  • Publication number: 20110074994
    Abstract: In a reference signal comparison AD conversion scheme, a reference signal SLP_ADC and each of P and D phases of a pixel signal voltage Vx are compared. A count clock CKcnt1 is counted based on the comparison result. The counting result data is converted into signal data Dsig, i.e., the difference between the P and D phases, which is also subjected to CDS. At this time, the n-bit AD conversion is performed on each of the P and D phases of the pixel signal voltage Vx, followed by summation for digital integration. This prevents any possible detrimental effects that may be caused by summation in the analog domain. Although the signal data becomes W times greater, noise will likely become ?W times greater. This alleviates the problem of random noise resulting from AD conversion such as quantizing noise and circuit noise that do not exist in the analog domain, thus reducing the noise.

  • Patent number: 6540346
    Abstract: A color filter manufacturing apparatus can manufacture a color filter with less color unevenness in a short period of time. The color filter manufacturing apparatus forms an array of colored portions of a color filter by discharging a plurality of inks from a plurality of discharge orifices at a predetermined density by using an ink-jet head having a plurality of discharge orifices, an ink chamber connected to the plurality of discharge orifices, an ink supply opening for supplying ink to the ink chamber, and an ink exit opening for exiting ink from the ink chamber. The color filter manufacturing apparatus comprises an ink flow generating device for generating a flow of ink from the ink supply opening to the ink exit opening in the ink chamber while discharging ink from the discharge orifices for coloring. The colored portions are formed when a variation rate of ink volume discharged from the plurality of discharge orifices for forming the array of colored portions is ±3% or less.

  • Patent number: 4014509
    Abstract: A proportional electromagnetic-type direction-and throttle-controlling valve comprising a spring centered valve spool in a valve body, a pressure reducing valve, two flow restricting orifices, two DC solenoid controlled poppet valves and a vent port in each pressure chamber. Supply flow reduced to a fixed low pressure is divided into two branch lines with flow restricting orifices. The pilot pressure in each restricted flow passage with vent port is controlled by a DC solenoid-controlled poppet valve. The pilot pressure acting on the main spool end moves the spool against the spool centering spring force proportionally to the input DC current. Therefore, the flow rate through the throttling gap between the spool land and the mating valve body is controlled proportionally to input DC current. Vent ports are provided for rapid action of the spool.
