摘要:
A light guide plate having a pattern to minimize generation of a dark zone and a backlight unit including the same are disclosed. The light guide plate includes an intaglio pattern consisting of recesses formed in a surface opposite to a light emitting surface thereof to have a cross section having major-axis and minor-axis diameters and depth, the recesses being spaced apart from one another in first and second directions by first and second distances respectively. The density of the intaglio pattern is directly proportional to the major-axis and minor-axis diameters and depth, and is inversely proportional to the first and second distances. The intaglio pattern has the minimum density in a first region adjacent to a light source, and the maximum density in a second region that is the maximum distance from the light source. A density ratio of the maximum density to the minimum density is 900.

Provided is an ignition plug used for an internal-combustion engine. The ignition plug includes: a center electrode; an insulator disposed outside the center electrode; a metal housing disposed outside the insulator; a ground electrode having an end connected to the metal housing and the other end facing the center electrode; and an electrode tip fixed to one or more of the center electrode and the ground electrode. The electrode tip is made of an alloy of iridium Ir, hafnium Hf, and niobium Nb. Therefore, the ignition plug with the low-cost iridium can have high resistance to prevent an iridium element from oxidizing and vaporizing in high speed driving conditions.

A refrigerator that is capable of easily operating a storage chamber (30) where cooling is carried out independently from a cold chamber (10) is disclosed. The refrigerator includes a refrigerator body having a cold chamber (10) defined therein and a storage chamber (30) disposed in the cold chamber, a cool air generation chamber having a cooler and a fan (102) for supplying cool air mounted therein, a partition plate for partitioning the cold chamber (10) and the cool air generation chamber from each other, the partition plate having a main flow channel (103) for guiding the cool air supplied by the fan (102) to the cold chamber (10) and at least one cool air hole (201) located between the fan (102) and the main flow channel (103) for bypassing the cool air, and at least one bypass duct (200) for guiding the cool air bypassed through the at least one cool air hole (201) to the storage chamber (30).
摘要:
An apparatus for storing food is provided that includes a food storage chamber, a cooling device, a scroll-type fan housing with a fan, and a duct that guides cool air from the scroll-type fan housing to the food storage chamber. The scroll-type fan housing may be located to the left or right of the cooling device, and the duct may be located above or below the cooling device and the scroll-type fan housing. Alternatively, the scroll-type fan housing may be located above or below the cooling device, and the duct located on a left or right side of the cooling device and the scroll-type fan housing. These arrangements result in more usable space within the food storage chamber than other conventional arrangements.

An apparatus for storing food therein and method for manufacturing the same are disclosed. Space utilization efficiency can be enhanced by configuring a single-body duct diverging to different storage rooms. The present invention includes a first storage room and a second storage room to store food, and a duct unit includes a first duct to guide cold air into the first storage room, and a second duct to guide cold air into the second storage room. A scroll from which the first duct and the second duct diverge is located between the first and second ducts.
摘要:
A refrigerator having a controller and a method substantially allowing an independent cooling operation of a first compartment, e.g., cooling compartment and a second compartment, e.g., storing compartment. The storing compartment may be maintained at a cooling or preservation temperature which may be lower than a cooling or preservation temperature of the cooling compartment.
