Abstract: A photoresist supplying system includes a pump that includes a first tube phragm that stores a photoresist and a filter that filters the photoresist, a second tube phragm that stores the photoresist and is disposed outside the pump, where the second tube phragm transfers the photoresist to the first tube phragm, a storage unit that stores the photoresist, where the storage unit provides the photoresist to the second tube phragm, and a tube phragm drive unit that is connected to the first tube phragm. The tube phragm drive unit adjusts an interior volume of the first tube phragm and applies a pressure to a flexible outer wall of the first tube phragm to transfer the photoresist from the first tube phragm to a nozzle installed in the chamber. At least a part of the photoresist stored in the first tube phragm is transferred to the second tube phragm.

Abstract: A phased array RF coil module and an imaging apparatus using the same can receive a magnetic resonance signal generated from a target object at high receive sensitivity and improve a signal to noise ratio. The phased array RF coil module includes at least one first phased array RF coil unit generating a magnetic field having a component horizontal with the surface of a target object and a second phased array RF coil unit formed horizontally with the surface of the target object and generating a magnetic field having a component vertical to the surface of the target object. The imaging apparatus using the phased array RF coil module is a magnetic resonance imaging apparatus.
