摘要:
A method of fabricating composite metal wires such as aluminium clad steel wires is disclosed which comprises providing a core of hard metal with a cladding of soft metal by extrusion. In fabricating a composite metal wire by extrusion, a core is generally aligned, polished, cleaned or otherwise pretreated before entering an extruder so that a high and variable tension is imparted to the core. By avoiding such tension variation and maintaining the core under a constant low tension and by electrically heating the core before the core enters the extruder, a composite metal wire of improved quality is fabricated in a stable manner.

A memory management device enables to effectively use a memory which permits its stored data to be erase only in blocks. A facsimile apparatus is arranged to temporarily store sending information and received information in the memory and them to send or received the information. The facsimile apparatus includes a flash memory whose data is allowed to be erased only in blocks and a storage unit for storing the sending or the received information in its own blocks if the sending or the received information is stored in the flash memory.

A flat cable conductor has: a conductor made of copper or a copper alloy; a first plating film made of tin and/or a tin-copper alloy, the first plating film being formed around the conductor; and a second plating film made of an alloy of tin and a third element selected from Au, Ag, Ni, Ge, Zn and Bi, the second plating film being formed around the first plating film. The third element has a concentration of 0.01 or more and 80 or less wt % at an outer surface of the second plating film.

An interconnection assembly has phase parts for U phase, V phase and W phase. The phase parts each are of a plurality of interconnection assembly parts that are connected in the form of a ring and include a conductor section to which a motor coil wire is connected, the conductor section being formed by stripping fluororesin insulation at a predetermined position, and the phase parts are partially fixedly bundled.
