Title: Error processing method for voice code data in qpsk system and its device
Inventor: HATTORI TAKESHI
IPC: H04L27/22
Filed: 2001-02-09
Abstract: PROBLEM TO BE SOLVED: To provide the error processing method and device of voice code data in a QPSK system capable of improving the deterioration of voice quality when any error is generated by using data which are judged to be close to normal data as the conversion data of error voice code data. SOLUTION: In a digital communication system for performing radio communication by modulating voice code data by a QPSK system, when any data error is detected by a base band processor 2, an error symbol detector 5 identifies an error symbol as the minimum unit length, and a conversion data discrimination processor 6 selects symbol data whose phase is the second closest from the phase quantity of the symbol, and a voice code data converting part 7 performs data conversion. Thus, it is possible to acquire the data approximating to the normal data with high probability, and to minimize the deterioration of the voice quality when any error is generated.

Inventor: KOPLEY THOMAS EDWARD
IPC: H01L21/761
Filed: 2001-03-01
Abstract: PROBLEM TO BE SOLVED: To reduce a leak current from an active region to a filed oxide film region in an image sensor circuit or the like. SOLUTION: In a manufacturing method for providing insulation (isolation) between the adjacent regions of an integrated circuit (10), guard layers (40, 68, 72, 88, 90, and 128) are provided on a field edge that is the interface between field oxide film regions (30, 54, and 92) and diffusion regions (14, 26, 52, 86, and 96) where dopant is introduced.

The transition strips obstruct current leakage from the active filed to the field oxide film region. In one embodiment, the active region is an active region diode that is used for forming the pixel of an active pixel sensor(APS). The guard layers are biased to additionally obstruct the current leakage during circuit operation.
