A method for producing a compact of rare earth alloy powder of the present invention includes: a powder-filling step of filling rare earth allow powder in a cavity formed by inserting a lower punch into a through hall of a die of a powder compacting machine; and a compression step of pressing the rare earth alloy powder while applying a magnetic field, the steps being repeated a plurality of times. When the (n+1)th (n is an integer equal to or more than 1) stage compression step is to be carried out, the top surface of a compact produced in the n-th stage compression step is placed at a position above the bottom surface of a magnetic portion of a die.

摘要:
A bolt fastening method enabling the same effect as when reducing the coefficient of friction of a thread surface without changing the coefficient of friction of the thread surface so as to realize an increase in a bolt axial force generated when fastening the bolt and a bolt fastening device realizing the bolt fastening method are provided.The bolt fastening method of the present invention is a bolt fastening method for when using a bolt having a bolt head and a bolt shank provided with an external thread to fasten fastened members, characterized by intentionally biasing surface pressures of a thread surface and a bolt bearing surface generated when fastening the bolt by imparting a lateral load parallel to the bolt bearing surface to the bolt head and, in that state, imparting a rotational torque rotating the external thread to the bolt head so as to fasten the bolt.

摘要:
A liquid mixture containing a liquid polymeric material and a granular filler is injected into a mold (11) for centrifugal molding and subjected to centrifugal molding, thereby preparing a cylindrical body including a homogeneous dispersion layer (2) having the filler homogeneously dispersed in the polymeric material and a high-density packed bed (1), formed on the outer peripheral surface side or on the inner peripheral surface side of the homogeneous dispersion layer (2), containing the aforementioned polymeric material more densely filled with the aforementioned filler. The high-density packed bed (1) is removed for exposing the surface of the homogeneous dispersion layer (2). According to this structure, the yield of the elastic cylindrical body can be improved.
摘要:
A shielded flat cable includes a plurality of juxtaposed insulating layer-coated signal wires, a drain wire disposed on one side of the group of the signal wires, a shielding layer covering an outer periphery of the group of signal wires and drain wire, and an insulating sheath covering an outer periphery of the shielding layer. A conductor of at least the outermost signal wire of the plurality of signal wires which is remote from the drain wire is made of a copper alloy.
摘要:
A shielding tape, wherein a shielding layer is laminated on one side with an adhesive agent layer for a core for adhering an insulation shielding material of a core wire, and laminated on the other side with a reinforcing seat layer, and laminated with an adhesive agent layer for a sheath for adhering the sheath on the reinforcing seat layer, is characterized in that adhesive strength of the adhesive agent layer for the core to the insulation shielding material is smaller than adhesive strength between the respective layers. Preferably, the shielding materials and the sheath are composed of a non-halogen material, the adhesive agent for core and the adhesive agent for sheath are composed of the non-halogen material, and adhesive force of the adhesive agent for core to the insulating material is smaller than adhesive force of the adhesive agent for sheath to the sheath.
