Title: Optical data recording medium
Inventor: KAWAI SHOICHI
IPC: G11B7/24
Filed: 1992-12-26
Abstract: PURPOSE:To improve the C/N ratio by increasing the modulating degree of amplitudes. CONSTITUTION:An optical data recording medium 10 is a rewritable optical data recording medium, having a multi-layered lower protecting film 2 of four layers, a recording film 3, an upper protecting film 4 and a reflecting film 5 sequentially layered on a surface of a substrate 1 where a pregroove is formed. At the opposite surface is formed a multi-layered reflection preventing film 6 of a reflection preventing film (I) 6a and a reflection preventing film (II) 6b. Owing to the multi-layered reflection preventing film 6, the cast light is never reflected at the surface of the substrate in the optical data recording medium 10. Accordingly, the reflectance of a part of a lower reflectance of a recorded part or an erased part of the recording film can be decreased without lowering the reflectance of a higher reflectance of the recorded part or erased part of the recording film of the optical data recording medium. Eventually, the modulating degree of amplitudes of the optical data recording medium can be increased, thereby improving the C/N ratio and reducing reading errors.

Filed: 1998-12-21
Abstract: PROBLEM TO BE SOLVED: To secure the dispersibility of dots among colors in a low gradation area and to improve image quality by providing a multi-valuing means for performing a halftone processing capable of securing the dispersibility of the dots among the respective colors for a specified color or the like. SOLUTION: In the case of judging that both of gradation values DC and DM are smaller than a value 3, the ON/OFF of the dots is judged by using a dither method so as to sufficiently dispersedly form the dots of light cyan and light magenta (S215). That is, a CPU compares the size relation of the gradation value DC of the light cyan and a threshold THD (S260), and in the case that the gradation value DC is equal to or more than the threshold THD, judges that the dot is to be ON and substitutes the value 1 to a result value RDC (S270). In the case that the gradation value DC is smaller than the threshold THD, it judges that the dot is to be OFF and substitutes the value 0 to the result value RDC (S265). Also, the threshold THD is supplied for each pixel by a dither matrix. Then, the CPU performs the halftone processing for the light magenta.

Title: Manufacture of surface-treated steel plate excellent in soot decmposing property
Inventor: IWAMIZU YOSHIHARU
IPC: B32B15/08
Filed: 1997-12-15
Abstract: PROBLEM TO BE SOLVED: To impart a decomposing property for tar-like carbon or soot, and prevent cracks or pores from being generated on the coat by using a coating containing a specific quantity of a Cu powder added to a nonvoltile content and heating a steel plate at a specific temperature of a temperature arriving at the plate. SOLUTION: A Cu powder is added to a coating containing a silicon polymer as a principal component and also an Mo organic metal compound or heteropoly acid. The content of the Cu powder to the coating is 1-20 mass % to the nonvolatile content. After applying the Cu powder-added coating to a steel plate in such a manner that the thickness of the dried coat is as specified thickness, the steel plate is heated at 300-450 deg.C, the temperature arriving at the steel plate. Thus the rate of oxidation at which Mo is oxidized into MoO3 is high, even when the heating temperature is lowered to 300-450 deg.C, by adding the Cu powder to the coating, and the soot decomposition property is improved.
