摘要:
An apparatus for recognizing visual patterns of handprinted characters or the like by means of an optical character reader which reads the patterns by a so-called outermost point method. While tracing the contour of the pattern stored in a two-dimensional memory, the distances from the starting point of the tracing and the integrated values of the coordinates of the points traced on the contour from the starting points are simultaneously obtained successively to extract outermost points for the series of contours. According to this outermost points, the contours are segmented into the convex line segments, concavity line segments and hole segments and the corresponding parameters of features of each segment are detected. Simultaneously, the convex line segment of which is shorter than a predetermined length is rejected and the remaining segments are subjected to matching operation in accordance with preliminarily prepared dictionary, thereby making a decision as to the pattern's identity.

Provided is a technology capable of reducing parasitic capacitance of a capacitor while reducing the space occupied by the capacitor. A stacked structure is obtained by forming, over a capacitor composed of a lower electrode, a capacitor insulating film and an intermediate electrode, another capacitor composed of the intermediate electrode, another capacitor insulating film and an upper electrode. Since the intermediate electrode has a step difference, each of the distance between the intermediate electrode and lower electrode and the distance between the intermediate electrode and upper electrode in a region other than the capacitor formation region becomes greater than that in the capacitor formation region. For example, the lower electrode is brought into direct contact with the capacitor insulating film in the capacitor formation region, while the lower electrode is not brought into direct contact with the capacitor insulating film in the region other than the capacitor formation region.

Method and apparatus for controlling the cooling of a hermetic type control box accommodating therein electronic apparatus by means of a cooling system. A cooling member of the cooling system is disposed at an upper portion of a hermetically closed chamber in which the electronic apparatus is housed. On the basis of measurements of intra-box temperature and extra-box temperature, control is so performed that the intra-box temperature is maintained higher than the extra-box temperature by a predetermined value when the cooling is being effected within the control box by means of the cooling system.
摘要:
A method for character reading requiring no character segmentation, which method effects required character recognition by the steps of subjecting a given string of character patterns to continuous scanning to produce either a local feature vector at each of the intersections of rows and columns of character patterns or a global feature vector for each of the columns formed in consequence of the scanning, linearly consolidating either or both of the feature vectors to obtain a lower dimensional vector in new feature axes and continuously matching the vectors with the standard ones set in advance.

Provided is a daily inspection process for making a daily inspection of a driving system having a main machine and a plurality of auxiliary machines. The driving system is so constructed that the main machine is started only after a plurality of starting conditions including correct functioning of the auxiliary machines are fulfilled. According to the inspection process of the invention, the plurality of starting condition are inspected sequentially in such a manner that, when the failure in one of the starting conditions is detected, the inspection proceeds to the next step after locking the main machine against the start up, so that the plurality of starting conditions are checked sequentially without suspension, whereby all of the failed conditions are detected in a single inspection operation.

In a case in which handwritten character recognition such as online handwritten character recognition is implemented, simple and high performance character recognition by which transformation such as remarkable transformation and rotation is able to be treated and which recognizes an input that is written in a single stroke such as kaisho-writing, is provided. Because of this, the present invention performs: capturing an input handwritten character with parameter representation for each stroke and applying a polygonal approximation to each stroke; assuming each polygonal line segment approximated by the polygonal approximation to be vector that reaches an end point from a start point, and obtaining an angle between an axis that becomes a reference and each line segment as a polygonal line segment angle sequence; obtaining an exterior angle sequence of vertices of the obtained polygonal line segments; making a sum of exterior angles of the same sign, where the same sign of plus or minus in the exterior angle sequence continues, to be a winding angle sequence; extracting a global feature according to each obtained sequence and a localized or quasi-localized feature in each curved portion divided corresponding to the winding angle sequence, hierarchically and divisionally; and performing the character recognition by comparing the extracted result with a template of an object character for recognition that is provided in advance.

Disclosed is a novel semiconductor integrated circuit device for use in a color VTR (Video Tape Recorder). Concretely, the semiconductor integrated circuit device comprises a substantially rectangular semiconductor chip which has a principal surface, a luminance signal processing unit and a color signal processing unit which are disposed at the positions of the principal surface opposing to each other, and a semiconductor region which is provided in the interspace of the principal surface between the luminance signal and color signal processing units opposing to each other and which is supplied with a bias stable A.C.-wise. Further, the semiconductor region is located substantially at the central portion of the semiconductor chip and is extended so as to intersect with one set of opposing sides of the rectangular semiconductor chip.

A fish is bred in a transparent basin, into which water to be tested is supplied. A light source and a television camera are arranged in such a manner that images of the fish are taken by the camera as a silhouette. From the thus obtained fish images, the frequency distribution of the gravity centers of the fish images in the direction of the depth of water are obtained. The abnormality of the behavior of the fish is detected by comparison of the obtained frequency distribution with a reference distribution provided in advance.
