Abstract: A high-voltage bipolar semiconductor controlled rectifier (SCR) includes an emitter region having a first polarity and overlying a base region having a second polarity different from the first polarity; a collector region having the first polarity and lying under the base region; an anode region having the second polarity; a first sinker region having the first polarity and contacting the collector region, wherein the anode region is between the first sinker region and the base region; and a second sinker region having the first polarity and contacting the collector region, the second sinker region lying between the anode region and the base region, wherein an extension of the anode region extends under a portion of the second sinker region.

Abstract: An electro chemical conversion cell that can break down certain gasses to provide ozone and monovalent oxygen from a supplied volume of a suitable 02-containing gas. The conversion cell is provided with at least one metal mesh electrode within a generator reaction chamber, and a power supply which is adapted to supply a high alternating electric current voltage to at least partially break-down O2 in the input gas to yield ozone. A fluid flow passage extends through the reaction chamber as a generally elongated passage through the reaction cavity. The fluid flow passage extends from an upstream end, where the O2-containing gas is initially supplied into the housing, to a downstream end where treated gas either flows outwardly therefrom under pressure or is evacuated from the housing. In a simplified construction, the fluid flow passage is delineated by a series of electrically insulating plates and/or spacers which are used to partition the reaction cavity.
