  • Patent number: 11972270
    Abstract: A communication device may include: a memory configured to store management information in which, for each of a plurality of OIDs of a MIB, the OID and a setting value are associated with each other; and a controller, wherein the controller may be configured to: receive a setting command which conforms to TCP; write the setting value included in the setting command to the management information in association with the OID included in the setting command; and send a response command which conforms to the TCP. In a case where the setting command including a first OID and a first setting value is received, the controller may be configured to: write the first setting value to the management information in association with the first OID after the response command has been sent, and send the response command before the first setting value is written to the management information.

  • Patent number: 11781642
    Abstract: A power unit includes at least one drive source that outputs rotational power to a drive target other than pumps; a first pump rotationally driven by the rotational power of the drive source; a second pump rotationally driven by the rotational power of the drive source, the second pump being different form the first pump; and a power transmission structure that transmits the rotational power of the drive source to the first and second pumps. The power transmission structure includes transmission components and transmits the rotational power to the first pump through one of the transmission components and to the second pump through another of the transmission components.

  • Patent number: 11293547
    Abstract: A rotation position detection device includes a change drum, a magnetic field generator, and a magnetic field detector. The magnetic field generator is fixed to the change drum and rotates along with the change drum to differentiate an ambient magnetic field. The magnetic field detector is formed separately from the magnetic field generator and fixed to a position at which a magnetic field changes in response to rotation of the magnetic field generator so as to detect the magnetic field and output a signal that depends on the rotational position of the change drum on the basis of the detection result.
