A component which is known to have particular degradation characteristics is instrumented to provide an electrical potential across a section in which a degradation is likely to occur. On the outside of RESURF region, a second logic circuit region is formed, which is applied with the driving voltage level required for driving a second logic circuit with respect to the ground potential. The valve head may be driven by the coil between a first position wherein the valve head at least partially obstructs the fluid passage and a second position wherein the valve head permits greater fluid flow in the fluid passage to control fluid flow through the fluid passage. The interior container includes a filter to filter the water as it leaves the water tank and enters the bowl and as it flows from the bowl into the interior container.
