Abstract: The On-Off hook detection circuit will produce the status-detected signal by sensing the voltage level of the telephone line, that is used by audio frequency band communication, the voltage level will be changed by the status of On-hook or Off-hook. According to the status-detected signal in different On-hook and Off-hook situations, the equipment performs the data communication through the adaptive equalization, bit-assignment and gain-distribution in the time-domain and the frequency-domain using the different tables that include the Time Equalizer, Frequency Equalizer, Constellation-encoder and Gain-ratio. Again, for the reason of that the telephone is not in use while the line is in the On-hook status, the equipment could expand the transmission sub-carrier or shift to the band closely to the audio frequency band and, furthermore, to the audio frequency band.

Title: Method for preventing an electrostatic chuck from corroded during a cleaning process
Inventor: TSAI CHENG-YUAN
IPC: C23F4/00
Filed: 1999-06-04
Granted: 2002-09-01
Abstract: The present invention relates to a method for preventing an electrostatic chuck positioned at the bottom of a plasma vacuum chamber from being corroded during a cleaning process. The electrostatic chuck comprises a conductive substrate functioned as a lower electrode in a plasma process, and an insulating layer on the conductive substrate to electrically isolate the semiconductor wafer and the conductive substrate. The cleaning process involves a plasma process in which a fluorine-contained gas is injected into the plasma vacuum chamber to remove the chemical layer on the inner wall of the plasma vacuum chamber. A ceramic shutter made of SiC material is reposed on the electrostatic chuck and a high DC voltage is applied to the conductive substrate and the ceramic shutter which causes the ceramic shutter and the electrostatic chuck tightly stick together due to an electrostatic reaction. By doing so, the fluorine-contained gas cannot corrode the insulating layer under the ceramic shutter through the gap between the ceramic shutter and the electrostatic chuck.

Title: Water saving method and device for quick washing of natural sand
Inventor: JANG R-YANG
IPC: B03B5/62
Filed: 2000-06-05
Granted: 2002-01-01
Abstract: This invention is of a method that treats and removes sludge from natural sand to obtain qualified pure sand through a mechanical device with a special washing mechanism. The main procedure is to guide in an ascending water flow to flush the natural sand and then to cause the sand and sludge separate from each other for the descending velocities of sand and sludge in water vary. The sand will descend and settle while passing through the ascending water flow, while the sludge will be carried away by the water flow and detach from the sand mass. Then the settled sand goes and passes through a screen with high frequency vibration to remove water. The waste water of sludge goes through a settling tank to be processed into an upper and clear liquid, which will be recycled as sand washing water, and a bottom sludge which will be dehydrated as solid mud lump by a mud water remover with the dehydrated water recycled for secondary washing of sand. Thus, the whole treatment is almost with no waste water and becomes a sand washing system of close circuit. (Diagram 1: Water saving method and device for quick washing of natural sand.)
Patent TW-544599-B (TW)
Title: Configurable space-time performance trade-off in multidimensional database systems
Inventor: REDDY VENUGOPAL P
IPC: G06F17/30
Filed: 2000-10-27
Granted: 2003-08-01
Abstract: A multi-dimensional database includes data organized into hierarchical levels. For each level within a dimension, predefined thresholds are set to determine which intersections are precomputed and which are not. The general result is to precompute intersections which take relatively longer to compute at run time, and to not precompute intersections which can be calculated relatively quickly at run time. When multiple dimensions of data are provided, a step-by-step process uses the level threshold for each dimension to determine whether data is to be prestored at an intersection. An odd-even calculation insures that computations performed at run time are relatively efficient. The technique results in good run time response, while not requiring maximum storage or recalculation time for data updates. By adjusting the thresholds at the individual dimension level, response of the multi-dimensional database can be changed as desired.

IPC: G03F1/00
Filed: 2000-09-25
Granted: 2002-01-01
Abstract: A method is for making an integrated circuit on a semiconductor wafer, where the integrated circuit includes circuit features having a desired, relatively small, critical dimension. The method preferably comprises the steps of: designing a reticle including pattern features having a critical dimension to form corresponding circuit features based upon overlap areas defined by a plurality of exposure steps with a shift therebetween so that the circuit features have the desired, relatively small, critical dimension. The designing step preferably includes determining a scaling factor function for relating the critical dimension of the pattern features and the shift to the desired critical dimension of the circuit features and while taking into account that the scaling factor function is also a function of the shift. The method preferably includes steps of fabricating the reticle and using the reticle to make the integrated circuit on the semiconductor wafer based on the plurality of exposure steps. The present invention recognized that the scaling factor is not a single number, but instead is a non-linear function which is also based upon the shift between exposure steps.

Granted: 2003-09-21
Abstract: An optical sensor that includes a light source and a detector is located within a cavity in a polishing pad so as to face the surface that is being polished. Light from the light source is reflected from the surface being polished and the reflected light is detected by the detector. The electrical signal produced by the detector is conducted to a hub located at the central aperture of the polishing pad. The disposable polishing pad is removably connected, both mechanically and electrically to the hub. The hub contains electronic circuitry that is concerned with supplying power to the optical sensor and with transmitting the electrical signal to a non-rotating station. Several techniques are described for accomplishing these tasks. The system permits continuous monitoring of an optical characteristic of a surface that is being polished, even while the polishing machine is in operation, and permits the end point of the polishing process to be determined.
