  • Publication number: 20240329552
    Abstract: An electrostatic image developing toner includes toner particles including a binder resin and vinyl resin particles. When a cross section of the toner particles is observed and the areas Sa [?m2] of Voronoi polygons obtained by Voronoi division of the cross section using geometric centers of the vinyl resin particles as generatrices are measured, Formulae (1) and (2) are satisfied: 0.03?Sac?0.20 (1), Ssd?0.10 (2), where Sac and Ssd represent the median [?m2] and the standard deviation [?m2] of the areas Sa of the Voronoi polygons, respectively.

  • Patent number: 12105470
    Abstract: A toner for developing an electrostatic charge image contains toner particles including first toner particles and second toner particles, the first toner particles having a brightness of less than 90 and the second toner particles having a brightness of 90 or more. The second toner particles constitute 0.1% by number or more and 10% by number or less of the toner particles, and, in the size distribution of the second toner particles, toner particles having a diameter equal to or smaller than the number-average diameter Dn of the toner particles constitute 70% by number or more.

  • Patent number: 11738697
    Abstract: A mounting part structure of an external detection sensor for a vehicle includes a sensor cover. A front portion of the sensor cover is locked to the sensor bracket via a front locking part that restricts displacement in a vertical direction of the vehicle when displacement of the sensor cover in forward and rearward directions of the vehicle and a vehicle width direction and rotation thereof around an axis following the vehicle width direction are allowed. A rear portion of the sensor cover is locked to the console bracket via a rear locking part that restricts displacement of the sensor cover in the vertical direction of the vehicle and the forward and rearward directions of the vehicle when displacement of the sensor cover in the vehicle width direction is allowed. The rear portion of the sensor cover is biased in the vehicle width direction by a rear spring part.

  • Patent number: 11345288
    Abstract: A display system comprises: a shooting unit configured to shoot a periphery of a vehicle; a display unit configured to display an image shot by the shooting unit; and a display control unit configured to switch a display mode of display in the display unit between a first display mode for displaying a first display region and a second display mode for displaying a second display region that is different from the first display region. When the display mode is switched to the second display mode in a state in which a display range of the display unit has been adjusted in the first display mode, the display control unit displays the second display region regardless of the adjustment of the display range.

  • Patent number: 9403423
    Abstract: A detachable-roof-equipped vehicle body structure includes a seal member provided in a roof opening section, and a soft top constructed to abut against the seal member. The seal member includes first and second seal units, and the soft top includes a flexible sheet for covering the roof opening section and a reinforcing member of higher rigidity than the sheet. The reinforcing member is abutted, from above, against both of the first and second seal units. The structure also includes a connecting bag part secured to the sheet, left and right side rails attached to the sheet, and a wire member inserted through the bag part and extending between the side rails. The wire member includes a small-diameter portion, and large-diameter portion each provided on a position spaced from a corresponding one of the side rails.

  • Publication number: 20050045740
    Abstract: A washer nozzle has nozzle outlets 7, 8 which are provided within fluid injecting openings in a nozzle main body for ejecting a washer fluid. The nozzle main body has extended portions which are provided at transverse end portions of the nozzle main body which are situated transversely outwardly of the fluid ejecting openings in such a manner as to extend transversely. The extended portions prevent an air flow from coming around the end portions of the nozzle main body to reach the fluid ejecting openings.
