Abstract: A method and apparatus for printing arbitrarily large circuit patterns using small field optics. The use of small field imaging optics allows the use of high NA lens designs capable of printing smaller geometries than otherwise would be possible. The field size in a first axis is extended by scanning an object and image past the lens; the field size in a second axis is extended by stitching the scans together in an overlapped fashion. This overlapped printing technique averages many random and systematic errors and allows the placement of field adjacencies within die boundaries. The effective field size of such a system is limited only by reticle size and stage mechanics. The apparatus further includes error correction loops for enhancing stage synchronization accuracy and for reducing field adjacency errors.

The workpieces contain holes where projecting pins of the registration pin assemblies are received. At least one of the registration pin assemblies contains a projecting pin of a non-circular shape when viewed end-on. A flanged barrel of the assembly is rigidly mounted to a planar support board. The projecting pin is spring biased within a sleeve that mounts in the barrel. The pin projects through a barrel aperture and is non-rotatively movable in the plane of the board within limits defined by the barrel aperture.

Abstract: An original layout pattern for reticle includes a tip pattern region, a scribe region formed around the tip pattern region, and alignment marks formed in the scribe region.

Abstract: A mask is used for mounting a sensitized sheet, such as a printing plate, onto the surface of an exposure drum. The mask, acting as an intermediary between the exposure drum and the printing plate, is a flexible sheet, with a top and bottom surface, that is mounted about the exposure drum. A groove formed within the top surface of the flexible sheet is used for securing the printing plate by means of a vacuum. A passageway formed within the flexible sheet connects the groove to the bottom surface and receives a vacuum from the exposure drum. Plates of different sizes are mounted to the exposure drum by interchangeable masks of corresponding sizes.

Abstract: A kaleidospherical device (10) made of a plurality of elongate, tapered tubes (12) and (14) bundled into a geodesically ordered arrangement, is described. The tubes are preferably comprised of three planar mirrors (22, 24 and 26) mounted together to form a triangular cross-section that is approximately, but not quite equilateral. The tubes taper along their length from a small end to a large end where the bundle of tubes forms a geodesic shape. The reflective surfaces of the three mirrors forming the tube face each other. That way, when an object to be viewed is placed adjacent the small end of the bundle, the tapered tubes form a reflection of the object as a spherical image positioned inside the kaleidosphere. The kaleidosphere (60) can be made as a hemispherically shaped member that mounts on a cabinet (62) for projecting a movie image or an image created by an object wheel (82) into the kaleidosphere. The kaleidosphere (96) can also serve as a lamp (90) or a chandelier.

Abstract: This invention is directed to the storing of digital information. This storage system comprises a number of layers of transparent or translucent material. In each layer there is a chemical or chemicals subject to change by being contacted with different electromagnetic wave lengths. For example, if there be eight layers then the chemical or chemicals in any layer is subject to be changed by an electromagnetic radiation of a wave length different than of the other seven layers. In this manner, with eight layers it is possible to have an eight bit byte. Actually, under premutations and combinations it is possible to have as many as eight bit bytes from the eight layers. It is conceivable that there may be more than eight layers such as sixteen layers of thirty-two layers. There is the possibility of storing large amounts of information in a small volume.

Abstract: An electric stapler is disposed at the bottom of a tray on which printed sheets are stacked, and is movable along the bottom of the tray. Printed sheets are aligned on the tray along a reference line. The stapler moves along the bottom of the tray and stops at determined points to staple the aligned sheets. A control section is stored with data about the number and location of stapling points proper for each sheet size. The size of printed sheets to be stapled is detected, and the movement of the stapler is controlled so that the stapler can staple at proper points for the detected sheet size.
