  • Stator core element, production apparatus, and production method
    Publication number: 20090127970
    Abstract: A stator core is composed of two compacts of compressed powder magnetic cores joined in the axial direction. A yoke portion includes projections projecting axially outward from end surfaces in the axial direction of a tooth. The length in the axial direction of the tooth is gradually reduced radially toward the outside of the stator core, and the length in the circumferential direction of the tooth is gradually increased radially toward the outside of the stator core. A molding is formed by pressing magnetic powder placed in a die by a single punch placed on one side in the axial direction and two punches placed parallel to each other on the other side in the axial direction. The stator core for a rotary electric machine is thus produced.

  • FIXING DEVICE AND IMAGE FORMING DEVICE USING THIS
    Publication number: 20090123170
    Abstract: When the rotational speed of rotatable heating means for thermally fixing an image on a recording paper is changed from a first rotational speed of the highest level to a second rotational speed of the lowest level by changing the operation mode of a fixing device, the direct change from the first rotational speed to the second one may increase the overshoot of the temperature of the heating means. This shortens the life of the belt and causes an error of abnormally high temperature. To avoid an excessive overshoot of the temperature of the heating means, after the heating means is rotated for a predetermined time at a third rotational speed between the first and second rotational speeds, the rotational speed is changed to the second one.

  • Fixing device and temperature control method
    Patent number: 7388595
    Abstract: As a cooling mechanism that cools the entire paper passage area of a heat-producing belt, a rotational drive method of the heat-producing belt is employed and the heat-producing belt is cooled by rotational cooling by being made to idle when paper is not being passed through. An excitation apparatus and the above-described cooling mechanism are controlled so that recording paper is not passed through and the heat-producing belt is cooled while being heated over the heating width when the small-size recording paper is passed through until the temperature detected by a paper non-passage area temperature detecting sensor is at or below a predetermined fixing temperature. This fixing apparatus enables an excessive rise in temperature of a paper non-passage area of the heat-producing belt to be efficiently eliminated, and the temperature distribution of heat-producing belt to be made uniform in a short time.
