  • Patent number: 10153098
    Abstract: It is a method for producing an electrode material containing Cu, Cr and a heat-resistant element. A heat-resistant element powder and a Cr powder are mixed together such that the heat-resistant element is less than the Cr by weight. A resulting mixed powder is baked. A resulting sintered body containing a solid solution of the heat-resistant element and the Cr is pulverized, and a resulting solid solution powder is classified, to have a particle size of 200 ?m or less. 10-60 parts by weight of the classified solid solution powder and 90-40 parts by weight of a Cu powder are mixed together, followed by sintering to obtain the electrode material. If a low melting metal powder having a median size of 5-40 ?m is mixed with a mixed powder of the solid solution powder and the Cu powder, the deposition resistance property is further improved.

  • Patent number: 10153099
    Abstract: The invention disclosed is a knife blade switch 2 having copper jaws 10 and a copper blade 4 with a steel end-plate 6 fastened to the free end of the blade, the steel end-plate having a higher resistivity than the resistivity of the copper blade and copper jaws. As the copper blade is withdrawn from the copper jaws, the steel end-plate of the blade remains in contact with a higher resistivity steel jaw-spring mounted on and electrically connected to the copper jaws. The connection of the steel end-plate 6 of the blade with the steel jaw-spring 12 imposes a greater resistance path for the current flowing through the switch than through the copper blade 4 and copper jaws 10, so that an arc formed at the plate and jaw-spring has a diminished current, over what would otherwise occur with a copper blade and jaws, when the contact separation occurs.
