摘要:
An ink containing a hydrophobic colloid charged with a positive zeta potential when the pH of the ink is within a range of over 4 and under 6. Silicon or silicon compound can be limited from being eluted into the ink from a circuit board formed from a silicon wafer or the like. Additionally, silicon or silicon compound, if eluted into the ink can be prevented from being deposited on a resistance heater and causing “cogation”, or to prevent the silicon or silicon compound from being deposited in an ink channel and nozzle to clog the nozzle.

A recording liquid contains a coloring matter, a solvent for dissolving or dispersing the coloring matter, and a nonionic surfactant, wherein the recording liquid has a foaming power of 0 mm to 50 mm and a foam stability of 0 mm to 50 mm, the foaming power and the foam stability being determined by substantially the same test method as that used to determine the foaming power and foam stability according to JIS-K3362. A liquid cartridge containing the recording liquid, a liquid ejection cartridge which ejects the recording liquid, a liquid ejection apparatus, and a liquid ejection method are also disclosed.

A head cartridge and a liquid ejection apparatus are provided in which cleaning performance of cleaning means is improved using a liquid absorbing force of a wiping member produced along with restoration of temporarily increased elastic displacement of the wiping member. An elastic displacement h (height of a projection) of a cleaning roller temporarily produced by the projection arranged at a position in the foreground of ink ejection nozzles in the cleaning direction of a nozzle surface is established to satisfy the following condition: h>(Vu/Vr)(L+n/2−φ/2),where the restoring speed of the elastic deformation of the cleaning roller is denoted as Vu; the moving speed of the cleaning roller is denoted as Vr; the movement distance of the cleaning roller from a restoring initiation point of the elastic deformation to the center of the liquid ejection nozzles is L; the contact width between the cleaning roller and the nozzle surface is n; and the diameter of the ink ejection nozzle is φ.

Disclosed is an ink liquid used in a printer device of the ink jet system for recording an image or letters/characters. A surfactant containing an organic compound represented by the following chemical formula 1: where m and n are integers not less than 1, is contained in an ink 2 to prevent blurring or bleeding from being produced at a point of deposition of an ink liquid droplet i.
摘要:
Since an ink (2) contains a hydrophobic colloid which will be charged with a positive zeta potential when the pH of the ink (2) is within a range of over 4 and under 6, it is possible to limit silicon or silicon compound from being eluted into the ink (2) from a circuit board (44) formed from a silicon wafer or the like. Thus, it is possible to prevent the silicon or silicon compound, if eluted into the ink (2), from being deposited on a resistance heater (48) and causing “cogation”, or to prevent the silicon or silicon compound from being deposited in an ink channel (42) and nozzle (45a) to clog the nozzle. Therefore, the ink (2) will not cause any non-spraying of the ink.

An ink for use in thermal inkjet recording contains a dye, water, and an organic phosphonic compound represented by the formula: Alternatively, an inkjet recording head may be treated with the organic phosphonic compound represented by formula (1) so that the surface of a heater device of the inkjet recording head is treated with the organic phosphonic compound represented by formula (1).
摘要:
A three-dimensional model, wherein coelom models such as blood vessels are stackingly molded based on tomogram data on a subject, the peripheries of the coelom models are surrounded by a three-dimensional model forming material, the three-dimensional model forming material is hardened, and the coelom models are fused or molten and removed, whereby a specified three-dimensional model can be formed.
摘要:
A method and apparatus for treating wastes by two-stage gasification recovers metals or ash content in the wastes in such a state that they can be recycled, and gases containing carbon monoxide (CO) and hydrogen gas (H2) for use as synthesis gas for ammonia (NH3) or production of hydrogen gas. The wastes are gasified in a fluidized-bed reactor at a low temperature. Then, gaseous material and char produced in the fluidized-bed reactor are introduced into a high-temperature combustor, and gasified at a high temperature and ash content is converted into molten slag. After water scrubbing and a CO conversion reaction, the gas is separated into H2 and residual gas. The residual gas is then supplied to the fluidized-bed reactor as a fluidizing gas.
摘要:
The present invention relates to a swirling-type melting furnace for gasifying combustible wastes and/or coal, and a method of gasifying wastes by the swirling-type melting furnace. In the swirling-type melting furnace (5), gaseous materials supplied to a combustion chamber (6) form a swirling flow which includes an outer swirling flow primarily containing particulate combustibles and an inner swirling flow primarily containing gaseous combustibles. Oxygen is supplied through an inner wall of the combustion chamber (6) to the outer swirling flow primarily containing the particulate combustibles for thereby accelerating gasification of the particulate combustibles.
