Title: Device for watching thermal limiting value
Inventor: HAMADA JUN
IPC: G21C17/00
Filed: 1990-10-18
Abstract: PURPOSE:To avoid such unnecessary interruption that control rod-pulling out is prohibited although thermal allowance is actually enough by setting a conversion factor based on the simulation of the real atomic reactor starting time. CONSTITUTION:An arithmetic element 14 prepares the quantity equivalent to a thermal limiting value based on the LPRM signal (a) from a processing element 11 and the conversion factor (e) previously input in a data receiving element 13 and outputs as a signal (f). The fittest value or the value near it computed by the three dimentional simulator of offline based on a starting plan determined for example at the starting time of an atomic reactor is used for the setting of the conversion factor in this case. These conversion factors are renewed so that the reading of the LPRM may agree with this correct thermal limiting value at the time when the core performance computing is made and the correct thermal limiting value is computed by a process computer 6. Therefore, the unnecessary interruption times of the control rod pulling out operation can be reduced because an error from the correct thermal limiting value is little.

Title: Multirate sample rate resonance suppression system for magnetic disc
Inventor: HATTORI TOSHIAKI
IPC: H02P25/098
Filed: 1994-10-21
Abstract: PURPOSE: To suppress vibration through a digital notch filter by performing a notch filter operation for an output signal from a controller at a rate predetermined times as high as the sample frequency and outputting the result as an actuator control signal. CONSTITUTION: A magnetic disc takes in positional error signals 14 at a sample frequency (f) into a DSP1 through a magnetic head 7. Similarly, drive current signals 12 for an actuator 6 are taken in at same sample frequency (f) and a controller 2 having designed sample frequency of (f) generates a controller signal 10. A notch filter 3 suppressing mechanical resonance has a designed sample frequency of 2f and receives the control signal 10 being updated every other time. A control signal 11 for the actuator is outputted at a sample frequency of 2f from the DSP1. Since a resonance point of double frequency can be dealt with, effect of mechanical resonance having frequency equal to the Nyquist frequency of controller or above can be suppressed.
