A scoop is used to collect a liquid slurry upstream of an internal collection tank. The inertia track is interposed between the first and second fluid chambers, and is used as a fluid actuating plunger to move relative to at least one of the first and second chambers in response to vibration to pump fluid from the first chamber to the second chamber, and vice versa, through the inertia track. The body of the multi-purpose hanger having a plurality of appendages extending therefrom or having a plurality of orifices therethrough wherein the orifices are adjacent to one another in a predetermined pattern. The resonance frequency can be tuned and lowered by cutting open the short-circuit line or increased by short-circuiting the open conductor line. The groove volume ratio Rc of the crown rib, which is a ratio of the total volume of the grooves and sipes provided on the crown rib to the rib volume of the crown rib ,the groove volume ratio Rm of the middle rib, andthe groove volume ratio Rs of the shoulder rib satisfy the relationship,Rc<=Rm<Rs. Said first resistor has a second terminal connected the first input terminal of the output stage and said second resistor has a second terminal connected to the second input terminal of the output stage.
