Title: Preparation of gallium nitride fluorescent substance, preparation of gallium oxide and gallium oxide
Inventor: SUDA JUNKO
IPC: C09K11/62
Filed: 1998-12-28
Abstract: PROBLEM TO BE SOLVED: To provide a preparation process of a GaN fluorescent substance having a good crystallinity. SOLUTION: Gallium hydroxide is obtained by adding ammonia dropwise to gallium nitrate hydride. This gallium hydroxide is introduced into an oven pre-heated to 800 deg.C to remove moisture at once. Spongy, porous gallium oxide having a specific surface area which is twice as large as that of conventional gallium oxide, is obtained. This porous gallium oxide is allowed to react in an ammonium atmosphere at 1,000 deg.C for two hours to obtain a powdery GaN. Conventional GaN prepared using conventional gallium oxide as a material had a black pigmentation containing tan-colored parts. GaN obtained here is tan-colored with no blackened part. GaN obtained here has a sphere-like form wherein the particle size is distributed within from 0.5 to 2 μm, and was proved to have an improved crystallinity than that of the conventional GaN through an X-ray diffraction analysis.

Title: Magnetic recording medium and its manufacture
Inventor: SAIKI KOJI
IPC: G11B5/65
Filed: 1990-12-28
Abstract: PURPOSE:To form a magnetic film having large in-plane anisotropy so as to improve the reproducing output, recording density, low-noise property, and durability of a magnetic recording medium by depositing the partially oxidized film of cobalt on a chromium base layer provided on the substrate of the magnetic recording medium. CONSTITUTION:When a partially oxidized film of cobalt is formed by sputtering on a substrate composed of an organic high polymer plate or sheet, metallic plate, glass plate, etc., the in-plane coercive force of the oxide film gradually drops while the sputtering is repeated under the same condition and the oxide film becomes a vertically magnetized film. In order to solve this problem, a thin chromium base layer is provided. When the thickness of the chrome base layer is increased to 100-500Angstrom , an oxide film having large in-plane anisotropy is obtained. In addition, the durability of the magnetic recording medium is also increased against magnetic heads which slide on the recording medium due to the harness of the partial oxide. Moreover, appropriate recording and reproduction can be performed with a ring-type head.

IPC: H04N1/405
Filed: 1989-11-13
Abstract: Apparatus for a digital screener (30) and methods for use therein are disclosed for producing relatively smooth halftone dots at substantially any arbitrary screen angle and for suppressing a substantial source of screener induced Moire patterns that would otherwise appear in a reproduced color image generated by a raster based marking engine (20). Specifically, relatively smooth dots are generated and this Moire is suppressed by randomly varying the dot fonts that are used to write successive halftone dots in the screened image. A pseudo-random value is used to select one of a number, illustratively sixteen, of available halftone dot fonts. Each dot font can take on nearly any pattern (shape) as long as it is somewhat different from that of the other fonts, provided the patterns of all the dot fonts are relatively smooth, apart from normal dot boundary irregularities due to quantization. Once a particular font is chosen to produce any halftone dot in the screened image, no random variations are added to the font pattern. The random variation inherent in the selection of any particular dot font coupled with the dissimilarity among the patterns for the individual dot fonts, for any given contone value, substantially suppresses Moire patterns that might otherwise appear in the screened image. Moreover, writing a selected dot font without imparting any random variations to the shape of the font itself avoids any excessively jagged halftone dot edges other than dot boundary irregularities which normally occur from quantization. The use of sheared halftone dot fonts and a halftone dot font selection process that relies on constrained randomization are also disclosed herein.
