Title: Communication terminal
Inventor: CHARKANI EL HASSANI AHMED NABI
IPC: G10L21/02
Filed: 1999-09-28
Granted: 2001-06-23
Abstract: In a mobile radio terminal (2), it can happen that an burst wise transmitted RF signal causes interference in the audio  part of said terminal which results in the transmission of the interfering signal together with the audio signal to a remote subscriber. To reduce the strength of the interfering signal, interference suppressing means (24) are used. The computational complexity of the interference suppressing means (24) can be substantially reduced by using known properties of the interfering signal. If e.g. spectral properties of the interfering signal are known, it is possible to process only the frequency bands of which it is known that they comprise spectral components of the interfering signal.

Title: Fabricating method of shallow trench isolation structure
Inventor: JEN YI-MIN
IPC: H01L21/76
Filed: 1999-11-10
Granted: 2001-06-23
Abstract: This invention is about the fabricating method of shallow trench isolation structure and includes the following procedures. A substrate is provided. A mask structure is formed on top of the substrate. An oxidation process is performed onto the part of substrate which is not covered by the mask structure and is exposed to form a bird's beak oxidation structure. The mask structure and the bird's beak oxidation structure are removed to form a slowly raising convex tableland structure. After a stopper is formed on the substrate, the stopper on top of the tableland structure is removed to form an opening. Part of the substrate, which is exposed by this opening, is removed to form a trench. An isolation layer is formed on the substrate having the trench and a planarization process is performed through the use of stopper. The residual stopper is stripped off so as to form a shallow trench isolation structure.

IPC: G01J5/00
Filed: 2000-01-17
Granted: 2002-10-11
Abstract: A system and method for detecting molten slag in a tap stream between a steel making vessel such as a basic oxygen furnace (BOF) and corresponding ladle. An infrared (IR) imaging or detecting device (s) is used to image/view the BOF-to-ladle tap stream, the stream transmitting energy indicative of whether molten steel and/or slag is in the stream at a given time. Gray scale analysis is performed on pixels viewed from the tap stream to determine the number of steel pixels and the number of slag pixels in the stream at a given time. When the ratio or percentage of slag pixels exceeds a predetermined value or amount, an alarm may be actuated to cause an operator to tilt the converter upward to stop tapping, or the converter may be automatically tilted upward to stop tapping.

Granted: 2003-03-01
Abstract: The present invention provides a variable-wavelength optical recording medium and its manufacturing process, wherein a variable-wavelength material with the feature of varying the wavelength of incident light is used to make the reflective light transform to another wavelength, thereby increasing the contrast among the optical signals. The variable-wavelength optic recording medium includes a transparent substrate, a total reflection layer and at least one signal layer sandwiched between the transparent substrate and the total reflection layer. The signal layer is composed of at least one optical transformation layer (variable-wavelength material). The optical recording medium of the present invention is designed to have a multi-layered structure, i.e., multiple signal layers sandwiched between the transparent substrate and the total reflection layer. Therefore, the signal variation at a single point is not restricted in two types. Accordingly, the multi-layered structure of the present invention can greatly increase the storage capacity of the optical disk storage medium.

Title: Apparatus for cleaning and drying substrates
Inventor: FISHKIN BORIS
IPC: H01L21/304
Filed: 2000-02-18
Granted: 2001-10-01
Abstract: A method and apparatus for cleaning, rinsing and Marangoni drying substrates is provided. A line of fluid is sprayed along a substrate surface forming an air/fluid interface line, and a line of drying vapor is supplied to the interface line to achieve Marangoni drying. Thus, a large portion of the substrate is simultaneously dried. A preferred apparatus employs a tank of cleaning and/or rinsing fluid. Above the tank fluid a source of rinsing fluid directs rinsing fluid to the surface of a substrate forming a meniscus on the substrate surface as the substrate is lifted from the cleaning fluid, and a drying vapor source directs drying vapor to the meniscus. The drying vapor lowers the surface tension of the meniscus, inducing a Marangoni flow of rinsing fluid from the substrate's surface, and thereby drying the substrate. The cleaning fluid tank has a substrate receiving and cleaning portion and a substrate rinsing portion. The rinsing fluid source and the drying vapor source are enclosed by a drying enclosure above the rinsing portion of the tank. Thus, substrate loading, cleaning, rinsing, drying and unloading are performed with at least partial overlap in time.

Title: Radio communication system
Inventor: MOULSLEY TIMOTHY JAMES
IPC: H04L12/56
Filed: 2000-06-22
Granted: 2002-07-11
Abstract: The invention relates to a radio communication system having a random access packet channel for the transmission of data packets (214) from a secondary station to a primary station. Such a channel is intended for use by secondary stations having packets of data (214) to transmit to a primary station while not actually engaged in a call. A secondary station wishing to transmit data packets (214) engages in two contention resolution phases (208, 210) with the primary station. This addresses the problem with prior art systems that there is a significant chance of two secondary stations believing that they have been granted access to the channel, the resultant collisions leading to a significant reduction in system capacity.

Title: Production of aliphatic esters
Inventor: YAN TSOUNG Y
IPC: C07C67/40
Filed: 2000-10-19
Granted: 2003-04-01
Abstract: Aliphatic esters, R'COOR are produced by reacting the corresponding alcohol, ROH having carbon numbers of the alkyl groups, R' and R, between 0 and 9 and 1 and 10, respectively, with molecular oxygen in the presence of a dual functional catalyst comprising metal on acidic solid support. In particular, the process is used advantageously for production of ethyl acetate by conversion of ethanol. The reaction mixture from the reactor is separated through azeotropic distillation to recover the ethyl acetate as product and the by-product, acetaldehyde and acetic acid which could be recycled for further reaction. The process is characterized by high conversion of ethanol, high selectivity for ethyl acetate and low waste stream generation. The preferred catalyst is Pd on zeolites which is active, selective, stable and regenerable.
