Title: Character recognition device
Inventor: ISHIDERA EIKI
IPC: G06K9/62
Filed: 1995-06-05
Abstract: PURPOSE: To accurately reject an error in character recognition by calculating the reliability of a recognized result by using the distance value and distance ratio of a recognized character candidate and controlling recognition based upon the reliability. CONSTITUTION: A distance value calculating part 12b reads out a feature obtained from a feature extracting part 12a and a reference feature stored as a reference pattern from a character recognition dictionaray storing part 12c, calculates a distance between the feature of the input character and the feature of the reference feature and finds out the character code of the input character pattern and the distance value in the ascending order of distance values. A distance ratio calculating part 13b reads out the character code and the distance value and divides the distance value of each candidate by the distance value of a 1st candidate to find out the distance ratio of each candidate.  A reliability calculating part 13c reads out the distance value of each candidate and finds out the reliability of a character recognition result based upon the distance ratio of each candidate and a recognition control part 14 controls recognition processing based upon the found reliability. Even when the distance values of recognition results of respective candidate characters are not similar, the recognition can be rejected.

Title: X-ray aligner, aligning method, and fabrication of device
Inventor: WATANABE YUTAKA
IPC: G03F7/20
Filed: 1993-06-30
Abstract: PURPOSE:To measure the intensity distribution of exposure in a short time with such accuracy as allowing fluctuation in the exposure by controlling the exposure of X-ray at each position within an exposing region based on the correspondence of the intensity distribution of X-ray to the exposure distribution within the exposing region and the intensity of X-ray monitored at the time of exposure. CONSTITUTION:A resist is exposed and to determine the ratio of residual film and then the ratio to an optimal exposure, i.e., the distribution of exposure, is determined over the entire exposing region. The intensity distribution of exposure is then determined with such accuracy as allowing fluctuation in the exposure based on the output from an X-ray detector 10 obtained upon rotation of a mirror 3. Subsequently, an optimal exposure time is calculated at each point within the exposing region and the speed of a shutter 5 within the exposing region is determined by a shutter control unit 11 such that the shutter 5 is opened for a correct exposing time to exposing the resist. This constitution allows measurement of the intensity distribution of exposure in a short time resulting in the elimination of fluctuation in the exposure.
