    摘要: An improved fork lift truck control system using a microcomputer, which comprises a sensing unit including a first sensor for detecting a lift height of a fork above its lowest position and a second sensor for detecting a tilting angle of an upright with respect to a neutral position of the upright including an input interface circuit for interfacing the sensing unit and control unit which has: (a) a lifting height counting circuit which counts the number of pulses produced on a basis of two photo-converted electrical signals fed from two photocouplers constituting the first sensor, the signals having a phase difference of 90.degree. from each other, so that an accurate measurement of the lifting height of the fork can be made; (b) an analog-to-digital converter which produces a bit string according to an output signal from the second sensor; and (c) an abnormal detection facility which detects a defective analog-to-digital converter and second sensor by comparing the bit string presently outputted from the analog-to-digital converter with each of predetermined bit strings that would be produced if the analog-to-digital converter operates normally.

    摘要: In a video signal reproducing apparatus having a cathode ray tube in which at least one electron beam is made to scan a screen in line-scanning and vertical directions while the intensity of the beam is modulated to establish the brightness of a video picture to be displayed on the screen, and in which bright picture portions are represented by respective high level portions of a video signal defined between rising and falling edges extending from low level signal portions representing contiguous dark picture portions; a waveshaping circuit receives the video signal and acts thereon to provide a compensated video signal in which the width of each high level portion between the respective rising and falling edges is increased, the compensated video signal is employed to control the intensity of the electron beam, the rising and falling edges of each high level portion of the video signal are detected to provide a beam velocity modulation signal with respective positive and negative peaks by which the scanning velocity of the beam in the line-scanning direction is modulated, and the positions of such positive and negative peaks are shafted, relative to the corresponding peaks of a differentiation of the video signal, in the directions toward the adjacent low level signal portions of the compensated video signal.

    摘要: When recording operation is stopped due to, for example, unexpected interruption of electric power supply in the course of the recording operation on a real time basis, a technique of repairing a moving picture and sound data recorded on a recording medium until the recording is stopped, to thereby restore management information data which enables random access and special reproduction is provided. A video/audio/management information multiplexing means is so implemented as to generate data required for generating management information data for allowing random access to the recording medium and effectuating special reproduction of the recording medium, for thereby multiplexing the data required for generating the management information data, encoded video data outputted from a video encoding means and encoded audio data outputted from an audio encoding means.
