IPC: G06T7/00
Filed: 1995-06-22
Abstract: PURPOSE: To simplify visual inspection of nonuniformity of transmittance of light due to irregular dimensions of perforations of a perforated plate such as a shadow mask and to improve the inspection accuracy. CONSTITUTION: The shadow mask inspection device 30 compresses a raw picture image picked up by a CCD camera 49 and gradation data of 320×256×14 bits are acquired. These compressed picture image data are given shading correction by being divided by reference data, and noises caused by a light source or the like are thus removed. Nextly, the shading-corrected gradation data are given smoothing-processing, for picture image correction, by a median filter having a 31×31 filter window, and smoothed median data are acquired. Thereafter, standardized data are found by dividing the gradation data by the median data, and a picture image is displayed based on the standardized data, the picture image being displayed in which a grade of the shadow mask is removed and nonuniformity is emphasized.

Title: Data processing method for serial access disk
Inventor: MUTO TOSHIYUKI
IPC: G11B20/12
Filed: 1986-08-01
Abstract: PURPOSE:To surely read a data by arranging 1st and 2nd synchronizing codes while holding a gap,an area writing a data after them and a 3rd synchronizing code after the data respectively to form one block and providing a gap between respective blocks. CONSTITUTION:A disk 10 is driven, synchronization is taken by a synchronizing code SYNC 1 and synchronization is taken next by a SYNC 2, a data mark code is confirmed to read a directory data to seek a dead block. While synchronization is taken by the SYNC 1, when the dead block is arrived, a gap is written after the SYNC 1, and the SYNC 2, a data mark code data area, a CRC, and the SYNC 2 are written sequentially. In such a case, after the SYNC 1, the gap after updating is overlapped onto the gap before the updating and it takes some time when the driver 11 moves from the reading to the writing state and even if the length of gap is changed, the data is synchronized by SYNC 2. Thus, the reading of data is executed accurately.
