Provided are a monitoring device and method. A monitoring device includes a laser processor configured to emit a processing laser beam to perform a melting annealing process on a wafer; a laser monitor configured to emit a monitoring laser beam onto the wafer while the laser processor performs the melting annealing process, the laser monitor configured to measure reflectivity of the wafer; and a data processor configured to process data on the reflectivity measured by the laser monitor, and monitor one or more characteristics of the wafer based on the data on the reflectivity.

An apparatus for treating a substrate includes a chamber including a space in which a substrate is treated, a support member disposed in the chamber and supporting the substrate, and a heating member for heating the substrate. The space is divided into an upper space and a lower space by the support member. The support member includes a support plate receiving the substrate, a base supporting the support plate, exposing a bottom surface of the support plate and including a cut region formed in an edge portion of the base, and an adjustment block held in the cut region and coupled to the base. The cut region fluidly connects the upper space to the lower space. The adjustment block divides the cut region into a plurality of vents.

Apparatus for treating a substrate

A transparent plate and a substrate processing system including the same are disclosed. The substrate processing system may include a chamber, a lamp provided below the chamber, and a plate provided in the chamber to load a substrate. The plate may include a center region having a first transmittance value and an edge region having with a second transmittance value higher than the first transmittance value.

Transparent plate and substrate processing system therewith

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.

Roll-to-roll printing system

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.

Cleaning apparatuses for printing plates and printing apparatuses including the same

The disclosed method for reducing HRC mode reception time of CATV signals is intended for television receivers or video tape recorders provided with a CATV receiver suitable for the North American CATV system but not provided with a CATV mode (STD, HRC and IRC) selection switch. If a channel is selected, corresponding modulation frequency data is transmitted to a tuner. Subsequently, the video signal is checked for the presence of synchronizing signals, and this information is used to determine whether the broadcast is in STD mode or in HRC mode, prior to broadcast signal reception. This eliminates waiting time, reducing HRC mode reception time to only about 100 ms (the time needed to check for the presence of the synchronizing signals), and prevents noises from being generated as well as improving reception quality.
