  • Patent number: 10346202
    Abstract: A task circumstance processing system includes a processor that executes a process. The process includes: referencing a recognition information stored in a memory, the recognition information stores, for each of plural task processes in task definitions defining relationships between the plural task processes, recognition information for recognizing execution of each of the plural task processes, and extracting for each of the task processes a timing where the recognition information is expressed in observation data from observing circumstances of the task; and outputting a result of comparing a relationship between plural task processes that have been executed as identified by the extracted timings, against a relationship between plural task processes defined by the task definitions stored in the memory.

  • Patent number: 8915666
    Abstract: A taper coupling structure includes a groove, serving as a hollowed part, provided in a rear end surface of a hub. The groove is formed continuously in the circumferential direction and uniformly in the radial direction. In the state in which a taper shaft is fitted in the hub, the groove interferes with the taper shaft in the radial direction. An inner shell part, which is a portion on the inside of the groove in the radial direction, has a low radial rigidity because of the presence of the groove. For this reason, if a force is applied from the hollow portion of a flange part toward the outside in the radial direction, the diameter of the inner shell part is liable to be increased in the radial direction by elastic displacement (deflection).

  • Publication number: 20120093579
    Abstract: There is provided a taper coupling structure in which a taper shaft can easily be fitted in and removed from a hub. In a taper coupling structure 10, a groove 34 serving as a hollowed part is provided in a rear end surface HB of a hub 30. The groove 34 is formed continuously in the circumferential direction and uniformly in the radial direction. In the state in which the taper shaft 20 is fitted in the hub 30, the groove 34 interferes with the taper shaft 20 in the radial direction. An inner shell part 35, which is a portion on the inside of the groove 34 in the radial direction, has a low radial rigidity because of the presence of the groove 34. For this reason, if a force is applied from the hollow portion of a flange part 32 toward the outside in the radial direction, the diameter of the inner shell part 35 is liable to be increased in the radial direction by elastic displacement (deflection).

  • Patent number: 8153941
    Abstract: A first plate material is set on a work stage. The first plate material includes first components commonly connected to a first connection member. A second plate material is subsequently set on the work stage. The second plate material includes second components commonly connected to a second connection member. The second components are superposed on the corresponding first components. The first components as well as the second components can be handled as a one-piece component. It leads to an improved productivity. Heat surfaces of a heat block contact the second components. The connection members are prevented from thermal expansion. The constant intervals are reliably maintained between the adjacent first components and the adjacent second components.

  • Patent number: 7133733
    Abstract: The present invention relates to a design support system constructed so as to comprise a manufacturing line information preparation section and an output section. On the basis of element types selected by a selection section as arbitrary element types to be used for constituting a manufacturing line, the manufacturing line information preparation section prepares information about the manufacturing line by means of acquiring information about element types stored in an element type database beforehand. The output section can output the information about the manufacturing line prepared by the manufacturing line information preparation section. A manufacturing line including a plurality of steps is efficiently examined, determined, and established, thereby shortening the time required to design and manufacture the manufacturing line and curtailing manufacturing costs.
