A flush water tank apparatus supplying flush water to a flush toilet by using electrical power generated in the flush water tank apparatus, and a flush toilet apparatus including the flush water tank apparatus are provided. The flush water tank apparatus includes a discharge valve hydraulic drive portion, a discharge control device, an electromagnetic valve, a branching portion causing supplied tap water to flow into the discharge control device and into the water supply valve respectively, and a generator generating electrical power to operate the electromagnetic valve. The generator is provided on a water conduit in a downstream side of the branching portion, and on the water conduit in an upstream side of the water supply valve or in a downstream side of the water supply valve.

An absorbent article is disclosed having a topsheet, a backsheet joined with the topsheet, an absorbent core disposed between the topsheet and the backsheet, and a synthetic superabsorbent polymer derived from a first renewable resource via at least one intermediate compound, wherein said superabsorbent polymer exhibits a defined Saline Flow Conductivity value and Absorption Against Pressure value. Alternately, an absorbent article is disclosed having a synthetic polyolefin derived from a first renewable resource via at least one intermediate compound. The synthetic polyolefin exhibits defined performance characteristics making the polyolefin particularly useful in certain components of the absorbent article. Methods for making the aforementioned absorbent articles are also disclosed.
