摘要： A photographic copier has a first platform for supporting an original to be copied, and a second platform for supporting copy paper. A focusing system is disposed between the platforms and includes a plate which can be mounted at different distances from the platforms. The plate has a central opening which removably receives a tubular holder. The holder is supported in the opening by a ring which permits the position of the holder relative to the plate to be adjusted. Two lenses are removably mounted in the holder and serve to project an image of the original onto the copy paper. Different magnifications can be achieved in that the copier comes equipped with a variety of holders having different lengths, and a few selected lenses having different optical characteristics. The magnification is changed by simply interchanging holders and/or lenses, and adjusting the position of a holder to be used relative to the plate.

摘要： A copier has a movable housing which accommodates a support for an original to be copied, a source of illumination for the original, a lens system for forming an image of the original and a support for photosensitive material which is to receive the image. The housing has an opening in one of its sides and carries a hinged lid for lighttight sealing of the opening. A reflector is pivotally mounted inside the housing in the vicinity of the opening and can be moved between an operative position in which it intercepts the image from the lens system and an inoperative position in which it does not. When an image of normal size is required, the reflector is in its inoperative position and the image is projected onto the photosensitive material located inside the housing. When an image of large size is required, the reflector is brought into its operative position and the opening in the housing is uncovered. The reflector can then project the image through the opening and onto a large sheet of photosensitive material held on a wall or other suitable support.

摘要： A strip of originals is copied onto a band of copy material at high speed using a highly automated copier which measures the densities of the originals in the primary colors and calculates exposures from the densities. The calculated exposures for each original in each primary color are recorded. The band of exposed copy material is developed and the copies are evaluated. Unsatisfactory copies are marked. The band of copy material is subsequently cut into individual copies and the unsatisfactory copies, as well as the corresponding originals, are collected. These originals are recopied in a second copier which is far less sophisticated and expensive than the first copier. The exposures used to recopy an original are derived by applying correction factors to the recorded exposures for the original. By performing the recopying procedures, which are rather slow because they require manual operations, in a second copier, the output of the high speed copier can be maintained.

摘要翻译： 使用高度自动化的复印机将原稿带复制到高速复制材料带上，该复印机测量原色的原色的密度并计算密度的曝光。 记录每个原色中每个原始图像的计算曝光。 开发出暴露的复制材料的带，并对拷贝进行评估。 不满意的副本被标记。 随后将复印材料带切割成单独的副本，并收集不合格的副本以及相应的原件。 这些原件在第二台复印机中重复使用，这比第一台复印机要复杂和昂贵。 用于复印原件的曝光是通过对原始记录的曝光应用校正因子得出的。 通过执行由于需要手动操作而相当缓慢的重新启动程序，在第二复印机中，可以维持高速复印机的输出。

摘要： Apparatus for convoluting a web of photographic material onto a rotary core in a lighttight cassette has an elongated channel which is pivotably mounted in the cassette and whose outlet is normally tangential to the peripheral surface of the core. The outlet of the channel is detachably or permanently connected with a flexible or deformable strip-shaped element in the form of a link chain, plastic band, textile band or metallic band which surrounds a substantial part of or the entire peripheral surface of the core. When the leader of a web is introduced into and advanced beyond the outlet of the channel while the core rotates in a direction to convolute the web, the foremost part of the leader penetrates between the core and the flexible element and adheres to the peripheral surface of the core not later than upon the making of approximately two convolutions. During winding, the flexible element insures that the neighboring convolutions of the web on the core are tightly packed against each other. When the web is being withdrawn, the flexible element brakes the web and prevents clockspringing of convoluted material.

摘要： Apparatus for transferring photosensitive sheets from the transporting plane into the copying plane of a photographic copying machine has a suction chamber with a perforated cover having a flat upper side which defines the copying plane. The interior of the suction chamber is subdivided into one or more centrally located primary sections which are in direct communication with the intake of a suction pump and two or more secondary sections which communicate with the primary section or sections by way of narrow passages defined by internal partitions of the suction chamber so that a sheet which is advanced in the transporting plane to a position of register with the cover is attracted first to that portion or those portions of the cover which overlie the primary section or sections and thereupon to those portions of the cover which overlie the secondary sections. The number of primary and secondary sections which communicate with the intake of the suction pump is reduced when the apparatus is used for transfer of smaller sheets. The number of perforations per unit area of that portion of the cover which overlies the primary section or sections is greater than the number of perforations per unit area of that portion of the cover which overlies the secondary sections, and the combined cross-sectional area of perforations in communication with the primary section or sections is greater than the combined cross-sectional area of passages between the primary and secondary sections.

摘要： A wafer with a lacquer layer applied to it is checked automatically by lighting the wafer directly, so that the lacquer layer reflects the light. Resultant reflectance values of the reflected light are ascertained and buffer-stored and compared with corresponding values for a comparison wafer. It is ascertained whether the wafer is OK or defective from the result of the comparison in accordance with at least one predetermined judgment criterion.

摘要： The longitudinally transported strip passes and is pressed between two cooperating transport rollers. The rotation axes of the two rollers are normally parallel to each other. One roller is swingably mounted about a swing axis which intersects and is perpendicular to the rotation axis of the other, non-swingable roller. Edge sensors are displaced by the lateral edges of the transported strip, when the strip improperly shifts transversely. The force thusly exerted upon an edge sensor is transmitted, via a force-multiplying lever system, to the swingable transport roller, swinging the latter to a position such that the swung transport roller exerts upon a major surface of the transported strip a force whose transverse component is directed opposite to the direction of the improper transverse shift, resulting in automatic recentering.

摘要： In a method for checking semiconductor wafers and apparatuses for carrying out the method, a lacquer layer applied on a semiconductor wafer is checked. Initially, regions which are to be excluded from the check and surfaces which are to be checked, are ascertained. The checking is effected by direct illumination in such a way that the lacquer layer reflects light. The resulting values of the reflectance are determined and buffer-stored. A determination is performed for each surface as to whether or not it is to be accepted or rejected, in accordance with a predetermined evaluation criterion.
