Title: Quantum well structures and methods of making the same
Inventor: KARLICEK ROBERT F JR
IPC: H01L33/00
Filed: 1999-11-16
Granted: 2001-10-21
Abstract: In deposition of a quantum well structure for a light emitting diode, each well layer is formed by a two-phase process. In a first phase, relatively high flux rates of gallium and indium are employed. In the second phase, lower flux rates of gallium and indium are used. The well layer is formed with a composition which varies across the horizontal extent of the layer, and which typically includes clusters of indium-enriched material surrounded by regions of indium-poor material. The resulting structure exhibits enhanced brightness and a narrow, well-defined emission spectrum.

Abstract: This invention provides a pyrolysis catalyst supplying device, particularly to one where along a recycle piping of degraded products in a degrading tank is provided with a full pressure gauge, a static pressure gauge, a thermocouple, a hydrocarbon concentration gauge, and a nitrogen asides, oxygen and carbon dioxides concentration gauge, where the readings of full pressure, static pressure, temperature, concentration of degraded products and concentration of other nitrogen asides, oxygen and carbon dioxides as detected in the recycle piping are transmitted into a controller for continuous computation of required amount of catalyst, based on which the rotating speed of the pump is controlled so as to supply an appropriate amount of catalyst into the degrading chamber. Such a process is repeated until the amount of the degrading products is reduced to the end of the degrading process. At this time, the catalyst supply is stopped to prevent unnecessary waste of the catalyst and evaporation of the catalyst during the degrading process, while improving the degrading effects.

Title: Synthesis of hydrothermal stable, containing metal mesoporous MCM-41 molecular sieve
Inventor: JENG SHU-FEN
IPC: B01J29/70
Filed: 2000-01-20
Granted: 2001-12-21
Abstract: Along with the development of the mesopore molecular sieve, hydrothermal stable molecular sieve containing metal mesoporous MCM41 molecule synthesizes. The applications of a molecular sieve catalyst have evolved from a micromolecule catalytic reaction to macromolecule catalytic reaction. Particularly, in the cracking of heavy oil and reactions of medicine and special chemicals, the pore size of the required molecular sieves often requires expansion to mesopore range. A MCM-41 molecular sieve has a high surface area (BET surface area of about 1000 m<SP>2</SP>/g), a high thermal stability, a consistent pore size and an adjustable size of pore channel. So far, its largest weakness in its application as a catalyst lies on its hydrothermal stability. The objective of the present invention is to synthesize a water heat stable MCM-41 molecular sieve. The results indicate that when the synthesized gel is mixed with a suitable amount of short-chain ammonium salt ions or sodium ions, the water heat stability of the synthesized molecular sieve with medium void channel can be conspicuously increased. The method can also be used to synthesize MCM-41 molecular sieves containing aluminum and transition metal ions. After calcining or water heat treatment, most aluminum and transition metal ions still remain on the skeleton structure.

Granted: 2001-09-21
Abstract: In a semiconductor device such as a CSP, re-wiring is provided on a circuit element formation region of a semiconductor substrate and a columnar electrode for connection with a circuit board is provided on the re-wiring. A first insulating film is provided over the semiconductor substrate excluding a connection pad, and a ground potential layer connected to a ground potential is provided on an upper surface of the first insulating film on the circuit element formation region. A re-wiring is provided over the ground potential layer with a second insulating film interposed. Since the ground potential layer serves as a barrier layer for preventing crosstalk between the re-wiring and circuit element formation region, it is possible to eliminate crosstalk between the re-wiring and a circuit within the circuit element formation region and to freely position the re-wiring without restrictions. Furthermore, a thin-film circuit element may be provided at a given location on the second insulating film. In a structure wherein the thin-film circuit element is provided on the second insulating film, a second ground potential layer is provided as a second barrier layer over the thin-film circuit element with an insulating film interposed, and re-wiring is provided over the second ground potential layer with an insulating film interposed. Thereby, crosstalk between the re-wiring and thin-film circuit element can be eliminated, and the re-wiring can be freely positioned without restriction.

Title: Electrostatic discharge protection circuit structure of high voltage device
Inventor: PAN RUEI-SHIANG

Granted: 2002-01-01
Abstract: The present invention relates to the electrostatic discharge protection circuit structure of high voltage device, in which P-type ions, such as boron ions, are implanted into the high voltage P-well region of the original NMOS part. Thus, the impedance value of high voltage P-well region in the electrostatic discharge protection circuit structure of the original high voltage device is decreased and fast return voltage value is increased so as to assure that latch is not occurred. In addition, the separation between fast-return voltage and triggering voltage is decreased. Therefore, it is capable of reducing the risk of non-uniform conduction for the electrostatic discharge protection circuit of finger-shaped high voltage device.

Title: Slave clock generation system and method for synchronous telecommunications networks
Inventor: TONKS DAVID JOHN
IPC: G06F1/08
Filed: 2000-05-27
Granted: 2001-09-11
Abstract: A slave clock generation system and method suitable for use with synchronous telecommunications networks generates one or more slave clocks (16) from a selected reference clock (Ts) using a direct digital synthesis technique. A multiplexer (20) selects a reference clock from a number of available sources (12), each of which can be at its own spot frequency, based on a predetermined selection order. Toggle detectors (42) monitor each of the available clock sources, and block the selection of any that are not within a specified frequency range. A local oscillator (24) establishes short-term and long-term measurement periods; the cycles of the selected reference clock are counted over consecutive short-term measurement periods to determine the relative frequency of the selected clock with respect to the frequency of the local oscillator. The cycle counts are fed to a phase-to-clock converter (80), which produces a slave clock output having a frequency that varies with the relative frequency measured for the selected clock. Rounding errors are countered by monitoring both the generated slave clock and the selected reference clock over a long-term measurement period, with the difference (B-C) between these two cycle counts used in a feedback path to correct the output frequency. The invention's mostly-digital implementation improves its noise-rejection and suppression characteristics, and enable the system to be integrated on a common substrate.

Title: Addressing of a memory
Inventor: PERTHUIS HUGUES DE
IPC: G06F13/16
Filed: 2000-09-20
Granted: 2003-03-11
Abstract: A processing of data in cooperation with a memory (MEM), for example an MPEG decoding, has the following characteristic features. A processor (P) generates a logic request (LRQ). The logic request (LRQ) defines at least one characteristic (CAR) common to a group of data (GRP). An addressing circuit (AGA) generates a physical request (PRQ) on the basis of the logic request (LRQ). The physical request (PRQ) defines memory (MEM) addresses (A) relating to the group of data (GRP). A memory interface (INT) effects a transfer (TRNSFR) of the group of data (GRP) between the memory (MEM) and the processor (P) on the basis of the physical request (PRQ). Thus, the processor need not know how and where the data to be processed or having been processed are stored in the memory. This facilitates the design of a data processing device and, particularly, a family of such devices.
