Title: Method for repairing outer wall
Inventor: NAKAZAWA HARUMITSU
IPC: B05D3/12
Filed: 1989-06-17
Abstract: PURPOSE:To inexpensively repair an outer wall so as to be capable of easily applying re-painting by removing the existing scratch coat film on the surface of an existing outer wall by grinding and subsequently applying a raw material becoming a release layer to the ground surface in a liquid form to cure the same in a film state and applying topcoating having an arbitrary color thereon. CONSTITUTION:The surface of the outer wall composed of, for example, ALC, concrete or mortar scratch coat of an existing building is ground to remove a decorative film or scratch coat to flatten the surface of the outer wall. Subsequently, a grinding powder is removed from the surface of the outer wall and a synthetic resin raw material becoming a release layer is applied to the outer wall in a liquid form and cured to form a film. At this time, this release layer releasable in the future also functioning as a substrate layer is applied so as to coat the entire outer wall inclusive of joints. Next, topcoating is applied to this release layer to form a novel paint film. By performing this repairing, re-painting can be performed inexpensively in an extremely easy manner and aesthetic properties, waterproofness and execution properties are improved to a large extent.

Abstract: PURPOSE:To provide an animation image coding device which is used for various communication equipment, information equipment and AV equipment and can secure the excellent image quality by eliminating the deterioration of the reproduced image quality due to the conspicuous distortions of pixel blocks caused by a highly efficient coding operation with addition of the simple hardware. CONSTITUTION:An A/D converter 11 quantizes the analog animation image signals and stores these quantized signals in an image memory 13 as the image data. An address generator 15 generates by changing the initial value of the start for extraction of the pixel block at every image plane. A pixel block extractor 14 reads the pixel block out of an image memory 13 with the extraction start pixel defined as a start point and transfers the pixel block to a high efficient coder 16. Thus the block distortions can be reduced that are caused by the compression of data with a highly efficient coding operation since the block distortion positions are changed at every image plane in an animation image reproduction mode.
