摘要： A conversion adapter to be used for connecting opposed optical connector ferrules having different diameters is formed of an amorphous alloy possessing at least a glass transition region, preferably a glass transition region of not less than 30 K in temperature width. Particularly, the amorphous alloy of M1—M2 system or M1—M2—La system (M1: Zr and/or Hf, M2: Ni, Cu, Fe, Co, Mn, Nb, Ti, V, Cr, Zn, Al, and/or Ga, La: rare earth element) possesses a wide range of &Dgr;Tx and thus can be advantageously used as a material for the conversion adapter. Such a conversion adapter can be manufactured with high mass-productivity by a mold casting method or molding method.

摘要： A method for the production of a cast article having a small hole comprises the steps of setting a linear core member in a cavity of a metal mold, injecting a molten metal into the cavity, and drawing out the core member from the resultant-cast product to form a small hole. A linear core member having a surface film formed by surface coating or by subjecting to a surface treatment is used so that the surface film is partly or as a whole peeled off the linear core member upon drawing it from the cast product, thereby enabling the core member to be drawn from the inside of the cast product. Alternatively, the linear core member is so constructed as to elastically deform in the drawing direction upon drawing it from the cast product to have a diameter smaller than the original diameter.

摘要： A high strength, rapidly solidified alloy consisting of aluminum and, added thereto, additive elements. The mean crystal grain size of the aluminum is 40 to 1000 nm, the mean size of particles of a stable phase or a metastable phase of various intermetallic compounds formed from the aluminum and the additive element and/or various intermetallic compounds formed from the additive elements themselves is 10 to 800 nm, and the intermetallic compound particles are distributed in a volume fraction of 20 to 50% in a matrix consisting of aluminum. The rapidly solidified alloy has an improved strength at room temperature and a high toughness and can maintain the properties inherent in a material produced by the rapid solidification process even when it undergoes a thermal influence during working.
