    摘要： In an ink-jet recording apparatus, insoluble materials originating from rubber members employed in an ink passage are prevented from precipitating into a preservation solution or a water-based ink filled into the ink passage. The ink-jet recording apparatus in which the preservation solution or a water-based ink is filled into the ink passage, is configured such that a rubber member employed in the ink passage is formed of a rubber not containing a lubricant.

    摘要： An ink-jet recording apparatus has an ink passage into which a water-based ink or a preservation solution is filled. The ink passage employs a rubber member formed from a rubber in which a butyl rubber polymer serving as a base polymer, zinc oxide serving as a vulcanization agent, and a thiourea-based compound serving as a vulcanization accelerator are employed. Each of the water-based ink and the preservation solution comprises water and a water-soluble organic solvent. The ink and the preservation solution contain water in an amount of 70 wt. % to about 85 wt. % with respect to the total weight of the water-based ink and the preservation solution, respectively.

    摘要： The ink-jet recording apparatus has an ink passage into which a water-based ink or a preservation solution is filled. The ink passage employs a rubber member formed from a rubber in which a butyl rubber polymer serving as a base polymer, zinc oxide serving as a vulcanization agent and a thiazole-based compound serving as a vulcanization accelerator are employed. The water-based ink includes at least a coloring agent, water and a glycol ether, an amount of the glycol ether being about 5 wt. % to about 10 wt. % with respect to the total weight of the water-based ink. The preservation solution includes at least water and a glycol ether, an amount of the glycol ether being about 5 wt. % to about 10 wt. % with respect to the total weight of the preservation solution.

    摘要： Embodiments of the present invention allow for a precise altitude to be calculated from read-out signals of a head slider. In one embodiment, a hard disk controller/multiprocessing unit (HDC/MPU) determines a head element portion in which the instability has occurred in accordance with the resolution change. The HDC/MPU adjusts the clearance accordingly. The head element portion reads signals of different frequencies under a condition of the signal strengths coinciding with a reference value, and the HDC/MPU calculates the resolution. The HDC/MPU determines that the instability has occurred if the difference is outside the criterion. The HDC/MPU uses the read-out signal of a head slider in which the instability has not occurred to calculate the altitude.

    摘要： A water base ink set for ink-jet recording includes a water base ink which contains an acid dye, and a water base ink which contains a basic dye. The water base ink contains a polymer which has an average molecular weight of 3,000 to 20,000 and which is represented by the following formula (1): wherein X represents H or COONa, and Y represents H, COONa, SO3Na, or CH2OR in the formula (1). R represents a substituted group having SO3Na with carbon atom or atoms of a number of 1 to 5. When the ink containing the acid dye and the ink containing the basic dye are mixed with each other, then the head discharge section is prevented from any clog-up, and it is possible to perform the stable jetting operation.
