The single crystal of thin film on the surface of the polycrystalline material is used as a seed crystal, and the polycrystalline material is processed into a single crystal by a solid-phase reaction. The single crystal on the surface of the polycrystalline material, for example, is formed by irradiating it only in the vicinity of the surface layer of the polycrystalline material with laser, so that it is melted, precipitated in a solid phase and processed into a single crystal. A thin film-forming substance is partially supplied from the outside, reacted with the polycrystalline material in a proper atmosphere, and the single crystal of thin film is formed on the surface of the polycrystalline material.

Abstract: PURPOSE:To introduce an object to be processed such as food and others in a packaging machine in a lump by a method wherein one open end of a cylinder, in which the object to be processed is thrown in, is arranged at the upper side, and a shutter is provided at the open end on the bottom, and the cylinder is being moved as the constitution. CONSTITUTION:An object to be processed is thrown in the internal space (1e) from an open end (1c) on the top of a cylinder l. The passing of the object to be processed through a specified passing location 3, which is located directly above the open end (1c) on the top is detected by a sensor 2. At this time, the cylinder 1 keeps an approximate rotary motion at a fixed speed, and a shutter 4 is closed. The object to be processed which is thrown in the cylinder 1 is pushed to the central direction of the cylinder 1 every time it touches the inner surface of the cylinder 1, and at the same time, the object to be processed instantly separates from the inner surface at the opposite side of the cylinder 1. As the result, the object to be processed is converged to the central direction. In the meantime, the object to be processed which is thrown in the vicinity of the center of the cylinder 1 drops to the shutter 4 while keeping the position around the center. The retardation time between the detection time of the sensor 2 and the opening/closing time of the shutter may be appropriately selected depending on the content and others of the object to be processed.
