Abstract: PURPOSE:To feed a printing ribbon only when actually printing, by a method wherein the operation of an idler for coupling a driving force between a driving wheel rotated in response to the movement of a carrier and a driven wheel connected with a take-up shaft for a printing ribbon is controlled by a solenoid. CONSTITUTION:When no electric current is passed to the solenoid 16, a lever 11 is turned counterclockwise by being pulled by a spring 15, whereby the idler 13 is separated from a driving gear 6 so that a printing head 20 is not pulled by a spring 18, and the head 20 is separated from a platen 1, resulting in a non- printing condition. When an electric current is passed to the solenoid 16, a movable core 17 is moved toward the lever 11, which is rotated by the force of a spring 14, and the idler 13 is engaged with the driving gear 6. Therefore, when the carrier 2 is moved and the gear 6 is rotated, the take-up shaft 9 is rotated to feed the printing ribbon 23. At this time, a tension is generated in the spring 18 to pull the head 20, so that a printing part of the head 20 is pressed against the platen 1. Accordingly, the ribbon 23 is fed only in an actual printing condition.

Filed: 1989-03-15
Abstract: PURPOSE:To suppress deformation of a cylindrical face outward and inward by detecting number of revolutions of a drum, regulating a vacuum suction in response to the number of revolutions, and balancing a centrifugal force acting on the cylinder face with a negative pressure in a hollow chamber. CONSTITUTION:A vacuum pump 24 is operated while a drum 10 is at a halt, a hollow chamber 16 is evacuated to adsorb a sheet member 26 on the outer circumferential face of the drum 10. The setting pressure is set to a pressure of a degree not causing deformation to the cylindrical part 12. When the loading of the sheet member 26 is finished, the drum is accelerated up to a prescribed number of revolutions and a rotary encoder 30 detects number of revolutions and sends the detected value to a detector 42. Moreover, the detected value is fed to an arithmetic comparator 46, in which the centrifugal force acting on the drum 10 is calculated. On the other hand, a negative pressure signal in the cylinder, is inputted from the pressure sensor 34 to the arithmetic comparator 46 via a detector 44. When the centrifugal force is larger than the negative pressure, the comparator circuit 46 sends a comparison signal to an aperture controller 48. As a result, a throttle valve 40 is regulated to control the pressure in the hollow chamber 16 so that the negative pressure balances the centrifugal force.

Abstract: PURPOSE:To maintain present operation as it is without tripping even when a main circuit gets out of order by providing a turbine control device with a backup circuit which has the function of feedback control of rotational speed and keeping automatic balance with the main circuit. CONSTITUTION:The first controller 10 receives a rotational speed command signal S11 from a control device 11 of an upper stage and an actual rotational speed signal S34 and sends out a control signal S10. Variation 31 between output signals from the first and the second controllers 10, 20 is inputted to an integrator 21, while a variation S22 of its output signal S21 from an actual rotational speed signal S34 is inputted to the second controller 20. Normally, a selector 33 selects the S10 side, and a switch 32 is closed, then a signal S20 follows and coincides with S10. When the first controller 10 gets out of order, the switch 32 is opened and the selector 33 is changed over to the signal S20 side so that the rotational speed may be controlled to its value right before the controller is getting out of order.
