  • Publication number: 20240359102
    Abstract: For at least one floating object disposed in the air, of dynamic objects disposed in a virtual space, movements of the dynamic objects being controlled based on physical calculation, a load applied to the floating object is calculated based on a game process. In a first case in which the load does not exceed a first limit load in a first direction including at least a downward direction in the virtual space, a first force that maintains a position of the floating object in the virtual space, is additionally applied to the floating object. In a second case in which the load exceeds the first limit load in the first direction, the first force is removed. The position and an orientation of the floating object are updated based on the physical calculation.

  • Patent number: 12124183
    Abstract: An image forming apparatus includes a photosensitive member, a charging member, an electrostatic image forming portion, a developing member, a transfer member, a transfer voltage source, a brush member, a brush voltage source, and a controller capable of executing a cleaning operation. The controller carries out control so that the cleaning operation includes a first operation in which a potential difference is formed between the transfer member and the photosensitive member so that toner charged to a normal charge polarity is moved from the transfer member toward the photosensitive member, and a second operation in which a potential difference is formed between the brush member and the photosensitive member so that the toner charged to the normal charge polarity is moved from the photosensitive member toward the brush member.

  • Publication number: 20240302785
    Abstract: An image forming apparatus including an image bearing member, a charging member, a developing roller, a transfer roller, and a brush configured to be brought into contact with a surface of the image bearing member on a side downstream of a transfer portion and upstream of a charging portion in a rotation direction of the image bearing member and in which, wherein, after the transfer of a developer image onto a transferred member, a developer remaining on the surface of the image bearing member is collected by the developing roller, the brush is disposed such that, in a cross section perpendicular to a rotation axis of the image bearing member, a contact region of the surface of the image bearing member in contact with the brush overlaps a virtual line containing the rotation axis of the image bearing member and extending upward from the rotation axis in a vertical direction.

  • Patent number: 12072654
    Abstract: A control unit performs control to make a direction of an electric field generated in a first area of an image carrier forming a transfer portion during image forming operation, relative to a voltage applied to a brush member in a state where the first area passes through a contact portion, different from a direction of an electric field generated in a second area of the image carrier forming the contact portion, relative to the voltage applied to the brush member during a period when operation is shifted from first operation in which the image carrier is rotated at a first speed to second operation in which the image carrier is rotated at a second speed different from the first speed, during non-image forming operation different from the image forming operation.

  • Patent number: 9666361
    Abstract: A method for producing a bonded rare-earth magnet according to an embodiment of the present invention includes the steps of: providing a rapidly solidified rare-earth magnet alloy powder; providing a solution in which a resin that is in solid phase at an ordinary temperature is dissolved in an organic solvent; mulling the rapidly solidified rare-earth magnet alloy powder and the solution together and vaporizing the organic solvent, thereby making a bonded rare-earth magnet compound in which magnet powder particles that form the rapidly solidified rare-earth magnet alloy powder are coated with the resin; making a compressed compact by compressing the bonded rare-earth magnet compound under a pressure of 1000 MPa to 2500 MPa; and thermally treating the compressed compact. If the rapidly solidified rare-earth magnet alloy powder to be mulled is 100 mass %, the solution includes 0.4 mass % to 1.0 mass % of the resin and 1.2 mass % to 20 mass % of the organic solvent.
