The viscosity of the magnetic paint obtd. by mixing the same with the magnetic powder increases and a large amt. of a solvent is required to maintain the adequate viscosity in the stage of coating when the content exceeds 90wt%. The strength of the coated film deteriorates if the content is below 50wt%. The adequate content of the vinylidene chloride is 0.1-25wt% of the content of the copolymer and the heat resistance deteriorates when the content exceeds 25wt%. The adequate content of the vinyl ester of carboxylic acid is 0.1-20wt% of the content of the copolymer and the dispersibility deteriorates when the content exceeds 20wt%. The adequate content of the hydroxyalkyl acrylate is 0.1-30wt% of the content of the copolymer and the solubility with solvents deteriorates when the content exceeds 30wt%. The adequate content of the copolymerizable vinyl-contg. phosphoric acid is 0.1-10wt% of the content of the copolymer and the solubility with solvents deteriorates when the content exceeds 10wt%.

IPC: G06F1/28
Filed: 1994-06-30
Abstract: PURPOSE:To attain a highly reliable system by removing fuzziness in the ON/ OFF of a power supply for a system having an automatic operation controller. CONSTITUTION:An automatic operation control part 1-d is provided with a system power supply monitoring circuit 2-b to monitor the existence of power supply to a system control part 1-g.
