Title: Bias method and circuit for distortion reduction
Inventor: APARIN VLADIMIR
IPC: H03F1/00
Filed: 2002-04-18
Granted: 2003-11-21
Abstract: The present invention provides a technique for selective cancellation of the 2nd-order or 3rd-order nonlinearity of a transistor. Any nonlinearity is a function of the bias voltage of a transistor. In many cases, this function is such that, at a particular bias voltage, nonlinearity is zero. The invention provides a bias circuit that generates the optimum bias voltage for a transistor at which its selected nonlinearity is zero. Mathematically, the nonlinearity can be represented by a sum of multiple components where some components have negative sign. The components are proportional to the DC currents of the transistor at bias voltages differing by a small amount. The bias circuit includes bias transistors that are scaled versions of the main transistor. Each bias transistor generates a DC current representing one of the components. The currents are combined according to the signs of the respective components to form a DC signal proportional to the selected nonlinearity. A feedback circuit senses the DC signal and generates the bias voltages of the bias transistors that force the DC signal to be zero. One of the bias voltages is applied to the main transistor resulting in cancellation of its selected nonlinearity. The system may be readily implemented using the integrated circuit technology such that the transistors of the bias circuit are closely matched to each other and to the main transistor. The distortion cancellation effect provided by the present invention exhibits low sensitivity to variations in the transistor processing and operational temperature.

Title: Liquid crystal display
Inventor: IKENO HIDENORI
IPC: G02F1/1335
Filed: 2002-08-19
Granted: 2004-04-11
Abstract: In a liquid crystal display, a liquid crystal layer is sandwiched between a lower substrate on which interconnections and thin film transistors are formed and an opposite substrate so arranged as to face the lower substrate. A reflection area in which a reflection electrode is formed and a transparent area in which a transparent electrode is formed are provided, and a common electrode is formed on the opposite substrate. As a voltage is applied between the reflection electrode 18 and the transparent electrode and common electrode, the liquid crystal layer is driven. A potential difference between the drive voltage applied to that surface of the lower substrate which contacts the liquid crystal layer and the drive voltage applied to that surface of the opposite substrate which contacts the liquid crystal layer is made lower in the transparent area than in the reflection area by capacitive division of electrostatic capacities of the transparent area and the reflection area. This maximizes the luminance in reflection mode as well as transmission mode, so that the alignment of liquid crystal molecules is not disturbed even around the boundary between the reflection area and the transparent area.

Inventor: CRADDOCK DAVID F
IPC: G06F9/46
Filed: 2002-09-19
Granted: 2004-04-11
Abstract: A distributed computing system having (host and I/O) end nodes, switches, routers, and links interconnecting these components is provided. The end nodes use send and receive queue pairs to transmit and receive messages. The end nodes use completion queues to inform the end user when a message has been completely sent or received and whether an error occurred during the message transmission or reception process. A mechanism implements these queue pairs and completion queues in hardware. A mechanism for controlling the transfer of work requests from the consumer to the CA hardware and work completions from the CA hardware to the consumer using head and tail pointers that reference circular buffers is also provided. The QPs and CQs do not contain work queue entries and completion queue entries respectively, but instead contain references to these entries. This allows them to be efficient and constant in size, while the work queue entries and completion queue entries themselves can vary in size, for example to include a variable number of data segments. Additionally, several mechanisms are provided to improve the overall efficiency of this process under different memory configurations.

Granted: 2004-05-21
Abstract: A field emission display device (1) includes a cathode plate (20), a resistive buffer (30) in contact with the cathode plate, a plurality of electron emitters (40) formed on the buffer, and an anode plate (50) spaced from the electron emitters. Each electron emitter includes a rod-shaped first part (401) and a conical second part (402). The buffer and first parts are made from silicon nitride. The combined buffer and first parts has a gradient distribution of electrical resistivity such that highest electrical resistivity is nearest the cathode plate and lowest electrical resistivity is nearest the anode plate. The second parts are made from niobium. When emitting voltage is applied between the cathode and anode plates, electrons emitted from the electron emitters traverse an interspace region and are received by the anode plate. Because of the gradient distribution of electrical resistivity, only a very low emitting voltage is needed.
