Patent DE-4113027-A1 (DE)
Inventor: SCHNEIDER ECKART
IPC: G03F7/22
Filed: 1991-04-20
Abstract: The description relates to a process and device by means of which grid scales of any length can be reproduced with a grid constant in the  mu m range. A model scale is first imaged continuously in steps on a flexible metal strip coated with a photo-resist. A sensor coupled to the imaging device detects the structures in the exposed photo-resist. Holders for the flexible metal strip on the imaging device and the imaging device bench which can be switched on alternately take further sections of the metal strip in succession into the imaging field by relative movements between the imaging device and the bench. Control signals derived from the sensor ensure the proper phase positioning of the images of the model scale.
Patent DE-4115315-A1 (DE)
Inventor: GRULER MARTIN DIPL ING
IPC: G01C17/38
Filed: 1991-05-10
Abstract: Circles of measurement values (21) which are acquired by means of vehicle-associated magnetic-field-sensing measuring devices and are stored in a matrix memory (18) tend to drift since the measurement data (15) are unavoidably influenced by interference variables. To reduce the storage capacity needed for the data acquisition, it is proposed to subtract a correction value (16), corrected in a control loop, from all measurement data (15) before they are read into the matrix memory (18) in order to stabilise the position of the circle of measurement values (21) formed by measurement data (15). The invention includes methods for obtaining the correction value (16) which reduce complexity. <IMAGE>
