20150337838 | SCROLL COMPRESSOR - A scroll compressor is provided. An interference prevention portion may be formed on a side wall surface of at least one of a fixed wrap or an orbiting wrap. With such a configuration, an end of the fixed wrap may not interfere with the orbiting wrap at an arc compression surface of the orbiting wrap, but rather, be inserted into the interference prevention portion. Accordingly, occurrence of a gap between the fixed wrap and the orbiting wrap may be prevented, and thus, compression efficiency enhanced. | 11-26-2015 |
20160040667 | SCROLL COMPRESSOR - According to a scroll compressor associated with the present disclosure, the entire cross-sectional area of bypass holes formed at a compression chamber with a larger volume reduction gradient between the both compression chambers may be formed to be larger than that of bypass holes at the other compression chamber to prevent over-compression at the compression chamber with a larger volume reduction gradient, thereby enhancing the entire efficiency of the compressor. | 02-11-2016 |
20160040671 | SCROLL COMPRESSOR - A scroll compressor is disclosed which prevents leakage of refrigerant from a compression chamber and abrasion of bearings between a rotating shaft and an orbiting scroll by reducing the tilting angle of the orbiting scroll, because the allowable bearing angle is equal to or larger than the tilting angle, where the allowable bearing angle θ refers to the maximum angle at which the orbiting scroll is tilted with respect to the rotating shaft, and the tilting angle β refers to the angle at which the orbiting scroll is tilted with respect to the plate. | 02-11-2016 |
20160047378 | SCROLL COMPRESSOR - A scroll compressor is provided that may include a first scroll provided with a discharge port, a second scroll engaged with the first scroll to form a first compression chamber and a second compression chamber, and a rotational shaft provided with an eccentric portion eccentrically coupled to the first scroll or the second scroll The eccentric portion may overlap the first and second compression chambers in a radial direction. The discharge port may be provided with at least one discharge inlet and a discharge outlet The at least one discharge inlet may include a plurality of discharge inlets, which have different areas from each other, whereby a refrigerant of each compression chamber may be smoothly discharged, thereby preventing an over-compression loss due to a delay of discharge. | 02-18-2016 |
20160053759 | SCROLL COMPRESSOR - A compressor is provided. The compressor may include a fixed wrap, and an orbiting scroll having an orbiting wrap engaged with the fixed wrap to form compression chambers. The fixed wrap and the orbiting wrap may have irregular wrap curves. At least one interference avoiding portion at which a spacing between the wraps is greater than an orbiting radius or at least one gap compensating portion at which the spacing between the wraps is smaller than the orbiting radius, in a state in which a center of the fixed scroll and a center of the orbiting scroll are aligned with each other, may be provided on a sidewall surface of the fixed wrap or the orbiting wrap, whereby frictional loss or abrasion due to interference between the wraps or a refrigerant leakage due to a gap between the wraps may be prevented. | 02-25-2016 |

20140049723 | DISPLAY APPARATUS - A display apparatus includes a backlight assembly which provides a light and a display panel which receives the light provided from the backlight assembly to display an image. The backlight assembly includes a light source which generates the light, and a light guide plate. The light guide plate receives the light generated from the light source through an incident surface thereof as an incident light, and outputs the incident light through an exit surface thereof as an exit light. The light guide plate includes a first optical pattern and a second optical pattern. The first optical pattern is disposed corresponding to a first area of the exit surface and collects the incident light. The second optical pattern is disposed corresponding to a remaining second area of the exit surface excluding the first area, and collects the exit light. | 02-20-2014 |
