Filed: 1994-01-27
Abstract: PURPOSE:To immediately sense a malfunction of an illuminance unevenness by providing means for measuring an intensity distribution of an exposure light during real exposing of a wafer. CONSTITUTION:When an exposure operation of one chip exposure area on a wafer 13 is started, a reticle stage 9 and a wafer stage 14 are cooperatively moved in a direction perpendicular to an illuminating direction of an illumination light 7, scanned on a luminous flux of the light 7, and a pattern on a reticle 8 is started to be transferred on a surface of the wafer 13. A photosensor 10 detects the flux of the light 7 during transferring to sequentially measure illuminances corresponding to positions at each predetermined sampling time interval, and its each illumination data is Ui. The illuminance of the light 3 is sequentially detected by an illuminometer 5 at the same time as the time for detecting the illuminance, and its each illuminance data is Li. In order to remove flicker of an illumination light source and influence of aging change of the illuminance, when each illumination ratio value Ii is represented by Ii = Ui/Li, an illuminance distribution curve of the light 7 of the Ii is obtained by executing one exposure operation.

Title: Data imprinting camera
Inventor: KAGECHIKA TAKASHI
IPC: G03B17/24
Filed: 1978-01-27
Abstract: PURPOSE: To obivate the occurrence of double exposure by providing a locking means which locks the display of a display part so that the display in the display part is not changed during data imprinting period.  
     CONSTITUTION: When a display signal C is outputted after a memory lock signal B, this display signal C is inputted to a driver 14. When this display signal C is inputted to the driver 14, the driver 14 goes ON and therefore a display part 15 is lighted and the data having been stored in a memory circuit 12 is displayed. This data is then imprinted on a photographic film. Hence, even if the contents of a counter 11 changes, the display does not change during the data imprinting period and therefore double exposure of data characters may be prevented.

IPC: G06F3/038
Filed: 1989-01-17
Abstract: PURPOSE:To eliminate the repetition of an operation where a mouse is moved and held up to be set again at its original position, then moved again in order to input the information on a large shift in the single direction by providing a holding means which holds the direction information received from a sensor part. CONSTITUTION:A sensor part 1 supply the moving direction information on a mouse to a holding means 2 and a selection means 4 via a signal line 11 and also supplies the shift value information to the means 2 and a process part 5 via a signal line 12. Then a direction information fixing instruction means 3 supplies the signals to both means 2 and 4 to acquire the valid direction information fixing instruction. Thus the means 2 holds the moving direction information received from the line 11 and supplies it to the means 4 via a signal line 21. At the same time, the means 2 selects the moving direction information received from the means 4 and the line 21 and supplies it to the part 5. Thus it is possible to input the necessary shift value with the movement carried out in a free direction after moving once the mouse in its original moving direction in case the information on a large shift of the single direction is inputted. Then the troublesome operations can be omitted.
