    • A method of inspecting unevenness of a partition wall surface of a honeycomb structure includes the steps of: allowing a diffusion light to enter from one end face 8 side by a predetermined lighting means 3 and to exit from the other end face 8 side of the honeycomb structure 2 after passing it through the inside of the cells, allowing the exited diffusion light to pass through a translucent screen 4 disposed on the other end face 9 side of the honeycomb structure 2 to act as a transmitted light, projecting a transmitted image 13 by means of the tone of the transmitted light onto the transmitted light side of the screen 4, picking up the transmitted image 13 projected on the screen 4 by an imaging means 5, and analyzing by an analyzing means 6 the gray level of the obtained image to inspect for each cell the degree of the surface unevenness of the partition walls. This method enables easy inspection on the surface unevenness of the partition walls of the honeycomb structure 2.
    • 检测蜂窝结构体的隔壁表面的不均匀性的方法包括以下步骤:允许扩散光从预定的照明装置3从一个端面8侧进入并从蜂窝的另一端面8侧退出 结构体2在将其通过电池内部之后,允许出射的扩散光通过布置在蜂窝结构体2的另一端面9侧上的半透明屏幕4以作为透射光,将透射图像13投射到 通过成像装置5拾取投射到屏幕4上的透射图像13,并将所获得图像的灰度级分析为 检查每个电池的分隔壁的表面不均匀度。 该方法能够容易地检查蜂窝结构体2的隔壁的表面凹凸。

    • A shape-measuring device 1 measures the shape of a object to be measured 1 in which segments are arranged and bonded in rows while relatively moving the object 1 in one direction. The shape-measuring device includes rollers 31 provided corresponding to the rows of segments and displaced to follow unevenness of an end face 1a of the object while being rotated on the end face 1a due to the relative movement, detection means 35 provided corresponding to each roller 31 and detecting the amount of displacement of each roller 31, and calculation means 37 for calculating shape data of the object 1 based on the amount of displacement of the roller 31 detected by the detection means 35. The shape-measuring device 1 can accurately and promptly measure the shape of the object such as a DPF in which segments are bonded in rows.
    • 形状测量装置1测量在将物体1沿一个方向相对移动的同时以行排列并结合的被测量物体1的形状。 形状测量装置包括对应于这些行段设置的辊31,并且随着相对移动而在端面1a上旋转的同时移动以跟随物体的端面1a的不平坦,检测装置35对应于 每个辊31并检测每个辊31的位移量,以及用于根据由检测装置35检测到的辊31的位移量来计算物体1的形状数据的计算装置37.形状测量装置1可以 准确且及时地测量诸如DPF的物体的形状,其中段被结合成行。
