Filed: 1999-05-10
Abstract: PROBLEM TO BE SOLVED: To prevent a wiring board or a circuit component from smoking and firing and a switching means from entering a short-circuit mode to break by comparing outputs differentially, and controlling a drive signal generating means for protection when there is a differential output so that no overcurrent flows to a switching means. SOLUTION: When 1st and 2nd switching means Q1 and Q2 are ON, electric power is sent out to the secondary winding ws3 of an insulation type transformer T3. Then when the switching means Q1 and Q2 are on, a load current and a current based upon the self-inductance of an inductor L flow at the same time. A diode D2 operates so that when the switching means Q1 and Q2 are off, fly-back energy accumulated in the inductor L is not discharged from the secondary winding ws3 of the insulation type transformer T3, but sent out to an electric load side through the diode D2. The output voltage obtained between output terminals t1 and t2 depends upon the on duty of the switching means Q1 and Q2.

Filed: 1986-06-04
Abstract: PURPOSE:To reduce printing plate barrel manufacturing cost and dispense with inventory control of the printing plate barrel by enabling a pressure barrel and printing plate barrel to rotate asynchronously and printing different lengths of repeats without changing the diameter of the printing plate barrel. CONSTITUTION:The power of the first gear 10 is transferred to a speed change mechanism 12 through a transmission shaft 13, and at the same time, a rotational speed is changed to allow the power to be transferred to the second gear 14 via a transmission shaft 15. The rotational speed of the gear 14 is conveyed to an idle gear 72, 74 and then to an idle gear 76, 78. This results in the rotation of the first and fourth printing plate barrels 24, 54. The first gear 10 is rotated by an electric motor 11 in accordance with the travel speed of a running web and each pressure barrel is rotated through the first transmission means. In the meantime the rotational motion of the second gear 14 changed at a pre-arranged ratio by the speed change mechanism 12 is conveyed to each printing plate barrel via the second transmission means. Thus each printing plate barrel rotates at a different peripheral speed from each pressure barrel. For the reason, repeats of different lengths from the pattern size of a printing plate are printed.
