摘要： To increase the size of dot printed on a print medium with an on-demand multi-nozzle ink jet head, at least two unit pulses are applied in succession to a piezoelectric element which varies the volume of an ink chamber. The unit pulse has a pulse width substantially equal to a period of Helmholtz natural oscillation determined based on dimensions, materials, and physical properties of an ink channel and the piezoelectric element and other components relating to oscillation. An off duration between adjacent unit pulses applied in succession to the piezoelectric element is preferably set one fifth to one fourth of the unit pulse width.

摘要： To eliminate influence of cross-talk in an on-demand multi-nozzle ink jet head, drive pulses to be applied to piezoelectric elements for driving nozzles aligned in a row are individually adjusted so that the nozzles eject ink droplets at the same speed when the nozzles are driven simultaneously. To the piezoelectric elements which are deactuated during printing, a dummy drive pulse having a voltage level in a range from 50 to 75% of a minimum voltage for ejecting an ink droplet is applied, whereby the ejection speed achieved when individual nozzles are driven approaches the ejection speed achieved when all nozzles are driven simultaneously. As such, the print quality is improved.

摘要： An on-demand multi-nozzle ink jet head includes a diaphragm and a plurality of piezoelectric stacks. The diaphragm forms at least one wall of a pressurizing chamber used to increase the pressure of the ink. When print signals are applied to the piezoelectric stacks. The stacks generate pressure fluctuations in the walls of the pressurizing chamber. An elastic material with adhesive properties is used to bond the diaphragm to the piezoelectric stacks, which elastic material has a Shore hardness of less than 80 on the A scale and less than 30 on the D scale.

摘要： A hot-melt type ink jet printer includes a nozzle array, an ink tank containing a hot-melt ink therein, and an ink supply tube connecting the ink tank and the nozzle array, wherein a hot-melt ink is used which is a solid at room temperature but liquifies when heated. The ink supply tube is made of an elastic material that contracts and deforms corresponding to contractions and deformations of the ink contained in the ink supply tube. A cap is attached to the tip end of the ink supply tube so that the inlet of the ink supply tube that is in the ink tank faces to the side or upward.

摘要： A print head for ink jet printer having a reduced length in a main scanning direction and an elongated length in an auxiliary scanning direction perpendicular to the main scanning direction. A plurality of linear print head modules are arrayed in the auxiliary scanning direction, and each linear print head module extends in a slanting direction with respect to the main scanning direction by a predetermined angle. Further, each linear print head module has a width in a direction perpendicular to its extending direction. The slanting angle and the width determine scanning pitch extending in the auxiliary scanning direction and can reduces the length of the print head in the main scanning direction.

摘要： A head arm for use in a magnetic disk drive, comprising a guide arm disposed between a magnetic head and an actuator so as to transmit actuating force of the actuator to the magnetic head thereby guiding the magnetic head along a plane of a magnetic disk, a printed circuit fixed to the guide arm, and deflection compensating member for making the coefficients of thermal expansion of said guide arm and said printed circuit substantially equal to each other in at least the direction of seek of the head arm. No thermal deformation in an out-of-plane direction occurs on such a head arm regardless of any variation in the temperature of the environment in which the magnetic disk drive is installed. A head arm may also comprise a guide arm and a printed circuit formed of a moisture absorptive material and covered at all or part of its surfaces with a covering layer formed of a moisture resistive material not permeable to moisture. No deformation in an out-of-plane direction occurs on such a head arm regardless of any variation in the humidity of the environment in which the magnetic disk drive is installed. Therefore, the possibility of occurrence of off-track can be minimized.
