摘要： PURPOSE:To enable an ink sheet to be used repeatedly by sticking a charge-injected conductive ink on an intermediate roller, thereafter by supplying the insulating layer side of the ink sheet with electric charge, and by replenishing the transfer part of the ink layer of the ink sheet with the conductive ink through an electrostatic force from the intermediate roller. CONSTITUTION:When a conductive ink 7 packed in a hopper 6 is supplied to the space between an intermediate roller 3 and a first electrode 5a and voltage V is applied between the conductive layer 2 of the intermediate roller 3 and the first electrode 5a by a power supply 8a, an electrically continuous path is formed in the conductive ink existing in said space and electric charge (q) is injected into the conductive ink 7 in contact with the dielectric layer 2 of the intermediate roller 3. However, the conductive ink 7 on said ink 7 merely forms the electrically continuous path of the electric charge and holds no electric charge. Therefore, only the conductive ink 7 in contact with the intermediate roller 3 can be stuck in a thin layer on the intermediate roller 3 by an electrostatic force. Accordingly, the conductive ink 7 can be selectively stuck only on the insulating part 11b of the ink sheet 12 to replenish the part and is fixed by fixing means as occasion demands so that the ink sheet 12 is refreshed.

摘要： PURPOSE:To make an ink sheet reproducible, by supplying conductive ink onto said ink sheet including a dielectric layer and an ink layer having electrical conductivity formed on said dielectric layer and by supplementing the transfer part of said ink layer with said conductive ink. CONSTITUTION:An electrode 11 is arranged on the side of the ink layer 3 having electrical conductivity of an ink sheet 1, a counter electrode 12 is placed on the side opposite to said ink layer 3 side so as to come into contact with the base layer 2 serving also as a dielectric layer of said ink layer 1, and a voltage supply source 13 applying bias voltage Vb is arranged between both electrodes. Conductive ink 15 is held on the electrode 11 rotating in the direction of the arrow 14 and supplied onto the ink sheet 1. When said bias voltage Vb is applied thereto, said conductive ink 15 adheres to the transfer part 9 of said ink layer 3 having electrical conductivity. At the time of coming into contact with the adhering part 8 of said ink layer having electrical conductivity, then, said conductive ink 15 releases electric current applied thereto in the ink layer 3 having electrical conductivity and remains bound to the electrode 11. Therefore, the conductive ink 15 adheres to the transfer part 9 only of said ink layer 3 having electrical conductivity of the ink sheet 1.

摘要： PURPOSE:To obtain strong flying force of ink and to avoid clogging of a nozzle, by providing a magnetic coil. CONSTITUTION:A magnetic field generating means is provided which consists of an electromagnetic oil 1 and yokes 2, 2'. Ink is made flying with the use of the attraction force and repulsive force of magnetism. In other words, direct current is fed in the electromagnetic coil 1, so that magnetic poles are generated at yokes 2, 2'. At this time, ink is drawn to the side of the yoke 2, that is, to pole N by a soft-magnetic thin film 24 on an elastic body 4. This state in an initial state. When ink is allowed to fly, an outside voltage is applied to a magnetic coil 22 in the form of pulses so that pole (n) is generated in the magnetic coil 22 of the elastic body 4 at the opposite side to a base plate 21. Then, the elastic body 4 is displaced by the magnetic repulsion, thereby to fly the ink 5. Thereafter, the outside voltage is stopped to be applied or applied so as to have a reverse polarity, whereby magnetic attraction force is produced to return the state to the initial state.

摘要： PURPOSE:To eliminate an exposing and forming process and to miniaturize the title device by impressing a prescribed voltage between conductive powder and plural electrode heads, pouring electric charges into the conductive powder from a member supporting said powder and forming an image on an image forming member. CONSTITUTION:Rollers 6 and 6' keep the surface potential of the image forming member 5 constant to prevent base fogging. The electrode head 8 is structured to arrange plural divided electrodes 81 on an insulating substrate 80 in a strip and all parts other than a part coming into contact with the image forming member 5 are insulated by an insulating layer 82, and driven by a driver IC 83. To form an image on the image forming member 5, a negative voltage is impressed on each electrode with respect to the conductive powder 1, and when no image is formed, each electrode is brought into the same potential as that of the conductive powder 1. Then, the image forming member 5 and the image forming member 10 are overlapped correctly and passed by a fixing device 9 as they are, thereby transferring an image onto the image forming member 10. In such a way, the exposing and forming process is eliminated to miniaturize the device.

摘要： PURPOSE:To enable a powdery ink to be adhered only to parts deprived of an ink layer, selectively and with favorable reproducibility, by applying a bias voltage between a first and a second electrode, and supplying the powdery ink comprising substantially the same components as those of an ink layer to a space between the ink layer and the second electrode. CONSTITUTION:A first electrode 7 is disposed to make contact with an insulating part 2 of an ink sheet 1, whereas a conductive sleeve 8 as a second electrode is disposed at a position spaced from a conductive ink layer 3, and a voltage supply source 9 capable of applying a bias voltage between the electrode 7 and a conductive sleeve is provided. A powdery ink 10 comprising substantially the same components as those of the ink layer is supplied between the ink layer 3 and the sleeve 8, and a multi-pole magnet 11 is provided for holding the ink 10 on the sleeve 8, which is rotated in the direction of an arrow 12. The ink 10 makes contact with the ink sheet 1, is subjected to injection of an electric charge by the bias voltage, and is adhered to dropouts 4 of the ink layer. On the other hand, the ink which makes contact with deposits 5 of the ink layer or with the ink adhered to the parts 4 releases the injected charge, and is therefore not adhered.

摘要： PURPOSE:To regenerate an ink sheet with a low power consumption, by providing an ink sheet with an insulating layer and a conductive ink layer, and providing a means for sequentially supplying a powdery ink comprising substantially the same components as those of the ink layer onto the ink sheet under application of a bias voltage. CONSTITUTION:An ink sheet 1, provided in a loop form and comprising a conductive ink layer 3 on an insulating layer 2, is fed in the direction of an arrow 4. Printing on a recording medium 7 is conducted by a thermal head 5, resulting in that parts 8 from which the ink layer is transferred and parts 9 from which the ink layer is not transferred are formed on the ink sheet 1. A powdery ink 10 comprising substantially the same components as those of the ink layer 3 is reserved in a hopper 11, and is sequentially supplied onto the ink sheet 1 by a magnetic sleeve 13. The magnetic sleeve 13 and a bias roller 14 are disposed on opposite sides of the ink sheet 1, and a bias voltage 15 is applied therebetween. The ink 10 making contact with the parts 8 from which the ink layer is transferred is subjected to injection of an electric charge, and is adhered to the parts 8. To fix the ink 10 onto the insulating layer, the ink sheet 1 is passed between heated rollers 16.

摘要： PURPOSE:To obtain an ink sheet which can be reused through regeneration, by incorporating a magnetic material into an ink layer of an ink sheet. CONSTITUTION:An ink layer 2 comprising a magnetic material is provided on a base 1 of an ink sheet 4. A first electrode 13 is disposed to make contact with the base 1 of the ink sheet 4, and a magnetic sleeve 14 incorporating a multi-pole magnet therein is disposed opposite to the electrode 13, with the ink sheet 4 therebetween. A bias voltage 15 is applied between the electrode 13 and the sleeve 14. The magnetic sleeve 14, by which a powdery ink 16 comprising substantially the same components as those of the ink layer is sequentially supplied between the sleeve 14 and the ink sheet 4, is rotated in the direction of an arrow 17. The ink 16 making contact with parts 10 deprived of the ink layer 2 by recording is adhered to the ink sheet 4 due to a difference in capacity or by injection of an electric charge, whereas the ink 16 making contact with parts 11 not deprived of the ink layer of the ink sheet 4 is not adhered to the ink sheet 4. The particulate ink is adhered selectively to only the parts deprived of the ink layer 2 due to recording, and the adhered ink is fixed onto the ink sheet 4 through melting by heated rollers 18.

摘要： PURPOSE:To minimize the temperature deterioration in basic optical characteristics of a solid-state image pickup element for cutting down the cost by a method wherein a transparent sheet with thermal expansion coefficient lower than that decided by the thermal expansion coefficient of another transparent sheet whereon a photoelectric conversion element is formed and that of a transparent mounting substrate is held to be bonded between the transparent insulating sheet and the transparent mounting substrate. CONSTITUTION:A photoelectric conversion element or driving element 11 thereof is formed on a transparent insulating sheet 12 which is generally made of low expansion non-alkali glass because the driving element 11 is required of high temperature semiconductor processing as well as fine processing with the precision not exeeding micron order. Such a glass, being expensive, is hardly applicable to a transparent mounting substrate 16 in view of the larger size and resultant higher price. Therefore, the thermal stress is relieved by bonding another transparent sheet 14 with thermal expansion coefficient not exceeding 2(a+b)/3 to the space between the transparent insulating sheet 12 [with thermal expansion coefficient of (a)] whereon the photoelectric conversion element 11 is formed and the transparent mounting substrate 17 with [thermal expansion coefficient of (b)]. Through these procedures, the transparent insulating sheet 12 can be made much smaller and thinner than the transparent mounting substrate 16 at low cost. Besides, the bonding agents 13 (1) and 15 (2) can either be equivalet or different from each other.
