摘要:
A liquid supply device 10 is equipped with a liquid containing chamber 16, a transport tube 15 for sending the liquid inside the chamber 16 to a liquid jetting device 20, first and second members 171 and 172 sandwiching the tube 15, and a cam 173 that determines the position of the first member 171 relative to the second member 172. The tube 15 is equipped with an elastic portion 151 that elastically deforms and is flattened. In the first rotation position, the cam 173 arranges the first member 171 such that there is a space that allows the liquid to flow inside the part 151 between the first and second members 171, 172. In the second rotation position, the cam 173 arranges the first member 171 such that the elastic portion 151 is flattened by the first and second members 171, 172, and the liquid inside cannot flow.

摘要:
An A/D conversion circuit including a plurality of resistor elements connected in series between a low-potential power supply and a high-potential power supply. The A/D conversion circuit includes a plurality of comparators that compare a reference voltage divided by each of the resistor elements with an analog input voltage, the comparators having a sample-and-hold function for holding a sampled analog input voltage. The plurality of comparators also include a high-order bit comparator and a low-order bit comparator having different sampling sources. The high-order bit comparator may be configured to compare the analog input voltage and one of the reference voltages to obtain a determination result. The low-order bit comparator may old the analog voltage from the time that the low-order bit comparator retrieves the analog input voltage until the low-order bit comparator performs comparison.

摘要:
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.
