Title: Virtual client to gateway connection over multiple physical connections
Inventor: HALL GEORGE E JR
IPC: H04L69/40
Filed: 1999-08-30
Granted: 2001-09-11
Abstract: A method, system, and computer program by which a logical network connection can be maintained in the presence of disruption or failure of the underlying physical network connection. The technique defines a virtual connection between the client and gateway, which is not dependent upon continuous connectivity in the underlying physical connection, and can resume operation transparently even though the physical connection may be established on a different media type. Additionally, the technique of the present invention enables the physical medium to be changed even though the physical connection was not disrupted. This change in medium may be based on a number of factors, such as quality of service or transmission speed, which can be monitored. A graphical user interface (""GUI"") is defined whereby the human user may observe a depiction of the available physical connections and their status, information regarding the physical connection currently in use, ect. The user may initiate changes to the current physical connection from this GUI, without disrupting the logical connection.

Title: Optical information recording medium, optical information recording apparatus, and method of recording test signal on the same
Inventor: NARUMI KENJI
IPC: G11B7/125
Filed: 1999-09-03
Granted: 2001-12-01
Abstract: The present invention provides an optical information recording apparatus, an optical information recording method, and an optical information recording medium that enable information signals to be recorded precisely by determining the recording conditions such as recording power, edge positions of recording pulses, and the like suitably before recording the information signals. An edge test signal generation circuit (4) supplies a test signal for optimizing the edge positions of the recording pulses. In order to suppress the variation in the intervals between edges due to the mark distortion caused by overwriting, test recording is carried out in a plurality of sectors on the optical information recording medium (1) with a test recording start point being shifted at random in each sector by a recording start point shifting circuit (3). A system control circuit (2) calculates an average of intervals between the edges in test signals reproduced from the plurality of sectors, and determines the difference between the average and an original interval between edges in the test signal, thus determining a compensation volume for edge positions.

Title: Semiconductor device and method of manufacture thereof
Inventor: NAKAZATO KAZUO
IPC: H01L27/108
Filed: 2000-02-15
Granted: 2001-12-01
Abstract: A large DRAM (dynamic random-access memory) uses rather low cell read voltage, and its operation is likely to be unstable. If the memory cell is designed for a gain to amplifying signal voltage, then the memory cell area increases. Therefore, there is a need for a RAM with small-area memory cells capable of stabilized operation. A semiconductor device according to this invention comprises a three-dimensional cell structure that includes MOS transistors (2, 3, 4, 5) for reading information, transistors (8, 11b) for writing information, and a capacitor (11a) for controlling the voltage at storage nodes.

Title: High efficiency line driver for high crest-factor signals such as DMT/ADSL signals
Inventor: MCCUNE EARL W
IPC: H04L27/26
Filed: 2000-02-22
Granted: 2002-03-21
Abstract: The present invention, generally speaking, achieves a highly efficient line driver for high crest-factor signals such as DMT/ADSL signals. In an exemplary embodiment, a digital signal produced by a digital signal processor or the like is processed by a sigma-delta modulator to produce one or more binary signal pairs. The signals of a signal pair are low-pass filtered, if necessary, and applied across the winding of a transformer. The transformer has a single secondary winding connected to the line and may has as many primary windings as the number of signal pairs. The transformer may have a unity turns ratio or may have a turns ratio for accomplishing voltage step-up. For one signal pair, the number of possible resulting signals levels on the secondary side is three, for two signal pairs five, etc. Using more than two signal levels, it becomes possible to recreate from the digital signals the corresponding analog waveform with the required accuracy. The circuit requires only a single supply voltage, is inherently balanced and provides high-voltage DC isolation.

Abstract: In a sound synthesizer, a noise adder generates a noise signal having a frequency band of 3,400 to 4,600 Hz, adjusts the gain of the noise signal, and adds the gain-adjusted noise signal to an excitation source excW after being filled with zeros by a zero-filling circuit, thereby providing a wide-band excitation source excW' which is rather flat. The signal gain is adjusted by determining a narrow-band excitation source or a power of the wide-band excitation source after being filled with zeros and fitting the gain to the narrow-band excitation source or the power.

Abstract: A mask material which is the same as that of a wafer to be exposed is prepared (step Q1), and the proximity effect correction dose for mask-writing is operated. Then, a resist film of the mask material is exposed by a pattern accompanying a correction dose twice the proximity effect correction dose in mask-writing at the same accelerating voltage as in wafer-exposing (step Q2).

Thereafter, by using this mask, the resist film on the wafer is EB-exposed without proximity effect correction (step Q4). According to the present invention, the time required for calculation processing is shortened and the calculation accuracy is improved.

Title: Magnetron with cooling system for substrate processing system
Inventor: CROCKER STEVEN CHARLES
IPC: H05H1/46
Filed: 2000-10-11
Granted: 2002-09-11
Abstract: The present invention generally provides a vacuum processing system with a process chamber and a rotating member, such as a magnetron in a PVD chamber, disposed in a cooling cavity of the process chamber, where the rotating member includes a deflection member for deflecting cooling fluid in the cooling cavity toward interior portions of the rotating member. In one embodiment, a base plate of the rotating member defines an upper surface of the rotating member and a magnet retainer defines a lower surface of the rotating member. Magnets are mounted between the base plate and the magnet retainer. The deflection member is mounted between the magnets and can be coupled to the magnets on one or both ends. One end of the deflection member is disposed toward the outer perimeter of the magnetron and the other end of the deflection member is disposed toward the interior portions of the rotating member. As the rotating member rotates, the deflection member deflects the cooling fluid from the side of the rotating member and forces the fluid into the interior portions of the rotating member. Heated fluid and/or air pockets in the interior portions are at least partially displaced by cooler fluid forced into the interior portions of the rotating member. A flow of cooling fluid provides cool fluid coming into the cooling cavity while heated fluid exits the cooling cavity.

Title: Enchanced light extraction through the use of micro-led arrays
Inventor: DENBAARS STEVEN P
IPC: H01L33/22
Filed: 2000-12-02
Granted: 2001-11-21
Abstract: The invention describes new LED structures that provide increased light extraction efficiency. The new LED structures include arrays of electrically interconnected micro-LEDs (12) that have and active layer (14) sandwiched between two oppositely doped layers (16, 18). The micro-LEDs are formed on a first spreader layer (18) with the bottom layer (16) of the micro-LEDs in contact with the first spreader (18). A second spreader layer (24) is formed over the micro-LEDs (12) and in contact with their top layer (16). The first spreader layer (18) is electrically isolated from the second spreader layer (24). Each of the spreader layers (20, 24) has a contact (22, 26) and when a bias is applied across the contacts (22, 26), current spreads to the micro-LEDs (12) and they emit light. The efficiency of the new LED is increased by the increased emission surface of the micro-LEDs (12). Light from each of the micro-LEDs active layer (14) will reach a surface after travelling only a short distance, reducing total internal reflection of the light. Light extraction elements (LEEs) (82, 84, 86, 88, 90, 92, 94) between the micro-LEDs (12) can be included to further enhance light extraction. The new LEDs are fabricated with standard processing techniques making them highly manufacturable at costs similar to standard LEDs.
