Abstract:
A swizzle pattern generator is provided to reduce an overhead due to execution of a swizzle instruction in vector processing. The swizzle pattern generator is configured to provide swizzle patterns with respect to data sets of at least one vector register or vector processing unit. The swizzle pattern generator may be reconfigurable to generate various swizzle patterns for different vector operations.
Abstract:
A hold-down spring unit for a top nozzle of a nuclear fuel assembly. The hold-down spring unit is coupled to the upper end of the top nozzle of the nuclear fuel assembly. The hold-down spring unit includes a first spring which provides a hold-down force upon the nuclear fuel assembly under start-up conditions or hot full power conditions of a nuclear reactor, and a second spring which provides an additional hold-down force upon the nuclear fuel assembly under start-up conditions of the nuclear reactor. The hold-down margin under start-up conditions or hot full power conditions is reduced, thus enhancing the mechanical and structural stability of the nuclear fuel assembly.
Abstract:
The present disclosure provides a method of producing high purity SiOx nanoparticles with excellent volatility and an apparatus for producing the same, which enables mass production of SiOx nanoparticles by melting silicon through induction heating and injecting gas to a surface of the molten silicon. The apparatus includes a vacuum chamber, a graphite crucible into which raw silicon is charged, the graphite crucible being mounted inside the vacuum chamber, an induction melting part which forms molten silicon by induction heating of the silicon material received in the graphite crucible, a gas injector which injects a gas into the graphite crucible to be brought into direct contact with a surface of the molten silicon, and a collector disposed above the graphite crucible and collecting SiOx vapor produced by reaction between the molten silicon and the injected gas.
Abstract:
A reconfigurable array is provided. The reconfigurable array includes a Very Long Instruction Word (VLIW) mode and a Coarse-Grained Array (CGA) mode. When the VLIW mode is converted to the CGA mode, instead of sharing a central register file between the VLIW mode and the CGA mode, live data to be used in the CGA mode is copied from the central register file to local register files.
Abstract:
There is provided a flip chip package including an electronic device, a board including a conductive pad disposed inside a mounting region of the board on which the electronic device is mounted, and a connection pad disposed outside the mounting region, a resin layer formed on the board and including a trench formed by removing a part of the resin layer, and a dam member provided on the trench and preventing the leakage of an underfill between the mounting region and the connection pad. Since the dam member, formed on the processed resin layer, can prevent the leakage of the underfill, a package defect rate can be lowered, and connection reliability can be improved.

Abstract:
The present invention relates to a top nozzle having on-off type of hold-down springs for a nuclear fuel assembly that has a two-stage elastic section such that a pushing force against the axial movement of the nuclear fuel assembly under normal conditions is optimized and at the same time a suppressing force against a drastic uplifting force of the nuclear fuel assembly under transient conditions is strengthened, and that lowers the elastic coefficients of the springs operating under normal conditions more than those of existing coil springs, thereby providing an optimal pushing force against the nuclear fuel assembly.
Abstract:
Methods of manufacturing non-volatile memory devices that can reduce or prevent loss of charges stored in a charge storage layer and/or that can improve charge storage capacity by neutral beam irradiation of an insulating layer are disclosed. The methods include forming a tunneling insulating layer on a substrate, forming a charge storage layer on the tunneling insulating layer, forming a blocking insulating layer on the charge storage layer, irradiating the blocking insulating layer and/or the tunneling insulating layer with a neutral beam, and forming a gate conductive layer on the blocking insulating layer.
Abstract:
A method for preparing a composite of zeolite-fiber substrate includes the steps of reacting a fiber substrate or a zeolite with a linking compound to form an intermediate of linking compound-fiber substrate or zeolite-linking compound, and preparing the composite of zeolite-linking compound-fiber substrate by linking the intermediate of linking compound-fiber substrate to the fiber substrate or linking the intermediate of zeolite-linking compound to the zeolite, in which the linking is induced by sonication.
