  • Patent number: 9662874
    Abstract: After the end of a preceding print job, a printing press is stopped, and ink form rollers (6-1 to 6-4) of an ink roller group (6) are thrown off. After that, a printing plate (7) is exchanged with a printing plate (7?) of a next print job, and a blanket (91) mounted on a blanket cylinder (9) is cleaned. The opening amounts of ink fountain keys (4-1 to 4-n) corresponding to the image of the printing plate (7?) of the next print job are obtained. The obtained opening amounts of the ink fountain keys (4-1 to 4-n) are corrected by correction values of the opening amounts of the ink fountain keys (4-1 to 4-n) considering the influence of cleaning of the blanket (91) to obtain corrected opening amounts. In a state in which the opening amounts of the ink fountain keys (4-1 to 4-n) have been set to the corrected opening amounts, a corrected ink film thickness distribution corresponding to the image of the printing plate (7?) of the next print job is formed on the ink roller group (6).

  • Patent number: 6188972
    Abstract: An integrating device includes: a non-volatile memory for storing a value of an integrated running distance of a vehicle; an arithmetic processor for calculating a new integrated running distance by a signal generated at each predetermined running distance and also by the integrated running distance stored in the non-volatile memory; and a display unit for displaying the integrated running distance. The non-volatile memory stores a positive value lower than a predetermined reference value as an initial value of the integrated running distance, and the arithmetic processing means outputs a value obtained when the predetermined reference value is subtracted from the integrated running distance, to the display means as the integrated running distance in the case where a value of the integrated running distance stored in the non-volatile memory is not less than the predetermined reference value.

  • Patent number: 5761074
    Abstract: In one data updating period, an edge pulse signal generator detects an edge of a pulse signal, and generates a one-shot pulse signal. A digital filter performs digital filter processing of the one-shot pulse signal, and outputs one frequency data. An averaging circuit adds k (positive integer) frequency data output from the digital filter in k data updating periods, and calculates average value data as an average value of the k frequency data. Furthermore, the averaging circuit sets a period in which the value of the average value data is held to be a constant value to be k times the data updating period. A PWM conversion circuit converts the average value data into PWM data by pulse-width modulation.
