  • Publication number: 20200174416
    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.

  • Publication number: 20200148497
    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: 10297496
    Abstract: In a method for processing a target object including a conductive layer and an insulating film formed on the conductive layer, the insulating film is etched by plasma treatment of a fluorine-containing gas to form an opening in the insulating film. A barrier film is formed to cover a surface of the insulating film and a surface of the conductive layer which is exposed through the opening formed in the insulating film. The target object having the barrier film is placed in an atmospheric environment, and the barrier film is removed from the target object by isotropically etching the barrier film. The target object is maintained in a depressurized environment from start of etching the insulating film to end of forming the barrier film. The barrier film is conformally formed on the surfaces of the insulating film and the conductive layer exposed through the opening formed in the insulating film.

  • Patent number: 9602690
    Abstract: The sheet discharge control unit notifies an engine control unit of plural conveyance interval times for different conveyance speeds beforehand, where each of the conveyance interval times corresponds to a period from completion of a post processing operation with respect to a preceding piece of recording material post-processed earlier until a start of a post processing operation with respect to a given piece of recording material post-processed subsequently to the preceding piece of recording material. When performing image formation on the given piece of recording material, the engine control unit selects a conveyance interval time which matches a conveyance speed for performing image formation on the given piece of recording material from the plural conveyance interval times, of which the engine control unit has been notified by the sheet discharge control unit, and determines a timing to start the image forming operation, based on the selected conveyance interval time.
