layer 12 is removed and the shielding tapes are removed. The electroforming layer 12 is detained to a fixture for pulling the core material and the core material 5 is pulled, by which the pore tube by the nickel electroforming layer is completed.

摘要： PROBLEM TO BE SOLVED: To make an underlying film unnecessary and attain reduction in a manufacturing process for a hollow structure, by causing the hollow structure to have a shape of a straight line, a curved line, or a combination thereof in the direction of length. SOLUTION: A chromium 1 is used as a core material having a uniform diameter, and the chromium is impregnated with a plating solution, thus forming a soft magnetic thin film of permalloy 2 on the chromium core material 1 by electroplating. The core material is cut to a required length by a wire saw 3 to provide a cylinder 4 made of the chromium 1 and the permalloy 2. In addition, this cylinder 4 is impregnated with a chromium etching solution, and the core material is completely etched to form a hollow cylinder 5 made of the soft magnetic thin film of permalloy. Etching is further continued to etch a substantially right edge 6, which falls on a cross section formed by cutting the hollow cylinder 5. Thus, a hollow structure formed by changing the shape of the edge of the hollow cylinder 5 to an arc-shaped edge 8, that is, a micro- pipe 7 is manufactured.

摘要： PROBLEM TO BE SOLVED: To avoid small unevenness from being caused on a guide wave face by using a waveguide matrix made of copper or a copper alloy. SOLUTION: A brass being a copper alloy is used for a blank material 11. That is, in the case of applying precise machine processing to a blank material 11 into a prescribed shape and size, e.g. a waveguide matrix (convexed die) 12 whose cross section is circular, the waveguide matrix (convexed die) 12 is put into a 1st electroforming cell such as an Au electroforming cell 20 to form an Au layer 13 on the surface. Then the brass blank material 11 with the Au layer 13 adhered thereto is put into other metal electroforming cell such as a Ni electroforming cell 21, in which a Ni layer 14 is similarly electroformed. Then the raw material for which the electroforming process is finished is taken out of the Ni electroforming cell 21 and put into the matrix a mother melting and removing chemicals cell 22, in which the waveguide matrix 12 in the center is molten and removed. Thus, the surface precision equal to that obtained by machining is obtained for the inner surface of a waveguide 10.
