  • Patent number: 11967720
    Abstract: An electrode according to an embodiment contains an electrode mixture layer containing an active material and a conductive assistant. In a logarithmic differential pore volume distribution by a mercury intrusion method, the electrode mixture layer satisfies: a ratio P1/P2 within a range of 2 or more and less than 8, and a ratio S1/S2 within a range of 3 or more and less than 10. P1 is a value of a maximum logarithmic differential pore volume in a pore diameter range of 0.1 ?m or more and 1 ?m or less. P2 is a value of a logarithmic differential pore volume of a pore diameter of 0.03 ?m. S1 is an integrated value in a pore diameter range of 0.1 ?m or more and 1 ?m or less. S2 is an integrated value in a pore diameter range of more than 0 ?m and less than 0.1 ?m.

  • Patent number: 8803038
    Abstract: An apparatus for image formation comprises a fixing unit, first to fourth switching units, a DC power supply unit, an accumulating unit, a charging unit, and a switching control unit. The first switching unit switches the state of connection between the fixing unit and a commercial power source. The DC power supply unit supplies another electric load of the apparatus than the fixing unit with DC power. The second switching unit switches the state of connection between the DC power supply unit and the commercial power source. The third switching unit switches the state of connection between the charging unit and the commercial power source. The fourth switching unit switches the state of connection between the accumulating unit and the electric load. Based on the state of conduction of the first switching unit, the switching control unit switches the states of conduction of the other three switching units.

  • Patent number: 7523335
    Abstract: A job processing apparatus has a signal detecting section, a signal analyzing section, a job processing section, a main power supply portion, a first auxiliary power supply portion, a second auxiliary power supply portion, and a power control section. The main power supply portion supplies power to the job processing section. The first auxiliary power supply portion supplies power to the signal analyzing section. The first auxiliary power supply portion is smaller than the main power supply portion in power supplying amount. The second auxiliary power supply portion supplies power to the signal detecting section. The second auxiliary power supply portion is smaller than the main power supply portion in power supplying amount. The power control section, in power saving operation mode, switches off the main power supply portion and the first auxiliary power supply portion respectively.
