Abstract
PURPOSE: To effect a seal gap adjusting in high accuracy by a system wherein a gap between an end surface of an outer circumference of a rotor and a surface of a sector plate is detected and operation of a sector plate driving motor is controlled by a time-width pulse in proportional to an amount deviated from a set value.
CONSTITUTION: A seal gap is measured by a non-contacting type sensor i utilizing a thermal deformation of a rotor as a disturbance, and a deviation signal between a signal (2) produced by the seal gap measurement and a set signal (a) from a gap setter a is set to an analog switch c through a proportion adjuster b, further, is sent to analog timers d1, d2 transducing an output 3 into a time function in accordance with an measurement objective portion determined by a synchronized signal (1). When the output (3) is possitive, the signal is sent to the timer d1 through a diode D1, while the signal is sent to the timer d2 through a diode D2 for a reversed direction when the output (3) is negative, thereafter, the signals are sent to blind sector setters e1, e2 respectively and are changed into pulse signals, which are changed into control signals for a sector plate driving motor g in switch circuit f1, f2, and drive an operating portion h.
