    • In coloration of a shaped article composed of a curable resin, the addition operation can be reliably conducted and a reliable coloration effect can be obtained in both the single-color addition and in the multicolor addition. A liquid-phase, non-colored photo-curable resin is cured by irradiation with laser light and a lowermost layer 5n is formed. A liquid-phase, photo-curable resin is applied on the upper surface thereof and a colored layer 5n-1 comprising a cured non-colored region and a liquid-phase pool region is formed. A color ink is drop-wise added to the liquid-phase pool region. The pool region is irradiated with laser light and cured to the same hardness as that of the non-colored region. A block-like coating film having the prescribed thickness if formed from the surface coating film produced by the color ink covering the pool region. As a result, the formation of the next layer (colored layer 5n-2) on the upper surface of colored layer 5n-1 can be conducted without obstacles. Colored layer 5n-2 through colored layer 53 are formed by repeating this process, a colored layer 52 is formed on the upper surface of colored layer 53, and then the uppermost layer 51 is formed on the colored layer 52.
    • 在由可固化树脂组成的成形制品的着色中,可以可靠地进行添加操作,并且在单色添加和多色添加两者中都可以获得可靠的着色效果。 通过照射激光使液相,无色光固化树脂固化,形成最下层5。 在其上表面上涂布液相光固化树脂,形成包含固化的无色区域和液相池区域的着色层5 N-1。 彩色油墨逐滴加入液相池区域。 池区域用激光照射并固化至与非着色区域相同的硬度。 如果由覆盖池区域的彩色油墨制成的表面涂膜形成具有规定厚度的块状涂膜。 结果,可以在没有障碍物的情况下,在着色层5的上表面上形成下一层(着色层5N-2-N)。 通过重复该方法形成着色层5 通过着色层5 3 <3>,在上表面上形成着色层5&lt; 2&lt; 的着色层5 3上,然后在着色层5上形成最上层5&lt; 1&gt; 1&lt; 1&gt;。

    • An objective of the present invention is to provide a lip type end face sealing device 6 having excellent sealability to different kinds of liquids on the both sides in the axial direction and having excellent durability. A case 61 tight fitted to an inner peripheral face 2a of a housing 2 comprises case members 611 and 612. One pair of seal lips 62 and 63 is integrally fitted to inner peripheral flange parts 611b and 612b, positioned oppositely each other in the axial direction, and opened in a tapered shape. One pair of the seal lips 62 and 63 is slidably contacted with flange parts 64b and 65b of slingers 64 and 65 tight fitted to an outer periphery of a rotary shaft 3. Pressure in seal internal spaces S2 between the both seal lips 62 and 63 and the both slingers 64 and 65 is released through a vent hole 22 opened on the inner peripheral face 2a of the housing 2, an air hole 611c opened on the case 61, and between the case members 611 and 612.

    • V-CAD data is prepared by dividing external data 12 consisting of boundary data of an object into rectangular parallelepiped cells 13 having boundary planes orthogonal to each other in accordance with octree division and separating the respective divided cells into internal cells 13a positioned on the inner side of the object and boundary cells 13b including a boundary face, and a modeling unit quantity of a prototyping material 7 is changed in accordance with sizes of the internal cell 13a and the boundary cell 13b of a modeling portion. The prototyping material 7 is a resin, lumber powder, a low-fusing-point metal, metal powder, ceramics powder or a mixture of a binder and one of these materials, and its modeling unit quantity is set in such a manner that the modeling unit quantity is smaller than a capacity of a corresponding cell and does not protrude from the boundary plane of the cell. As a result, by using the V-CAD data, a program for rapid prototyping can be simplified, and a model production time can be greatly reduced.
    • 通过将由对象的边界数据构成的外部数据12分割为具有根据八叉树划分彼此正交的边界面的长方体单元13,并将各分割单元分离成位于内侧的内部单元13a来准备V-CAD数据 包括边界面的物体和边界单元13b以及原型材料7的建模单位量根据建模部分的内部单元13a和边界单元13b的尺寸而改变。 原型材料7是树脂,木材粉末,低熔点金属,金属粉末,陶瓷粉末或粘合剂与这些材料之一的混合物,并且其建模单位数量被设定为使模型 单元数量小于对应单元的容量,并且不从单元的边界面突出。 因此,通过使用V-CAD数据,可以简化用于快速成型的程序,并且可以大大降低模型生产时间。
