  • Carbon material, method for producing carbon material, and non-aqueous secondary battery using carbon material
    Patent number: 11936044
    Abstract: A carbon material for a non-aqueous secondary battery containing a graphite capable of occluding and releasing lithium ions, and having a cumulative pore volume at pore diameters in a range of 0.01 ?m to 1 ?m of 0.08 mL/g or more, a roundness, as determined by flow-type particle image analysis, of 0.88 or greater, and a pore diameter to particle diameter ratio (PD/d50 (%)) of 1.8 or less, the ratio being given by equation (1A): PD/d50 (%)=mode pore diameter (PD) in a pore diameter range of 0.01 ?m to 1 ?m in a pore distribution determined by mercury intrusion/volume-based average particle diameter (d50)×100 is provided.

  • Solder preform and a process for its manufacture
    Patent number: 10081852
    Abstract: A mixed mother alloy is prepared from a solder mixture comprising a pyrolyzable flux and high melting point metal particles, the mixed mother alloy is charged into a large amount of molten solder and stirred, and a billet is prepared. The billet can then be extruded, rolled, and punched to form a pellet or a washer, for example.

  • Material for bearing parts
    Patent number: 6652672
    Abstract: In a material for bearing parts constructed from a steel hardened by a heat treatment, its surface layer is adjusted, before a shot peening treatment, for a mean particle size of carbide to less than 1 &mgr;m, an area percentage of carbide to 10-15%, an amount of residual austenite to 7-14% and a hardness thereof to HRC=61-65; and subsequently, the shot peening treatment is conducted. Thus is produced a material for bearing parts which can satisfy the life requirements for bearings without an excessive increase in a shot time during the shot peening treatment.
