摘要： A CaF2 buffer layer (3) is formed on a CaF2 (111) substrate (2) by an MBE method. Furthermore, a CuCl thin film is grown on the CaF2 buffer layer (3) by the MBE method while irradiating it with an electron beam to form an electro beam irradiation film (1a). Subsequently, a CuCl thin film is grown by the MBE method without the irradiation of electron beam to form an electron beam non-irradiation film (1b), thereby thus forming a CuCl thin film (a) including the electron beam irradiation film (1a) and the electron beam non-irradiation film (1b). Consequently, a CuCl thin film (1) exhibiting high planarity and crystallinity can be formed.

摘要： An internal-combustion engine is disclosed in which a pair of inlet valves and a pair of outlet valves are provided within the combustion chamber formed in each of a row of cylinders. A first ignition plug is disposed in the cylinder head within a central area of the combustion chamber in plan view. Second and third ignition plugs are disposed in the cylinder head at opposite peripheral portions of the combustion chamber positioned approximately along the first axis direction in plan view, the second and third ignition plugs are arranged so that the discharge electrode portions of the second and third ignition plugs being inclined inwardly of the combustion chamber in opposite directions and are substantially symmetrical relative with the first ignition plug in plan view. A line intersecting the discharge electrode portions of the second and third ignition plugs forms an oblique angle with the direction of the row of cylinders in plan view.
