Abstract: An ink jet printhead control circuit is provided. The ink jet printhead control circuit includes at least a nozzle firing circuit and a nozzle firing control circuit. The nozzle firing circuit includes a switch and a heating resistor. The switch and the heating resistor are coupled in series between a power voltage level and a predetermined voltage level. The nozzle firing control circuit is electrically coupled to the nozzle firing circuit, and receives a selection signal and an address signal. When the address signal and the selection signal are enabled, the nozzle firing circuit is controlled to apply the power voltage level to turn on the switch to drive the heating resistor so that droplets of ink are jetted out.

Abstract: This invention disclosed a corona discharge apparatus composed of a plurality of substrate deposited with matrix of carbon nanotubes. By using ventilation device, the airflow can pass through the corona discharge apparatus, and the electric charge produced due to the corona discharge on the carbon nanotubes.

Abstract: An earplug has an open inserting end, an open inlet end, a cover, a hollow body, a soft sheath, a tube and a sound-processing unit. The sound passes through the open inlet end, is processed by the sound-processing unit and then passes into an ear canal. Alternatively, RF (Radio Frequency) signals pass through the open inlet end and are processed by the sound-processing unit, and then radio signals pass into the ear canal. The soft sheath has a through hole. The tube is mounted through the through hole in the soft sheath and allows the open inserting end to communicate with the ambient air. Furthermore, the soft sheath and the tube are replaceable to conform to sanitary standards.
