    摘要: An alignment apparatus for mask and wafer each having alignment marks provided in a narrow strip like area between circuit patterns is disclosed, which mask and wafer are used in manufacturing semiconductor circuit elements. In the apparatus, the mask and wafer are scanned to obtain scan signals by means of which the amount of relative deviation between the alignment marks on mask and wafer is detected. By means of the detected signal, an alignment is effected between the mask and wafer in the apparatus. For this type of alignment apparatus, there is a problem that since the alignment marks are provided in the narrow strip like area, no coincidence between the scanning position and the strip area is attainable with pre-alignment accuracy. Improvement in the alignment apparatus according to the invention lies in that a reading of alignment marks is initiated after the coincidence is photoelectrically detected.

    摘要: This invention relates to a photo-electrical detecting apparatus for forming a dark-field image of an object on a one-dimensional image sensor and reading said image photo-electrically. The apparatus includes a telecentric objective lens, and a light source image is formed on the clear aperture plane of said lens, said image being in focus in a direction on said plane and out of focus in a perpendicular direction. A line- or band-shaped area of the object is illuminated by the light from said light source image. Thus a dark-field image of the object is formed on said one-dimensional image sensor by providing, on a plane equivalent to said aperture plane, a filter which intercepts the normal reflected light from said object and transmits the scattered light therefrom.

    摘要: An improved photoelectric detecting apparatus is disclosed in which a subject surface containing a pattern which diffracts light in a predetermined direction is scanned with spotlight and the diffracted light coming from the pattern is detected by means of photoelectric element so as to read out information of the pattern. The apparatus comprises a first photoelectric element for detecting the light diffracted in the predetermined direction, a second photoelectric element adapted for detecting light diffracted in directions other than the predetermined direction and an operational circuit for operating the signal derived from the first photoelectric element and that derived from the second one. Thus, when there is any diffractive matter such as flaw, dust and the like on the subject surface, diffracted light from the diffractive matter is detected by both the first and second photoelectric elements whereas diffracted light from the pattern is detected only by the first photoelectric element. By operating the outputs of the two photoelectric elements only the necessary information of the pattern can be read out.

A thin hollow cylindrical wall is formed on a link lever of the carburetor. After the adjusting screw is screwed into the threaded hole of the hollow cylindrical wall, the reduced diameter portion of the adjusting screw is cut. Then, the top portion of the hollow cylindrical wall is bent inward for irremovably fixing the adjusting screw onto the link lever.

    摘要: An image signal processing method and apparatus for practicing the method are capable of identifying and differentiating information not having tonal rendition such as characters and linetone images from information having tonal rendition such as photographs and pictures, based on the difference of signal characteristics, for example based on the fact that the spatial frequency distribution in portions of an image not having tonal rendition are in the higher frequency range compared to that of the portions of the image having tonal rendition. The method and apparatus are also capable of conducting different processes on the identified different images.
