    • PURPOSE: A rheology model selecting method for electronic printing using a micro PIV system and a micro flow chip is provided to minimize the consumption of fluid sample when a rheology model is selected by measuring non-Newtonian fluid through the fluid of 100 micron liter. CONSTITUTION: The speed distribution of non-Newtonian fluid is measured by a micro PIV(Particle Image Velocimeter) system(S1). The non-Newtonian fluid flows inside a micro flow chip. The pressure drop of the non-Newtonian fluid is measured by the micro PIV system(S2). By speed distribution and pressure drop values, relation between shear stress and shear strain are drawn(S3). By the relation, the viscosity about the non-Newtonian fluid is calculated(S4). The viscosity is marked by the graph. By the graph, the rheology model of the non-Newtonian fluid is selected(S5).

    • The present invention relates to a prism filtering system using combination of an original image and a prism image. The objective of the present invention is to provide the prism filtering system using combination of an original image and a prism image which, in combining the original image with a decreased saturation with the prism image of the same size as the original image, changes the original image and the prism image and combines the changed images, such that user interest is increased. In order to accomplish this, the system according to the present invention comprises: an image input unit which receives the original image; a prism image generating unit which generates a prism image of the same size as the original image inputted through the image input unit; a hue saturation intensity (HSI) image converting unit which converts the original image with an RGB color model to an HSI image; an RGB color model converting unit which decreases a saturation of the image, which is converted by the HSI image converting unit, and converts the image back to an image with the RGB color model; and a combining unit which combines the original image, which has a decreased saturation and is converted to the RGB color model, with the prism image, which is generated through the prism image generating unit.

    • The present invention relates to a micro gas turbine with a compact structure. More specifically, a sub journal bearing is placed between a thrust collar and a wheel of a compressor which means the bearing is placed around the thrust bearing at a compressor so that the whole length and weight of a rotator are reduced to form the compact structure. A pair of main journal bearings separated from each other at a certain distance is placed between a hollow shaft and a sleeve. The main journal bearings fully support a shaft between the compressor and turbine wherein dynamic pressure is heavily applied caused by rotation in order to maximize safety. For the purpose, the present invention comprises a turbine wheel; a tie shaft which one end part is connected to the turbine wheel; a compressor wheel which is separated from the turbine wheel to be inserted into the tie shaft; a thrust rotor separated from the compressor wheel to be fixed to the end part of the tie shaft; the thrust collar placed on a part of the outer surface of the thrust rotor; and the sub journal bearing equipped between the thrust collar and the compressor wheel.
