of the nozzle deposits a slightly different pattern. Thus line by line the complete text or the drawing is formed. After the whole page has been printed, a new sheet of paper is inserted and a new text or a new drawing is created.
In 3D printing, after the first layer has been completed, either the vertical position of the nozzle is raised at least 0.1mm (0.004 inch), which is equal to the thick

Considering material price and realistic situation, we made 3.6cm3 acrylic cubic cases.
First, Cut acrylic cubic case for 0.2cm x 3.6cm x 3.6cm size. Cover copper tape on it and elongate copper tape`s tail to connect electrode. Then, cover 3cm x 3cm cut wire mesh on it.Because of the thickness of th
for identical plane of sample and glass plate.
When we fill up a sample at a holder, if a surface of sample is identical with a surface of holder, A rotation-axis of goniometer is identical with a surface of sample(Fig. 12(a)). If a surface of sample is higher or lower than a surface of holder, a diffraction line is shift to one side(Fig. 12(b)), thus we undergo a difficult analysis.
of some 100W @ 100wph tput.
Seconds, to enable pattern transfer of features down to 11nm, the resist blur(diffusion length) has to be reduces to at least 5nm.
Third, It is important to get good adhesion between photo-resist and silicon wafer. The smaller the pattern size is, the slimmer the thickness of resist coating on silicon wafer is. As a results, because of bad contact, photo-resist can
of 막걸리 and each brands has differentiated products by their thickness. In this project, we are going to cover the KSD 막걸리 product lines.
The motivation behind our project is based on the current threat that KSD products are facing. KSD once had successfully expanded their customer group even to young generation. However, competitors started marketing activities while KSD’s stra

1) Course of pipeline from knock-out drum on the first floor to storage tank on the third floor.
It is ideal to design pipelines using straight line for economic feasibility and efficiency but that is impossible for the reason of structure of plant. So It is necessary to inspect the structure of plant.
2) What kinds of pipe do we decide?
Considering economi

The measured MOS capacitance (called gate capacitance) varies with the applied gate voltage.
① Measurement of C-V characteristics
-Apply any DC bias, and superimpose a small (15 mV) ac signal
-Generally measured at 1 MHz (high frequency) or at variable frequencies between 1KHz to 1 MHz
-The dc bias VG is slowly varied to get quasi-continuous C-V characteristics
② C-V chara
A filter is widely used in overall RF system. There are many species and structures in filter. A filter seems to be simple, but there are many considerations to design filter. In this paper, we design microstrip bandpass filter which has bandwidth of 500 MHz and center frequency of 2.5 GHz. Alumina is used as substrate, and chromium is used as conductor. Final results are achieved as follows. Ins
