  • Power storage device and method of measuring voltage of storage battery
    Publication number: 20010011881
    Abstract: A power storage device has a plurality of series-connected storage battery units, battery circuits associated with the storage battery units to control or monitor the storage battery units, respectively; a main circuit of a potential level different from that of the battery circuits; and a potential level changing circuits connecting the battery circuit to the main circuit. The power storage unit is small in construction and operates at a low power consumption in a high control accuracy.

  • Method and apparatus of discriminating coal species
    Patent number: 5873982
    Abstract: In a method and apparatus for discriminating a coal species, discriminating values of coal species/properties are prepared corresponding to coal ranks, a coal to be discriminated is irradiated with near-infrared rays having different wavelengths, and light of near-infrared rays reflected from the coal is received; Aborbances of the coal are acquired, and the coal species/property discriminating value of the coal is discriminated on the basis of the absorbances and a prescribed calibration curve.
