Abstract: PURPOSE:To carry a photographed film in a certain direction by allowing the photographed film to pass in a guide pipe, whose lower end is narrowed, by natural drop in an optional attitude and receiving temporarily it in its passing course to arrange the film in the advance direction or the direction orthogonal to it. CONSTITUTION:The photographed film is put down into a guide pipe 31 and is dropped by gravity. A film F is dropped with one corner turned down as shown by a dotted line in the figure and is brought into contact with a receiving plate 35 and is held in this state. Since some film is stopped by an end plate 31b of the guide pipe and the receiving plate 35 as shown by an arrow F' in the figure, seat belts 51 are rotated in the direction of an arrow to turn the film to F'. A shaft 52 is rotated by a motor to rotate seat belts. When the film is dropped onto the receiving plate 35, the optical beam from a light emitting device 41 to a photodetector 42 is intercepted to operate an electromagnetic solenoid, and the receiving plate is moved to open the lower end of the guide pipe. Thus, the film is arranged and discharged from the guide pipe.

Title: Manufacture of single-crystal film
Inventor: IWAMATSU SEIICHI
IPC: H01L21/20
Filed: 1991-09-04
Abstract: PURPOSE:To provide a long-life solar cell having an excellent conversion factor at a low cost by implanting a crystal seed of a single crystal in a portion of the surface of a solid body, forming a substrate with a solid-state material film such as a polycrystal formed in contact with the seed crystal, and by performing single crystallization via energitic beam irradiation in such a manner that the area in contact with the seed crystal is irradiated first and then other areas are scanned. CONSTITUTION:A seed crystal 12 for a single crystal composed of a solid-state single crystal is implanted in a portion of the surface of a solid body 11. A polycrystalline or amorphous film of the same material as the seed crystal 12 or a solid-state material film 13 is formed in contact with the seed crystal 12 to coat the surface of the solid body 11, forming a substrate. While a temperature slightly lower than the fusing point of the solid-state material film 13 is being kept, an energy beam is applied to the substrate. The beam is first applied to the area of the seed crystal 12 in contact with the solid-state material film 13. When the area is fused, the beam is shifted to another area, and this cycle is repeated. Thus, the solid-state material film 13 on the surface of the solid body 11 is substantially solidified through alternate fusing and cooling cycles, being turned to a single crystal on the surface of the substrate.
