  • Patent number: 10908525
    Abstract: A bearing component for rotatably receiving a rotating shaft on an end of a rotating unit includes a component body, an inner protrusion, and one or more outer protrusions. The component body has a recess into which the rotating shaft is rotatably inserted. The inner protrusion protrudes from a wall portion of the recess facing an end surface of the rotating shaft. The inner protrusion receives an axial load by the rotating shaft. The outer protrusions protrude from an outer surface of the component body opposite to the recess. The one or more outer protrusions are in contact with a holding unit. A contact portion between the outer protrusions and the holding unit is offset from a contact portion position between the inner protrusion and the end surface. The contact portion between at least one of the outer protrusions and the holding unit has a non-planar shape.

  • Patent number: 10605896
    Abstract: A first data group, which indicates reflection wave intensities from reflection points for radar directions indicating directions in which the corresponding reflection points exist relative to a radar apparatus and distances from the radar apparatus to the reflection points, and a second data group, which indicates Doppler velocities of the reflection points for the radar directions and the distances from the radar apparatus to the reflection points, are used to generate a third data group, which indicates the reflection wave intensities of the reflection points. A radar moving direction relative to a moving direction of the vehicle for each frame is generated based on the third data group. The radar moving direction when the moving direction of the vehicle is straight ahead is estimated using the radar moving direction in a predetermined number of frames, and the radar installation angle is calculated using the estimated radar moving direction.

  • Patent number: 10564581
    Abstract: An image forming apparatus includes a photoreceptor, a charging unit, an exposure unit, a developing unit, a transfer unit, a detector, and a controller. The charging unit charges the photoreceptor. The exposure unit exposes the photoreceptor charged by the charging unit to light and forms an electrostatic latent image on the photoreceptor. The developing unit develops the electrostatic latent image that has been exposed by the exposure unit and formed on the photoreceptor. The transfer unit transfers an image obtained by development by the developing unit to a transfer object. The detector detects strip developer, which is a strip-shaped developer image formed on the transfer object.

The image processing unit includes: a charging unit that is provided to face an image carrier and applies a direct current voltage on which an alternating voltage of a first frequency is superimposed to charge the image carrier; an electrostatic latent image forming unit that forms an electrostatic latent image on the charged image carrier with light scanning based on image information; a developing unit that develops the electrostatic latent image; and a transfer unit that transfers the developed image to a recording medium. When an image density based on the image information is greater than or equal to a specific image density, the switching unit switches a frequency of the alternating voltage at least during charging performed by the charging unit to a second frequency different from the first frequency.

  • Patent number: 9720344
    Abstract: An image forming apparatus includes a charger, a charge eliminator, and a controller. The charger charges a surface of an image carrier. The charge eliminator eliminates residual charge from the surface of the image carrier charged by the charger. The controller performs control to reduce a level of charge elimination performed by the charge eliminator during a third period compared to a level of charge elimination performed by the charge eliminator during a second period in which an image for determining an image-forming condition is formed. The third period is a period other than the second period within a first period that is a period, other than a period of normal image formation, during which the surface of the image carrier is charged by the charger.

    Abstract: An image forming apparatus includes image forming devices which each forms a developer image on a latent image carrier, transfers the developer image onto an intermediate transfer member, and cleans the latent image carrier by using a plate-shaped cleaning member, the intermediate transfer body, and a controller. The developer used in one of the image forming devices is a low-electrostatic-propensity developer having an electrification performance lower than those of the developers used in the other image forming devices. The controller has a control mode for executing a supply operation in which the low-electrostatic-propensity developer used in the one of the image forming devices is transferred onto the intermediate transfer body and at least a part of the low-electrostatic-propensity developer is reversely transferred onto the latent image carriers of the other image forming devices and caused to reach the respective plate-shaped cleaning members.
