    • A operation program of a robot is simply changed by using a workpiece body without using a master body. The operation program of the robot is corrected by correction data obtained from cameras. When a point of the operation program is desired to be changed to another point, a point on the workpiece body is changed to a changed point. A robot control unit reads the changed point as the coordinate values of the respective axes and changes the same to space coordinate values. Further, the space coordinate values are converted to reference space coordinate values on the master body by an inverse conversion matrix of the correction data. The reference space coordinate values are inversely converted to the coordinate values of respective reference axes. Since the operation program is commanded by the coordinate values of the respective reference axes, the point of the operation program is converted to the another point by using the coordinate values of the respective reference axes. With this method, the operation program can be simply changed without using the master body.

    • Copolymerization is started by reacts in and acrylamide represented by the general formula ##STR1## wherein R.sub.1 represents a hydrogen atom or a methyl group and R.sub.2 represents a hydrogen atom, an alkyl group, an aryl group or an aralkyl group, with an amount of methyl methacrylate in pure methanol or methanol containing Water in an amount of not more than 30% by weight based on the total weight of methanol and water, and, an additional amount of the methyl methacrylate is added at periods during proceeding of the polymerization. The obtained copolymer is heated at 80.degree. to 150.degree. C. in the same solvent and in the presence of an alkaline catalyst, to an imidized acrylic resin containing glutarimide groups.The imidized acrylic resins obtained by the process of the present invention have excellent thermal stability, transparency and color shade, and contain little acid or acid anhydride.Where the glutarimide group is N-hydrogenglutarimide, the imidized acrylic resin is readily isolated as a particulate solid of stabilized emulsion by addition of a hydroxide and/or alcolate of an alkali metal to a solution of the imidized acrylic resin in water-containing methanol, followed by cooling. This emulsion is neutralized with an acid, separated by filtration and washed, to give a highquality imidized acrylic resin.
    • 通过与由通式“IMAGE”表示的丙烯酰胺进行共聚,其中R1表示氢原子或甲基,R2表示氢原子,烷基,芳基或芳烷基, 甲基丙烯酸酯在纯甲醇或含甲醇的水中的用量不超过30重量%,基于甲醇和水的总重量,并且在聚合过程中加入额外量的甲基丙烯酸甲酯。 将得到的共聚物在相同的溶剂中,在碱性催化剂的存在下,在80〜150℃下加热至含有戊二酰亚胺基团的酰亚胺化丙烯酸树脂。 通过本发明的方法获得的酰亚胺化丙烯酸树脂具有优异的热稳定性,透明度和色调,并且几乎不含酸或酸酐。 当戊二酰亚胺基为N-羟基胆碱酰亚胺时,酰亚胺化的丙烯酸树脂通过将碱金属的氢氧化物和/或醇酸盐添加到酰亚胺化的丙烯酸树脂在含水甲醇的溶液中而容易地分离为稳定的乳液的颗粒状固体, 随后冷却。 将该乳液用酸中和,通过过滤分离并洗涤,得到高质量的酰亚胺化丙烯酸树脂。
