Filed: 1994-08-05
Abstract: PURPOSE:To enable displaying of magnified images by subjecting electric signals of images to digital processing to form plural pieces of image data displayable with plural display devices, connecting plural pieces of the image data with plural display devices and displaying the connected image data. CONSTITUTION:The electric signals of the original image photographed by a camera are converted to digital signals by the resolution higher by a factor of the number of units than the resolution of the base image of one unit of the display device at every one scanning line. These digital signals are preserved in a large-capacity frame memory 14. An image data resolving device 15 reads the digital image data of every one scanning from the memory 14, forms the digital image data of one scanning line by resolving the data to the data for the number of units of the display devices and temporarily stores the data in the respective frame memories 16. The picture recording medium is reproduced by plural reproducing devices connected to respectively corresponding projectors. The projectors join the respective projected images by superposing these images two pixels each at both right and left ends. As a result, the large- screen display is realized without lowering the resolution.

Title: Method for printing surface of porous body
Inventor: TAGIWA IZUMI
IPC: B41M5/26
Filed: 1986-08-08
Abstract: PURPOSE:To apply printing to the surface of a porous body, by such a simple method that a pattern to be printed is formed on an almost colorless transparent heat-meltable film from a light absorbable coloring material and the film is closely adhered to the surface of the porous body such as a foam and the pattern is allowed to generate heat by the flash irradiation of the porous body on the film to be fusion-bonded to the surface of the porous body. CONSTITUTION:A line picture pattern 3 to be printed on a plastic foam 1 such as foamed styrol or polyurethane foam is formed on a heat-meltable base film 2 from light absorbable ink and the pattern forming surface of the film 2 is closely adhered to the foam 1. When the porous body is subjected to flash exposure on the film 2 using a flash lamp, the light absorbable ink forming the patter 3 absorbs light to allow the pattern 3 to generate heat and the base film of the heat generating part is melted to be fuse-bonded to the surface of the foam along with the ink. A non-pattern part holds a film shape and, when said part is removed as a unnecessary part, a desired pattern is left on the foam.
