Patent number: 6647788Abstract: 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.Type: GrantFiled: July 20, 2001Date of Patent: November 18, 2003Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Eiichiro Murai, Tohru Matsumoto, Yuji Hiraoka

Patent number: 6191801Abstract: 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.Type: GrantFiled: July 3, 1997Date of Patent: February 20, 2001Assignee: Aetas Peripheral CorporationInventors: Yuji Hiraoka, Bobo Wang

Patent number: 5765078Abstract: 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.Type: GrantFiled: August 7, 1996Date of Patent: June 9, 1998Assignee: Brother Kogyo Kabushiki KaishaInventors: Takemi Yamamoto, Yuji Hiraoka
