Title: Method of and device for scanning carrier
Inventor: HAMER RENE HANDRIK
IPC: G11B19/247
Filed: 1988-06-21
Granted: 1998-04-22
Abstract: A method and device are revealed for scanning a radiation-sensitive layer (2) of a rotating carrier (4) with a constant linear velocity by means of a radiation beam (5) which is directed towards the carrier (4) by an optical system (6) which is radially movable relative to the carrier (4). A velocity-pulse generator (10) generates clock pulses (Ps) of a frequency (fs) proportional to the angular velocity of the carrier (4). A clock generator (25) generates clock pulses (Pk) of constant frequency (fk). In response to every clock pulse (Pk) a sum value (Sw) is corrected by a first correction value (DEC). In response to every velocity pulse (Ps) the sum value is corrected by a second correction value (INC) having a sign opposite to that of the first correction value. The angular velocity (W) of the record carrier is controlled to a value for which the average of the sum value (Sw) remains constant. The ratio between the second (INC) and first correction value (DEC) is maintained at a value which is proportional to the distance (Xr) between the point of incidence of the radiation beam (5) on the carrier and the centre of rotation. Thus, scanning is effected with a constant linear scanning velocity.

Title: Method for polymerization of epoxide compounds
Inventor: BOETTCHER AXEL
IPC: H01L23/31

Granted: 1997-02-11
Abstract: The invention relates to a method for polymerization using a Lewis base which accelerates the reaction. An epoxide compound, e.g. a diglycidyl ether of bisphenol-A is mixed with a metal complex compound of general formula MLxBy or M [SR]xBz and heat energy is supplied. M is a metallic ion, L is a ligand, SR is an acid residue ion of an inorganic acid, B is a Lewis base, x is a natural number analogous to the valency of the metallic ion, y is a natural number and z is a natural number greater than 6.
