Title: Magnification correction for small field scanning
Inventor: ALLEN PAUL C
IPC: G02B17/08
Filed: 1996-03-19
Abstract: Magnification correction for small field scanning of large blanks is provided by adding magnification adjusting elements (lenses 712, 714, 722, 724) to a double pass Wynne-Dyson lens (770) or other type of one-to-one projection lens. The magnification adjusting optical elements include two pairs (710, 720) of low power lenses, one associated with each of the input and output prisms (731, 732) of a Wynne-Dyson lens. Movement of the magnification adjusting optics provides positive or negative magnification as needed to correct for any expansion or compaction of the blank (160) relative to the reticle (120) and hence maintain alignment. Further magnification correction is provided by a small velocity relative movement between reticle (120) and blank (160) by means of a secondary stage in the scan direction. This corrects for any alignment error in the scan direction and may be used independently of the optical correction technique with any type of projection lens.

Title: Produits en feuilles ameliores destines a etre utilises dans un distributeur instantane et procede de formation a partir de rubans etires
Inventor: BAVELY JANE LOUISE
IPC: B65H37/00
Filed: 1996-11-27
Abstract: L'invention se rapporte à un procédé amélioré de formation d'une couche de feuilles superposées, pouvant être utilisées dans un système de distribution instantané. Les feuilles (S10, S11) sont découpées dans des rubans (R10, R11) qui ont initialement des bords essentiellement parallèles à l'axe longitudinal du ruban. Au moins un bord latéral de chaque ruban est étiré de façon à former une partie saillante analogue à un coude, le bord latéral opposé étant soit pratiquement parallèle à l'axe longitudinal du ruban, soit également étiré pour former au moins une partie saillante analogue à un coude sur le bord opposé. Les rubans (R10, R11) sont alors alignés de façon à ce qu'une partie saillante d'un bord s'aligne soit sur le bord essentiellement parallèle d'un ruban adjacent, soit sur une partie saillante du bord latéral d'un ruban adjacent. Après une mise en place progressive, les rubans sont superposés, créant une série de zones voisines prédéterminées à chevauchement plus grand et à chevauchement minimal ou sans chevauchement, de sorte que des rubans successifs soient liés uniquement par l'interaction des faces en contact entre chaque ruban. En superposant plusieurs rubans de cette manière, on forme une couche qui est ensuite pliée pour intercaler les rubans. La pile (75) de rubans intercalés obtenue est découpée dans un sens essentiellement perpendiculaire à l'axe longitudinal des rubans à des intervalles prédéterminés afin de former un bloc (76) de feuilles intercalées individuelles (S10, S11). Le procédé peut être effectué manuellement ou selon un processus de production continu.
