摘要： In an optical information recording/reproducing apparatus for recording/reproducing information on or from an optical disc, a laser beam is focused on the surface of a substrate of the optical disc so that the intensity or a high frequency component of a reflected laser beam is used to detect contaminants on the optical disc surface or a test signal containing a plurality frequency components and recorded on a specified track on the optical disc is reproduced and detected so that the difference between amplitudes of the frequency components is used to detect contaminants on the optical disc surface. Scattering of the laser beam can be prevented and recording/reproducing can be effected with a proper level of laser power.

摘要： The present invention relates to an outline font expanding method and an outline font expanding device each of which can reproduce faithfully the line width of an original outline font. The coordinate system for vector data is defined on the boundaries between dots to create an outline font on the boundaries. The number of dots in the main scanning direction is calculated as a unit change when the outline font is moved by one dot in the secondary scanning direction. A value obtained by dividing the unit change by 2 is added to the coordinate in the main scanning direction of the outline font. while the scanning line is moved dot by dot in the main scanning direction, the intersection of the scanning line and the outline font is obtained at each move position. Thus, the filling range over the scanning line is defined in the main scanning direction. This invention is applicable to a method which fills the inside of an outline font drawn, based on vector data and then forms a dot pattern of a character, symbol, graph, or the like.
摘要翻译：本发明涉及一种轮廓字体展开方法和轮廓字体扩展装置，它们可以忠实地再现原始轮廓字体的线宽。向量数据的坐标系定义在点之间的边界上，以在边界上创建轮廓字体。当轮廓字体在副扫描方向上移动一个点时，主扫描方向上的点数被计算为单位变化。通过将单位变化除以2而获得的值被添加到轮廓字体的主扫描方向上的坐标。扫描线在主扫描方向上逐点移动时，在每个移动位置处获得扫描线和轮廓字体的交点。因此，扫描线上的填充范围被限定在主扫描方向上。本发明适用于基于向量数据填充绘制的轮廓字体的内部的方法，然后形成字符，符号，图形等的点图案。

摘要： This invention relates to an optical disk, in which part of the sectors are reproduction-only sectors and remaining sectors are recording-reproduction sectors. Data and first error correcting codes for the data are recorded in advance in the reproduction-only sectors, and second error correcting codes for data over a plurality of reproduction-only sectors are recorded in advance in other reproduction-only sectors. At data reproduction, only sectors which are unrecoverable by the first error correction codes undergo error correction by the second error correcting codes, and the corrected data with the first error correcting codes being appended are recorded in the recording-reproduction sectors. Later on, when data in sectors unrecoverable by the first error correcting codes are needed, the above-mentioned recorded sectors are read out. Data storage about twice the capacity of the data recording areas is made possible by adopting the PWM (pulse width modulation) recording for the data reproduction-only area and the PPM (pulse position modulation) recording for the recording-reproduction area.

摘要： Disclosed is the powder feeder in which the duty ratio X.sub.T corresponding to the target feed amount Q.sub.T is calculated on the basis of the calibration curve obtained by the feeder calibration which is conducted before the start of powder feed, and the powder P starts to be fed according to the duty ratio X.sub.T, therefore, the actual feed amount can reach to the target feed amount Q.sub.T in a short time (within the time T.sub.1) from the start of powder feed, and the powder P can be fed while controlling the actual feed amount with high accuracy, and further the powder P can be precisely fed even in case of the short time feed for several seconds.

摘要： An error detecting and correcting apparatus having a Galois field arithmetic unit for detecting and correcting errors in code words of a long minimum distance Reed-Solomon error correcting code used in recording/reproducing data to/from media such as an optical disk, by decoding the error correcting code. The apparatus gives a modified syndrome as an input to a generalized decoding procedure for the error correcting code free or erasure correction to obtain an error value as an intermediate value, dividing the intermediate value by the sum of error location numbers to obtain a new intermediate value, adding the sum of the new intermediate values to the product sum of syndromes and expansion coefficients of partial error location polynomial to re-compute the new intermediate value, thus successively computing the new intermediate values, and thereby providing new means to effect the generalized decoding procedure free of erasure correction even when no error location number is known in advance, to make error correction based on a computed error location number executable, along with error correction based on a known error location number.
