An imager in which two adjacent pixels share row and reset lines and a row selection circuitry while the output transistors of the two pixels are configured as a differential amplifier. The output of the first connector is connected to an input of a first functional unit. A power spectral density curve of a standardized model, formed under a same exposure process of the detection sample, can be obtained. A request-status-information acquiring portion acquires, from the device, request status information indicative of a request status of the predetermined request. For example, the transmission may be used in a motorized vehicle such as an automobile, motorcycle, or watercraft, a non-motorized vehicle such as a bicycle, tricycle, scooter, exercise equipment or industrial equipment, such as a drill press, power generating equipment, or textile mill. A pole piece couples the inlet tube to one end of a non-magnetic shell having a valve body coupled to the opposite end.
