  • Patent number: 9233532
    Abstract: 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.

  • Patent number: 8974029
    Abstract: An ink jet recording apparatus and printing control method are provided in which when a moving speed of a printing object is changed, a difference in writing start position is reduced and printing quality is improved. The apparatus includes an ink container, a nozzle connected to the container for ejecting ink, a charging electrode to charge the ejected ink, a deflecting electrode to deflect the charged ink, a gutter to collect ink not used for printing, a writing start timing control circuit to generate a first line clock signal, a printing width control circuit to generate a second line clock signal, and a control part. The control part controls print start timing based on the first clock signal, and when the printing object reaches the printing start timing, the control part performs a width adjustment of a character string of printing content based on the second clock signal.

  • Patent number: 6696953
    Abstract: Electronic article surveillance markers, methods for their production and for their use are disclosed. In one aspect there is provided an integrated deactivatable hybrid marker which can be used both in radio frequency and magnetic harmonic article surveillance systems. The harmonics generating element or elements of the marker are inserted into a RF resonant circuit as an active part of the circuit. The deactivation of the marker is accomplished by employing another element of high coercivity magnetic material. When placed in a RF interrogation field, the hybrid marker causes an increase in absorption of transmitted signal in order to reduce the signal in the receiving coil of the RF surveillance system. When placed in an interrogation zone of a magnetic harmonic article surveillance system, the marker generates high harmonics of the interrogating frequency that can be detected by the receiver of the surveillance system.
