摘要： PROBLEM TO BE SOLVED: To provide an ink jet head and an ink jet type recording device from which driving noise is hardly heard. SOLUTION: A piezoelectric actuator 21 is driven at frequency of 20 kHz or more by supplying an ink jet signal P1 or an ink non-jet signal P3 to the piezoelectric actuator 21 in an ink jet head 1. The ink non-jet signal P3 has a potential falling waveform S7 which has almost the same shape as a potential falling waveform S1 in the ink jet signal P1, and the same sound pressure SP is generated by the both signals. Continuation time of a potential maintaining waveform S8 is adjusted according to natural frequency of oscillation system in the piezoelectric actuator 21.

摘要： PROBLEM TO BE SOLVED: To obtain an image of high quality by gradation due to an area of a printing dot in an ink jet printer used as output machinery such as a computer. SOLUTION: Projected parts approaching each other are provided to two places of counter electrodes 22, 23. By this constitution, since two bubbles small in vol. can be generated at the same time, the speed of the volumetric change of bubles can be enhanced as compared with a conventional method and an emitting speed in such a case that emitted ink droplets are small is increased and the vol. of emitted ink droplets can be controlled over a wide range as compared with a conventional method and an image of high quality having high gradation properties can be obtained.

摘要： PROBLEM TO BE SOLVED: To stably perform the supply and flow of ink by irradiating nozzle orifices, a pressure chamber and the wall surfaces of ink passages with laser beam or plasma to modify the inner surfaces of them. SOLUTION: After a synthetic resin is electrodeposited on a nozzle plate 19, the synthetic resin is modified. Burr 23 is composed of a synthetic resin and protrudes to the leading end part of a nozzle orifice 14 to obstruct the emission of ink liquid droplets. An orifice leading end part modifying process is performed to remove the burr 23 formed to the leading end part of the nozzle orifice 14 to obtain the nozzle orifice 14 having an accurate shape coinciding with a plan, f The nozzle orifice 14, a pressure chamber and the wall surface of an ink passage, especially, the wall surfaces formed by the nozzle plate 19 in the pressure chamber and the ink passage are modified by excimer laser beam or oxygen plasma. By this constitution, the supply of ink is smoothly performed and excellent ink emitting control properties are obtained and printing of high quality becomes possible and the bonding strength of the nozzle plate and a substrate is excellent and durability is markedly enhanced.

摘要： PROBLEM TO BE SOLVED: To increase current density and to improve boiling bubble generation efficiency by passing current through conductive ink, boiling the ink between electrodes, generating bubbles, and making the apex angle of the opposite part of a pair of the electrodes which makes a nozzle installed in a part of a pressure chamber discharge ink droplets an isosceles triangle. SOLUTION: The tips of electrodes 13, 14 are suitably in a state which meets an isosceles triangle in which the apex angle of the tip part is 20-160 degree, in gradation printing of different dot diameters, since the alternating current I (t) density passing through conductive ink from the electrodes 13, 14 increases, and the generation efficiency of boiling bubbles 22 and the discharge efficiency of ink droplets increase so that the stable discharge of the ink and the curtailment of powder consumption can be attained. When the apex angle of the tip part exceeds 160 degree, the maximum temperature of the conductive ink between the electrodes 13, 14 is not a part A on the line of the shortest distance between the electrodes 13, 14 but is the end edge parts B of the electrodes 13, 14, when boiling bubbles 22 are generated, stable ink droplets can not obtained.
