Title: Hot working method for two-phase stainless steel
Inventor: MAEHARA YASUHIRO
IPC: C22C38/40
Filed: 1985-04-19
Abstract: PURPOSE:To make possible the production of a product having an intricate shape at a high yield without requiring machining by working a two-phase stainless steel consisting of Cr-Ni in a non-oxidizing gaseous atmosphere under specific temp. and strain rate conditions. CONSTITUTION:The Cr-Ni stainless steel contg. 15-35% Cr, 4-18% Ni and 0.01-6.0% Mo and having 2 phases; ferrite phase and austenite phase has not only excellent corrosion resistance but strength, toughness and weldability as well but is inferior in workability and therefore the working to the product having the intricate shape by hot working is difficult. Such 2-phase stainless steel is therefore heated to the temp. region of iota700 deg.C and the temp. at which the single ferrite phase is formed <=-100 deg.C in the non-oxidizing atmosphere of gaseous N2 or N2+gaseous Ar and is subjected to plastic working such as forging, bulging, drawing and extruding under the conditions of 10<-6>-10l/sec strain speed during deformation in the stage of hot working the above-mentioned stainless steel. The working to the product having the intricate shape with the good raw material yeild is thus made possible.

Title: Magnetic recording and reproducing plate
Inventor: INOUE SATORU
IPC: G11B5/73
Filed: 1982-05-18
Abstract: PURPOSE:To obtain a magnetic disk, etc. which is suited especially to the high- density recording with excellent strength, by bonding two substrates obtained by vapor depositing a ferromagnetic and metallic thin film on a single side of a comparatively thin polymer substrate to a comparatively thick polymer forming product substrate of the same material as said two substrates at the side opposite to a magnetic film. CONSTITUTION:A ferromagnetic and metallic thin film 4 is formed by a vacuum vapor deposition on a single side of a comparatively thin polymer substrate 3. Two sheets of such substrate 3 are bonded on both sides of a forming product substrate 5 having a comparatively large thickness and the same material as the substrate 3 by means of an adhesive 6 and with the film 4 set outside. This bonded substrate is consecutively blanked into a desired shape including a circle, an oblong, etc. in order to obtain a floppy disk, a magnetic card, etc. The substrate 3 is adhered close to a cooling drum owing to a small thickness of the substrate 3 when the film 4 is vapor deposited, and therefore the vapor deposition is carried out evenly with good smoothness. Furthermore the mechanical strength is increased with junction of a substrate 5. Thus it is possible to obtain simply and with a low cost a high-density recording/reproducing plate.

Filed: 1999-03-26
Abstract: PROBLEM TO BE SOLVED: To provide a dodging effect without lowering contrast even when low frequency components (blur images) are insufficiently obtained. SOLUTION: An LPF 8 for extracting the low frequency components from image data from an RGB/YCC conversion part 5 and a subtractor 10 for generating intermediate frequency/high frequency components by subtracting the low frequency components from the image data are provided. Then, while gradation- compressing the low frequency components obtained in the LPF 8 in an LUT 9, the intermediate frequency/high frequency components obtained in the subtractor 10 are emphasized in the LUT 11.  Thus, even when the blurring degree of the low frequency components is insufficient, the intermediate frequency/high frequency components slightly remain in them and even the intermediate frequency/high frequency components are compressed in the LUT 9, by composing the gradation-compressed low frequency components and the emphasized intermediate frequency/high frequency components in a composition part 12, the compressed portion of the intermediate frequency/high frequency components are supplemented and the lowering of the contrast is evaded.
