  • Patent number: 7974563
    Abstract: A pressure member contacts a heating member to form a nip part where a recording material is heated and pinched-conveyed, and includes a first elastic layer and a second elastic layer 24b having a higher thermal conductivity than that of the first elastic layer. An elastic layer is formed of a combination of the first elastic layer and the second elastic layer so that the thickness of the second elastic layer at the end portion is thicker than the thickness of the second elastic layer at the center portion in a longitudinal direction perpendicular to a recording material conveyance direction. Accordingly, when using the pressure member to contact the heating member to form the nip part, it is possible to reduce the difference between a center nip width and an end-portion nip width of the nip part.

  • Patent number: 7762643
    Abstract: In an image forming method employing an inkjet technique, when a dot is formed by the use of a normal nozzle and an abnormal nozzle neighboring to the abnormal nozzle, binary data are corrected so as not to form the dot by the use of the abnormal nozzle and the binary data are also corrected so as to form a compensation dot, which has a color different from a color used by the abnormal nozzle, in the vicinity of a dot forming position by the abnormal nozzle. Thereby, the white stripe and the deep-colored stripe generated due to the flight bending phenomenon are almost invisible.

    Abstract: A method of producing a laminated body having a ceramic porous body having a thickness of 300 ?m or larger and a ceramic dense body having a thickness of 25 ?m or smaller. A green body for the porous body and a green body for the dense body are laminated to obtain a laminate, which is then subjected to pressure molding by cold isostatic pressing to obtain a pressure molded body. The pressure molded body is sintered to obtain a laminated sintered body. By reducing the leakage rate of helium gas of the laminated sintered body to 10?6 Pa˜m3/s or lower, the operational efficiency of the cell can be improved, and the deterioration of the cell can be prevented to improve an output after the cell is subjected to initiation and termination cycle tests of operation.
