    • A ventilating system that can make an air flow rate variable includes a DC motor that drives blades and a control circuit that controls the DC motor. The control circuit includes a first current detecting unit that detects a current flowing in the DC motor, a rotating speed detecting unit that detects a rotating speed of the DC motor, and a control unit that controls the DC motor based on a rotating speed detected by the rotating speed detecting unit and a current detected by the first current detecting unit. The current detecting unit includes a plurality of low-resistance resistors, detects a motor current by using divided voltages of the low-resistance resistors, and calculates a ventilation air flow rate based on the rotating speed detected by the rotating speed detecting unit and the current detected by the first current detecting unit.

    • A liquid container generally includes a main container body and a liquid delivery unit secured thereto. The main container body is formed of a flexible sheet and has an opening at its upper end to which the liquid delivery unit is sealingly secured. The liquid delivery unit includes a mouth portion positioned outside the main container body, a joining portion positioned below the mouth portion, a conduit portion extending from the joining portion toward the interior of the main container body, at least two flanges disposed above the joining portion, and at least two ribs positioned between the flanges. The ribs project in a direction perpendicular to front and rear surfaces of the main container body and extend in an axial direction of the conduit. The conduit is formed with a plurality of slots positioned inside the main container body and adjacent the upper opening.
