Abstract: A contact printer for printing negatives in rows and columns directly onto photographic paper comprises a flat smooth base plate having a pair of upstanding pins adjacent one side edge. The pins are mounted in slots so as to be adjustable longitudinally of the side edge both in spacing and in distance from the bottom edge. The negatives are placed in rows and columns within an archival preserver sleeve which has holes along one side edge engaged over the pins to locate the sleeve and therefore the negatives on the base plate. Photographic paper is inserted under the sleeve and is located on the base plate by engagement with the pins and by alignment of the bottom edge of the paper with the bottom edge of the base plate. This ensures that the negatives are properly aligned with the paper. A transparent cover plate is also provided to press the negatives onto the paper for exposure of the paper by light directed through the transparent cover plate.

Abstract: Disclosed herein is a method of forming a graphic image having the appearance of three-dimensionality, the method comprising the steps of: providing a preformed lenticular film having a flat side and having a side with lenticules opposite the flat side; and printing an image on the flat side of the lenticular film using web fed printing to produce a graphic image web in which the perceptible image possesses photographically acceptable quality, wherein the image elements are printed on the lenticular film at an angle which corresponds to the pitch of the lenticules of the lenticular film.
Abstract: In a rear-projection screen comprising a Fresnel lens and a light-diffusing member containing light-diffusing fine particles, it is intended to decrease the moire and to give no dark feeling at the border even when projection systems are set in a short projection distance. For this end, in the rear-projection screen of the present invention, the thickness of the light-diffusing member is made larger at the border than at the center of the rear-projection screen, or the concentration of the light-diffusing fine particles contained in the light-diffusing member is made larger at the border than at the center so that the rear-projection screen can have light diffusion properties greater at its border than at its center. Here, any of a flat plate, a flat sheet and a lenticular lens sheet can be used as the light-diffusing member.
Abstract: A light source having a solid state laser emitting a beam that is separated into a number of segments. Each segment is frequency shifted by a different amount so that the segments do not substantially overlap in the frequency domain. Each segment passes through a short focal length lens element of a fly's eye array to be dispersed onto a mask plane for evenly illuminating a mask. The lens elements of the fly's eye array are contained within a small region in comparison to the width of the dispersed beam segments, such that each beam segment contributes illumination to the entirety of a common portion of the mask.
Abstract: A protective mask is provided for use with a pellicle which is mounted to a photomask during photolithography, with a light source being directed toward the photomask. The pellicle includes a pellicle membrane mounted to a pellicle frame by a first adhesive layer and with the pellicle frame being mounted to the photomask by a second adhesive layer. The protective mask is fabricated of an opaque material and is positioned between the light source and the two adhesive layers to shield them from the light source.

Abstract: An imaging system is disclosed which incorporates a gradient index lens array to transmit focused light onto an image medium with increased Depth of Focus (DOF) and no loss of radiometric efficiency. The lens array is first constructed so that its exit pupil is generally symmetrical. This first step increases the radiometric efficiency of the lens array relative to prior art lens arrays. In a second step, the DOF is increased by reducing a quantity n.sub.o .sqroot.AR which is associated with the lens, n.sub.o being the axial refractive index of the fibers comprising the lens array, .sqroot.A being the gradient index constant of the material comprising the lens array and R being the radius of the individual optical rods, As this quantity is reduced, the DOF increases consistent with a trade off of reduced radiometric efficiency. Since the efficiency was initially increased from some optimum value, the DOF can be increased until the desired radiometric efficiency level is reached.
Abstract: An apparatus for exposing a pattern, formed on a mask, on each of a plurality of partitioned areas on a photosensitive substrate by a step-and-repeat scheme includes a projection optical system for projecting the pattern of the mask on the photosensitive substrate, a substrate stage for holding the photosensitive substrate and two-dimensionally moving the photosensitive substrate within a plane perpendicular to the optical axis of the projection optical system, a detection unit for projecting a pattern image having a predetermined shape on the photosensitive substrate and photoelectrically detecting light reflected by the photosensitive substrate to detect a position at each of a plurality of points on the photosensitive substrate along the optical axis of the projection optical system, and a measurement unit for, when each of a plurality of measurement points in a partitioned area on which a pattern of the mask is to be exposed next coincides with or approaches the pattern image, detecting an offset amount b
Abstract: A longitudinal-stripe lenticular lens screen and a transverse-stripe lenticular lens screen are superposed, and a light diffusing agent is mixed only in the longitudinal-stripe lenticular lens screen. Therefore, the light transmittance is high although the angle of view can be three-dimensionally widened by the two lenticular lens screens. In addition, since scan lines of an image are blurred by two diffusion planes, Moire becomes inconspicuous.

A second drive systems is provided for applying, to the table, an acceleration the same as that of the base plate, in order to correct the relative positional aberration between the base plate and the table, induced by the vibration of the base plate generated when the table is driven by the first drive system.
Abstract: A paper mask device in which the position of longitudinal masks can be changed without damaging a web of printing paper. When it is changed from the borderless printing to the printing with border, one ends of the longitudinal masks are moved inwardly toward each other by means of a first transfer unit while keeping the other ends overlapped on the edges of the printing paper. A second transfer unit then operates to move the other ends of the longitudinal masks inwardly to set the width of the print size. The longitudinal masks can be overlapped on both edges of the printing paper without damaging it.
