摘要:
A roll-to-roll printing system includes driven rolls to apply a feeding force to a flexible substrate so that the flexible substrate is fed from an unwinder to a rewinder, nip rolls respectively disposed above two opposite end portions of each of the driven rolls to pressurize two opposite side portions of the flexible substrate, nip roll driving motors connected to the nip rolls to rotate the nip rolls, and a control unit to receive information regarding change of torque values of the nip roll driving motors and control tension of the flexible substrate based on the information.

A printing plate cleaning apparatus may include a cleaning chamber configured to receive a printing plate to be cleaned, a nozzle supporter in the cleaning chamber, and/or a unified nozzle unit that includes a cleaning nozzle unit and a rinsing nozzle unit unified as a body and attached to the nozzle supporter. The cleaning nozzle unit may include a cleaner nozzle configured to inject cleaner to the printing plate and/or a first suction nozzle suctioning waste. The rinsing nozzle unit may include a rinsing liquid nozzle configured to inject rinsing liquid to the printing plate and/or a second suction nozzle suctioning the waste. A printing plate cleaning apparatus may include the cleaning chamber, a cleaning nozzle unit in the cleaning chamber, and/or a rinsing nozzle unit in the cleaning chamber. The cleaning and rinsing nozzle units may be configured to move together with each other in the cleaning chamber.
摘要:
A reverse link controlling method in a mobile communication system. To increase or decrease a reverse data rate, an MS receives threshold power information indicating a power threshold for a pilot channel from the BS and measures the reception power of the pilot channel received from the BS. When the MS is supposed to increase or decrease the current data rate, it increases the current data rate by two levels or decreases the current data rate by one level if the pilot reception power is higher than the power threshold, and increases the current data rate by one level or decreases the current data rate by two levels if the pilot reception power is equal to lower than the power threshold.
