Title: Process control device
Inventor: ONO KAZUTERU
IPC: F01D19/00
Filed: 1990-11-30
Abstract: PURPOSE:To prevent hunting of a process system and breakage of an apparatus by providing a lower limit restricting means by which the lower limit value of a process signal detected by a process amount detecting means is restricted to a prescribed value so as to give it to a calculating means. CONSTITUTION:The rotational speed of a turbine 1 is detected by a rotational speed detector 4, and the rotational speed signal thereof is inputted step to a lower limit restrictor 8. When the rotational speed signal detected by the rotational speed detector 4 exceeds the restricted value of the lower limit restrictor 8, output of the rotational speed detector 4 is inputted into a calculating circuit 6 from the lower limit restrictor 8. Hence, a flow amount regulation value 3 is operated according to the deviation signal between a rotational speed demand signal and the rotational speed signal which are found out by the calculating circuit 6 in a value opening control circuit 7, and the amount of steam or gas which are supplied into a turbine 1 is controlled until the rotational speed signal of the burbine 1 matches the rotational speed demand signal finally. It is thus possible to prevent hunting of a process system and breakage of an apparatus.

The strength of the inclined magnetic field per unit electric current generated at the center by each of both inclined magnetic fields 21 and 23 differs largely from each other and, as the result, the inclined magnetic field substantially generated as a difference of both cases and the electric current-magnetic field inversion efficiency becomes high. As only the main inclined magnetic field coil 21 is moved, the supporting structure can be made to be light-weight. As the amt. of correction for the vortex electric current, as it is proportional to the strength and the ratio of change with time of the magnetic field generated by the main inclined magnetic field 21, the centers of both inclined magnetic fields can be made to coincide with each other and the effect of the correction can be made smooth in the inspecting space. As the result, high image quality is obtd. in ultrahigh speed photographing.
