  • Patent number: 11721595
    Abstract: A method of processing an object using a plasma processing apparatus is provided. The plasma processing apparatus includes a stage on which the object is placed in a chamber, an outer peripheral member disposed around the stage, and a first power supply configured to apply voltage to the outer peripheral member. The method includes a step of exposing the object to a plasma containing a precursor having a deposition property, while applying voltage from the first power supply to the outer peripheral member. In applying voltage to the outer peripheral member, a status of a deposition film containing carbon that is deposited on the outer peripheral member is monitored, and the voltage applied to the outer peripheral member is controlled based on the monitored status of the deposition film.

  • Publication number: 20230183035
    Abstract: An image forming system includes a detection unit to detect a recording material, having an image formed thereon by an image forming unit, placed on a processing tray, a staple unit, a discharge unit, and a discharge tray. A first mode of the system is to discharge the recording material conveyed from the image forming unit to the discharge tray via the processing tray and a second mode involves waiting for instruction for executing. When the detection unit detects the recording material inserted into the processing tray in the second mode, and a recording material first mode conveying instruction is issued in a state of waiting for the executing instruction after the recording material detection, a discharge operation is performed to discharge the recording material inserted into the processing tray to the discharge tray without the staple unit executing staple processing on the recording material inserted into the processing tray.

  • Patent number: 11163254
    Abstract: An image forming system includes a processing tray, a detecting unit, a stapling unit, a discharge tray, an instruction unit, and a control unit. Recording material, placed on the processing tray, is detected by the detecting unit. When instructed, the stapling unit can staple the detected recording material. Stapled recording material then is discharged to the discharge tray. The control unit controls switching between a first mode wherein a stapling process is executed and a second mode where the stapling unit executes the stapling process after the detecting unit detects recording material inserted into the processing tray and the execution instruction are received. If an instruction to interrupt a power supply of the image forming system is received in the second mode, the control unit causes recording material inserted into the processing tray to discharge to the discharge tray and then interrupts the power supply without the stapling process executing.
