Abstract: A zoom lens system including, in an order from an object to an image: a first lens group having negative refractive power; and a second lens group having positive refractive power, wherein the zoom lens system satisfies equations below: 1.2?Fnow?2.2; 2.5<ft/fw?3; and BFL?6 mm, wherein Fnow denotes an F-number at a wide angle position, ft and fw, respectively denotes overall focal lengths at a telephoto position and the wide angle position, and BFL denotes a back focal length.

Abstract: Disclosed is a method of manufacturing a conductive coating film having superior chemical resistance or solvent resistance and durability by chemically bonding a resin having an amine group (—NH2) with carbon nanotubes having a carboxyl group (—COOH). The conductive material having high bondability with carbon nanotubes and superior electrical properties includes carbon nanotubes uniformly contained therein, and thus has appropriate surface resistivity, and thereby can be used for antistatic, electrostatic dissipation and electromagnetic shielding purposes and in transparent or opaque electrodes depending on the resistivity value.

Abstract: Disclosed is a large seamless belt which is prevented from being curled in a width direction of the belt.

Abstract: The present invention relates to a belt for an image forming apparatus, including a releasing coating layer containing at least one selected from the group consisting of a paraffin-based hydrocarbon that is also known as a paraffin wax, an isomer thereof or ester compound.

Abstract: Disclosed is a conductive layer including photopolymerizable resin having dispersed carbon nanotubes, which is transparent with high electrical conductivity and facilitates the formation of an electrode pattern. A laminate and a transparent electrode, including the conductive layer, are also provided.

Abstract: A dynamic memory management method suitable for a memory allocation request of various applications can include predicting whether an object for which memory allocation is requested is a short-lived first type object or a long-lived second type object by using index information relating to the size of the object; determining whether a heap memory includes a free block that is to be allocated to the object by using a plurality of free lists that are classified as a plurality of hierarchical levels; and allocating the free block to the object if the heap memory is determined to include the free block, wherein, if the object is predicted to be the first type object, the free block is allocated to the object in a first direction in the heap memory, and, if the object is predicted to be the second type object, the free block is allocated to the object in a second direction in the heap memory.

Abstract: Disclosed is a large seamless belt which is prevented from being curled in a width direction of the belt.

Abstract: An automatic clothes washing machine includes an outer housing, a tub mounted in the housing, and a perforated basket mounted in the tub. An ozone generator generates ozone which is conducted to water in the tub for sterilizing, bleaching and deodorizing clothes being washed. The ozone is conducted through a double-wall pipe to a perforated ozone distributor disposed between the tub and basket. The ozone generator comprises a flexible tube which is intermittently compressed by an electromagnetically controlled actuator for directing air toward an ozone-producing electrode.
