摘要： An output of an electric driven blower (2) in a cleaner main body (1) is controlled in response to a detection value of a pressure sensor (12) which detects an operation condition in the cleaner main body (1). A change-over level setting value (C₁ , C 1′ ) is provided as an control value for the sensor (12) so as to form a judgement point for changing over a control condition of the blower. A return level setting value (C R′ C 2′ ) is provided as a control value for the sensor so as to form a judgement point for returning to a previous control condition of the blower (2) from a changed-over condition of the blower. When the detection value of the sensor (12) is more than the change-over level setting value, the return level setting value is set higher than the change-over setting value, thereby the output of the blower (2) is increased, or the return level setting value is set a lower than the change-over level setting value, thereby the output of the blower is decreased.

摘要： In order to provide an electrophotographic image forming system characterized by a mechanism of stabilizing the behavior of the tip of the form when the form with unfused colored particles (toner) deposited thereon is fed to the fusing device, the present invention has a form posture correcting protrusion (19h) provided on the non-printing area of the surface of the form with unfused colored particles (toner) deposited thereon inside the feed path of the form with unfused colored particles (toner) desposited thereon, so that form behavior can be controlled when the form is fed to the fusing device (19). Furthermore, the present invention has a form guide (19d, e) provided on the form ejection side of the fusing device (19) to control the behavior of the form moving in the direction of being wound on the fusing roller. Furthermore, the present invention has a form guide (182) provided inside the feed path of the form with unfused colored particles (toner) deposited thereon, so as to contact the end of the form on the surface with unfused colored particles (toner) deposited thereon, thereby ensuring that form behavior can be controlled when the form is fed to the fusing device.

摘要： In a vacuum cleaner, both static pressure H data and a variation width ΔH in the static pressure appearing when a suction port is operated are detected from a pressure sensor (8) provided at a rear side of a filter (7) within a main body (2) of the vacuum cleaner; a current variation width Δpbi appearing when the suction port is operated is detected from a current of a nozzel motor (26) for driving a rotary brush (10) stored in a power brush suction port; an air quantity at the suction port is calculated from the current, rotational speed of a fan motor (FM) and static pressure ; command values are newly obtained by performing a fuzzy calculation with the variation width Apbi, static-pressure command value Hcmd ; the variation width ΔH and the static-pressure command value Qcmd ; the variation width Δpbi and static-pressure command value Hcmd ; and also the variation width ΔH and static-pressure command value Qcmd as the input thereto ; the rotational speeds of the fan motor (FM) and nozzel motor (26) are controlled from the result of the command values ; and further optimum air suction force is automatically obtained, depending upon the suction port under use and cleaning floor plane.
