Abstract: A scroll compressor and a method for producing an eccentric bush necessary for the scroll compressor, and since the scroll compressor includes: a shaft rotated by a drive source; an eccentric bush having a recess, into which the shaft is inserted, and an eccentric portion eccentric to the shaft; an orbiting scroll performing an orbiting motion in cooperation with the eccentric portion; and a fixed scroll engaged with the orbiting scroll, and the eccentric bush is formed according to a method for producing the eccentric bush for the scroll compressor including steps of sintering, sizing, and forming a coating layer such that the eccentric bush includes pore apertures and a coating layer, accordingly, the manufacturing cost and weight may be reduced, and the durability may be improved.

Abstract: An electric compressor, wherein an oil separator is formed on an inner wall on the discharge path, and wherein the oil separator is formed in a concavo-convex shape along a rotation direction of the refrigerant on the discharge path. In the compressor, the farther it is from a discharge hole along a rotation direction of the refrigerant, the greater the depth of a first groove portion formed in an oil separator is. As a result, the oil contained in the refrigerant is separated.

Abstract: The present invention relates to a method for prenatal diagnosis using digital PCR, and more particularly to a method for providing information for diagnosis of chromosomal aneuploidy in a fetus, comprising: (a) extracting DNAs from pregnant woman's blood; (b) classifying the DNAs according to size to obtain DNAs having a size of 1,000 bp or less; (c) performing digital PCR using the obtained DNAs of step (b), for a control gene located on a chromosome not associated with chromosomal aneuploidy and a target gene located on a chromosome associated with chromosomal aneuploidy; (d) calculating a ratio of a quantitative digital PCR value of the target gene to a quantitative digital PCR value of the control gene; and (e) determining that when the ratio calculated in step (d) is 0.70-1.14, a chromosome number of the fetus is normal.

Abstract: The present invention relates to a method of dental implant treatment planning, a device and a recording medium therefore. The device for dental implant treatment planning according to the present invention can move or rotate the grouped objects together in 2D or 3D model about teeth arrangement for implant treatment planning with grouping function of the implant objects. So, it decreases complexity of manipulation of the implant objects, provides users with convenience to easily modify position or size of the implant objects, and improves the accuracy of the modification.

Abstract: A lubricating coating composition and a compressor including a sliding member coated with the lubricating coating composition. The lubricating coating composition includes a thermosetting or thermoplastic polyimide-based resin as a binder, a solid lubricant, various solvents, and other additives at a controlled ratio. The compressor includes a first member including a first sliding surface and a second member moving relative to the first member including a second sliding surface. The lubricating coating composition is applied to the first sliding surface or the second sliding surface.

Abstract: The present invention relates to a method of guiding a dental implant treatment plan, a device and a recording medium therefore. The method of guiding a dental implant treatment plan according to the invention, by providing a guide to the area where the implant object is to be placed, the effects of reducing the complexity of the implant plan and decreasing procedure deviations depending on individual to individual can be achieved.
