  • Patent number: 11523019
    Abstract: In a printing system capable of supplying a sheet of a job having undergone print processing by the printing unit of a printing apparatus to a post-processing unit capable of executing at least a specific type of post-processing among a plurality of types of post-processes, when the target job requires the specific type of post-processing, the printing apparatus is inhibited from executing print processing of the job without explicitly determining a sheet necessary for the print processing of the job by a user using a user interface unit. When the target job does not require the specific type of post-processing, the printing apparatus is permitted to execute print processing of the job without explicitly determining a sheet necessary for the print processing of the job by the user using the user interface unit.

  • Patent number: 11462350
    Abstract: A coil component includes a winding core, and a first wire and a second wire that are spirally wound around the winding core, that have substantially the same number of turns, that are not electrically connected to each other, and that have a twisted portion at which the first wire and the second wire are twisted together. In the coil component, the first wire and the second wire are wound around the winding core such that layers are formed. The twist pitch of the twisted portion at a turn in a first layer differs from the twist pitch of the twisted portion at a turn adjacent thereto in a second layer.
