摘要:
An electrophoresis display capable of displaying colors, yet having high contrast and a high reflectance on displaying white color. The electrophoresis display device includes a dispersion medium containing a liquid crystal and electrophoretic particles made of titania, etc. being dispersed in the dispersion medium, wherein the dispersion medium contains a dichroic coloring matter having dichroism with a high dichroic ratio as a first coloring matter and a dichroic coloring matter having dichroism with a low dichroic ratio and/or an isotropic coloring matter as a second coloring matter, provided that the first coloring matter and the second coloring matter have complementary colors each other. In this manner, white, black, and color displays are realized by a single capsule.

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. In this ink jet recording apparatus, a stable recording can be made by uniformalizing the density of the ink color material components on the head substrate and further by preventing the color material components from adhering onto the electrode.

A solid ion recording head using an ion generation device, capable of realizing a uniform and stable recording and a compact physical configuration. The head includes a head support member in substantially rectangular cross sectional shape for supporting the ion generation device on a lower side of the rectangular cross sectional shape facing against the recording medium and the driving circuits on side faces of the rectangular cross sectional shape. The ion generation device includes control electrodes having ion passing holes which are arranged such that picture dot to be recorded on the recording medium from each one of the ion passing holes is recorded on a spot around which picture dots already recorded by other ion passing holes are distributed symmetrically on both sides. The control electrodes may have a structure in which a plurality of the ion passing holes are provided with respect to each picture dot to be recorded.

The date driving mechanism of a watch comprises a date driving wheel having a partially teethed portion engaged with teeth of a calendar driving wheel which in turn drives a calendar display dial so as to advance the calendar display dial a given amount each rotation of the date driving wheel. A cam integral with the date driving wheel engages a pivotal control member so as to hold the control member against the calendar driving wheel normally to restrain movement of the date dial. The cam has a flat side so as to release the calendar driving wheel from restraint when being driven by the teethed portion of the date driving wheel, thereby relieving load on the date driving wheel. The control member has a resilient arm which yields to permit manual correction of the calendar display.

An inclination sensor includes: a case having a turning shaft section projected in a lateral direction on a front surface thereof; magnetism detecting means fixed on an upper side of the turning shaft section; a pair of magnets fixed in parallel to a rear surface of the case to be located on both sides of the magnetism detecting means; a pendulum axially supported by the turning shaft section to turn freely; and a pair of ferromagnetic bodies fixed on an inward surface of the pendulum. When the case inclines, one of the ferromagnetic bodies approaches the magnetism detecting means, and a magnetic circuit is closed by the pair of magnets and one of the ferromagnetic bodies. Magnetic fluxes of the magnets pass over front and rear surfaces of the magnetism detecting means.

Electrophoresis display devices using charged particles which move in each cell in accordance with the electrophoresis caused by electrodes neighboring the cell. First through third electrodes are used to provide the electrophoresis to the charged particles in a dispersion liquid of each cell. The first and the second electrodes are formed in parallel with each other on a side of a first board and the third electrode is formed on a second board 5 to intersect with the first and the second electrodes. The first electrode may be applied with an initial voltage, a first hold voltage and a rewriting voltage between the initial voltage and the first hold voltage in an order of the first voltage, the rewriting voltage and the first hold voltage. The second electrode may be applied with intermediary voltage between the initial voltage and the rewriting voltage to the first electrode. The third electrode may be applied with a color display voltage different from the intermediary voltage and second holds voltage in synchronism with the first hold voltage. The dispersion liquid may be sealed by a microcapsule or the like and a position of the microcapsule may be fixed by a projection formed on one of the boards.
摘要:
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.
