Title: Line narrowing apparatus with high transparency prism beam expander
Inventor: DAS PALASH P
IPC: H01S3/08
Filed: 1999-10-01
Granted: 2001-06-23
Abstract: A grating based line-narrowing apparatus having a prism beam expander with at least four prisms. Each prism is positioned at an incidence angle between 67 and 71 degrees. A single layer coating of high refractive index, robust material, such as Al2O3, is applied to the hypotenuse face of each prism, providing an efficient, anti-reflection coating. In a preferred embodiment the incident angle of the four prisms are each at about 68.2 degrees. The laser of the preferred embodiment has similar line narrowing efficiency and bandwidth as that for a laser with a 3 prism, ideal multi-layer anti-reflection coated beam expander. The primary benefit of the new four prism arrangement is that the prism coatings should be much less expensive and have greatly increased durability. Applicants have tested the new prisms for 30 million, 10 ml pulses in air with no noticeable degradation. No present day dielectric multi-layer stack coating could survive such exposure.

Inventor: BOGUCKI-LAND BOGDAN
IPC: D02H3/00
Filed: 1999-09-30
Granted: 2001-09-01
Abstract: In a procedure for the provision of pattern warps, different threads 12 are pulled off by a rotating thread guide from a circulating thread creel 7 circulating synchronously therewith. The threads are laid off on parallel transport bands oriented axially around the circumference of a non-rotating drum. At predetermined times unneeded threads 12 are connected to the thread guide 11 via a clamp and cut between the clamping point 19 and the drum. Upon renewed demand, the free thread ends 22 are held stationary and the clamp is opened. In a warp-knitting machine in which this procedure can be carried out, every thread guide 11 is provided with an orbiting clamping point 19. A cutting arrangement 20 serves for cutting the threads 12 between the clamping point 19 and the drum 1. On the machine frame there is provided a stationary holding arrangement 21 for the free threads ends. In this manner it is possible to create a plurality of different patterns in a relatively short time.

Title: Semiconductor laser diode
Inventor: YOO TAE-KYUNG
Filed: 1999-10-29
Granted: 2001-06-23
Abstract: Disclosed is a semiconductor laser diode which allows the emission of a laser beam of a narrow width even with a wide electrode area and a wide laser waveguide. A specular surface area capable for total reflection is formed to reduce an outlet area through which an actually utilized laser is emitted, thereby bringing about a decrease in the effective width of a laser waveguide as well as an increase in the electrode area of the diode which can be, in consequence, operated at a low operation current with a low operation resistance. Thus, the totally reflective specular surface can be fabricated without conducting the complicated high reflection coating, giving rise to a great increase in laser properties and productivity.

Title: Long-life traveling spark ignitor and associated firing circuitry
Inventor: SUCKEWER SZYMON
IPC: H01T13/50
Filed: 2000-06-16
Granted: 2002-10-11
Abstract: An ignitor and associated electronics for igniting a combustible mixture in a cylinder of an internal combustion engine are described. The ignitor includes at least two spaced-apart electrodes that define a discharge gap. The space between the electrodes is substantially filled with a dielectric material. The dielectric material is spaced-apart from at least one of the electrodes to provide an air gap over which an initial voltage breakdown between the electrodes will occur. The air gap serves to vary the location of the initial breakdown and as a barrier to a short circuit between the electrodes due to carbon and/or metal deposit buildup on the dielectric material. The associated electronics provide a first potential between the electrodes that generates a plasma between the electrodes. Then the volume of the plasma is increased by the application of a second potential that creates a current through the plasma. The plasma, as well as the current passing through, is swept outward due to the interaction of Lorentz and thermal expansion forces with the plasma. Also described are relative orientations of the electrodes that lead to greater plasma formation.

Title: Apparatus and method for synchronization of multiple data paths and recovery from lost synchronization
Inventor: KOEHLER JEFFREY A
IPC: H04L12/56
Filed: 2000-07-25
Granted: 2003-03-01
Abstract: A system and method for transferring data from a source to a destination are described. Data packets are split into multiple data packet portions and are transferred in parallel over parallel data streams or pipes to grouping circuitry where they are recombined into full data packets. Each packet portion is assigned a synchronization code and a pipe state machine state. The grouping circuitry reads individual packet portions from the parallel streams and analyzes the synchronization codes and the state machine states to determine if the individual packet portions were generated from the same packet. If so, they are recombined into a full packet and are forwarded to the destination. If not, an error is detected. The grouping circuitry automatically realigns the data streams to recover synchronization without the need for any feedback to the individual streams to correct the error.

Abstract: A DC-to-DC converter has a pulse width modulator (PWM) and a hysteretic (ripple) modulator. For low current loads, the hysteretic modulator is selected; for high current loads, the PWM is selected. A mode selection switch senses the polarity of the switched output voltage at the end of each switching cycle. If the polarity changes from one cycle to the next, the mode may be instantly changed to the other mode. Counters are used to record the polarity at the end of each cycle and switching from one mode to another can be delayed by the counters to prevent changing modes based on spurious output voltage fluctuations.
