  • Patent number: 10961607
    Abstract: A hardfacing alloy satisfies the following condition when the hardfacing alloy as a whole is 100 mass % (also simply referred to as “%,” hereinafter), Ni: 10-25%, Si: 1-3%, Fe: 3-18%, the total of one or more elements of Mo, W, and Nb: 6.5-20%, and the balance: Cu and impurities. In particular, it preferably satisfies Fe+2Mo?22.6(%), Mo equivalent/Fe?1.17, and Mo equivalent=Mo+0.522W+1.033Nb. In a hardfacing part composed of the hardfacing alloy, coarse hard particles are formed to ensure the wear resistance, and a soft phase present in the hard particles ensures the machinability. This may be understood as a raw material powder for hardfacing treatment and may also be understood as a hardfacing member in which a hardfacing part is formed on a base material using the raw material powder.

  • Patent number: 10840628
    Abstract: A connector which can improve reliability of electrical connection is provided. Accommodation recesses are formed to a plate-like terminal member, and a coil member accommodated in the accommodation recesses is retained to the terminal member, thereby allowing wire winding portions of the coil member to be deformed within the accommodation recesses when the winding wire portions are sandwiched between bottom faces of the accommodation recesses and a mating terminal. Consequently, the obliquely wound coil member is not likely to experience deformation other than fall over of ring portions, and/or is not likely to be displaced, improving contact between the coil member and both of the terminal member and the mating terminal. As a result, reliability of electrical connection can be improved.
