    Abstract: A power consumption calculation apparatus is disclosed, including: a work load measurement part, a management part, and a power consumption calculation part. The work load measurement part measures a work load of a job executed by an image forming apparatus and records a measured value, at predetermined time intervals. The management part manages state transition data indicating power consumption and a required time for each of states of the image forming apparatus which transits in response to an execution of each job. The power consumption calculation part calculates a power consumption amount corresponding to one job execution at each predetermined time interval when it is determined that the job is executed, based on the measured value and the state transition data.

    Abstract: A charging member having a support, a conductive elastic layer formed on the support and a surface layer formed on the conductive elastic layer, wherein the surface layer contains a polysiloxane having an acrylic group and an oxyalkylene group. This provides a charging member to the surface of which toners and external additives used in the toners can not easily cling even because of repeated use over a long period of time and which therefore enables charging and image reproduction which are stable over a long period of time, even when used in the DC contact charging method; and further provides a process cartridge and an electrophotographic apparatus which have such a charging member.

    Abstract: The present invention provides a high-efficiency absorption refrigerating machine which can recover heat from a heat source and can efficiently recover heat from an internal cycle. The absorption refrigerating machine includes an evaporator, an absorber (A), a condenser (C), a high-temperature regenerator (GH), a low-temperature regenerator (GL), a low-temperature solution heat exchanger (LX), and solution paths and refrigerant paths by which these units are connected. The absorption refrigerating machine further comprises two branch solution paths branched from a solution supply path through which a dilute solution is introduced from the absorption (A) to the high-temperature regenerator (GH). On one of the branch solution paths, there is disposed a drain heat exchanger (DX) operable to perform heat exchange between the dilute solution in the branch solution path and an exhaust heat source which has heated the high-temperature regenerator (GH).

  • Publication number: 20060073626
    Abstract: A method for manufacturing an optical element comprises a step of press molding an optical element material 6 disposed between an upper press head (7) and its paired lower press head (8), wherein in the upper press head (7) and/or the lower press head (8) is formed a groove-like component that forms a non-cylindrical face or a cylindrical face as an optically effective component in the optical element material (6). This makes it possible to obtain an optical element with stable face shape precision, boosts productivity, and is also advantageous in terms of cost.
