The invention provides a magnetic memory device wherein an imbalance between variation threshold values for different magnetization directions of storage elements thereof such as a displacement of the center of an asteroid curve from the origin can be corrected readily without modifying the storage elements themselves. The refastenable pant includes a pair of elastomeric front side panels extending from the waist opening to each leg opening, a pair of elastomeric back side panels extending from the waist opening to each leg opening, and a pair of refastenable seams extending from the waist opening to each leg opening and positioned between the elastomeric front and back side panels. An amount of intake air flowing through the intake manifold is detected by an air flow meter disposed in the bypass pipe. Pushing the button on top of the dispenser into the button housing will cause the flow control valve to open the dispensing opening to deliver as much of the ingredients in the dispenser as the user desires.
