A cleaning member for cleaning an image carrier. The semiconductor integrated circuit has a first switch circuit between a first reception terminal and the first noninverting input terminal. In addition, the system also has areas that may be used for advertising programs, products or services. The drive rod connected to the actuator via a linkage mechanically connects the actuator to the drive rod. The electromagnetic flow meter and method measure the axial velocity profile of a conducting fluid by dividing the flow cross section into multiple pixels and determining the axial velocity of the conducting fluid in each pixel.
