  • Publication number: 20080240792
    Abstract: A developing device capable of preventing deterioration of the image quality, which is caused when a developer recovered by a developing roller re-adheres thereto, and an image forming apparatus equipped with the developing device. The developer conveyance amount on the upstream side of an agitation conveyance path in a developer conveyance direction becomes larger than the amount of developer to be transported from a recovery conveyance path to the agitation conveyance path, by making the developer conveyance amount on the upstream side of an agitating screw in the developer conveyance direction equal to or larger than the developer conveyance amount on the downstream side of a recovery screw in the developer conveyance direction. Accordingly, the amount of developer existing on the upstream side of the agitation conveyance path in the developer conveyance direction becomes small, whereby the developer can be delivered smoothly from the recovery conveyance path to the agitation conveyance path.

  • Publication number: 20080220924
    Abstract: A vehicle planetary gear device includes a ring gear, a sun gear, and a carrier, and pinions housed in the carrier. A penetration hole formed in a hollow cylindrical portion of the carrier has two inner wall surfaces that face an outer peripheral surface of a pinion. One of the inner wall surfaces has a curvature radius larger than the radius of the pinion, and has a curvature center that is apart from the radius center of the pinion gear. The pinion is disposed with respect to the carrier with a predetermined space formed between the one of the inner wall surfaces and the outer peripheral surface of the pinion, and thereby slides along a radial direction of the carrier.

  • Patent number: 7418473
    Abstract: All port numbers are set at a server, whereas only one port number is set at a client. The client searches for the server by using the set port number. The server responds to searching by the client and notifies the client of the other port number that is not set at the client. The client establishes the communication with the server by using the notified port number. This makes it unnecessary to set all port numbers at the client. It is therefore possible to provide a server client system with time for setting a port number decreased.

  • Publication number: 20080181670
    Abstract: A developing device which can stably supply a developer to a latent image carrier by preventing the scattered developer from being discharged and thereby preventing the developer from being discharged despite that the amount of developer within the developing device does not increase, and an image forming apparatus using the developing device. A block member serving as a scattered developer discharge prevention member is provided so as to block a path through which the developer scattered as a result of a conveyance operation of a supply screw serving as a developer conveying member moves toward a developer discharge port. Accordingly, the scattered developer is prevented from reaching the developer discharge port and being discharged therefrom.

  • Publication number: 20080136349
    Abstract: In a discharge lamp apparatus for lighting a discharge lamp, a ballast is disposed outside of a lamp housing of a discharge lamp and is electrically connected to the discharge lamp through a connector. A ballast housing of the ballast is connected to a bottom wall of the lamp housing. In the ballast housing, a ballast circuit board is arranged along a top wall of the ballast housing that is opposed to the lamp housing. Accordingly, it is less likely that the ballast circuit board will be wetted by condensation or water vapor entered the ballast housing. Additionally, a partition wall can be provided in the ballast housing between the connector and the ballast circuit board to block the condensation or water vapor from flowing toward the ballast circuit board.
