  • Patent number: 8229309
    Abstract: An image forming device includes an image holding member and a charging unit. In a case in which an AC current, while being increased, is supplied to the charging unit in a state in which a DC voltage value and an AC voltage value applied to the charging unit are maintained, or a case in which a DC voltage, while being increased, is supplied to the charging unit in a state in which the AC voltage value applied to the charging unit is maintained, a current detection unit detects DC current values. An inflection point derivation unit derives an inflection point of a correlation line representing an correlation between the detected DC current values and the supply amounts. An execution unit executes pre-specified processing when a characteristic value of the derived inflection point reaches a pre-specified value.

  • Publication number: 20110243086
    Abstract: One region of a plurality of regions into which channels are divided over the radio link as a main region is designated for each of groups into which the cells of the plurality of base stations are divided. When a mobile terminal receives a signal from a second base station other than a first base station to which the own mobile terminal is connected, the mobile terminal notifies the first base station of adjacent status information that represents a group to which a cell of the second base station belongs. The first base station allocates a channel that belongs to a region other than the main region of the group represented by the adjacent status information that the mobile terminal notifies to the first base station.
