  • Patent number: 6647788
    Abstract: An acceleration detecting device comprising a movable weight, a movable electric contact disposed on the weight, a fixed electric contact, an resilient member, and a friction creating mechanism. The movable electric contact slides on the fixed electric contact when a force is given to the weight for moving the weight in a first direction. The resilient member urges the weight continually in a second direction opposing to the first direction. The friction creating mechanism gives a frictional force to the weight when the weight travels a distance in excess of a certain amount in the first direction. The friction creating mechanism increases the frictional force as the weight continues to advance further in the first direction.

  • Patent number: 6553200
    Abstract: A liquid electrophotographic developing apparatus including a developing unit and a plurality of air transport members. The developing unit has an elongated opening disposed adjacent to a moving image-bearing surface of a photoreceptor, and it is used for converting an electrostatic latent image into a toner image. Electrodes formed within the elongated opening provide an electric field to charge toner particles in a liquid developer. The air transport members are provided around the elongated opening of the developing unit, and airflow therein has a predetermined air pressure to transport unused developer away from the image-bearing surface while permitting toner particles in the liquid developer deposited on the image-bearing surface to be retained by the image-bearing surface.

  • Patent number: 6191801
    Abstract: A color electrophotographic apparatus which can achieve full color image reproduction with one-pass developing is disclosed. According to the present invention, a flexible photoconductor is formed as an endless belt driven by a set of rollers. Developers of various colors are projected onto a surface of the photoconductor from a plurality of developing units. After the projection of the color developers is achieved, the resultant full color toner image is transferred to a recording medium. The toner image is then fused onto the recording medium, thereby reproducing the full color image. The flexible photoconductor is arranged to have a planar surface between the two rollers, with the four optical exposure units positioned to direct four parallel beams of light in a direction perpendicular to the planar printing surface of the photoconductor.

  • Patent number: 5765078
    Abstract: The image developing part 10 is constructed from the developing agent storing part 20 storing the fluid developing agent 18 and the developing agent supplying part 22 confronting the surface of the photosensitive drum 12 via the minute opening 25. The developing agent supplying part 22 includes a pair of, upper and lower, flat plates 24a and 24b which are placed in parallel and which define the uniform minute opening 25 over an entire width of the photosensitive drum 12. The flat plates 24a and 24b are formed with the electrodes 26a and 26b, respectively. It is possible to finely adjust the gap between the flat plates 24a and 24b through operating the minute displacement actuator 28 placed at the gap between the flat plates 24a and 24b. It is therefore possible to control the pressure to be exerted upon the fluid developing agent 18.
