  • Patent number: 8243337
    Abstract: For (CMYK) (x,y) data, a target-pixel checking unit calculates a target-pixel integrated value a(x,y) from CMYK binary data of a target pixel and a surrounding-pixel checking unit calculates a maximum surrounding pixel integrated value n(x,y) from respective CMYK binary data of surrounding pixels that are adjacent to the target pixel. Based on the target-pixel integrated value and the maximum surrounding pixel integrated value, a comparison determining unit estimates a higher toner pile height. The comparison determining unit adds transparent image data W(x,y) to the input data CMYK(x,y) and outputs output image data CMYKW(x,y) such that the toner pile heights become even.

  • Patent number: 8242747
    Abstract: In a charging control circuit for controlling charging of a secondary battery, a charging transistor generates a charging current according to a control signal input to a control electrode and outputs the charging current to the secondary battery. The proportional current generation transistor generates and outputs a proportional current proportional to the charging current output by the charging transistor. The constant current charging controller controls the charging transistor so that the proportional current generated by the proportional current generation transistor attains a predetermined first value. The constant current charging controller controls a voltage of a current output terminal of the proportional current generation transistor so that a voltage difference between the voltage of the current output terminal of the proportional current generation transistor and a voltage of a current output terminal of the charging transistor is maintained at a predetermined second value.

  • Patent number: 8233296
    Abstract: A front-end circuit of a power converter has a power connection wiring detecting circuit, a power switch and a control unit. The power connection wiring detecting circuit is connected to an AC power. The control unit is connected to the power connection wiring detecting circuit. The power switch is connected to the power loop. The control unit turns on or off the AC power loop through the power switch. When the power connection wiring is correctly connected with the AC power, the control unit turns on the power switch and the front-end circuit outputs the AC power to the back-end circuit. When the power connection wiring is incorrectly connected with the AC power, the control unit turns off the power switch and the AC power is not outputted to the back-end circuit.

  • Patent number: 8231201
    Abstract: In an inkjet recording device, ink droplets remaining on a nozzle surface are wiped off and the wiped off ink droplets are prevented from being scattered so as to stably form good quality images. When the wiper blade wiping the nozzle surface of the recording heads to wipe off the ink droplets and the like is separated from the nozzle surface and the bend of the wiper blade is straightened to restore to its idle position, a reaction force eliminating member absorbs the reaction force generated and softly restores the wiper blade to its idle position. As a result, the reaction force caused when the bend of the wiper blade is suddenly straightened is controlled, thereby preventing the ink drops and foreign matter on the header of the wiper blade from being scattered and avoiding the contamination of the inside of the inkjet recording device.
