Title: Method for coating solventless mastic adhesive
Inventor: NITTA MASAKI
IPC: B05D3/02
Filed: 1985-06-03
Abstract: PURPOSE:To provide resistance to showers by heating a high-viscosity solventless mastic adhesive to reduce the viscosity and coating the adhesive. CONSTITUTION:A high-viscosity solventless mastic adhesive having 7,000-8,000 poise viscosity at ordinary temp. is heated to 45-55 deg.C to reduce the viscosity to 2,500-5,000 poise and coated. The coated adhesive is then cooled and the viscosity is increased to the original viscosity. Accordingly, even when the adhesive subjected to 5kg/cm<2> shower pressure, the adhesive is never deformed and stripped off and the use of the solventless mastic adhesive is made possible. Consequently, since the adhesive contains no solvent, problems such as environment pollution and deterioration of working environment due to the volatilization of solvent are not caused.

Title: Picture processor
Inventor: ITO MINORU
IPC: G06T5/00
Filed: 1989-05-15
Abstract: PURPOSE:To quickly perform the picture processing by determining candidate values of rough adjustment like rotation or distortion and the binarization or multilevel conversion threshold level of the whole of an input picture in the large picture processing and determining rough adjustment like rotation or distortion and the threshold level in accordance with local picture characteristics in the small picture processing. CONSTITUTION:A device consists of a large picture processing circuit 3 and a small picture processing circuit 4. That is, the picture which is more efficiently processed in the large picture processing is processed by the large picture processing circuit 3, and the local picture which can be handled in the small picture processing is processed in the small picture processing circuit 4. Consequently, conventional trouble that the boundary processing is performed by overlapping picture boundary areas or the like at the time of arranging small picture is eliminated in the general processing to simplify the processing algorithm. The general processing is advantageous with respect to precision and efficiency at the time of detecting and correcting the rotation or the distortion, and the overhead for memory access is reduced in the local processing because of the use of a small memory space. Thus, the quick processing is possible.
