摘要： PURPOSE: To prevent stray current corrosion breakage in a heater by specifying an ink channel height and an overlap of vertical projection images and by an electrical insulation coating treatment which thermally oxidizes the surface of a thin-film resistor at high temperature. CONSTITUTION: An ink discharge nozzle 12 is of a straight cylinder, a structure that makes images vertically projected to a heating resistor 3 at the bottom overlap within 5μm, the height of a bulkhead 8 is 30μm or less. Thus vacuum bubbles are prevented from disappearing. A SiO2 insulation layer 17 is provided on a silicon substrate 1, and a Ta-Si-SiO alloy thin film resistor 3 excelling in pulse-resistance and oxidation resistance and a discrete Ni metal thin film conductor 4, and a common Ni metal thin film conductor 5 are formed thereon. The surface of the thin film resistor 3 is given electrical insulation coating by high temperature thermal oxidation. In this case, to prevent the metal thin film conductor 4 like Ni from being oxidized, a thermal oxidation treatment is made by heating only the resistor up to about 550 to 600 deg.C by pulse energization of the alloy thin film resistor 3.

摘要： PURPOSE: To reduce the size of a printer, through cooperation of an assembly comprising a variable volume chamber and a valve and an assembly for constituting an ink and solvent reservoir of a constricted part and a variable volume chamber which drives with an eccentric wheel having a pressure sensor being coupled through a valve. CONSTITUTION: Variable volume chambers 1, 23 detect the volume periodically through an eccentric wheel 3 coupled with a motor 4 rotating at a constant speed. The rotation cycle includes a stop interval required for static pressure measurement through a pressure sensor 5 at every revolution. When a jet 21 is delivered by opening a valve 19, although the volume of ink 34 under pressure of air 180 in the reservoir 18 decreases with time to cause pressure drop, since the pressure is sustained and thereby the volume of ink is sustained, the variable volume chamber 1 and valves 7, 9 function as pump to sample ink 33 in a reservoir 17 and provides it to the reservoir 18. During this interval, pressure is measured by means of the pressure sensor 5, and when the reservoir 17 is empty and the pressure is deficient, the valves 7, 9 and 13 are used sequentially.

摘要： PURPOSE:To form a flow of no pulsation in a circulating path and to provide no dead space, so that a fine amount of liquid can be allowed to accurately flow, by giving energy to liquid exposed from an outlet part of the circulating path so as to continuously vaporize the liquid. CONSTITUTION:A liquid reservoir part 2 for accumulating liquid is connected to one side of a fine circulating path 1, to form the other side to serve as an outlet part 3 of an opening. Relating to a pressure by a level of liquid in the liquid reservoir part 2, internal resistance of the circulating path 1 and surface tension of a liquid surface exposed to the outside in the outlet part 3 are balanced, to place a flow in a stationary condition. Now when vaporizing energy is given to the liquid exposed in the outside in the outlet part 3, the liquid in the outlet part 3 is vaporized to become vaporized matter 4 and released. Then by a vaporized amount, the liquid is supplied by a capillary phenomenon to flow in the outlet part 3 through the circulating path 1. Now when the vaporizing energy is continuously given to continue vaporization, a flow of no pulsation can be formed in the circulating path 1.

摘要： PURPOSE:To simplify the constitution, miniaturize the apparatus and reduce the power consumption by a method wherein, an electric power is conducted from an electrode to a electric resistance part of a film thereby making ink and feeding the melted ink into a penetrated hole. CONSTITUTION:An image forming film 21 having a plurality of penetrated holes 22 is formed by a film the whole body of which consists of electric resistant member, further it is constituted to travel while making contact with a thermal head 3, while a roller 23 which makes a film 21 pressed against an ink feeder 7 is arranged in the vicinity of an injector for liquid state heat-melted ink 12a, while heating electrode at both side rims. By energizing the film 21 from the heating electrodes 24, 25, a solid form 12 to be melted by heat is formed into a liquid ink 12a, which is fed into the penetration hole 22.

摘要： PURPOSE:To obtain a small-sized high speed recorder having a simple structure and easiness for lining by using conductive wax ink and incorporating a heat source for melting ink in an ink supply roller. CONSTITUTION:An electrode 1 is buried linearly with metal at a pitch of 140mum on the surface of a platen 6. When an electric field of a power source 5 is not operated between conductive wax ink 8 and the electrode 1, the surface tension of the ink 8 is regulated. Thus, ink supplied to a retainer 2 cannot advance into a hole 3, and the ink does not arrive at a recording sheet 7. A voltage is applied between the ink 8 and the electrode 1 with the electrodes 5 at the time of recording to generate an electric field. Thus, the ink 8 is passed through the hole 3 by electrostatic force operating thereby to be adhered to the sheet 7. Thus, since a recording can be conducted merely by operating the electric field at the ink 8 and passing through the hole, its structure is simple, and can be lined to realize a small-sized high speed printer.
