Filed: 1999-07-30
Granted: 2001-09-21
Abstract: A conveyor (20, 120, 220, 320) for transporting objects sensitive to electrostatic discharge. In one embodiment, the present invention relates to a slippable roller conveyor (20, 120, 220, 320) with conductive slippable rollers (30, 30') in electrical communication with an electrical ground (60). The slippable rollers (30, 30') preferably have about 10<SP>5</SP> ohms resistance from the outer surface (40) to the inner diameter (34) to ensure that electrostatic charges built up on the conveyed object can flow to ground, yet not flow too quickly. In another embodiment, the roller shafts (35) are supported on highly conductive bushings that provide a path to electrical ground that is preferably less that 10<SP>4</SP> ohms. In yet another embodiment, the roller shafts (35) are driven by a conductive pulley (65) that minimizes the build-up of electrostatic charge as a result of a triboelectric effect with the drive belt (70).

Title: Reduced complexity and increased flexibility modified fast convolution algorithm
Inventor: HELLBERG RICHARD
IPC: H04B14/04
Filed: 1999-10-02
Granted: 2002-01-11
Abstract: The present invention seeks to enhance the above-described modified fast convolution algorithm in order to increase the flexibility of the algorithm. In an exemplary embodiment of the present invention, a folding unit is introduced as a pre-processing stage prior to the IDFT in the receiver. The folding unit adds outer frequency components onto inner frequency components in the frequency domain in order to produce a reduced set of frequency components. In an alternative embodiment, an unfolding unit is introduced as a post-processing stage after the DFT in the transmitter. The unfolding unit expands the set of the set of frequency components by adding translated original components outside the original set. The folding and unfolding processes increase the flexibility of the modified fast convolution algorithm by reducing the number of operations per second that have to be performed for the channel-specific parts of the algorithm. Moreover, since the number of operations per channel decreases, more channels can be treated by a single chip.

Granted: 2001-07-11
Abstract: The cost of production is reduced by effectively utilizing a substrate and reducing testing time. Adjoining two LCD driver chips mounted on a TCP are arranged with their input lead sides and output lead sides arranged opposite to each other, and the input testing terminals and the output testing terminals are commonized. With this arrangement, the mounting pitch of the LCD driver chips is reduced to effectively utilize a substrate, for the achievement of cost reduction. In this case, the input terminals of the same ordinal numbers are arranged so that they receive an electric power or a signal of an identical electric potential as an input when viewed from both ends of the LCD driver chips. Then, both the LCD drivers are concurrently tested by probing at one time by applying an input signal to an input testing terminal common to both the LCD drivers and concurrently measuring outputs from the respective output testing terminals. Cost reduction is achieved by thus reducing the testing time.

Title: Voltage control interface for recursive power control in a plasma reactor
Inventor: BENJAMIN NEIL
IPC: C23C16/52
Filed: 2000-12-22
Granted: 2003-06-21
Abstract: A plasma reactor system with controlled DC bias for manufacturing semiconductor wafers and the like. The reactor system includes a plasma chamber, a plasma generating coil and a chuck including a chuck electrode. The chuck supports a workpiece within the chamber. The plasma reactor system further includes a pair of generators, one of which supplies a radio frequency signal to the plasma generating coil. The second generator delivers a RF signal which to the chuck electrode and acts to control DC bias at the workpiece. Peak voltage sensor circuitry and set point signal circuitry controls the power output of the generator, and a matching network coupled between the generator and the first electrode matches the impedance of the RF signal with the load applied by the plasma. DC bias determines the energy with which plasma particles impact the surface of a workpiece and thereby determines the rate at which the process is performed. This DC bias forms at the surface of the workpiece upon generation of a plasma in the plasma chamber and is affected by the RF signal applied to the chuck electrode. Since power losses within the match network are variable and unpredictable, the peak voltage at the electrode can not be consistently maintained by simply applying a predetermined generator output. By monitoring the peak voltage at the electrode and generating a corresponding control signal to control the generator, a consistent DC bias and corresponding process rate can be maintained.
