  • Patent number: 11664507
    Abstract: A manufacturing method for manufacturing a separator for a fuel cell includes a step of applying a laser beam to a surface of a plate-shaped metal plate having a rectangular shape such that an application range of the laser beam extends linearly. In the step, the laser beam is applied such that the application range includes a high-energy region in which energy to be given by the laser beam per unit distance in a direction where the application range extends linearly is high, and a low-energy region in which the energy is low. The high-energy region includes a first region, a second region, a third region, and a fourth region. The first region and the second region extend in parallel to one of long sides of the rectangular shape. The third region and the fourth region extend in parallel to the other one of the long sides.

  • Patent number: 11657634
    Abstract: A control system controls an operation mode of a mobile robot that autonomously moves in a predetermined area, and includes a feature detection unit, a classifying unit, and a system controller. The feature detection unit detects features of a person who is present in the vicinity of the mobile robot. The classifying unit classifies the person into a predetermined first group or a predetermined second group based on the features. The system controller selects a first operation mode when the person who belongs to the first group is present in the vicinity of the mobile robot and selects a second operation mode that is different from the first operation mode when the person who belongs to the first group is not present in the vicinity of the mobile robot, thereby controlling the mobile robot.
