Filed: 1983-07-29
Abstract: PURPOSE:To prevent the occurrence of variations in product quality and any influence attributable to a secular change or the like, by conducting detection by detectors at both driving and driven sides of an actuator, while detecting the actual injection timing of fuel on the basis of phase difference calculated by a time lag being compensated by a reference value. CONSTITUTION:During engine driving at an engine speed n1 and a rack position R1, if injection timing is theta deg., a sine wave in frequency proportionate to the engine speed N1 is converted into a pulse train and inputted into an A terminal of a microcomputer 34 from a detector 2 at the driving side while another pulse train obtained out of a detector 3 at the driven side is inputted into a B terminal of the said computer. And, a value T1 of a free run timer is read out by the pulse to be inputted into the A terminal and stored in an An address, and when a pulse is inputted from the B terminal as delayed at time t, a value T2 of the free run timer is stored in a B address, then a value T3 to be inputted into the A terminal again is stored in an An+1 address. Next, the N1 is found on the basis of these T1 and T3 values, reading out the data R1 from a circuit 38, and desired injection timing t'1 is calculated whereby the t1 is calculated from a difference between T1 and T2, and t''1 is calculated from a time lag in a cam of theta+0, making it the actual injection data and, after calculating error time t upon comparison between these t'' and t', spark delay or advance timing control takes place.

Abstract: PURPOSE: To reduce pressure loss of exhaust gas flow in a condensate steam turbine, by providing inner casing supporting ribs, guide plates for dividing exhaust ports and guide plates for deflecting the exhaust gas flow in the lower-half portion of the low-pressure exhaust casing.  
     CONSTITUTION: In the lower-half portion 1 of outer casing, there are provided inner casing supporting ribs 7, 8 forming steam passages. A first guide plate 10 is connected at its upper end to rib 8 and divides at its lower end exhaust ports 10 into two halves. An inclined bottom plate 11 is provided at the bottom of said lower-half portion 1 of outer casing. A second curved guide plate 13 is provided between center rib 6 and upright rib 12 for deflecting axial flow of exhaust gas in perpendicular direction. Flux A of exhaust gas is passed through a space formed by ribs 8, side plates 4 and the first guide plates 10, whereas flux B of exhaust gas is passed through a space formed by ribs 8, upright ribs 12 and the first guide plates 10. Then, they are discharged to the outside from exhaust ports 5. Since the exhaust gas flow is thus divided into fluxes A and B in the manner that any interference is not caused between them, pressure loss of the exhaust gas flow can be lowered.

Filed: 1986-06-18
Abstract: PURPOSE:To improve the reliability of the paper separating function by elastically restricting the relative movement between a separating roller supporting shaft and a clutch roller supporting shaft along the guide groove of a connecting guide which engages with the both supporting shafts. CONSTITUTION:The guide groove 14a of a connecting guide 14 is formed in the direction of the axis centers of the both supporting shafts of a separating roller supporting shaft 10 and a clutch roller supporting shaft 11. A spring 15 elastically suppresses the relative movement of the both supporting shafts 10 and 11 in the direction of the guide groove. Therefore, the contact line between a separating roller 8 and a clutch roller 9 is held onto the axis center inner surfaces of the both supporting shafts 10 and 11, and the contact line between the separating roller 8 and the clutch roller 9 is held parallel to the both supporting shafts of the separating roller supporting shaft 10 and the clutch roller supporting shaft 11 by the balance in the right and left, and the stable revolution connection between the separating roller 8 and the clutch roller 9 can be obtained. This connection is not influenced by the inclination angle in the paper feed direction, since the connection is not due to gravity, and an automatic plain paper feeding mechanism can be obtain. Therefore, the reliability of the paper separating function can be improved.
