    • With the conventional radiating truss roof support array, the inner-truss connecting members form multiple complete rings radiating from the central portion of the roof to the periphery at fixed intervals. When tension is applied to the periphery of the roof, a constricting annular compression is generated in each of the concentric rings of inner-truss connecting members. By this mechanism, the tension applied to the periphery is somewhat dissipated, and a less than optimal effect on the curvature of the dome of the roof is achieved by a given amount of tension applied to the periphery. The present invention concerns a radiating truss roof support array constructed in such a manner as to eliminate the above described problem of induced annular constriction in the concentric rings of inner-truss connecting members. This goal is achieved by interrupting the concentric rings of inner-truss connecting members at fixed intervals so that predetermined adjacent trusses are not connected together by the above mentioned inner-truss connecting members. The concentric rings of inner-truss connecting members thus formed are incomplete at predetermined portions and the annular constriction is thus eliminated. Thereby, the tension applied to the periphery of the structure is used to maximum effect in maintaining the curvature of the dome of the roof.
    • 使用传统的辐射桁架屋顶支撑阵列,内部桁架连接构件形成从固定间隔从屋顶的中心部分到周边辐射的多个完整环。 当对屋顶的周边施加张力时,在内桁架连接构件的每个同心环中产生收缩的环形压缩。 通过该机构,施加到周边的张力有些消散,并且通过施加到周边的给定量的张力来实现对屋顶的圆顶的曲率的不太好的效果。 本发明涉及一种辐射桁架屋顶支撑阵列,其以这样的方式构造,以消除上述在内桁架连接构件的同心环中引起的环形收缩的问题。 该目的通过以固定间隔中断内桁架连接构件的同心环来实现,使得预定的相邻桁架不通过上述内桁架连接构件连接在一起。 如此形成的内桁架连接构件的同心环在预定部分是不完整的,因此消除了环形收缩。 因此,施加到结构的周边的张力用于保持屋顶的圆顶的曲率的最大效果。

    • A chord truss roof includes a ring-girder, cross beams arranged radially around the ring-girder, chord members stretched between the respective cross beams and the ring-girder. The roof supports itself by tensioning the chord members. The ring-girder has an upper compression ring, a lower tension ring, and plural struts connecting the two rings. The chord members arranged opposite one another with both end portions of the tension ring interposed therebetween are connected to the corresponding end portions of the tension ring, and are joined to one another via connection members which are disposed between both end portions of the tension ring. Further, each strut is provided along a line which bisects the angle made by a corresponding chord member and the plane defined by the tension ring.

    • In the related art of a method called a gloss mark, clear toner capable of adjusting glossiness without varying color phase has been used in order to prepare a gloss mark. However, a development device for clear toner is necessary in addition to a development device for colored toner. Accordingly, there has been a problem of upsizing and cost increase of an image forming apparatus.The image forming apparatus of the present invention forms a gloss mark only with colored toner without using clear toner. Specifically, at an area of which gloss is to be lowered, a part of colored toner required for forming an image is formed and fixed on a sheet, and then, the residual quantity which is not formed before the fixing out of the colored toner required for forming the image is formed and fixed so as to be superimposed to the fixed colored toner.
    • 在称为光泽标记的方法的相关技术中,为了制备光泽标记,已经使用了能够不改变色相来调节光泽度的透明调色剂。 然而,除了用于彩色调色剂的显影装置之外,还需要用于透明调色剂的显影装置。 因此,存在图像形成装置的大型化和成本增加的问题。 本发明的图像形成装置仅使用彩色调色剂形成光泽标记,而不使用透明调色剂。 具体地说,在要降低光泽的区域,形成图像所需的一部分有色调色剂并固定在片材上,然后在彩色调色剂定影之前未形成的剩余量需要 为了形成图像而形成和固定,以便与固定着色的调色剂重叠。
