  • Publication number: 20240146055
    Abstract: Because power receiving and distributing equipment is configured with a plurality of devices combined together, it is sometimes difficult to perform inspection operation for the inspection items separated into those set for each individual device. Therefore, in the power receiving and distributing equipment, even if an attempt is made to associate each device with an inspection result, an inspection result of a plurality of devices that are grouped cannot be associated with each device. According to the present disclosure, an inspection result of the power receiving and distributing equipment can be associated with an inspection item of each device.

  • Publication number: 20240103414
    Abstract: A fixing unit or device that can be used in an image forming apparatus includes a first heater element that is formed of a material that increases in electrical resistance with increases in temperature. A controller of the fixing unit is configured to vary a duty ratio of electric power applied to the first heater element during a start-up operation in which the temperature of the first heater element is raised to a target operating temperature. By varying the duty ratio during the start-up operation, changes in the resistance of the first heater element with the heating can be compensated. For example, the duty ratio can be increased during the course of the start-up to achieve the target operating temperature faster.
