摘要： The present invention provides a method and apparatus for producing polymeric particles with pre-designed size, shape, morphology and composition, and more particularly the present invention uses a microfluidic polymerization reactor for producing same. The present invention disclosed herein provides a process for producing polymer particles with pre-selected shapes. The method includes injecting a first fluid comprising a polymerizable constituent with a controlled flow rate into a microfluidic channel and injecting a second fluid with a controlled flow rate into the microfluidic channel in which the second fluid mixes with the first fluid, the second fluid being immiscible with the first fluid so that the first fluid forms into droplets in the microfluidic channel. The microfluidic channel has pre-selected dimensions to give droplets of pre-selected size, morphology and shape. The microfluidic channel is sufficiently long so that the droplets have a sufficiently long residence time in the channel so that they polymerize or otherwise harden into droplets of pre-selected size and shape.

摘要： Provided are a reflection sheet for a backlight unit including: a base sheet; and a flexible coating layer, formed on at least a surface of the base sheet, containing at least one flexible elastomeric bead selected from the group consisting of an elastomeric acrylic bead, an elastomeric nylon bead, and a microcapsule resin bead having a core charged with an air or an organic material, and a backlight unit for a liquid crystal display employing the reflection sheet. The reflection sheet may further include a metal reflection layer The reflection sheet including the flexible coating layer exhibits excellent resistance to friction and impact. The reflection sheet including both the flexible coating layer and the metal reflection layer is excellent in specular reflectivity and brightness as well as in resistance to friction and impact. Therefore, the reflection sheet can be usefully applied to a light guide panel of a backlight unit having a weak surface hardness or requiring a surface protection due to a surface prism pattern.

摘要： There is provided a apparatus and method for detecting defect using multiple phase selectable pulsed eddy current (PEC), comprising: an object to be determined as to presence of a defect; a PEC irradiation unit positioned close to a surface of the object, that irradiates a PEC signal to the object and receives a defect or defect-free signal reflected from the object as a result of irradiation; a measurement unit connected to the PEC irradiation unit by a cable, being input with the reflected PEC signal received in the PEC irradiation unit, and stored with a program for time-sharing and displaying the PEC signal on a graph, that processes a resultant value to be displayed; a display unit connected to the measurement unit, that displays the resultant value being output from the measurement unit; and an input unit connected to the measurement unit, that sets a phase (a multiple phase selectable value through selecting an arbitrary location by time-sharing the measured PEC signal), frequency (a frequency value of the input PEC signal) and gain (a time axis range of the reflected PEC signal) of the PEC signal irradiated to the object.
