Abstract: A method of fabricating an EEPROM includes the steps of sequentially forming a gate oxide layer, first polysilicon layer, first insulating layer, second polysilicon layer and insulating layer on a semiconductor substrate, etching the insulating layer and second polysilicon layer using a mask to form a gate mother pattern for forming a gate pattern, forming a second insulating layer on the overall surface of the substrate, etching back th second insulating layer to form a sidewall insulating layer on the sides of the gate mother pattern and exposing the first polysilicon layer, forming a third polysilicon layer on the overall surface of the substrate, dry-etching the third polysilicon layer to expose the top of the gate mother pattern, thereby forming a polysilicon sidewall connected to the sidewall insulating layer of the gate mother pattern and the first polysilicon layer, and performing ion implantation using the gate electrode to form source and drain regions in predetermined portions of the substrate.

Title: An hdtv compression system
Inventor: RAYCHAUDHURI DIAPNKAR
IPC: H04N5/44

Granted: 1999-12-15
Abstract: Apparatus for encoding/decoding a HDTV signal for e.g., terrestrial transmission includes a compression circuit responsive to high definition video source signals for providing ierarchically layered codewords CW representing compressed video data and associated codewords T, defining the types of data represented by the codewords CW. A priority selection circuit, responsive to the codewords CW and T, parses the codewords CW into high and low priority codeword sequences wherein the high and low priority codeword sequences correspond to compressed video data of relatively greater and lesser importance to image reproduction respectively. A transport processor, responsive to the high and low priority codeword sequences, forms high and low priority transport blocks of high and low priority codewords respectively. Each transport block includes a header, codewords CW and error detection check bits. The respective transport blocks are applied to an forward error check circuit for applying additional error check data. Thereafter the high and low priority data are applied to a modem wherein they quadrature amplitude modulate respective carriers for transmission.

Title: Method and device for determining saline aerosols "in situ"
Inventor: PASCU CONSTANTIN
IPC: G01N15/06
Filed: 2003-11-20
Abstract: The invention relates to a method and a device for "in situ" determining the saline aerosols in natural or induced therapeutical environments. According to the invention, the method consists in determining the conductivity of a solution obtained by fine barbotage, in tri-distilled dis-oxygenized water, of the air loaded with saline aerosol, at a controlled flow, for a period ranging between 10 and 60 min, by means of a conductometer. By the extrapolation on the standard curve of the conductivity value, there is obtained the NaCl concentration for a given volume of solution, and by means of the conversion tables or by calculations, there is established the air saline load expressed in mg/m3. According to the invention, the device comprises a saline air aspiration funnel (1), an extension (2) for carrying out a controlled flow vacuum, frit (3) wherethrough there passes the saline air, into the barbotage area (4), a conductive electrode (5) comprising a built-in temperature compensating electrode, both being coupled to a digital conductometer, by means of the connection cable (6), a buffer system (7) for supplying tri-distilled water, for maintaining a constant volume of 10cm3 solution, and a rubber stopper (8) for sealing the system.
