  • Patent number: 12066767
    Abstract: An image forming apparatus includes an image bearing member and a developer bearing member. A first period is from when rotational drive of the developer bearing member is started until increased to a speed at which the image forming apparatus performs image forming. A first absolute value of a difference between a developer bearing member surface potential Vdc and an image bearing member surface potential Vd, as determined when the image bearing member is facing the developer bearing member, is obtained during the first period. The value |Vdc?Vd| obtained during the first period is smaller than the value |Vdc?Vd| obtained after the first period. During the first period, the image bearing member surface potential Vd at the facing position is a first potential and, after the first period, the image bearing member surface potential Vd at the facing position becomes a second potential different from the first potential.

  • Publication number: 20240259825
    Abstract: Provided is a radio communication device capable of reducing interference, caused by non-SR transmission, with a basic service set (BSS) performing spatial reuse (SR) transmission. An SR transmission resource control unit (107) of the radio communication device (SR initiator) (100) determines transmission resources for an SR signal to be transmitted by means of SR to a second BSS other than a first BSS to which the radio communication device (100) belongs on the basis of radio quality information transmitted from other radio communication devices (SR responders) in the first BSS. A radio transmission/reception unit (101) transmits the SR signal by using the determined transmission resources.

  • Patent number: 12052769
    Abstract: A communication apparatus in the present disclosure comprises an AID generator, a Trigger frame generator, and a wireless transmitter/receiver. When a Trigger Type in a trigger frame is an RA trigger, the AID generator generates, as information for an AID12 subfield, information that is different from an AID. The Trigger frame generator generates a RA variant Trigger frame when the Trigger Type in the trigger frame is an RA trigger, and sets, in the AID12 subfield included in the RA variant Trigger frame, the information output from the AID generator. The wireless transmitter/receiver transmits the Trigger frame, generated by the Trigger frame generator, to a terminal.

  • Publication number: 20240190021
    Abstract: A gripping device includes a partition film that is elastically deformable, a vacuum pump (deformation unit) that elastically deforms the partition film, and a cylindrical gripping portion that extends from the peripheral edge of the partition film and is elastically deformed in the central axis direction along with the elastic deformation of the partition film to wrap a workpiece. When the gripping portion comes into contact with the workpiece, a sealed space is formed between the workpiece, the gripping portion, and the partition film. Since the volume of the sealed space increases due to the elastic deformation of the partition film, a negative pressure is generated in the sealed space. The gripping device reliably grips the workpiece by a frictional force acting between the workpiece and the gripping portion and a suction force due to a negative pressure generated in the sealed space.
