  • Publication number: 20120224893
    Abstract: A media stripper mechanism includes a shaft, one or more first stripping members, and one or more second stripping members. The shaft extends in an axial direction thereof parallel to a rotational axis of the rotary member. Each of the one or more first stripping members is a pneumatic nozzle that has a proximal end thereof supported on the shaft, and a distal, free end opposite the proximal end thereof pointing toward the rotary member to direct compressed gas toward the nip along the rotary member for stripping the recording medium from the rotary member. Each of the one or more second stripping members is a non-contact finger that has a proximal end thereof supported on the shaft, and a distal, free end opposite the proximal end thereof pointing toward the rotary member to assist in stripping the recording medium from the rotary member without contacting the rotary member.

  • Patent number: 8200384
    Abstract: An input/output control unit receives two temperature values from first and second temperature sensors, respectively, and calculates a temperature difference that is an absolute value of a difference between the two temperature values. The input/output control unit stores a map determining a relationship between temperature values and target values of input powers (or output powers) of the first and second batteries required for keeping the temperature difference. Based on this map and the two temperature values received from the first and second temperature sensors, respectively, the input/output control unit determines the target values of the respective input powers (output powers) of the first and second batteries. A hybrid control unit controls an inverter unit and a booster converter such that the values of the powers input/output to or from the first and second batteries attain the target values, respectively.

  • Patent number: 8188710
    Abstract: In charging first and second power storage devices from a charging station, an inverter ECU controls first and second inverters to convert AC power received at first and second neutral points into DC power and output the DC power to a power supply system. A converter ECU converts in voltage the electric power received from the first and second inverters to be charged and outputs the converted electric power to the first and second power storage devices, and for low temperature, controls first and second converters to allow the first and second power storage devices to communicate electric power therebetween.

  • Patent number: 8134334
    Abstract: Light applied from an illumination unit illuminates a space formed of an accommodation unit, and facilitates a user's operation of coupling a charging connector to an electric power-receiving unit. When a lid unit is in a closed state, a part of the light applied from the illumination unit toward the accommodation unit transmits through a light transmission member provided at the lid unit and leaks toward a space outside a vehicle body. The leaked light enables a user to visually perceive the position of the charging port at a glance even if the lid unit is in the closed state.

  • Publication number: 20120051805
    Abstract: A media stripper for use with a pair of first and second, opposed rotary members includes a stripper finger and a rotation restriction mechanism. The stripper finger has an operational edge thereof disposed adjacent to the first rotary member to strip a recording medium from the first rotary member. The stripper finger is rotatable around a pivot axis parallel to a rotation axis of the first rotary member either in a first rotational direction in which the operational edge approaches the first rotary member, or in a second rotational direction in which the operational edge approaches the second rotary member, so as to establish an operational position thereof relative to the first rotary member. The rotation restriction mechanism is disposed for contact with the stripper finger to restrict rotation of the stripper finger in the second rotational direction upon establishment of the operational position of the stripper finger.

  • Patent number: 8112022
    Abstract: In a fixing device, a controller switches a pressing member between a pressure application state to contact the pressing member against a fixing member and a pressure release state to separate the pressing member from the fixing member. The controller starts rotation of the pressing member before the pressing member contacts the fixing member in the pressure application state, when the pressing member switches from the pressure release state to the pressure application state. An oil applier includes an oil pan and an oil regulating member. The oil pan is provided under the pressing member to contain oil in which the pressing member is dipped. The oil regulating member is provided downstream from the oil pan in a direction of rotation of the pressing member to contact the pressing member to regulate an amount of oil adhering to the pressing member.

  • Publication number: 20110140659
    Abstract: A power management system is a system for performing power management on a management subject apparatus that includes a charging unit for charging a storage apparatus installed in a vehicle. The power management system includes: a detection unit that detects a power consumed by the management subject apparatus; an adjustment unit that adjusts a charging power charged to the vehicle from the charging unit; and a control unit that controls the adjustment unit. The control unit determines an allowable power that can be supplied to the vehicle from the charging unit, notifies the vehicle of the allowable power, and controls the adjustment unit such that a power transmitted to the vehicle is reduced when a response to the notification of the allowable power is not received. With the system according to the invention, restrictions on charging subject vehicles can be alleviated without increasing a charging capacity of a charging facility.
