Abstract: A natural gas liquefaction process according to the present invention uses a single closed-loop refrigeration cycle employing a mixed refrigerant, thereby having a simple structure for the liquefaction process and allowing the liquefaction process to be easily operated. Furthermore, the present invention cools natural gas after one stream is separated into two streams, thereby having an excellent efficiency of the liquefaction process.

Abstract: Provided is a re-liquefying method for a stored liquid which has a simple structure or operation and excellent process efficiency. Since the method does not use separate refrigerant, the structure or operation in the re-liquefying method is significantly simplified. In addition, since a portion of a main stream is separated to form a cycle similar to a refrigerant cycle which cools the mainstream, the process efficiency of the re-liquefying method is significantly improved. The above Abstract is a more accurate literal translation of the abstract from the original priority application than the PCT abstract.

Abstract: This invention is concerned with a transmission control method and apparatus in a collision interval for a collision of multidimensional hopping patterns. In the present invention, each orthogonal wireless resource in the coordinate of the multidimensional orthogonal resource can hop according to the hopping pattern negotiated between a transmitter and a receiver, and each corresponding channel is distinguished by the hopping pattern. A specific multidimensional hopping pattern is allocated to each secondary station. The hopping pattern is either permanently allocated to the secondary stations or temporarily allocated from the primary station during a call set-up. The permanent allocation of the hopping pattern to the secondary stations is achieved when the hopping pattern is identified based on a unique identifier, such as ESN of the secondary station.

Abstract: A communication system generates a continuously orthogonal spreading code for a user, a user signal is spreading-modulated by using the continuously orthogonal spreading codes, and then the spread signal is pre-rake combined and transmitted. A receiver processes the received signal by using a matched filter for one path.

Abstract: In inspecting for quality of underfill material dispensed in an IC package, a camera image is captured for the IC package having the underfill material dispensed between an IC die and a package substrate. A data processor analyzes the camera image to determine an occurrence of an unacceptable condition of the underfill material. Pre-heating and/or post-heating of the package substrate before and/or after dispensing the underfill material by a contact-less heater ensures uniform spreading of the underfill material.

Abstract: An optimistic, latch-free index traversal (“OLFIT”) concurrency control scheme is disclosed for an index structure for managing a database system. In each node of an index tree, the OLFIT scheme maintains a latch, a version number, and a link to the next node at the same level of the index tree. Index traversal involves consistent node read operations starting from the root. To ensure the consistency of node read operations without latching, every node update operation first obtains a latch and increments the version number after update of the node contents. Every node read operation begins with reading the version number into a register and ends with verifying if the current version number is consistent with the register-stored version number. If they are the same, the read operation is consistent. Otherwise, the node read is retried until the verification succeeds. The concurrency control scheme of the present invention is applicable to many index structures such as the B+-tree and the CSB+-tree.

Abstract: A scheme for accessing a multi-dimensional index structure resident in main memory to refer to data objects stored in a database is disclosed. To reduce the amount of accessed index data, the scheme compresses a minimum bounding rectangle (“MBR”). The first step to compress the MBR is to represent the MBR relatively to a reference MBR. The relative representation of an MBR (“RMBR”) is coordinates of the MBR represented relative to coordinates of the reference MBR. In addition, quantization may be performed as an additional step for further compression. In this step, the RMBR is quantized using a finite level of quantization chosen from a given set of quantization levels. Alternatively, a proper node size can be chosen to reduce the index search time.

Abstract: A method for coupling a lid to a support substrate having a semiconductor chip coupled thereto and a clamp fixture. Each semiconductor component has a semiconductor chip mounted to a semiconductor component and a lid coupled to the support substrate via a lid attach material. The lid attach material is cured either using a two-step process that includes a partial cure step followed by a clampless cure step or by curing the die attach material in a clamp fixture without including a pre-cure step. The semiconductor component manufacture decides on the curing approach based on cost and the number of semiconductor components being manufactured. If the semiconductor manufacturer opts for curing with a clamp fixture, the clamp fixture includes a base plate insert on which the semiconductor components are placed and a compression mechanism that includes a compression plate having a compressive material disposed thereon.
