  • Patent number: 10408527
    Abstract: A refrigerator includes a first combining member arranged on a side of a cooling room such that the side of the cooling room and a side of a evaporator are hooked with each other in a first direction and a second combining member arranged on the side of the cooling room, the other side of the evaporator is inserted into the second combining member in a second direction, which is different from the first direction, to combine the other side of the evaporator and the one side of the cooling room. Assembly performance is improved with a combining member that facilitates an evaporator to be combined onto an inner side of a cooling room, and heat exchanging performance is improved by the combining member enabling the evaporator to be combined onto a side of the cooling member with a gap.

  • Publication number: 20150275545
    Abstract: Provided are a door handle and a refrigerator having the same. The number of post-processes of a gripping portion is reduced, and a cross-section of the gripping portion is simplified so that the weight of the gripping portion is reduced and manufacturing cost of a door is reduced. The door handle includes a gripping portion in which a hollow cavity is formed. The door handle also includes supporting portions disposed at a front side of a door. The door handle further includes a connection cap that is mounted on the supporting portion and has an outside surface formed to correspond to an inside surface of the gripping portion. The connection cap is inserted into the hollow cavity formed in the gripping portion.

  • Patent number: 7325174
    Abstract: The present invention relates to a pre-processing apparatus using nonuniform quantization of a channel reliability value and a low density parity check (LDPC) decoding system. The pre-processing apparatus can present degradation in performance and be embodied simply by performing decoding pre-process by estimating a discrete channel reliability value (Lc*) through nonuniform quantization of a channel reliability value based on a relations between a bit error rate (BER) estimated through a simulation performed in advance and a standard deviation (?) of channel noise within a predetermined range of noise estimation error and p, and bit-shifting a receiving signal as much as a discrete channel reliability value. The pre-processing apparatus includes: a channel reliability measuring unit, a nonuniform quantizing unit, a sign bit adding unit, a bit shifting unit.

  • Patent number: 6712602
    Abstract: Disclosed is a hybrid high pressure catalytic combustion burner employing catalysts and CST combustion with staged mixing systems, in which a primary combustion gas containing reacted gas of a primary gas mixture, which is formed via catalytic combustion, is subject to a secondary mixing with the primary gas mixture containing fuel and high temperature air, completing stable high temperature CST combustion at ultra lean conditions, thereby achieving high temperature combustion reducing formation of NOx.
