摘要： PROBLEM TO BE SOLVED: To provide a method and an apparatus for producing particles having modified surfaces which enable the production of the particles each having a modified surface and a comparatively small and uniform particle diameter by a simple apparatus and operation in a short time at a low cost. SOLUTION: First a suspension is prepared by suspending solid particles in a liquid in a droplet production and electrofication section 2, secondly droplets are formed by spraying the suspension and the droplets are made to be electrically charged by at least one needle electrode applied with a high voltage, and thereafter the charged droplets are introduced into a modification section 4 through a droplet-feeding section 3 in order to vaporize the liquid in the droplets. Thus, a charged quantity of a liquid molecule is increased to cleave the bond of the liquid molecular and the liquid molecule where the bond is cleaved reacts with the surface of the solid particle, thereby it is possible to introduce at least one substituent on the surface of the solid particle and to chemically modify the particle.

摘要： PROBLEM TO BE SOLVED: To provide a production process for hydrophilic particles that can stably hydrophilizing hydrophobic substance in excellent reproducibility and a production process for hydrophilic particles from pigment without occurrence of color change before and after the hydrophilization treatment. SOLUTION: The apparatus for producing hydrophilic particles is equipped with the sprayer 10 that inject the solution 14 prepared by dissolving the hydrophobic substance in an acidic solution (including at least sulfuric acid and chlorosulfonic acid at a volume ratio of 20/1-1/20) and with the mixing zone 22b in which the liquid particles formed in the sprayer 10 are exposed to super- saturated steam to allow water to condense on the surface of the liquid particles. The hydrophobic substance gets hydrophilic, when it is dissolved in the acidic solution. Super-saturated steam condenses into water particles around the liquid particles and mix with the solution, when it comes into contact with the liquid particles, resultantly the solution is diluted. Consequently the hydrophilic substance dissolved in the acidic solution is precipitated out as the objective hydrophilic particles.

摘要： PROBLEM TO BE SOLVED: To disperse spacers with certainty in a desired area of a liq. crystal display element by a highly versatile method. SOLUTION: A read-out member 2 successively read out the array pattern of the black matrix of a liq. crystal display element L brought into a production device 1. When the liq. crystal display element L passes under a counter electrode 5, voltage is applied to electrodes 4a... of a powder control member 4 selected on the basis of information relating to the array pattern fed back from the read-out member 2, and spacers supplied from a powder electrifier 3 fly toward the liq. crystal display element L and are adsorbed there. By controlling the flight of the spacers on the basis of the read-out information on the array pattern synchronously with the transit of a certain array pattern under the counter electrode 5, the spacers can be exactly dispersed on the black matrix.

摘要： PROBLEM TO BE SOLVED: To provide a direct recording imaging system in which developer can be charged and fed stably. SOLUTION: In the developer charger 16 of the imaging system 1, ions generated from ion generating sections 14,... are irradiated, as an ion flow F, to the developer reservoir 13 at a developer supply section 15. Developer charged by the ion flow F ascends as a cloud and reaches a flight control section 18. A voltage corresponding to image information is then applied to each gate 18a at the flight control section 18 and the developer passed through the gate 18a flies to the counter electrode 19 side through a field formed between the gate 18a and the counter electrode 19 where the developer adheres onto a recording medium S carried from resist rollers 5, 5 to form a developer image. Subsequently, the recording medium S is carried to a fixing section 3 and passed between a pressure roller 11 and a heat roller 10 while being clamped and the developer image is hot pressed and fixed.

摘要： PROBLEM TO BE SOLVED: To provide a production method of particulates coated with resin capable of easily producing high performance/high quality particulates coated with the resin by efficiently executing the supplying and mixing of a raw material and the recovering of the formed particulates coated with the resin and to provide a production device used therefor. SOLUTION: For example, at least either one among a shape, a supply condition and a transport condition of a droplet as an intermediate formed at a particles supply part 10 and containing particulates (particulates) is detected by a state detecting part 40 as a particle state. The obtained detected result is used for controlling a particulates supply source 11 forming the droplet. In this way, the droplet is formed more surely and the particulates coated with the resin is more surely produced as well. A plurality of state detecting parts 40 are provided preferably.

摘要： PROBLEM TO BE SOLVED: To obtain a recording solution having a small and uniform particle diameter, capable of exhibiting excellent dissolution stability and dispersion stability by a simple apparatus and an easy operation in a short time by retaining pigment particles subjected to a specific surface treatment in a solvent containing water. SOLUTION: This recording solution retains pigment particles having 10-20 nm average particle diameter in a water-containing solvent (preferably water). The pigment particles are provided with an oxidation treatment part on the surface. Plural pigment particles having mutually different sizes are preferably used as the pigment particles. The oxidation treatment part is preferably formed on the surface of the pigment particles by suspending the pigment particles in an acidic solution to give a suspension, heating the suspension so as to subject the acidic solution to nucleate boiling by the use of the pigment particles as a nucleus. Preferably the recording solution further contains an alkylene glycol as a wetting agent. Consequently the recording solution to be suitably used for a ball-point pen and a marking pen can be provided.

摘要： PROBLEM TO BE SOLVED: To obtain modified ink particles having satisfactory heat resistance, solvent resistance, resolution, and ink jet characteristics and capable of preventing the occurrence of pinholes, etc., by forming, on at least a part of the surfaces of ink particle bodies, a modified layer by depositing the vapor of a modifier on the surfaces of ink particle bodies being floating. SOLUTION: When the ink particle body 22 is hydrophilic like in the case of a color particle for a color filter of a liq. crystal panel, the modified layer 57 is pref. hydrophobic. When the ink particle body 22 is hydrophobic like in the case of a carbon black for a black matrix, the modified layer 57 pref. has a hydrophilicity, e.g. a hydrophilicity based on carboxy groups formed by the oxidation with nitric acid. The modified ink particles can be prepd. by floating ink particle bodies and depositing the vapor of a modifier onto the surfaces of the bodies to form a modified layer on the surfaces of the bodies. Thus, a color filter can be easily produced.

摘要： PROBLEM TO BE SOLVED: To provide a surface modification method whereby a surface-modifying polymer film can be formed on the surfaces of particles in a short time with a simple apparatus by an easy operation without electrostatically charging the particles and provide surface-modified particles produced by forming a surface-modifying polymer film on the surfaces of particles. SOLUTION: A first monomer component is incorporated into particles of which the surfaces are to be modified; and the particles are then brought into contact with the supersatd. vapor of a second monomer component to condense this monomer component on the surfaces of the particles. Thus, the two monomer components are copolymerized to form a polymer film on the surfaces. By this method, surface-modified particles having a polymer coating film formed on the surfaces are obtd. more efficiently than by a conventional method.
