Title: Maufacture of magnetic disk substrate comprising titanium
Inventor: SUENAGA HIROYOSHI
IPC: G11B5/66
Filed: 1990-03-09
Abstract: PURPOSE:To improve surface property and CSS characteristics and to improve adhesion property of a magnetic film by specifying the surface roughness of a titanium substrate and forming a hardened layer of specified hardness by sputtering on the substrate. CONSTITUTION:It is specified that the surface roughness of the titanium substrate is Rmax<=0.08mum, and the hardened layer formed by sputtering has hardness of Hv>=250 and 50 - 250mum thickness. By preliminarily specifying the surface roughness of the substrate to Rmax<=0.08mum, the surface state of the substrate becomes good after the hardened layer is formed. By specifying the hardness of the hardened layer to Hv>=250, CSS characteristics can be improved. Moreover, since the hardened layer is formed after the substrate is treated to have small roughness, no polishing process is needed after forming the hardened layer. Thus, good surface poperty and CSS characteristics can be obtained and adhesion property of a magnetic film is improved.

Title: Defatting method for melted carbonate type fuel cell
Inventor: TOI MASAAKI
IPC: H01M8/04
Filed: 1992-02-12
Abstract: PURPOSE:To carry out, with the temperature distribution being kept uniform, the defatting treatment of removing an organic substance contained in an electrolyte plate. CONSTITUTION:After a fuel battery is assembled using a tape formed electrolyte plate 1, one, or a mixture, of an inert gas N2 and a carbon dioxide gas CO2 is caused to flow into a cathode electrode 2 prior to commencement of the operation. Simultaneously, part of an outlet gas of the cathode electrode 2 is increased in temperature while it is being re-cycled via a re-cycle line 8 to an inlet side of the cathode electrode 2, and is defatted through thermal decomposition. Next, an air A is supplied on a bit-by-bit basis to the cathode inlet, by which defatting is changed over to defatting by oxidation. When, in this state, defatting is conducted and if no temperature rise occurs during this defatting operation, then the air A is re-cycled via the re-cycle line 8 and the temperature rise is caused, thereby doing defatting operation.
