    Abstract: In the manufacturing of flexible, large-area electronic modules such as flat-panel displays (FPDs), the high cost and low yields of currently available patterning equipment represent a significant barrier to cost-effective production. This invention provides a projection imaging system that can pattern very large, flexible substrates at very high exposure speeds with almost any desired image resolution. The master pattern to be imprinted on the substrate is contained on a mask which, similar to the substrate, is made of a flexible material The mask and substrate are scanned by rollers through the object and the image field, respectively, of a 1:1 projection lens. All of the rollers are driven by identical drive systems linked to a common motor; therefore, the scanning of the mask and substrate is perfectly synchronized. Both the mask and the substrate, along with their rollers, are mounted on a linear translation stage.

  • Patent number: 4080062
    Abstract: The disclosure describes a variable magnification optical mechanism in an image forming apparatus in which a varied image at a selected magnification of an original image is formed. A photosensitive body on which the varied image is exposed is moved at a definite speed (v) irrespective of the selected magnification (m) and optical means for transmitting the image of the original to the photosensitive body is driven at a speed ratio of v/m. The pre-running length (l) of the optical means is changed in accordance with the selected magnification (m) at a ratio of l/m so that coincidence of the original image and the variation image formed therefrom may be attained every time.

  • Patent number: 4073586
    Abstract: In a telecine equipment of the flying spot cathode-ray tube type with an oscillatory mirror, markers associated with the frames of a film are illuminated with a light spot of small dimensions, which substantially follows the motion of the marker associated with the frame being scanned. This is obtained by means of a small fixed light source, which is used for scanning the path followed by the marker associated with the film frame being scanned, using the same optical channel as for the frame scanning. This same optical channel, used in the reverse direction by means of a fixed mirror located behind the film, forms the image of the illuminated marker.

  • Patent number: 3997260
    Abstract: The invention relates to electrostatographic copiers and in a first embodiment an optical arrangement is provided in which the image of an original placed on a part-cylindrical platen is reflected via a first mirror through a movable scanning lens onto a second, rotating mirror and thence onto a photoconductive surface of a drum. The platen may be either cylindrical or flat and have the image of the original reflected from a first mirror which is so inclined and dimensioned that substantially the whole of the perpendicular projection of the original falls on the first mirror, the arrangement being such that the optical path length between the original and the drum surface is maintained substantially constant.

  • Patent number: 3992093
    Abstract: A document copying machine is disclosed, of the type in which the original moves reciprocally relative to an illumination slot so as to be exposed line-by-line from one end to the other, a receptor element, which may be a copy sheet taken from a supply stack, a selenium drum or other receptor surface, moving in one direction and having an image of the original transmitted to it by image beam guide devices located between the illumination slot and the receptor element. The machine has double the productive capacity of conventional copying machines where there is relative movement of the original and the exposure or illumination slot, in that a copy-producing image is transmitted, on relative movement of the original and the slot in one direction, on to a receptor element and a second copy-producing image is transmitted, on opposite relative movement of the original and the slot, on to a second receptor element or on to the same receptor element moved to a further position.
