    • Apparatus for fixing toner image on a toner image supporting member in electrophotographic copying machine is disclosed. The fixing apparatus includes three rotary rollers which are in contact with each other under the action of pressing means. One of the three rollers has a smaller diameter than the other two rollers. Two rollers with which the toner image supporting member comes into contact are disposed in such a manner that the axes of the two rollers intersect each other and the portion at which the two rollers contact each other or are closest to each other forms a straight line relative to the direction of roller axis. According to one embodiment of the invention, the remaining one roller with which the supporting member does not contact, is formed as a crown roller, that is, a roller which has its largest diameter at the middle portion of the roller.
    • 公开了一种用于将调色剂图像定影在电子照相复印机中的调色剂图像支持部件上的装置。 定影装置包括在压制装置的作用下彼此接触的三个旋转辊。 三个辊中的一个具有比其他两个辊更小的直径。 调色剂图像支撑部件接触的两个辊以这样的方式设置,使得两个辊的轴彼此相交,并且两个辊彼此接触或彼此最接近的部分形成直线相对 到辊轴方向。 根据本发明的一个实施例,支撑构件不与其接触的剩余的一个辊形成为冠辊,即在辊的中间部分具有最大直径的辊。

    • An apparatus for determining the attitude of an artificial satellite by narrowing attitude candidates to a correct one in a short time. The apparatus has star sensors, a star catalog data base, star identification sections in each of which star images output from the star sensors are collated with a star catalog with respect to each star sensor to output a group of corresponding candidates, attitude computation sections for computing a value of an attitude candidate of the artificial satellite with respect to each corresponding candidate, an attitude updating section for updating the value of the attitude candidate on the basis of the star images output from the star sensor and the star catalog, and an attitude propagation section for computing the value of the attitude candidate at the present sampling time from the value of the attitude candidate at the preceding sampling time and the artificial satellite's angular velocity. An attitude candidate unification section for comparing and combining the values of attitude candidates into one candidate is provided in a loop including the attitude updating section and the attitude propagation section.
