IPC: H04N7/173
Filed: 1988-08-29
Abstract: PURPOSE:To quicken the data compression coding processing of a picture data by switching the access to two work memories in a memory area having a capacity corresponding to a row by a coding unit in the case of applying block coding to a picture data alternately. CONSTITUTION:While a decode processing of a received picture data is applied to one of two memory areas of a work memory 25 in the 'picture display processing mode', the picture data finished for the decode processing already stored in the other memory area is converted into a data and written in a picture memory 28. Thus, the decode processing and other data conversion processings or the like are advanced simultaneously to reduce the picture display processing time. Similarly, a picture data is read from the picture memory 28 in the 'data compression coding processing mode', the data written already in the other memory area is subject to data compression by block coding while the data is converted and written in one memory area of the work memory 25. Thus, the data compression coding processing time is reduced.

Title: Automatic production system for recognizing dictionary
Inventor: MATSUURA TOSHIO
IPC: G06K9/68
Filed: 1987-08-28
Abstract: PURPOSE:To automatically judge an accurate feature for production of a recognizing dictionary by shifting vertically and horizontally the areas whose feature should be extracted to obtain the variance of data. CONSTITUTION:An unknown picture data reading part 1 stores temporarily the features of each grid area into a feature data storing part 21 by the addresses of an address setting part 10. At the same time, these grid areas are slightly shifted vertically and horizontally for acquisition of the feature data. These feature data are also stored in the part 21. A data comparison part 22 compares the data stored in the same grid with each other to detect the direction where the segments exist stably as data when viewed with the grid areas shifted slightly, the direction where no segment exists, and the direction where the segments are detected and sometimes not detected. Thus the stable features are decided when the thorough coincidence is obtained between the presence or absence of the segments, and the unstable features decided when no said coincidence is obtained. These features are stored in a recognizing dictionary 4 via a dictionary data storing part 32.

Title: Sample for measuring transmittance, and preparing method thereof
Inventor: JINBO HIROKI
IPC: B32B17/00
Filed: 1994-09-08
Abstract: PURPOSE: To enable highly accurate measurement of transmittance by a method wherein the surface roughness of a ground surface of an optical material of which two opposite surfaces are ground is made a specific value or below. CONSTITUTION: A sample is prepared generally by a method wherein a part of an optical material to be evaluated is cut out in such a shape as to be put in a sample chamber of a spectrophotometer and two opposite surfaces in the direction of thickness are ground optically by an abrasive sold on the market. Surface roughness is caused herein by the height of the indentation of each optically ground surface, residual impurities of a cutting material, the abrasive and the like used at the time of preparation of the sample and a structural defect due to a residual stress generated by machining. These factors lower the spectral transmittance of the optical material.  In preparation of the sample of the optical material, therefore, the sample is pre-ground so that the surface roughness rms = 10Å approx. be obtained, and then the surface roughness is made to be rms =10Åor below by an SiO2 abrasive. Thereby execution of highly accurate measurement is enabled even in measurement of internal transmittance in a short wavelength range of 300nm or below wherein the light-source intensity of the spectrophotometer lowers.
