Title: Production of oxide superconducting thin film
Inventor: FUJINO KOZO
IPC: C30B33/04
Filed: 1993-04-19
Abstract: PURPOSE:To obtain an oxide superconducting thin film, having the high critical current density and good in crystallinity by forming an interlayer on a metallic substrate and then forming the oxide superconducting thin film on the interlayer while applying an alternating voltage to the metallic substrate. CONSTITUTION:An interlayer (e.g. YSZ) for preventing a substrate from oxidizing is preformed on the polycrystalline metallic substrate 2. The resultant substrate 2 is then installed on a heating stage 1 and heated and an alternating voltage is subsequently applied from an AC power source 7 through voltage terminals 3 to the substrate 2. The top surface of a target 4 composed of a sintered compact of an oxide superconductor is simultaneously irradiated with excimer laser beams 5 to deposit particles 6 scattering from the target 4 on the substrate 2 and the oxide superconducting thin film is formed. Thereby, since the alternating voltage is applied to the polycrystalline substrate 2 during the formation of the film, an induced current is generated in the oxide superconductor. As a result, the oxide superconductor is the stablest in the direction for most easily flowing the current, i.e., to be a single crystal. As a result, the oxide superconductor grows by arranging the crystal axes.

Filed: 1981-06-12
Abstract: PURPOSE: To eliminate troubles arising from coke oven cleaning, by attaching a door cleaner in such a way that a scraper may come in contact with the surface to be cleaned only when the cleaner moves downward and may escape in an opposite direction when the cleaner moves upward.  
     CONSTITUTION: A scraper holder 2 fitted in a frame 1 is operated by a hydraulic cylinder and moves up and down. A holding arm 3 for a scraper 4 is attached pivotally to a shaft 5 and a stopper pin 6 prevents counterclockwise rotation of the arm 3 (scraper 4). When the holder 2 comes down in the direction of an arrow a, tar and other deposits on the brick surface of door A are scraped off, and counterclockwise rotation of the scraper 4 is hindered by the stopper pin 6. When the holder 2 reaches the lowest limit of descent, it again moves upward, with the scraper 4 turning in a clockwise direction and never taking a scraping- up action.
