Title: Developing roller, developing device, process cartridge and image forming apparatus
Inventor: HATTORI YOSHIO
IPC: G03G15/08
Filed: 2006-07-03
Abstract: <P>PROBLEM TO BE SOLVED: To provide a developing roller capable of restraining the deviation of pumping-up amount and achieving high image quality, a developing device, a process cartridge and an image forming apparatus.  <P>SOLUTION: The developing roller 16 is arranged nearly on the left side with respect to a photoreceptor drum 1, and a developing doctor 17 is arranged nearly on the downside of the developing roller 16. The flux distribution of a magnet roller 32 is shown by an alternate long and short dash line, and the deviation is caused in a distance between the magnet roller 32 and a developing sleeve 31 because of the gravity 50 of the magnet roller 32 and force 51 generated when developer is regulated by the developing doctor 17. Therefore, magnetic flux 40 on the developing sleeve 31 near the developing doctor 17 becomes larger at a center part than at both ends in a longitudinal direction of the developing roller 16 and the pumping-up amount at the center part is larger than that at both ends. In order to eliminate such a phenomenon, the deviation is previously given to one magnetic pole (magnetic pole to perform pumping-up) of the magnet roller 32, whereby flux density on the developing sleeve 32 is lowered and the deviation of the pumping-up amount is restrained.  <P>COPYRIGHT: (C)2007,JPO&INPIT

Filed: 2006-07-25
Abstract: <P>PROBLEM TO BE SOLVED: To effectively exhibit the capability of exhaust gas purification, by properly controlling OSC conditions of each of catalysts in response to operating conditions of an internal combustion engine.  <P>SOLUTION: The internal combustion engine has a plurality of cylinder groups (banks) such as a V-type internal combustion engine, and each cylinder group has an independent exhaust gas passage. A first catalyst is arranged on each exhaust gas passage, and a common exhaust gas passage is formed so that each exhaust gas passage is merged at its downstream. A second catalyst is arranged on the common exhaust gas passage. When control of the engine is changed from each cylinder-group control to the stoichiometric control, an air-fuel ratio control section sets up a group of cylinders established to be rich combustion state by each cylinder-group control to a lean combustion state during a designated period, and sets up a group of cylinders established to be lean combustion state by each cylinder-group control to a rich combustion state during the designated period. Thus, an amount of oxygen occlusion (OSC) of the first catalyst corresponding to each cylinder-group is shifted to a neutral condition (for example, at the condition of OSC of approximately 50%) in which the purification function of the catalyst can be maximized.  <P>COPYRIGHT: (C)2008,JPO&INPIT
