  • Patent number: 8507170
    Abstract: An image-forming method includes forming an electrostatic image on an electrostatic image bearing member which has been charged; developing the electrostatic image to form a toner image; transferring the toner image on the electrostatic image bearing member with or without mediating an intermediate transferring member onto a transfer material; and fixing the toner image on the transfer material. The electrostatic image bearing member is a photosensitive member obtained by sequentially laminating a photoconductive layer and a surface layer formed of hydrogenated amorphous silicon carbide, and a sum of an atomic density of silicon atoms and an atomic density of carbon atoms in the surface layer of the photosensitive member is 6.60×1022 atoms/cm3 or more. The toner has a binder resin and magnetic iron oxide particles, and the magnetic iron oxide particles contain Fe(2+) at a content of 20.0 mass % or more and 25.0 mass % or less.

  • Publication number: 20130088748
    Abstract: An image forming apparatus includes an image data memory, a transmitting unit, a receiving unit, an edit information converting unit, and an image editing unit. The image data memory stores image data. The transmitting unit transmits related image data related to the image data to an external terminal apparatus. The receiving unit receives first edit information from the external terminal apparatus, the first edit information representing details of edit that has been performed on the related image data. The edit information converting unit converts the first edit information to generate second edit information, the second edit information representing details of edit that is to be performed on the image data. The image editing unit edits the image data by using the second edit information.

  • Patent number: 8413782
    Abstract: A clutch can comprise driving clutch plates spline-fitted on an input member, driven clutch plates arranged alternately with the driving clutch plates and spline-fitted on an output member, a clutch piston having one surface facing an oil pressure chamber and another surface facing the clutch plates and adapted to be displaced toward the plates by supplying oil to the oil pressure chamber and to be returned by discharging the oil from the chamber. A valve can pass through the clutch piston and be adapted to be closed for preventing oil from exiting the chamber to the other side of the clutch piston when the clutch is clutched-on and to be opened and allow airflow to the oil pressure chamber when the clutch is clutched-off. One or more weight reduction recesses can be formed on one surface of the clutch piston near the outer circumference further radially outward than the valve.

  • Publication number: 20130063759
    Abstract: A service providing apparatus includes the following elements. A communication unit communicates with an external terminal apparatus. An operation unit is used by a user for performing an operation. A notification unit notifies a user of information. A login controller receives a login request of a user from the operation unit or from an external terminal apparatus via the communication unit, and determines whether to permit the login. Upon receipt of a login request from a second user when a first user has already logged in, the login controller notifies the first user of occurrence of the login request via the communication unit or the notification unit, and permits the login of the second user in accordance with a notification received from the first user via the communication unit or an operation performed by the first user with the operation unit.

  • Patent number: 8011264
    Abstract: Revolving rollers, each provided on an outer peripheral surface thereof with revolving roller grooves extending therearound, are caused to mesh with a rack rod thread of a central rack rod with an axial angle over a lead angle of the rack rod thread and arranged for rotation on a holder member to be twisted. The holder member is rotated round the rack rod by a motor to translate the rack rod. A large thrust can be generated while ensuring a high reliability since a high efficiency is achieved by realizing rolling contact in set points of mesh of the rack rod thread and the revolving roller grooves, points of mesh are made planar, and interference in other points than the points of mesh can be suppressed. Also, play can be restricted by assembling the revolving rollers to the rack rod thread while applying torque in a direction, in which the axial angle is increased.

  • Patent number: 7116752
    Abstract: A region affected by X-ray beam limiting within a fluoroscopic image is specified based on position information on beam limiting by an X-ray beam limiting device. A judgment is made as to whether the region affected superposes a first brightness measuring region (region of interest) within the X-ray fluoroscopic image, and when superposition is not judged, automatic brightness control is performed based on the first brightness measuring region. When superposition is judged, the first brightness measuring region is transformed, and automatic brightness control is performed with reference to a second automatic brightness measuring region that does not superpose the region affected.
