The present memory device includes first and second electrodes, an active layer; and a passive layer, the active and passive layers being between the first and second electrodes, with at least one of the active layer and passive layer being a doped a sol-gel. The body fluid suction reservoir further includes a lock having a hook and a release part and consisting of a member different from the two plates, by which lock the spring is held in a state compressed between the two plates, and the held state is releasable. Finally, the complex solution is pumped into the forming solution to form water-treatment particles. A water supply line injects a hot water stream within the throat downstream of the venturi member, wherein the hot water stream mixes with the fuel stream to atomize the fuel stream for vaporization within the internal combustion engine.
