    摘要: The method and apparatus for startup control of a polyolefine polymerization reactor of the present invention determines an olefine feed rate based on a reaction amount set by the heat balance within the polyolefine polymerization reactor, a reaction balance amount calculated from its unreacted amount and dynamic compensation amount, and the olefine concentration within the polyolefine polymerization reactor. Due to this, model errors are reduced, and the practical application of feed-forward control is possible.

    摘要: An AC driving type of display apparatus such as a matrix type liquid crystal display apparatus, which is adapted to prohibit the application of the scanning voltage upon at least one of the row electrodes for a given period so as to switch the repetition period of the scanning voltage to be applied on at least one of the row electrodes into the integral multiple of the original repetition period. Further, it is adapted to switch the period of the polarity inversion of the driving voltage to be applied upon the picture element in accordance with the repetition period of the switched scanning voltage. Further, the complete AC driving operation may be effected, for example, even in a case where the signal voltage at the first repetition period of the scanning voltage is different from the signal voltage at the second repetition period.

    摘要: An improved row electrode driving circuit can drive a matrix type display apparatus without necessitating digital signals transmitted between partial row electrode driving circuits. Each of the partial row electrode driving circuits is allocated with a number. In each of the partial row electrode driving circuits, shift register shifts a pulse signal to sequentially output it from a plurality of outputs. At each time when a predetermined number of clock pulses have been counted, a count signal is produced. When the shift direction is set to the upper direction, a signal indicating the allocated number is produced. When the shift direction is set to the lower direction, a signal indicating a number which is obtained by subtracting the allocated number from a specified number is produced. When this number and the clock pulse count number satisfy a predetermined relationship, the pulse signal is output.
