Title: Method of producing shallow isolation trench
Inventor: YOU TSUEI-RUNG
IPC: H01L21/762
Filed: 1998-09-02
Granted: 2000-10-21
Abstract: A method of producing shallow isolation trench comprises the steps of forming an insulating layer on the shallow isolation trench substrate which has active regions of different sizes; coating a photoresist layer on the insulating layer when it is formed; etching to remove part of the photoresist layer until part of the oxide layer exposes such that the remained photoresist material forms a photoresist cover on the recession of the insulating layer; using the photoresist cover as a mask to etch the insulating layer to remove part of the exposed oxide layer and form a trench in the oxide layer; and then, removing photoresist cover and proceed with the chemical mechanical polishing to polish the insulating layer until silicon nitride layer exposes, to complete the manufacturing process of shallow isolation trench.

Title: Battery charge indicator
Inventor: PARSONAGE PETER CECIL JOSEPH
IPC: G01R31/36
Filed: 1999-02-26
Granted: 2000-12-21
Abstract: An automotive battery charge indicator uses an algorithm expressed by fixed component values to determine if the remaining charge in the battery has fallen below a predetermined threshold. A current sensing resistor 8 (having a resistance of the same order of magnitude as the internal resistance of the battery 1 to be monitored), is connected in series with the positive battery terminal 2 of a lead acid battery 1 and the positive side of a non-critical load 4. A percentage of the voltage across the load detected as input 6 is compared by comparator 11 with a dynamic reference voltage at input 5. The dynamic reference voltage is made up of a fixed reference voltage 7 less the voltage drop through current sensing resistor 8. When the percentage of load voltage at 6 is less than the dynamic voltage at 5, the comparator provides a negative output at 12 indicating that the remaining charge in the battery has fallen below the preset threshold value. The output from the comparator can be used to operate an indicator such as an LED or it could be used to initiate circuit shutdown to protect the battery from being discharged excessively.

Granted: 2001-11-21
Abstract: An integrated circuit (203) for use in processing streams of data generally and streams of packets in particular. The integrated circuit includes a number of packet processors (307, 313, 303), a table look up engine (301), a queue management engine (305) and a buffer management engine (315). The packet processors include a receive processor (421), a transmit processor (427) and a risc core processor (401), all of which are programmable. The receive processor and the core processor cooperate to receive and route packets being received and the core processor and the transmit processor cooperate to transmit packets. Routing is done by using information from the table look up engine to determine a queue 215 in the queue management engine which is to receive a descriptor 217 describing the received packet's payload. The transmit processor reads descriptors from a queue and transmits the payload described in the descriptor. The core processor, the transmit processor, and the receive processor operate in parallel. Local memory and registers in the packet processors, the queue management engine, and the buffer management engine are part of a global address space (321). The packet processors include serial processor (307) for processing packets received in serial media and at least one parallel processor (303). The parallel processor may be used to connect the integrated circuit with another integrated circuit of the same type, with a bus, or with a switching fabric. The packet processors may be further configured by setting bits in registers in global memory. Configurations include aggregation of serial packet processors, recirculation of a data stream within a serial packet processor, bypassing components of the receive or transmit processors, and configuring a serial packet processor's I/O pins to deal with different transmission media.

Granted: 2001-08-11
Abstract: The present invention provides a method for combining a heat pipe with a heat sink, which comprises: coating a layer of solder on the joint face between a heat pipe and a heat sink; after combining the heat pipe with the heat sink, heating the combination in a vacuum heating furnace in a vacuum of 10<SP>-1</SP> to 10<SP>-4</SP> torr allowing the solder, which is molten during the heating process, to permeate into the joint face of the heat pipe and the heat sink by the capillary effect generated during the heating process, thereby achieving a tight combination. The abovementioned method enables a tight combination between the heat pipe and the heat sink, while reducing the oxidation layer of the heat sink, increasing the K value, and having an excellent heat dissipating effect.

Title: Method of false twist texturing a synthetic yarn to a crimped yarn
Inventor: NOELLE WOLFGANG
IPC: D02G1/02
Filed: 2000-07-14
Granted: 2002-03-21
Abstract: The invention relates to a method for false twist texturing a synthetic yarn, as well as the thus-produced crimped yarn. By this method, a false twist is produced on the yarn at a speed of a false twist unit, which exceeds 2.2 times of the yarn speed and is above a saturation limit for absorbing a false twist in the yarn. The overtwisted yarn is set in the false twist zone at a temperature higher than 200 DEG C. In proportion with the advancing speed, the withdrawal speed does not exceed 1.4 times the advancing speed, and is below 1,000 m/min. With that, a false twist textured crimped yarn is produced, which has large and small cross sections with curls and bows, which alternate with one another and have opposite directions of twist.

Title: Apparatus and method for introducing water treatment chemicals to a water stream
Inventor: ZIEMER ROBERT R
IPC: B01F5/04
Filed: 2000-07-26
Granted: 2003-08-01
Abstract: First and second quill members introduce water treatment chemicals to a water stream advancing within water containing equipment having only a single opening. The first quill member extends through a sealed opening on a wall of the equipment and has a first inlet located outside of the equipment, a first outlet located within the equipment in the path of the advancing water stream, and a first passage extending between the first and second inlets. The second quill member is mounted on the first quill member and has a second inlet located outside of the equipment and a second outlet located within the equipment in the path of the advancing water stream. The second outlet is spaced from the first outlet and a second passage, coaxial with the first, extends between the second inlet and the second outlet. A first chemical substance flowing through the first passage and issuing from the first outlet into the water stream thereby avoids mixing in a concentrated form with a second chemical substance flowing through the second passage and issuing from the second outlet into the water stream. The outlet tip ends for the outlet tubes are beveled into the direction of flow of the advancing water stream and each beveled tip end may have a notch formed at an extremity to increase turbulence. The first and second outlets are preferably located at maximum distances from each other and from the walls of the water containing equipment.

Title: Optical waveguide having negative dispersion and large Aeff
Inventor: MITCHELL BRIAN EDWARD
IPC: G02B/
Filed: 2000-07-29
Granted: 2001-08-01
Abstract: The invention is directed to a single mode optical waveguide fiber profile that provides relatively large effective area while limiting macrobend loss. The large effective area results from configuring the core of the waveguide fiber to shift propagated light power away from the waveguide center. Macrobend loss, as measured by pin array or 20 nm mandrel testing, is maintained low by means of a power-limiting index depression surrounding the central core region of the waveguide. In addition, low attenuation is achieved and cut off wavelength is controlled to provide a telecommunications operating window in the wavelength range of about 1250 nm to 1700 nm.
