Title: Manufacture of magnetic metal powder retaining dispersion property
Inventor: TAKAHASHI SEIICHI
IPC: B22F9/20
Filed: 1989-01-30
Abstract: PURPOSE:To enhance a dispersion property by installing a process in which an iron oxyhydroxide whose surface has been denatured is kneaded and treated in an alcohol-based solvent after the ratio of the alcohol-based solvent ROH to water H2O has been set to a specific ratio. CONSTITUTION:An iron oxyhydroxide whose surface has been denatured is kneaded and treated in an alcohol-based solvent after, as the ratio of the alcohol-based solvent ROH to water H2O, their distribution is set to ROH:H2O =100:0 to 50:50. It is kneaded and treated under a distribution of A/B=60/40 to 30/70 in a ratio of the iron oxyhydroxide A to a total amount B of alcohol + water. Then, the treated iron oxyhydroxide is dried; after that, it is baked temporarily and reduced to form a ferromagnetic powder. In order to denature the surface of the iron oxyhydroxide, one or more kinds of elements selected from elements such as B, Mg, Al, Si, P, Ti, Zn, Cr, Mn, Co, Ni, Cu, Zr, Sn, Pb, Ca, Ba and the like are applied to the surface of the iron oxyhyroxide. Thereby, it is possible to form a ferromagnetic material metal iron fine particle which retains a dispersion property and an unfastening property even after a temporary baking process and a reduction process.

Title: Photomask and its mask handler
Inventor: NAKAMURA SHINICHI
IPC: G03F1/66
Filed: 1981-02-09
Abstract: PURPOSE:To handle a photomask without touching it directly, by burying a frame made of a ferromagnetic matter along the four sides in a transparent substrate so as to form a closed loop. CONSTITUTION:A frame 3 made of a ferromagnetic matter is buried along the four sides of a transparent substrate 1 so as to form a closed loop. Thus a photomask is formed. At the same time, an electromagnet 4 having two magnetic poles of a half-cut shape obtained by longitudinally cutting a hollow cylinder is formed with a space equal to the space between two opposing sides of the frame 3. A coil 6 is wound round the center part of the magnet 4 to minimize the magnetic flux leaking outside to form a mask handler. Then a switch 7 of a knob 5 connected to the magnet 4 is turned on to properly control the level of a current flowing to the coil 6. Thus a magnetic circuit is formed between the magnet 4 and the frame 3.
