Abstract: A method for manufacturing a heat releasing semiconductor chip package includes attaching a first surface of a semiconductor chip onto an insulating film, injecting a coating liquid onto a second surface of the semiconductor chip to form a liquefied coating layer and curing the liquefied coating layer to form a heat releasing layer. The coating liquid includes a liquefied molding compound for heat releasing and fine alumina particles. Therefore, the heat releasing semiconductor chip package and method for manufacturing the semiconductor chip package form a heat releasing layer in direct contact with the semiconductor chip to maximize a heat releasing effect.

Abstract: A thrust foil air bearing has a bump foil arranged on a thrust plate. A top foil includes a flat surface extending along top bumps of the bump foil, an edge attached to the thrust plate, and a ramp connecting the edge and the flat surface. The ramp forms a curvature. The curvature has a center located in a lower part of the ramp and tangentially contacts the top of a first bump of the bump foil.

Abstract: A ring shear apparatus for measuring a shear strength of soil samples. The ring shear apparatus considering a wall-slip effect including: an upper ring for forming a first accommodation portion having a ring shape in which soil samples are accommodated; a lower ring for forming a second accommodation portion that corresponds to the first accommodation portion of the upper ring and has a ring shape in which soil samples are accommodated, closely attached to a lower portion of the upper ring and rotatably installed relative to the upper ring; a rotating unit for rotating the lower ring relative to the upper ring; and a shear strength measuring sensor combined with the upper ring and for measuring a shear strength of the soil samples, wherein a plurality of protrusions that protrudes from the lower ring is formed on an inner circumferential surface of the lower ring along a circumferential direction of the lower ring in order to prevent the soil samples from being slid when the lower ring is rotated.

Abstract: A journal foil air bearing 5000 according to the present invention is provided with one top foil 300 along an inner periphery of a hole 18 of a bearing housing 10. Bump foils 20c and 20d are installed at the inner periphery of the hole 18 of the bearing housing 10 where they are distanced from each other. Both ends of the top foil 300 form bent portions 308a and 308b and the bent portions 308a and 308b are mounted in a slot 414 of a slot body 40 mounted in a slot 140 provided in the inner periphery of the hole 18 in the bearing housing 10 and the top foil 300 is elastically movable therein.

Abstract: According to the present invention, a ramp 990 of a top foil 900 forms a curvature the center O of which is located in lower part and horizontally contacts with the first bump 81 of the bump foil 80.

Abstract: Swirler plate in a gas burner, the swirler plate having a plurality of slits formed in a radial direction for supplying a mixed gas to a combustion chamber, and a plurality of swirl vanes formed on one side of the slits for guiding the mixed gas from the slits to the combustion chamber, including a swirl vane for a flame detector having an angle of a slope formed lower than angles of slopes of other swirl vanes, the swirl vane for a flame detector having a combustion main reaction region in which the flame detector is fitted.

Abstract: A method of transferring remote controller pointing data for transferring data from a pointing device, in which power consumption is reduced, and a method for processing data received according to the transferral method, are provided. The method of transferring remote controller pointing data according to the present invention includes the steps of generating a leader pulse, indicating that the position of the pointer of a remote controller pointing device has begun to change, and generating a first pulse as a time reference point. The change of the position of the remote controller pointer is divided into vector components along X and Y axes, to obtain an X displacement and a Y displacement. The X displacement and the Y displacement data is then converted into X time data and Y time data.
