摘要： In an ink jet serial printer, a drop collector has horizontal and vertical collector sections or gutters. Unused drops are diverted in the direction of motion during uniform velocity of the ink jet head into the vertical section and into the horizontal section during acceleration/deceleration portions of head motion. A bias potential applied to the vertical drop deflector is removed during acceleration/deceleration to cause unused drops to be directed to the horizontal collector section.

摘要： One or more magnetic fields having non-uniform gradients is periodically applied to a magnetic liquid stream, which is preferably isotropic and virtually free of remanence, to create perturbations in the stream so as to form droplets therefrom with substantially uniform spacing and of substantially uniform size. If more than one of the magnetic fields is applied, the maximum strength of each field is spaced an integral multiple wave length from the maximum strength of the adjacent magnetic field with each magnetic field having substantially the same maximum strength. The wave length of the perturbation is preferably between 4d and 8d where d is the diameter of the stream.

摘要： BECAUSE OF THE FAIRLY CLOSE SPACING BETWEEN INK DROPS WHICH IS USED IN THE PROCESS INK DROP PRINTING, THERE ARISES A PHENOMENON OF REPULSION BETWEEN ADJACENT DROPS WHICH HAVE SIMILAR CHARGES ON THEM, WHICH CAUSES FAULTY PRINTING. THIS IS OVERCOME BY PROVIDING GUARD DROPS BETWEEN THE CHARGED DROPS WHICH ACT AS A SHIELD TO MINIMIZE THE ADVERSE AFFECTS OF DROP CHARGE REPULSION.

摘要： A method for enabling marking of a pattern on a substrate with an industrial printer includes executing a genetic algorithm based on the pattern to be marked on the substrate. A result of the genetic algorithm indicates a resulting path which the industrial printer should follow when marking the pattern on the substrate. It is determined if the resulting path fulfills at least one criterion of: the resulting path matches an optimal path for marking the pattern, the resulting path substantially matches the optimal path, or a time spent for executing the genetic algorithm has reached or exceeded a threshold.

摘要： Under a condition in which bowed printing occurs, a horizontal shift is suppressed to improve print quality. Following a program stored in a ROM 12, an MPU 10 generates video data for charging print particles according to print contents data stored in a RAM 11. Based on the print contents data, the MPU 10 detects a letter to be printed last, and when the letter to be printed last is printed to end a print operation, generates video data so that based on the video data, a non-print charge voltage driving non-print particles to an extent that they do not fly over a gutter 25 is applied to non-print particles. The number of the non-print particles subjected to the non-print charge voltage is determined by the MPU 10, based on the distance from a print head 2 to a print subject 30, a letter height preset value, etc. A character signal generating circuit 18 generates the non-print charge voltage, based on the video data, and applies the generated the non-print charge voltage to a charging electrode 22.

摘要： Provided is an inkjet recording device for performing print control by increasing or decreasing the number of adjustment ink particles, which are used according to the speed of the object being printed even when the movement speed of the object being printed is increasing or decreasing and which are uncharged particles carrying a fixed electrical charge that takes electrostatic bonding into consideration. The present invention is an inkjet recording device provided with an ink container for holding ink that is to be printed on the object being printed, a nozzle that is connected to the ink container and discharges the ink, a charging electrode for charging specified ink that has been discharged from the nozzle, a deflecting electrode for deflecting the ink charged by said charging electrode, a gutter for collecting the ink that is not used for printing, and a control unit for controlling the printing. The inkjet recording device is characterized in that the control unit performs control so that ink particles which are not used for printing and are adjacent to ink particles that are used for printing are charged by the charging electrode.

摘要： In order to provide a liquid ejection head which enables ejection of a droplet at a higher frequency, according to the invention, a piezoelectric vibrator has a multilayer structure. In the multilayer structure, an upper piezoelectric layer and a lower piezoelectric layer are laminated one on another. A drive electrode is formed at a boundary between the upper piezoelectric layer and the lower piezoelectric layer and is electrically connected to a source for supplying a drive signal. An upper common electrode is formed on the surface of the upper piezoelectric layer. A lower common electrode is formed on the surface of the lower piezoelectric layer. An inertance of a nozzle orifice and an inertance of an ink supply port are set so as to become greater than an inertance of a pressure generating portion.
