    • The undercoating composition of the invention, useful for providing an undercoating layer for a top coat of a photosensitive resist layer on a substrate surface, comprises, as a principal ingredient thereof, a condensation product obtained by the condensation reaction between a hydroxy-substituted diphenylamine and a melamine compound substituted on the nitrogen atoms with methylol groups and/or alkoxymethyl groups. The undercoating obtained of the composition is highly resistant against the attack by the overcoating solution applied thereon so that the fidelity of the pattern reproduction by the photolithographic technique is greatly improved by virtue of the absence of any disorder at the interface between the undercoating and top coat layers. The advantage is further increased when the undercoating composition further comprises a photoextinctive agent, e.g. a dye, having absorptivity in the wave length region where the photosensitive resist of the top coat has sensitivity.

    • A measuring endoscope for making three-dimensional measurements of a object without using a special lattice and without hampering direct observation of the object. The measuring endoscope includes a light supply source for supplying illumination, and an illumination variation device for providing a plurality of particular illuminations, and illumination transmission means including a plurality of fiber optic cables. The fiber optic cables have a first input section separated from a second input section. The second section receives one particular illumination which the first section does not. At the output end of the fiber optic cables, fiber optic cables from the first section are interlaced, row-by-row with the fiber optic cables from the second section. An illumination lens then directs the light from the fiber optic cables onto the object. A lattice-shaped light pattern then appears on the object. Light reflected from the object is received by an objective lens system and is directed to an imaged sensor. The image sensor includes a large number of regularly arranged picture elements. Image processing devices then convert the received image into electrical signals. The image processing means process selected electrical signals from among all electrical signals received. These selected electrical signals are obtained from picture elements from positions where the lattice of the object image is formed on the light receiving surface. These selected electrical signals may then be processed to provide a three-dimensional measurement of the object. A control device controls the supply of light to the fiber optic cables to ensure that the light is emitted from the fiber optic cables in a lattice form. Finally, a display device connected to the image processor provides a display according to the three-dimensional image of the object.
    • 一种测量内窥镜,用于在不使用特殊格子的情况下进行物体的三维测量,并且不妨碍对物体的直接观察。 测量内窥镜包括用于提供照明的光源和用于提供多个特定照明的照明变化装置,以及包括多个光纤电缆的照明传输装置。 光纤电缆具有与第二输入部分分离的第一输入部分。 第二部分接收第一部分没有的特定照明。 在光纤电缆的输出端,来自第一部分的光纤电缆与第二部分的光纤电缆并排。 然后照明透镜将来自光纤电缆的光引导到物体上。 然后在物体上出现格子状的光图案。 从物体反射的光由物镜系统接收并被引导到成像的传感器。 图像传感器包括大量规则排列的图像元素。 图像处理装置然后将接收的图像转换成电信号。 图像处理装置从所接收的所有电信号中处理所选择的电信号。 这些选择的电信号是从在光接收表面上形成物体图像的格子的位置的图像元素获得的。 然后可以处理这些所选择的电信号以提供对象的三维测量。 控制装置控制向光纤电缆的光的供应,以确保光以格子形式从光纤电缆发射。 最后,连接到图像处理器的显示装置根据对象的三维图像提供显示。
