Abstract: PURPOSE:To remove an oxide film formed in an interface between a GaAs semiconductor and an AlN film excellently, by performing a hydrochloric acid treatment process on the surface of a substrate made of a single crystal of gallium arsenide immediately before forming an aluminum nitride film. CONSTITUTION:Immediately before a semi-insulating GaAs substrate 1 is set on a sputtering apparatus, the substrate is treated by aqueous solution of hot hydrochloric acid. Thereafter washing by water and drying are performed. Then, the semi-insulating GaAs substrate 1 is set on the sputtering apparatus, and an AlN film 2 is formed on the semi-insulating GaAs substrate 1. A mask 3 made of SiO2 and the like, wherein an opening part is selectively fromed, is provided on the AlN film 2. Through the opening part, e.g., Si ions are implanted. Then, the mask 3 is removed, and an AlN 5 is further formed on the AlN film 2.

Abstract: PURPOSE:To attain highly accurate metering of gas fuel with a simple structure by forming the structure such that a metering part, formed of a fine annular clearance, is provided in the downstream of a seat part between a main unit and a valve while opening the valve against a spring by energizing an electromagnetic device. CONSTITUTION:When an armature 11 is attracted to the upper surface of a stator 9 against a spring 6 by energizing a coil 90, a seat surface 41 of a cup- shaped head 4b is separated from a seat surface 101 of a valve unit 1a by lowering a valve 4 through a pressing bar 11a and a pressure receiving member 12. In this way, gas fuel is allowed to flow in an enlarged part 100 via a clearance between seat surfaces 41, 101 from a passage hole 10 by connecting an inlet part 2 to the enlarged part 100. Since a metering part 5 of fine annular space is formed by a ring-shaped protrusive part 102 in this enlarged part 100, gas fuel is throttled by this metering part 5 and press-fed to an engine from an outlet part 3 by pressing down a check valve 7 with an amount metered by throttling of this metering part.
