A solid state relay composed of a series connected pair of LDMOSFETs has a minimized output capacitance. Each LDMOSFET is configured to have a silicon layer of a first conductive type, a drain region of the first conductive type diffused in the top surface of the silicon layer, a well region of a second conductive type diffused in the silicon layer in a laterally spaced relation from the drain region, and a source region of the first conductive type diffused within the well region to define a channel extending between the source region and a confronting edge of the well region along the top surface of the silicon layer. Each LDMOSFET is of an SOI (Silicon-On-Insulator) structure composed of a silicon substrate placed on a supporting plate, a buried oxide layer on the silicon substrate, and the silicon layer on the buried oxide layer. The well region is diffused over the full depth of the silicon layer to have its bottom in contact with the buried oxide layer, so that the well region forms with the silicon layer a P-N interface only at a small area adjacent the channel. Because of this reduced P-N interface and also because of the buried oxide layer exhibiting a much lower inductive capacitance than the silicon layer, it is possible to greatly reduce a drain-source capacitance for minimizing the output capacitance of the relay in the non-conductive condition.

A liquid separator system having a gas phase zone, an aqueous phase zone and a denser liquid zone is used to separate mixtures of fluids. The separator can be used for separating molten sulfur from liquid redox solution or reslurry water. The system includes a vessel with a top part and a bottom part. The vessel has a larger diameter at the top part than at the bottom part. The system also includes an inlet for introducing a redox solution or reslurry water and molten sulfur, which is denser than redox solution or reslurry water, into the vessel. An outlet near the bottom part of the vessel allows a flow of the molten sulfur from the vessel. An interface control structure senses an interface level between the redox solution or reslurry water and the molten sulfur, and the interface control structure controls the flow of molten sulfur from the outlet. The interface control structure is adjusted to optimally alter the vertical height of the interface level within the vessel so that the residence time of the molten sulfur in the vessel does not decrease as the sulfur production throughput decreases, and so that the interface area of the molten sulfur and the redox solution is reduced as the sulfur throughput decreases. A pressure controller monitors the pressure in the vessel and adds or removes gas from a gas phase zone in the vessel to maintain a predetermined pressure regardless of the vertical height of the interface.
