  • Publication number: 20240338285
    Abstract: A control device according to an embodiment includes a first region including a CPU and a sequence signal generation circuit; and a second region including an abnormality detection circuit, a sequence signal detection circuit, a first register storing multiple methods of recovery from occurrence of abnormality, and a second register for use to select one method of recovery from the multiple methods of recovery, the second region being higher in reliability than the first region. The sequence signal generation circuit converts a first signal that specifies the one method of recovery into a sequence signal containing a second signal, which is a digital signal of a predetermined pattern, and the sequence signal detection circuit changes a set value of the second register upon receiving the second signal.

  • Patent number: 11548063
    Abstract: An insert (cover member) is formed of an iron-based alloy. A casting mold is constituted by a fixed mold and a movable mold. An insert housing portion (cover housing portion) for housing the insert is formed in a separation surface between the fixed mold and the movable mold, and a magnet is embedded in the insert housing portion of either the fixed mold or the movable mold. A robot grips the insert with a gripping portion (hand) to convey the insert to a position facing the insert housing portion, releases the insert at the facing position in a state where a predetermined clearance is secured between the insert and the insert housing portion, and causes the insert to be attracted to the insert housing portion by the magnet.
