  • Patent number: 11161247
    Abstract: An operation instruction list including starting points and ending points of trajectories of a plurality of robot arms is generated (a trajectory definition data generation process). Order of generation of trajectories is determined in accordance with the operation instruction list (a generation order determination process). A trajectory of a specific robot arm included in the operation instruction list is generated in accordance with a starting point and an ending point such that the trajectory avoids obstacle spaces registered in the obstacle memory when trajectories of other robot arms are generated (a trajectory generation process). A sweeping space in which a structure of the arm sweeps when the robot arm is operated along the generated trajectory is added to the obstacle memory as an obstacle space to be avoided by the other robot arm (an obstacle registration process).

  • Patent number: 10919153
    Abstract: A teaching system, includes a computer configured to calculate trajectories of a plurality of robots disposed so as to have a common working area on a virtual space and a display unit. The computer calculates a robot passing area which is a set of trajectories drawn by a point constituting each robot when a driving unit of each robot is operated based on a teaching value on the virtual space for each robot. The computer detects whether the robot passing areas of the robots cross with each other. The computer sets a constraint condition by which none of the plurality of robots is permitted to pass through at least to a partial space within a crossing area in a case where the computer detects that the robot passing areas cross with each other.

  • Patent number: 5407990
    Abstract: A composition for forming insulating films on electrical steel sheets includes a (meth)acrylate ester polymer, modified into a polymer containing an ethylenic unsaturated carboxylic acid component as an essential copolymerizable component, optionally with other copolymerizable vinylic compound components. The composition is used in the form of an aqueous emulsion with or without methacrylate ester base polymer powders. The composition has low expandability and coatability and provides an improved film. Especially when the composition contains methacrylate ester base polymer powders, improved weldability is achieved and high-quality coated steel sheet products are provided. A method of forming the insulating films is also described.

  • Patent number: 4844753
    Abstract: The present invention relates to a method for forming insulating films on electromagnetic steel plates.Conventional films obtained by coating only an inorganic component such as a chromate, forming an organic-component film on an inorganic-component film or coating a mixture of both components individually have had disadvantages such as the occurrence of crateriform pinholes, reductions in punching properties, rises in the cost and decreases in interlayer resistance and the like.The present invention provides a method wherein a composition obtained by combining an acrylic resin and/or an acryl-styrene resin and guanamine resin as the organic components with an inorganic substance composed mainly of a chromate is coated and dried on an electromagnetic steel plate to form thereon an insulating film.According to the present invention, it is possible to form an insulating film which has excellent film properties and is free from said disadvantages.
