Abstract: Dispositifs semiconducteurs a effet de champ et procede de commande du dispositif par des regions d'appauvrissement fusionnees. Le dispositif comprend, en combinaison, une premiere (22) et une seconde (24) jonctions PN espacees entre elles. Des regions d'appauvrissement (36, 38 et 40, 42) associees aux jonctions ont des frontieres deplacees de leurs jonctions respectives en fonction de la concentration de dopage de chaque cote des jonctions. Les jonctions sont espacees entre elles d'une distance qui permet le chevauchement des regions d'appauvrissement (38, 40) positionnees entre elles. En appliquant une polarisation inverse a l'une (22) des jonctions PN, on peut modifier la conductivite du cote (34) de la seconde jonction PN (24) eloignee de la premiere jonction PN (22) par l'effet des regions d'appauvrissement fusionnees.

Abstract: Handwritten and typewritten characters read in one and the same process. 
<??>In the first step, four interleaved images of the character are recorded in a memory (3). Then a preprocessor (4) determines the sort of characters either handwritten or typewritten, on the basis of their respective dimensions. Typewritten characters are enlarged so that they will be better readable owing to an enhanced scanning and stored in a buffer (10), the handwritten characters being first segmented by a geometric separator (9) before their storage in the buffer (10), next a circuit (5) derives the features irrespective of the sort of characters, after which the classification (in 11) takes place by means of learning means (12, 13) dependent on the sort of characters. A results combiner (20) resolves multiple recognitions by a feedback action to the buffer (10). 
<??>An editing device (14) arranges the recognition result in the right format and a final comparator (15) compares the output of the character-reading device to the output of a manual key-entry device.

Abstract: In a system for retrieving data from a recording medium employing MFM or FM encoding forms, a decoding method and circuit employs the technique of delaying the third harmonic of the data signal relative to the fundamental of the data signal by 180 degrees. This delaying is effected by the use of two resonant networks (H, F) each delaying the third harmonic relative to the fundamental by 90 degrees. The delaying technique enables a differentation stage to be eliminated.

Abstract: A data communication system uses a 2-wire transmitter 2 which adjusts the current through the pair of wires 17 between 4 and 20 mA to represent a process variable; this can be sensed by an analog-to-digital converter 70, across a resistor RO, feeding a display 74. A communication device 8 can interrupt the PV analog signalling for digital signalling. Device 8 draws a 16 mA current for 1 bit time, and this is sensed by transmitter 2, which ceases PV transmission. Device 8 then sends 1 or more bytes, by drawing 0 and 16 mA current pulses, which are sensed by transmitter 2. Transmitter 2 can then send data back to device 8 by raising its output to 20 mA, and dropping it to 4 mA for 1 bit time each, then transmitting the data as 1 or more bytes with logic levels 4 and 20 mA. A steady level of 4 mA for a predetermined period t is recognized by either device as the end of digital signalling, and the transmitter 2 resumes its analog PV output
