    Patent number: 8736541
    Abstract: A liquid crystal display (LCD) device's microcontroller is used drive an LCD lamp ballast such that the scrolling effect from its light leakage may be reduced to a visually imperceptible level. A check may be performed of lamp's control status in order to verify the microcontroller's ability to properly and accurately control the lamp ballast. The microcontroller may then determine a frequency and duty cycle to use for the microcontroller's PWM control signal. Thereafter, the microcontroller may generate the PWM control signal in accordance with the determined frequency and duty cycle, and drive the lamp ballast using the control signal.

  • Ink jet recording apparatus
    Patent number: 8646885
    Abstract: A tube support member that puts a tube connected to an ink jet head and an ink tank in a bent state is provided. Accordingly, when a pulling force acts between the bent support member and the tube, a component force acting as contact force occurs at the surface that makes contact with the tube, and a high degree of friction is generated in response to this component force. The tube is thus strongly supported in a state in which the tube does not shift with the dimensions of the tube changing. Meanwhile, when the pulling force is released, the component force is also eliminated, and the tube is freed; the dimensions of the tube return to normal, and the tension is eliminated.

    Abstract: A printing apparatus includes a head which discharges color inks and into which clear ink that prevents the head from being clogged and white ink are selectively filled. A selection portion communicates either of a white or a clear ink container with the head. A controller executes a first switching from a second filled state where the head is filled with clear ink to a first filled state where the head is filled with white ink by shifting from a state where the clear ink container is communicated with the head to a state where the white ink container is communicated with the head. A second switching is executed from the first filled state to the second filled state by shifting from a state where the white ink container is communicated with the head to a state where the clear ink container is communicated with the head.
