  • Patent number: 7019927
    Abstract: In an apparatus for recording and reproducing a burst-like digital information signal, a method capable of predicting the time of occurrence of a header indicating the head of the first data of a digital information signal during its reproduction from a recording medium. The digital signal includes a plurality of data blocks each including a header indicative of the head of the block, and each header includes the address of the block. During recording of the digital signal on the recording medium, a plurality of headers which are substantially the same as the headers of the data blocks and including addresses having given relations with the addresses of the data blocks are inserted in a clock regenerating signal recorded before the digital signal for regenerating the clocks for the signal. The headers are inserted at a period equal to the length of each data block so as to be synchronized with the headers of the data blocks.

  • Patent number: 6393151
    Abstract: 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.

  • Patent number: 5982192
    Abstract: A high speed bus circuit system according to the present invention includes a bus having alternately connected resistors and transmission lines, and integrated circuits. Each of the resistors has a predetermined resistance value. The transmission lines are mounted on print circuit boards. The bus is connected in a loop form as a whole. Each of the integrated circuits has a driver and a receiver. The driver and receiver are connected to respective one of the resistors. As a result, DC power dissipation in the terminal resistor of the bus circuit is suppressed. In addition, high speed signal transfer causing less waveform distortion is made possible.
