Title: Magnesium alloy, structural body of magnesium alloy and production thereof
Inventor: ASAI SHIGEMI
IPC: C22F1/06
Filed: 1998-10-13
Abstract: PROBLEM TO BE SOLVED: To suppress the secular change in the shape of a product obtd. by cold press working by composing a magnesium alloy of the one in which the phases are separated in such a manner that the surface layer is composed of the α phases, and the part other than the surface layer is composed of the α+β phases or the β phases. SOLUTION: As to this Mg alloy, the strength, i.e., rigidity of the surface layer can be increased from the inside by the α phases, and, also, by composing the part other than the surface layer its ductility can be made high, and its plastic workability such as cold press workability or the like is improved. Preferably, the structural body of the alloy has a low Li layer having a Li content lower than that in the structural body, and the low Li layer is composed of the α phases. Thus, strength, i.e., rigidity by the low Li layer can be imparted to the structural body. Moreover, by increasing the degree of freedom in the shape by the excellent plastic workability, its cost can be reduced. Furthermore, the more secure formation of a corrosion resistant film by surface treatment is made possible, and it can be provided with excellent corrosion resistance.

Title: Wiring member and wiring structure
Inventor: OGAWA SHINJI
IPC: B60R16/02
Filed: 1998-10-29
Abstract: PROBLEM TO BE SOLVED: To facilitate a treatment and a positioning. SOLUTION: A wiring member 40 constituting a wiring circuit comprises a plurality of conductors 41 and a lapping material 42 (connecting means). The conductors 41 comprises a wire having a flexure rigidity capable of maintaining a shape itself and are bent to a shape along a predetermined wiring route passing through electric parts such as terminal fittings 24, 26, switches 30, 31, a valve 50 and a connector part 16. The lapping material 42 forms a sheet covering a portion other than the connection portion with the electric parts and is integrally formed such that all conductors 41 maintain a predetermined wiring route. Thereby, it is not necessary that the respective conductors 41 are independently mounted to a body 11. Since the conductors 41 has a flexure rigidity capable of maintaining a shape themselves, all conductors 41 can be positioned if the lapping material 42 and one part of the conductors 41 are engaged with the body 11.
