    • A capacitive type semiconductor accelerometer has an intermediate silicon plate of n type conductivity including a movable electrode constituting a pendulum mass formed within the intermediate silicon plate and supported thereby via a beam so as to permit movement in a direction perpendicular to its plane. A first conductive island is formed within the intermediate plate and is immovably supported thereby via a first insulating leg so as to be isolated therefrom, and an upper glass plate is anodic bonded to the intermediate silicon plate. A first stationary electrode is formed on the upper glass plate at the position facing one face of the movable electrode with a predetermined gap. A lower glass plate is anodic bonded to the intermediate silicon plate and a second stationary electrode is formed on the lower glass plate at the position facing the other face of the movable electrode with a predetermined gap. First, second and third pads are disposed in common on the lower glass plate at the outside of the intermediate silicon plate, the first pad being electrically connected to the first stationary electrode via a first thin film lead formed on the lower glass plate and the first conductive island, the second pad being electrically connected to the movable electrode via a second thin film lead formed on the lower glass plate and the intermediate silicon plate and the third pad being electrically connected to the second stationary electrode via a third thin film lead formed on the lower glass plate.

    • A liquid hydrocarbon such as a natural gas liquid generally contains a small amount of mercury in a state of elemental mercury, ionized mercury, ionizable mercury compounds, which are requested to be removed thoroughly. Further, organic mercury compounds are contained in some natural gas liquid and other liquid hydrocarbons depending on their district of production, and its removal is also necessary.Already known adsorbents can adsorb elemental mercury and organic mercury compounds in a liquid hydrocarbon, but they hardly adsorb ionizable mercury compounds and ionized mercury derived from the ionizable mercury compounds.According to the preesent invention which comprises contacting the liquid hydrocarbon with a sulfur compound represented by a general formula MM'S.sub.x, wherein M is selected from a group consisting of alkali metal and ammonium radical, M' is selected from a group consisting of alkali metal, ammonium radical and hydrogen an x is a number of at least 1, the sulfur compound and mercury in the liquid hydrocarbon reacts to form mercury sulfide which is insoluble in the liquid hydrocarbon to be separated therefrom.If the liquid hydrocarbon contains organic mercury compounds together with elemental mercury ionized mercury and ionizable mercury compounds, the above-mentioned process is to be combined with a process of contacting the liquid hydrocarbon with an adsorbent comprising heavy metal sulfide to adsorb the organic mercury compounds together with the mercury sulfide which is formed in the above-mentioned process.
