摘要： PURPOSE:To obtain good printing and to prevent the leakage of ink or the adhesion thereof to an unnecessary part by changing the ink supplied in a solid state to a liquid or high viscosity sticky state and adhering the ink to a plate selectively to print an object to be printed. CONSTITUTION:Fine granular solid ink 4 is stored in a developing device 3 and stirred by a developing brush 5 to be prevented from flocculation and charged frictionally to be attracted and applied to a plate 1 to form an ink layer 6. Next, when the ink layer 6 is irradiated with laser beam 7 in a pulse like state corresponding to printing data in the direction vertical to the rotary direction of the plate 1, the ink particles of the ink layer 6 of the irradiated part 8 are respectively melted mutually to be connected and become spot like liquid droplets 9 having a diameter almost equal to the irradiation diameter of the laser beam 7. Next, the liquid droplets 9 are transferred to the surface of a transfer drum 10 under pressure to be brought to transfer droplets 11 which are, in turn, transferred to the paper 12 moving in a direction 16 to form a printed image 14 using a fixing roller 13 and the unnecessary ink remaining on the transfer drum 10 is removed by a cleaner 15.

摘要： PURPOSE:To prevent the mixing of air bubbles or dust and to perform further stable injection, by arranging a filter in the container between an ink hole and an ink push-out part and storing ink between the ink hole and the filter. CONSTITUTION:A pipe 2, filter 3 and an ink push-out part 4 are arranged to a container 1 and the inside and outside of the container 1 are connected by the pipe 2 through an ink hole 5. The ink push-out part 4 is connected to the ink push-out core 6 connected to an ink push-out rod 7 and, by the ink push-out part 4 and the ink push-out core 6, the ink push-out core 6 and the ink push-out rod 7 or the combination of both of them, the degree of freedom of rotation, bending or slide is provided. Then, the leading end part of the pipe 2 is quietly immersed in an ink liquid. Next, when the ink push-out part 4 is moved while a grip 8 is quietly pulled, the generation of air bubbles are also eliminated.

摘要： PURPOSE:To obtain a sensible image having high resolution accurate to a magnetic latent image and high quality of printing without forming a block by bringing a magnetic liquid into contact while being fluidized as a means bringing a magnetic medium into contact. CONSTITUTION:An ink layer 7 shaped onto a spreading roller 6 in predetermined thickness is brought into contact and applied onto a magnetic drum 1 as being rotated by the spreading roller 6 in a developing machine 5 while the magnetic drum 1 is turned. A magnetic particulate toner group mixed into the ink layer 7 concentrically adheres to a magnetic latent image section, and forms clusters 11 and the toner group is changed into a sensible image at that time. An ink layer 7' spin-coated onto the magnetic drum 1 re-adheres on a remover roller 8 while a regular interval is kept at a removing point 10 by the remover roller 8 revolved in the direction of rotation 9 reverse to the magnetic drum 1. Flowing can be generated in the direction 12 in the ink layer 7' at that time, a magnetic particulate group shaping the clusters 11 on the magnetic drum 1 is held by the magnetic force of a magnetic latent image, and magnetic particulate groups except said group are scraped off by a blade 13 together with ink.

摘要： PURPOSE:To obtain extremely high response and to stably form a magnetic latent image by providing an avalanche effect or the avalanche effect and Schottky effect to a light control layer. CONSTITUTION:>=1 Kinds of films having the avalanche effect or the avalanche effect and Schottky varrier are used as the light control layer 4. More specifically, an adequate electrical bias is kept applied to the light control layer 4, then even if a small light quantity of light pulses for printing and recording are locally projected to said layer, the light projection current generated in the light control layer 4 is largely amplified by the avalanche effect and amplified current is locally passed to a magnetic layer 3 adjacent thereto, by which said layer is locally heated up to the Curie point or above. Demagnetization and magnetization inversion of the magnetic layer 3 are, therefore, easily and efficiently executed even with the light source of the small light quantity.

摘要： PURPOSE:To prevent the intake of air bubbles involved in an ink during the heating and cooling period by a method in which a local temperature regulator is provided to a head for solid ink-jet printer in such a way as to enable the directions of heating for melting and cooling for solidifying of solid ink to be controlled. CONSTITUTION:Heater plates 13-1-13-3 are divided by sheet electrodes 12, 12-1, 12-2, and 12-3 for heating solid ink for melting and set on the downside of a base plate 1 along the flow path 3 of the ink. The heater plates 13-1-13-3 are connected to a power source 15 by switches 14-1-14-3 in such a way as to enable their temperature to be controlled independently. An ink trap 17 is set on the ink supply side of the head, and ink 18 in solid state at ordinary temperature is heated to a temperature T6 by a heater block 19, a power source 20, and a switch 21 set below the ink trap 17 and kept in a low-viscous state. When the switches 14-1-14-3 are closed and the heater plates 13-1-13-3 are heated, the flow path 3 is heated and melted ink 22 becomes of a low viscosity for completing the preparation of printing.

摘要： PURPOSE:To obtain a photopolymer capable of being regulated in a change in properties such as dipole moment, wettability and absorption spectrum by the irradiation with light of a specified wavelength by reacting acid chloride groups as the side chain of a polymer with the amino or hydroxy groups of a photosensitive material. CONSTITUTION:A polymer containing acid chloride groups as the side chain (e.g. polyacryloyl chloride of a number-average molecular weight of about 1200000 and a degree of polymerization of about 13000) is reacted with a photosensitive amino or hydroxy compound comprising an azobenzene compound of general formula I (wherein X and Y are each H, F, Br, NO2, CN, CH3, C2H5 or CF3; and Z is NH2 or OH) (e.g. p-aminoazobenzene) or a spirobenzopyran of general formula II (wherein Z is NH2 or OH) to obtain a photopolymer containing azobenzene or spirobenzopyran as the side chain. When this compound is used as an image former of an image formation apparatus, a very clear and beautiful print can be obtained.

摘要： PURPOSE:To obtain an indole compound having photochromic properties and being stable in each isomeric form by nitrating a specified heterocyclic ring and reducing the ring. CONSTITUTION:An indole compound of formula I, wherein R1 to R12 may be the same or different and are each a group having at least one carbon atom, H or X (wherein X is F, Cl, Br or I). The indole compound can be obtained by nitrating a heterocyclic ring and reducing the ring. 3,3-Azobis(1,2- dimethylindole) as an example of the compound of formula I can be obtained by treating 1,2-dimethyl-3-nitroindole with ethanol, a sodium hydroxide solution and a zinc powder. The indole compound in the form of an isomer of formula I undergoes a structural change to form a compound of formula II by irradiation with light of a specified wavelength (lambda1), and the isomer of formula II is reconverted into the initial isomer by irradiation with a specified light of a specified wavelength (lambda2).

摘要： PURPOSE:To obtain a furan compound having photochromic properties and being stable in each isomeric form by reducing two specified nitro compounds. CONSTITUTION:A furan compound of formula III is obtained by reducing two nitro compounds of formulas I and II. In the formulas, R1 to R6 may be the same or different and are each a group having at least one carbon atom, H or X (wherein X is F, Cl, Br or I). The furan compound in the form of an isomer of formula II is converted into an isomer having a structure of formula IV by irradiation with light having a specified wavelength (lambda1). The isomer of the structure of formula IV is reconverted into an isomer of the initial structure by irradiation with light of a specified wavelength (lambda2). During this conversion, the compound does not undergo any change in molecular weight but undergoes a change in structure to cause a change in absorption wavelength. Namely, the furan compound of formula III has the so-called photochromic properties in which it reversibly changes its structure by irradiation with light, is thermally stable and is effective as a memory material.
