  • Patent number: 7585607
    Abstract: A method of manufacturing a toner including dissolving or dispersing a toner component containing a colorant and a resin in an organic solvent to obtain a liquid solution or dispersion, continuously emulsifying and dispersing the liquid solution or dispersion in an aqueous medium containing a particulate dispersant to obtain emulsified primary particles, controlling cohesion and agglomeration of the emulsified primary particles and removing the organic solvent, such that the ratio (T1/T2) of the arithmetic mean accumulation time (T1) of the emulsified primary particles obtained in the controlling step to the arithmetic mean accumulation time (T2) of the emulsified primary particles obtained in the continuously emulsifying and dispersing step is from 1 to 5.

  • Patent number: 5535750
    Abstract: An ultrasonic signal is transmitted to a heel bone or patella of a person being examined to obtain data of velocity of transmission propagation. The data which is obtained is computerized through calculation to compute a two-dimensional ratio of a compact bone to a bone structure (Au) from a one-dimensional ratio of a compact bone to a bone structure (Eu). Then, a chart is drawn to suffice an Au for which a fractal geometry is utilized to compare the chart with an image of an Au of a healthy person who is under the same condition in sex and age. The portions different from each other are then sorted by color for evaluating the progress of osteoporosis.
