    摘要: A hyper-eutectic aluminum-silicon powder containing extremely fine primary crystal silicon, is prepared by atomizing. First, a molten metal of a hyper-eutectic aluminum-silicon alloy containing phosphorus is prepared. This molten metal or melt is atomized with air or an inert gas and quench-solidified. Aluminum-silicon alloy powder containing primary crystal silicon of not more than 10 .mu.m in crystal grain size is obtained. This aluminum-silicon alloy powder contains at least 12 percent by weight and not more than 50 percent by weight of silicon and at least 0.0005 percent by weight and not more than 0.1 percent by weight of phosphorus. When this hyper-eutectic aluminum-silicon alloy powder is employed, it is possible to prepare a consolidate of powder which has improved mechanical properties, and provides a high yield.

    摘要: To prepare an aluminum matrix particle composite alloy, a molten metal, mainly composed of aluminum, containing ceramic particles is disintegrated by atomization, to prepare atomized powder. The atomized powder is mechanically ground/reflocculated with a ball mill or the like, to prepare mechanically ground/reflocculated powder containing ceramic particles of not more than 8 .mu.m in maximum diameter and not more than 3 .mu.m in mean particle diameter. The mechanically ground/reflocculated powder is then warm-formed/solidified. Alternatively, an aluminum alloy molten metal containing dispersed particles is disintegrated by atomization, and thereafter the powder containing the dispersed particles of not more than 20 .mu.m in mean particle diameter is warm-formed/solidified by powder forging. Thus, it is possible to obtain an aluminum matrix particle composite alloy in which extra-fine ceramic particles are homogeneously distributed without segregation.

    摘要: The invention provides aluminum sintered alloys with high dimensional accuracy and high density which are superior in mechanical and physical characteristics as well as wear resistance, and a method of producing such alloys not by plastic working but by atmospheric sintering with high economy. Rapidly solidified aluminum alloy powder resulting from solidifying aluminum alloy molten metal containing 0.4 to 4.0% by weight of Mg at a solidification rate of 10.sup.2 .degree. C./sec or more is press molded in the cold, after annealing in the temperature range of 250 to 450.degree. C. if necessary, and then the molded product is sintered by generating nitrogen compounds on the powder surface at atmospheric pressure with a nitrogen partial pressure of 0.8 atm or more and a steam partial pressure of 0.01 atm or less in which a reducing gas component has been added as a nitrogen-combining acceleration gas component by 0.01 atm or more. Thus, a nitrogen-combined aluminum sintered alloy containing 0.4 to 4.0% by weight and 0.2 to 4.0% by weight of nitrogen is obtained.

    摘要: According to the present invention, as a result of using a depressed or trench-assisted light-receiving waveguide in which the core is surrounded by a layer having a refractive index lower than that of a cladding as light-receiving means for receiving light outputted from a multi-core optical fiber, the layer of a low refractive index can inhibit the propagation of noise, etc. from the cladding to the core. Consequently, even in cases where the inter-core crosstalk is small, it is possible to accurately measure the inter-core crosstalk since components different from crosstalk-derived components in optical power are reduced.
