Inventor: KELLEY STEPHEN HARLOW
IPC: H03F1/30
Filed: 1982-01-25
Abstract: Une source de tension de reference a espace inter-bandes independante de la temperature utilise des transistors bi-polaires (12 et 14) polarises avec des densites de courants emetteurs differentes. Des condensateurs commutes (28 et 34) sont utilises pour entrer Vbe et (Alpha)Vbe des transistors (12 et 14) (tensions PTC et NTC, respectivement), dans un amplificateur operationnel (42) pour obtenir une tension de reference VREF proportionnelle a la somme des tensions PTC et NTC. La selection appropriee du rapport des condensateurs commutes (28 et 34) rend la tension de reference (VREF) sensiblement independante de la temperature. Dans une forme modifiee de la reference (10), l'amplificateur de reference (22) est actionne par un amplificateur operationnel a auto-zero (42) qui utilise des techniques de condensateurs commutes et un condensateur integre (44) pour obtenir la fonction de remise a zero automatique.

Abstract: An optical information processor records predetermined information along a track on a recording medium through the irradiation of a light beam intensity-modulated in accordance with the predetermined information. A tracking signal (11) obtained when the light beam traces the track, is compared with first and second preset values (E 1 , E 2 ) which define a predetermined range. When the tracking signal departs from the predetermined range, the intensity modulation of the light beam or the recording operation is stopped, thereby preventing data destruction which otherwise occurs due to the digression of the light beam from the track.

Abstract: The display of line graphics such as design drawings or land registry maps on a television monitor is considerably improved compared with known methods by the fact that the graphics for display are prepared in a black-white bit matrix which is much finer, preferably 4 x 4 times finer, than the raster which can be displayed on the monitor. From this matrix, rectangles consisting for example of 4 consecutive points on 4 lines one above the other are grouped together to form a "super pixel", the gray scale value of which corresponds to the average of the black-white values of the combined individual pixels of the group. <IMAGE>
