摘要:
A reaction apparatus is provided which comprises a flow control system provided with a convergent-divergent nozzle. This nozzle is operated under the optimum expansion condition, and the differential coefficient of the streamline of the channel inside the nozzle varies continuously and reaches zero at a throat of the nozzle.
摘要:
A device for blowing fine particles is provided which comprises a plural number of upstream chambers for jetting out fine particles provided against a movable substrate. Each of the upstream chambers may be provided with a gas exciter, and also may be provided with an energy imparter for imparting energy to the substrate.
摘要:
A molded composite material comprising a plural number of constituents is provided in which at least two of the constituents are distributed with a relative existing ratio varying at least in one direction in the composite material. A process for producing the composite material is also provided.
摘要:
Disclosed herein is a printing process in which at least two inks are applied to a cloth according to an ink-jet system to conduct printing, which comprises at least three steps of: (a) applying the two inks to the cloth in such a manner that at least a part of the inks overlaps each other; (b) subjecting the cloth, to which the inks have been applied, to a heat treatment; and (c) washing the heat-treated cloth, wherein the cloth is a cloth comprising fibers dyeable with disperse dyes, and each of the inks comprises a specified coloring matter, a compound for dispersing the coloring matter and an aqueous liquid medium.

Disclosed herein is an ink-jet printing process comprising the three steps of (a) applying inks containing a disperse dye, a compound for dispersing the disperse dye and an aqueous medium to a cloth comprising fibers dyeable with disperse dyes according to an ink-jet system (b) subjecting the cloth, to which the inks have been applied, to a heat treatment and (c) cleaning the heat-treated cloth, wherein the inks comprise two or more inks which separately contain disperse dyes of the same hue and are different in dye concentration, and the thermal diffusivity of the disperse dye used in the ink having a low dye concentration is higher than that of the disperse dye used in the ink having a high dye concentration.
摘要:
An ink absorbent member is prepared for holding an ink stored in an ink storing section in an ink jet cartridge. The ink absorbent member contains not more then 0.20% by weight, on the basis of the member, of a fraction of soluble matters in a liquid containing an organic polar solvent incapable of reacting with the ink absorbent member such as monohydric alcohols or alkyl ethers of polyhydric alcohols.
摘要:
A medium for image formation which comprises a monomolecular film or monomolecular built-up film of a metal chelate compound and a process for image formation which comprises (1) manipulating the adsorption of a gas on a metal chelate compound and the desorption of the gas therefrom or (2) reducing metal ions in molecules of a metal chelate compound.
摘要:
An optical element comprised a pair of plates between which an optical modulation liquid layer is sandwiched, the optical modulation liquid layer exhibiting a light scattering property caused by suspension of fine particle polymer when not heated and exhibiting transparency caused by dissolution of fine particle polymer when heated, the change of such light scattering property to transparency being reversible.
