Abstract: A transferable dye medium for use in a thermal printer is made by applying a layer of dye material to a base layer; softening the applied layer of dyed material, as by heating same, and then calendering the softened, dye-coated base layer.

Abstract: The aim is to prevent damage to the printing surface of plastic intaglio plates. The radius of the plate cylinder 14, of the impression cylinder 11, and of the transfer drum 2, which is located between the units, is identical. The plate cylinders 14, 24 and the impression cylinders 11, 21 are arranged such that the lines L1 and L2 are located parallel to one another. The grippers 12, 22 are arranged such that the gripper 12 of the impression cylinder 21 is at the point P21 when the gripper 12 of the impression cylinder 11 is at the point P11. Consequently, a sheet of paper which has been transferred from the impression cylinder 11 to the transfer drum 12 at the next point P1 is transferred to the next point P2 by the rotation of the transfer drum 2. Since the phases of the plate cylinders 14 and 24 are in correspondence, the stripping blade is stopped in the same relative position in the case of all the units.

Abstract: S01156 MAGNETIC HEAD ASSEMBLY A magnetic head assembly comprising a deflectable piezo-electric member, such as a bi-morph leaf assembly, adapted for deflection in response to a voltage applied thereto, a magnetic head mounted on one end of the piezo-electric member and a U-shaped holder for the piezo-electric member. The U-shaped holder is formed of resilient material and has a pair of legs whose free ends are spring biased toward each other. The end of the piezo-electric member which is remote from the magnetic head is positioned between and clamped by the spring biased free ends of the legs of the holder. In one embodiment, a voltage is supplied to the piezo-electric member by a pair of plates, each formed of insulating material, with the clamped end of the piezo-electric member sandwiched between these plates, and with conducting member provided on at least one of the plates, and in electrical contact with the piezo-electric member.

Abstract: An intaglio plate that can be used in gravure printing is formed from a sheet (8a) made of a thermoplastic resin and wrapped around a metal cylinder (17). A laser source (24) irradiates the circumferential surface of the sheet (8a) to form concave portions or cells (15) in response to the tones of a picture. Preferably, a semiconductor laser is used with a resin containing carbon as a heat-absorbing material; the laser beam is modulated in response to image data whilst being translated past the rotating cylinder under computer control. … …

Abstract: A graphic image display system allows image data input through an data input apparatus to be displayed precisely. The graphic image display system is also able to display graphic images with satisfactorily high resolution. The graphic image display system according to the present invention comprises a scanning laser beam and a thermal liquid crystal cell. The system further includes a transparent data touch tablet secured to a display screen. Auxiliary laser detectors may be added for reading the image written in the liquid crystal cell. Preferably, a common laser optical system is used to generate the display image and to read the written image.

Abstract: THERMAL TRANSFER PRINTING METHOD AND PRINTING PAPER THEREFOR In a thermal transfer-type printing method in which an image is formed on printing paper by the selective transfer thereto of disperse dye from a dye carrier of flexible sheet material in response to the selective application of thermal energy to the carrier while in contact with a surface of the printing paper, the latter is comprised of a base of cellulose fibers and resin into which the disperse dye diffuses for producing a clear definition of the image. The resin is desirably polyester or acetyl cellulose either in the form of fibers which are co-mingled with the cellulose fibers in the base of the printing paper, or in the form of a coating on a surface of the paper base. After the image has been formed by thermal transfer on a surface of the printing paper, a thin transparent film, preferably of polyester, is laminated over the printed surface by a polyester adhesive and the application of heat and pressure so that recrystallized disperse dye remaining on the surface of the printing paper is further diffused into the polyester adhesive.
