  • Publication number: 20080152795
    Abstract: Thermal transfer printing method and apparatus are provided to make initial character image data left on a spent ink ribbon illegible. In the method, after forming an initial character image FGi1 on an ink layer 11b in black of the ink ribbon 11, a forefront position S1 of the ink layer 11b is aligned with a forefront position S2 of an intermediate transfer film 25. Then, overwrite character image data UGD1 is applied on a thermal head 19 to produce a first superimpose character image KG1i1 on the ribbon 11 and a first superimpose character image KG1m1 on the film 25. After that, the forefront position S1 of the ink layer 11b is shifted from the forefront position S2 of the film 25 by a predetermined distance and further, the overwrite character image data UGD1 is applied on the thermal head 19 to produce a second superimpose character image KG2i1 on the ribbon 11 and a second superimpose character image KG2m1 on the film 25.

  • Publication number: 20080079799
    Abstract: A card manufacturing method for manufacturing the card and a card manufacturing apparatus for manufacturing the card are provided. The card 51 includes a card base 1, a first receptor layer 1a arranged on one side of the card base 1 to contain a sublimation-ink image 8, a protecting layer OC1 laminated on the first receptor layer 1a and an invisible-ink image 10 formed on the protecting layer OC1. Owing to the interposition of the protecting layer OC1 between the sublimation-ink image 8 and the invisible-ink image 10, the card 51 is capable of suppressing color fading of a sublimation ink in the image 8 in spite of a card structure where the sublimation ink and an invisible ink are printed so as to overlap each other, allowing the card 51 to be used for a long time.

  • Patent number: 4948401
    Abstract: A gas mixture separator having adsorbent (1) with pressure dependent adsorptivity includes a cylinder (2) and a piston (3) as a means of pressure modulation necessary for the adsorption and desorption of gas components to be separated. Ingredient gas to be separated is fed to the cylinder through an inlet valve and inlet (5) to flow into contact with the adsorbent (1) by pressure produced by the piston (3) moving toward top dead center in the cylinder (2). The unadsorbed gas component passes through the adsorbent and exits the cylinder through the outlet (4) and associated outlet valve. The adsorbed gas component is desorbed during depressurization of the cylinder (2) during the retraction stroke of the piston (3) and exits through the outlets (8, 6) therefore. Adsorbed gas is introduced into the cylinder (2) through an inlet (7) therefrom from an additional separator for recovery of energy therefrom.
