Abstract: This invention pertains to a method for making a cylindrically-shaped element, and particularly a cylindrically-shaped element for use as a base sleeve for printing or as a support for a print form. The method includes wrapping a sheet of a material having a first end and a second end to bring the second end adjacent the first end to form a base sleeve having an axial seam of the first and second ends. The first end has a non-linear edge having an amplitude. Portions between the first end and the second end overlap and form the axial seam. The method can include applying an imageable material adjacent an exterior surface of the base sleeve that covers at least a portion of the axial seam.

Abstract: A method for fabricating multilayer circuits comprising patterned conductive layers separated by dielectric layers and connected by vias in the dielectric, wherein the unfired dielectric layers are laminated as tapes or sheets over either a fired or unfired conductor layer while under a vacuum.

Abstract: A loop bin for an endless tape having long length contained in a zigzag fashion comprising a tape inlet from which the endless tape can be put in, a tape outlet from which the endless tape can be drawn out, and at least one tape transport mechanism provided substantially horizontal so as to divide an inside of the loop bin into cascading levels and for continuously feeding the zigzag endless tape on each level from the tape inlet to the tape outlet.

Abstract: An improved contact printing process is disclosed whereby better contact is achieved between magnetic master and copy tapes through use of fluid pressure. Slippage between copy and master tapes is prevented by applying fluid pressure to the tapes in an area defined by the width of the tapes at the point where replication is initiated, and extending upstream along the length of the tapes prior to replication.Slippage between copy and master tapes is prevented by applying fluid pressure to the tapes in an area defined by the width of the tapes at the point where replication is initiated, and extending upstream along the length of the tapes prior to replication.

Abstract: The present invention concerns a tape transporting device wherein mechanisms which can partially switch the master tape traveling direction have been established, and wherein a loop bin used for storing a master tape is established on a horizontal plane. As a result, the master tape exhibits no deformation attributable to gravity within said loop bin, and a since the copy tape can have a constant perpendicular or other angular orientation with respect to the master tape in the loop bin, the floor space needed for the tape transporting device can be minimized.

Abstract: A tape transport for driving a continuous master tape and a copy tape through a tape contact printing station at a very high speed. The master tape has a prerecorded signal the reverse image of which is transferred onto the copy tape by the tape contact printing station. The tape transport enables the master and copy tapes to maintain contact and registration with the required degree of accuracy to produce an acceptable signal transfer which generates a high quality video signal for use in home video cassette recorders and viewing equipment.

Abstract: A process and equipment is disclosed that is capable of duplicating magnetic tapes at speeds higher than 2.5 meters/second. Tape surfaces are selected that have sufficient roughness to readily permit air to bleed from between surfaces as they are held together by air pressure during the duplication process.
