Abstract: Disclosed is an exposure apparatus for printing a pattern of a reticle on different shot areas of the wafer in a step-and-repeat manner. In the disclosed apparatus, an image of an alignment mark of the reticle is printed, by use of a projection lens system, on each of some shot areas of the wafer which are selected as the subject of detection. By this, a latent image of the reticle mark is formed on each of the selected shot areas. The latent image of the reticle mark is detected by a microscope which may be a phase contrast microscope and, from the results of detection concerning all the latent images of the reticle mark, a reference (correction) grid representing the coordinate positions of all the shot areas of the wafer is prepared and stored. In accordance with the stored reference grid, the stepwise movement of the wafer is controlled at the time of the step-and-repeat exposures of the wafer. This assures improved throughput of the apparatus.

Abstract: In the disclosed moving picture camera with an adjustable rotary shutter, the shutter has a rotary shutter and an adjusting blade. The shutter adjusting blade is adjustable coaxially to the rotary shutter, which adjusts a shutter aperture angle. A transmission and a positioning motor adjust the adjusting blade relative to the rotary shutter. A potentiometer is connected to the shutter adjusting blade and to the rotary shutter, for measuring the position of the shutter adjustment blade in relation to the rotary shutter. The potentiometer generates a position signal indicating the actual position of the shutter adjustment blade in relation to the rotary shutter.

Abstract: A hard copy such as a printed wiring board is fabricated by exposing to radiation a liquid crystal cell in which a desired pattern is written and directing the pattern-carrying radiation projected from the cell by transmission or reflection to a substrate which is coated with a material sensitive to the radiation and disposed alignedly at an exposure position by optical registration. The duration of the exposure is controlled for a given light intensity and for the type of the coating material. A pattern may be written in one cell substantially simultaneously as another cell is used for the projection imaging. After a produced pattern is compared with a reference pattern, corrections may be effected through a processor which controls the writing of a pattern in a cell.

Abstract: A method and apparatus for exposure control of images formed by two dimensional light valves allows precise exposure control, high degree of exposure uniformity and immunity from defects in the light valve. The light valve is being imaged onto an object, for example a sheet of light sensitive material, and the image is scanned along the object either by moving the object or the image. The data to be imaged is entered into the first row of the light valve and as the image of the light valve is scanned along the object, the data in the first row is transferred to subsequent rows at a direction and rate that keeps the imaged data stationary relative to the object. By using a large number of rows the exposure of each image point on the object is the sum of many exposures, each exposure contributed by one row. The number of rows each bit of data travels is electronically controlled in order to determine the exposure generated by the data bit.

Abstract: A band of exposed and developed photographic film is transported longitudinally along a predetermined path. The film carries a series of images and each of the images has a pair of edges which are spaced longitudinally of the band and extend transversely of the latter. Transverse, strip-shaped segments of the band are photoelectrically scanned to detect abrupt density changes associated with the edges of the images. In addition, the band is sensed at a predetermined location of its path in order to ascertain the length of the band travelling by the predetermined location. The density and length data are sent to a microprocessor which uses the data to assign a position coordinate to each detected edge and its corresponding image. The position coordinates represent the positions of the images longitudinally of the band.

Each upper frequency speaker unit includes a middle frequency driver mounted in a sealed rear enclosure which is attached to the throat of a middle frequency horn. A constant directivity high frequency horn with a high frequency driver attached to a rear end is mounted coaxially in the middle frequency horn. Sharp cutoff active crossover filters divide the input signal into low, middle, and high frequency band signals which are separately power amplified. The middle frequency horn is adapted to function as a direct radiator at a lower end of the middle band and as a sectoral horn above an unloading frequency of the middle frequency horn.

Abstract: The present invention relates to a method and apparatus for carrying out the focusing of projected images. To carry out such focusing, an image sensor operates on a small section of the projected image to blow it up to a point where only the grains of the image become larger than the resolution of the sensor. The image set obtained is electronically scanned so that a signal is received which includes a low frequency band determined by the grain density and a harmonic span generated by the transitions between grains and interstices, whereby a differential voltage is created which is indicative of the state of focusing.
