摘要:
An electroosmotic ink printer comprising a head having an array of recording electrodes successively arranged to define a print line along one edge of the head. A common electrode is provided in spaced overlying relation with the recording electrodes. Between the electrode array and the common electrode is a means for electroosmotically moving ink in a direction toward the print line and in an opposite direction depending on an electrical potential applied to the recording electrodes with respect to the common electrode. A memory stores a video input signal in a plurality of storage locations corresponding to the recording electrodes for delivery in parallel form to a modulator for generating individual recording signals corresponding to the recording electrodes. Control means activates first and second groups of the recording electrodes by successively applying the individual recording signals thereto to cause the ink to move to the print line and deactivates the remainder of the recording electrodes by successively applying a deactivating potential to the electrodes of the group other than those to which the recording signals are applied.
摘要:
An electroosmotic ink printer head comprising a dielectric support having a surface defined by longitudinal front and rear edges and a pair of transverse edges. A plurality of first electrodes is successively arranged on said surface extending rearward from the front side of the support. A porous member is provided to overlie the first electrodes in contact with said surface. On the porous member is a second, liquid-permeable electrode on which is provided a means for supplying ink thereto to allow it to permeate therethrough to the porous member. A third electrode is located adjacent to each outermost one of the first electrodes and to the longitudinal front edge. A potential is applied to the third electrode with respect to the second electrode to cause the ink in the porous member to electroosmotically move in a direction from the third electrode to the second electrode. The ink which might wet the front edge of the support is pulled rearward by the electroosmotic movement.

A thermal transfer recording sheet is produced by placing, on one side of a sheet-like heat-resistant substrate successively along the surface, one or more thermal transfer recording layers containing a recording material which contains a binder material and a coloring material and whose viscosity is lowered and controlled by temperature-raise recording control, so that transferability to recording medium is imparted, and a thermal transfer coating layer containing a hot-melt material which is miscible (compatible) with at least a part of said binder material.The thermal transfer recording using said thermal transfer recording sheet is characterized by first subjecting the thermal transfer coating layer to temperature-raise recording control, forming a film of the hot-melt material on the surface of the recording material at least on a portion to which the recording material is transferred, and conducting thereon thermal transfer recording as usual. By this thermal transfer recording, the unevenness of transfer can be reduced and the recording sensibility can be improved.
摘要:
A thermal transfer sheet comprising a heat resistive base, a thermally transferable ink layer on one side of the base, and auxiliary particles distributed in the layer so that they partially emerge from the surface of the layer to present an irregular surface. The transferable ink layer comprises a mixture of a coloring agent and a hot melt binder, the mixture being transferable to a writing surface in response to application of heat to the other side of the base to provide continuous tone rendition.
摘要:
A thermal transfer recording apparatus is disclosed and includes a recording medium sheet formed of a plastic film material having numerous minute voids therein, and a thermal recording sheet formed of a heat resistive base sheet with opposing surfaces and a thermal transfer layer coated onto one of the opposing surfaces of the base sheet. The thermal transfer layer comprises an ink material containing a binder material and being transferable to the recording medium sheet, and particles which are solid at room temperature and are mixed into the transfer layer in order to form minute protrusions on a surface of the thermal transfer layer. The apparatus also includes a heater for raising the temperature of the thermal transfer layer in a controlled manner so as to decrease the viscosity of the thermal transfer layer. The recording medium sheet can, alternatively, be provided with a coated layer coated onto the surface of the plastic film and comprises a coated layer material, and particles which are solid at room temperature and have a diameter greater than the thickness of the coated layer material, so as to provide a roughened surface to the coated layer.

摘要:
Two electron beams are used to scan a striped color phosphor pattern arranged normal to the scan line in succession so as to increase the total amount of photon emission during the interval between successive line scans. The two beams are oscillated parallel to the scan line so as to increase the dwell time of impinging electrons on the phosphor stripe with a consequential increment in brightness. Beam sensing elements are located in a predetermined positional relationship with the phosphor stripes. Impingement of the scanning beams upon the sensing elements produces an index signal representing the nonlinearity which may be present in the horizontal deflection waveform, which signal is stored for the interval of a subsequent raster scan and retrieved nondestructively at the start of each line scan. The retrieved signal is modulated in frequency with a signal representing the time it takes for the beam to traverse the entire phosphor stripes to compensate for the so-called pincushion distortion. The frequency-modulated index signal is delayed so as to align it in phase with the start of each line scan. The phase-corrected index signal is used to sample a received primary color components in succession to provide a dot-sequential signal which is used to modulate the first beam. A predetermined delay time is introduced to the dot-sequential signal prior to the modulation of the second beam. Second beam sensing elements are located parallel to the phosphor stripes. Impingement of the scanning beams upon the sensing stripes results in two start-of-line index signals which are discriminated from each other by modulating the second beam with a pilot signal. The discriminated signals are compared in phase to compensate for a delay time error which may have been introduced to the intensity modulation of the second beam.
摘要:
A layer of fresh colorant is deposited on a first drum. Solvent is selectively deposited on a second drum in contact with the colorant layer in response to an electrical signal representing the density of a picture element. The colorant layer is subsequently brought into contact with first the solvent on the second drum and then with a recording medium to transfer the portion of the colorant layer which contacts the solvent to the recording medium.

A layer of colorant is deposited on a transfer base. Solvent is deposited on a portion of the colorant layer or a recording medium in response to an electrical signal representing the density of a picture element. The colorant layer is subsequently brought into contact with the recording medium to transfer the portion of the colorant layer where the solvent is deposited from the base to the recording medium.
摘要:
Transfer recording is carried out by driving in press-contacting a recording medium, e.g. a paper and a recording material sheet such as an ink transfer sheet, in a gap between a platen and a thermal head, and improvement is to apply a solvent, e.g. of liquid state and having volatility, on said paper, thereby high speed thermodissolving transfer is made by heat of said heated points, and recording with continuous gradation is obtainable.
