  • Patent number: 6123415
    Abstract: In the ink jet recording apparatus for recording an image by supplying ink obtained by dispersing color material components in a solvent to a head substrate and by jetting ink drops containing at least the color material components to a recording medium on the basis of electrostatic force applied to the color material components, the recording apparatus comprises a driving circuit (107) for applying voltages to electrodes of an electrode array (102) arranged on a head substrate (101), in such a way that a first potential difference whose potential level relationship is reversed at a predetermined period between the two adjacent electrodes can be applied when the color material components are cohered and/or stirred on the head substrate, and a second potential difference different from the first potential difference between the two adjacent electrodes can be applied when the ink drops are jetted toward a recording medium.

  • Patent number: 5852453
    Abstract: An auxiliary substrate is provided so as to face a main substrate to which ink is supplied and the pattern of a voltage applied to an auxiliary electrode array formed on the auxiliary substrate is controlled. In a printing operation, the coloring material components are sent to the vicinity of an ink droplet emitting outlet and the coloring material components in the ink where the coloring material is dispersed in solvent are concentrated. Then, they are emitted from the ink droplet emitting outlet in the form of ink droplets and are forced to fly at a printing medium, thereby printing on the medium. In a non-printing operation, the auxiliary electrode array is controlled so that the coloring material components may be kept away from the ink droplet emitting outlet and the concentration of the coloring material components in the ink near the ink droplet emitting outlet is made lower than in a printing operation.

  • Patent number: 5835113
    Abstract: An ink jet printing apparatus, in which the ink having colorants distributed in a solvent is supplied over the electrode array on the surface of the head substrate such that the electrode array is completely covered by the ink, while voltages are applied to the electrode array to produce an electric field for exerting an electrostatic force on the colorants in the ink such that the colorants are compressed and ejected toward a recording medium. Each individual electrode constituting the electrode array can have a tip end portion projecting from the surface of the head substrate. The apparatus also has an element for compressing colorants distributed in a solvent of an ink and an element for ejecting the compressed colorants toward a recording medium which are provided separately. In addition, the apparatus can incorporate an element for conveying colorants in the ink through the ink supply passage toward the colorant ejection point on the electrode array.

  • Patent number: 5475210
    Abstract: An optical disk apparatus includes a semiconductor laser for emitting a light beam, and an automatic power control or APC circuit for driving the laser. A compound prism structure is optically coupled to the laser in an optical head section, and defines a first optical path for causing a front laser light to be projected onto a rotating optical disk and guiding a reflected light therefrom toward a first photodetector, and a second optical path for guiding a part of the reflected light toward a second photodetector. An output signal of the first photodetector is used to generate a reproduced information signal. An output signal of the second photodetector is fed back to the APC circuit as a front light monitor signal. A part of a laser control signal internally generated in the APC circuit is supplied through a wiring line to a noise reduction circuit as a laser noise monitor signal.
