Title: Production of extra low carbon steel by rh type degassing apparatus
Inventor: SUETSUGU SEIICHI
IPC: C21C7/10
Filed: 1993-04-14
Abstract: PURPOSE:To circulate molten steel discharged into a ladle from a degassing vessel through a downtake tube to an uptake tube without generating stagnating part in the ladle. CONSTITUTION:The degassing vessel 1 is set at the position at which the uptake tube 2a shifts in the direction approaching to a ladle side wall 3a on the horizontal straight line connecting the center of the uptake tube 2a with the center of the downtake tube 2b so that the distance (d) between the center C1 of the degassing vessel 1 and the center C2 of the ladle 3 becomes at least 10% of the inner diameter L of the ladle to execute the degassing treatment to molten steel 4. The molten steel stream discharged from the downtake 2b can be circulated in the uptake tube 2a without generating the stagnating part in the ladle 9. By this method, as the decarburizing speed is improved, the degassing treating time can be shortened.

Abstract: PURPOSE:To grow a crystal excellent in crystallinity in specified positions by forming a silicon thin film, subjecting the film to solid growth, covering such specified positions with a mask, ion-implanting neutral elements to make amorphous the unmasked portions of the silicon thin film, removing the mask, and performing the second solid growth. CONSTITUTION:A crystalline or polycrystalline silicon thin film 1 is formed on the insulating layer 4 formed on a substrate 3. The silicon thin film 1 is subjected to ion implantation and made amorphous. The thin film 1 is thereafter subjected to solid growth to form crystal grains 1a predominant in the plane (111) orientation. A mask 2 is formed to cover specified positions on the silicon thin film 1. Neutral elements are ion-implanted in the entire surface of the thin film 1 over the mask 10 to make amorphous the unmasked portions of the film 1. Subsequently, the mask 2 is removed, and the second solid growth is performed by annealing. This forms single crystal grains of large size excellent in crystallinity.

Title: Formation of phosphor screen of color picture tube and light exposure equipment therefor
Inventor: INOUE MASACHIKA
IPC: H01J9/227
Filed: 1986-04-18
Abstract: PURPOSE:To form a required phosphor screen without lowering tube characteristics and easily by irradiating light from a long light source on a panel, moving the panel in the longitudinal direction of the long light source. CONSTITUTION:A panel 1 is light-exposed, being moved in the direction of throughhole array of a shadow-mask 2 arranged through a bridge i.e. in the longitudinal direction of a long light source. This can sufficiently correct the constriction of stripes generated by the influence of the bridge of the shadow- mask 2. Besides, the allowable ranges of the moving distance and moving speed of the panel 1 is wide. Therefore, the adjustment for correcting the constriction becomes easy, resulting that the stripes almost without constriction can easily be formed. And since this method is that of concurrently light-exposing the whole face of the panel 1, the exposure time can be shortened. The variation of the positional relationship between the panel and a landing correcting lens is small and also the tube characteristics do not happen to be lowered.
