    • A three-dimensional shape measuring method by which measurement of a three-dimensional shape is realized with an improved precision. Grid patterns comprising a plurality of one-dimensional grids 1, 2 and 3, each having a period and direction different from those of the others, are simultaneously projected upon objects to be measured, using different colors for each of the one-dimensional grids 1, 2 and 3. Subsequently, a grid image deformed in accordance with the three-dimensional shapes of the objects to be measured is imaged, the grid image is separated by colors into one-dimensional grid components of each color, a phase for each of the one-dimensional grid components is detected, and then, measurement values of the three-dimensional shapes are obtained on the basis of the detected phases. At the same time, by imaging the objects to be measured by use of white light, color information on the objects to be measured are measured as well.
    • 通过精度实现三维形状的测量的三维形状测量方法。 包含多个一维网格1,2和3的网格图案,每个网格图案具有与其它图形不同的周期和方向,同时投射到待测量的对象上,对于每个一维网格1使用不同的颜色 随后,对要被测量物体的三维形状变形的网格图像进行成像,将网格图像由颜色分隔成每种颜色的一维网格分量,每个颜色的相位 检测一维网格分量,然后基于检测到的相位获得三维形状的测量值。 同时,通过使用白光成像待测量的物体,也测量待测物体上的颜色信息。

    • A fuel cell apparatus includes a stack of fuel cells, first and second end plates disposed at opposite ends of the stack of fuel cells to press the stack of fuel cells and being connected by a fastening member, and a pressure plate disposed inboard of the first end plate. A concave portion is formed at an inboard surface of the first end plate and a convex portion is formed at an outboard surface of the pressure plate. The convex portion contacts the concave portion. The first and second end plates are coupled to the fastening member (or, a tension plate) by a serration and a bolt. An adjusting portion is formed in the first end plate, and the concave portion is formed in the adjusting portion. A load variance decreasing mechanism is disposed in series with the contact portion of the convex portion and the concave portion. A recess is formed in an electrical insulator disposed inboard of the pressure plate, and the pressure plate is disposed in the recess. The convex portion may include a spherical surface or a cylindrical surface. The load variance decreasing mechanism may include a plurality of sets of coned disk springs disposed in series with each other. The fuel cell apparatus may include an attaching member constituting a portion of the fuel cell apparatus and attaching the fuel cell apparatus to a vehicle.

    • The present invention relates to a starch ester having short- and long-chain acyl groups wherein hydrogens in reactive hydroxyl groups in the same starch molecule have been replaced by C2-4 short-chain acyl groups and C6-18 long-chain acyl groups. The degree of substitution by the short- and long-chain acyl groups are regulated so as to make the starch ester thermo-plasticized and moldable even in the absence of a plasticizer. Accordingly, the starch ester of the present invention can be used as a biodegradable thermoplastic plastic material which can be thermo-plasticized in the absence of a plasticizer.
    • 本发明涉及具有短链和长链酰基的淀粉酯,其中相同淀粉分子中的反应性羟基中的氢已经被C2-4短链酰基和C6-18长链酰基取代。 调节短链和长链酰基取代的程度,使得淀粉酯即使在不存在增塑剂的情况下也被热塑化和成型。 因此,本发明的淀粉酯可以用作可在不存在增塑剂的情况下热塑化的可生物降解的热塑性塑料材料。
