Abstract: A system for photolithography may include an exposure chamber providing a first isolated environment, an exposure stage in the exposure chamber, a radiation source, an interface chamber providing a second isolated environment, a port, a post exposure bake heater in the interface chamber, and a wafer handler. The exposure stage may be configured to receive a wafer having photoresist thereon to be exposed, and the radiation source may be configured to provide exposing radiation to the wafer being exposed. The port may be configured to allow wafer transport between the first and second isolated environments of the exposure and interface chambers, and the post exposure bake heater may be configured to bake the wafer after exposure.

Abstract: An apparatus for fabricating a flat panel display device includes a substrate on which a picture display section is formed and a stage on which the substrate is loaded. A dispenser applies a sealant along an outer line of the picture display section in the substrate. A light detector emits light toward the sealant and detects the amount of reflected light in real-time. A controller detects broken lines in the sealant in accordance with a signal supplied from the light detector and controls the dispenser so as to re-apply the sealant to spaces in the broken line in which the sealant is not present.

Abstract: The present invention relates to a method of providing a routing protocol in a sensor network. The routing protocol is a new model which is made considering a battery efficiency so that an AODV protocol, which is widely used because of its simplified and reliable algorithm, can be matched to a sensor condition. An energy information of a node is contained in the RREQ message of the AODV, thereby allowing the neighboring nodes and the nodes on the path to know their energy states.

Abstract: A telephone apparatus which allows a wired or wireless telephone subscriber to change a call forwarding telephone number at a remote location, and a call transfer method therefor. The call transfer method includes: receiving a call from an external telephone; determining whether a caller of the external telephone is a valid user; receiving a call forwarding telephone number from the caller; and outputting a call transfer request signal and the received call forwarding telephone number to a switching system.

Abstract: A method for handoff between packet data serving nodes (PDSNs) The method for handoff between packet data serving nodes (PDSNs) provides packet services to a mobile node. A new PDSN receives subscriber information of a mobile node from at least one or more old PDSNs forming a communications network. The new PDSN recognizes the mobile node moving into a concerned area of the new PDSN and then transmits recognition information on the mobile node to an old PDSN to which the mobile node was connected. All received information on the mobile node is transmitted by the old PDSN based on the recognition information. A communication channel is established with the mobile node based on the received information. In the method, handoff is performed without reestablishing PPP. Accordingly, handoff between PDSNs can be performed faster, reducing the time needed for establishing a PPP session with a terminal and for terminating a previously set up PPP session.

Abstract: The present invention relates to optically active herbicidal (R)-phenoxypropionic acid N-methyl-N-2-fluorophenyl amide compounds represented in the following formula (1), a method for preparing thereof, their use to prevent generation of barnyard grass produced from rice and composition as suitable herbicides, (I) wherein X is hydrogen, halogen, hydroxy, NH2, CO2H, C1-C6 alkylamino substituted with 1 or 2 of C1-C3 alkyl, C1-C6 alkyl, C1-C6 alkoxy, C1-C3 haloalkyl, C1-C3 haloalkoxy, C2-C4 alkoxyalkoxy, C1-C4 alkylthonyl, C1-C4 alkylsulfonyl, C2-C6 alkenyl, C2-C6 alkinyl, C2-C6 alkenyloxy, C2-C6 alkinyloxy, C1-C3 alkoxycarbonyl, or C1-C3 alkylcarbonyl; is hydrogen or fluoro; and n is an integer of 0 to 2, wherein X can be a combination of other substituents when n is 2.

Abstract: A protective cover for a cleat shoe comprises a sole an upper surface of which is surrounded by an edge line, and a vamp to guide and support with the sole the cleat shoe in the cover. The edge line includes a rear end arc line belonging to a sole heel portion. The vamp includes a lower end line having points each attached to and along the edge line excepting the rear end arc line of the sole heel portion. The lower end line is upwardly waved between the points to form openings through between inside and outside of the cover. First and second vamp straps are opposedly formed to extend rearward from each guide vamp portion adjacent to the rear end arc line of the sole heel portion to allow the first vamp strap to become detachably attached to the second vamp strap when required.
