  • ELECTROPHOTOGRAPHIC CLEAR TONER AND IMAGE FORMING METHOD
    Publication number: 20120156604
    Abstract: Provide is a clear toner having a wide fixing temperature latitude so as to improve the degree of glossiness in a wide range of image density areas, from a white portion to a high image density portion, while ensuring sufficient fixing performance and color mixing in color portions. The clear toner has a storage elastic modulus G? (130) of 1.0×104 Pa or more at 130° C. and a melt viscosity ? (130) of 1.0×104 Pa·s or less at 130° C.

  • Lithium manganese complex oxide anode material for lithium secondary batteries and a lithium secondary battery using the same
    Patent number: 6465130
    Abstract: The anode material to be used for non-aqueous electrolyte secondary batteries according to the present invention is composed of a Li-Mn type complex oxide having a spinel structure, either or both of the occupancy rate (gc) value of cations in an unit lattice of the material to be determined based on the composition, the lattice constant and the density or/and the ocupancy rate (ga) value of anions in an unit lattice of the material to be determined based on the composition, the lattice constant and the density is/are adjusted to a value of 0.985 or less. The actions of the complex are partially substituted with aluminum or magnesium.
