摘要:
An ink-jet recording ink contains at least a colorant, a moisturizer, water and a water-soluble substance capable of undergoing polycondensation along with vaporization of the water, in which the colorant is a chelate azo dye.
摘要:
In ink containing a colorant, a humectant, a penetrant, water, and a water-soluble substance that is condensation-polymerized in the absence of the water (e.g., hydrolyzable silane compound), the surface tension of the ink at 25° C. before the water-soluble substance is condensation-polymerized is set to 20–50 mN/m, or the ink further contains a fluoroalkyl monoalcohol whose boiling point is lower than 100° C.
摘要:
Ink for ink-jet recording contains an oil soluble dye, a humectant, a penetrant, water, and an amphiphilic star block polymer of which the outer portion is hydrophilic. The surface tension of the ink at 25° C. is in the range of 20 to 50 mN/m.
摘要:
Changes of ink properties are prevented in an ink jet recording head, an ink cartridge, and a recording apparatus which include ink containing a dye having an anion group, a humectant, a penetrant, water, and a hydrolyzable silane compound having an amino group. Resin or rubber which contains a hydrogen ion releasing additive is used for a member of the apparatus with which ink for ink jet recording comes in contact. The content of the additive in the material is not less than 0.001% by mass and not more than 0.1% by mass. The additive includes at least an acid, a ketone, and a functional group of ester each of which exhibits acidic properties.
摘要:
In an ink composition used for inkjet recording which contains a colorant, a humectant, water, and a water-soluble substance that begins to be condensation-polymerized as the water evaporates, a condensation-polymerization accelerating agent for accelerating the condensation-polymerization of the water-soluble substance is further contained.
摘要:
The invention has an object to provide an electronic paper file with high operating performance. The electronic paper file is assumed to comprises an electronic paper of an flexible display medium and a cover to which a plurality of electronic papers is attachable. In the invention, the first storage means stores display-data to be displayed on the electronic paper. The first display control means obtains from the first storage means the display-data corresponding to the desired page selected by the page selecting means and then display them on the electronic paper. Accordingly, even if the enormous pages of the electronic paper were not attached to the electronic paper file, the invention can display the whole of mass data such as an encyclopedia or theses data. Therefore, it is possible to improve the operating performance of the electronic paper file.
摘要:
An ink jet recording apparatus includes: a head body provided with a nozzle and a pressure chamber; an actuator including a piezoelectric element and an electrode for applying a voltage across the piezoelectric element; and a driving circuit for supplying a driving signal to the electrode of the actuator. The driving signal includes, in one printing cycle, a pulse signal applied with an interval that is shorter than a predetermined pulse interval being equal to a Helmholtz period of a head, and a pulse signal applied with an interval that is longer than the predetermined pulse interval.
摘要:
A piezoelectric actuator 21 has: a piezoelectric actuator part 22 made up of a common electrode 27, a piezoelectric element 29, and an individual electrode 33; an electrical interconnection joint part 43 formed on the individual electrode 33; an electrical interconnection 45 formed on the electrical interconnection joint part 43; a head block 47 fixed to a nozzle plate 39 through the electrical interconnection 45; and a PI tape 49 disposed within the head block 47. A closed space 57 is defined between the head block 47 and the nozzle plate 39. The closed space 57 is divided by the PI tape 49 into two sections. Of these two sections of the closed space 57, the one on the side of the head block 47 constitutes a first closed space 57a. A moisture absorbent 52 is sealed within the first closed space 57a. Relative humidity within the closed space 57 of the ink jet head 1 is not less than 0% nor more than 20%.
摘要:
A printer includes: a recording section for recording information on a recording medium; a medium carrying mechanism provided in an apparatus casing having an eject port that is opened in an upward direction or in a slanted upward direction; a medium accommodating section extending in a vertical or slanted vertical direction that defines a medium accommodating space that is continuous with the eject port; and an upward medium carrying mechanism that carries the recording medium upward by an amount according to the size of the recording medium stored in a size memory device, so that the re cording medium projects from the eject port by a predetermined constant length.
