摘要： PURPOSE:To omit the necessity of many seismoscopes by using tree acceleration detecting means for detecting acceleration values in three directions perpendicular to each other, executing Fourier transformation of these output frequency levels to correct frequency characteristics, and when the sum of spectrum values exceeds a threshold, generating a scrum signal. CONSTITUTION:Signals outputted from the acceleration detectors can be corrected at real time by previously measuring correcting functions for correcting the frequency characteristics of respective detectors and storing them in a memory. Further, in regard to the change of sensitivity deterioration characteristic of acceleration detector, the correction function characteristic is corrected by a calibration test. On the basis of said knowledge, normal horizontal acceleration detectors 1a, 1b and a vertical acceleration detector 1c are arranged on the outside of an arithmetic part 2 and the arithmetic part 2 is provided with respective functions such as the rapid Fourier transformation for respective components, the correction of frequency characteristics of these detectors and the calculation of the sum of vectors. A calibrating signal is applied to execute Fourier transformation and a scrum signal is generated by using a comparator to which thresholds in respective frequency levels are applied.

摘要： Under the rated load amount of "Normal" and "Extra" drying degrees, a drying process carried out after the detections of the plurality of resistance values a passing time of at least one resistance value selected from among of the plurality of resistance values is predicted is carried out. The hot air operation time in accordance with the measured time is calculated, and the hot air operation during the calculated hot air operation time is carried out. When under the small load amount, a drying process is carried out in the form of a hot air operation by calculating a necessary time for "Damp" drying degree under a small load amount in accordance with a time for passing a predetermined resistance value after a lapse of a constant time from the start of drying operation. When one of "Semi", "Normal" and "Extra" drying degrees under the small load amount is selected, a hot air operation is carried out at a constant time according to the calculated time for "Damp" drying degree.

摘要： PURPOSE:To make the flow rate of a condensate constant and to secure the suction pressure and suction flow rate of a downstream-side pump by adding the filter tower by-pass valve to a condensate flow rate control system. CONSTITUTION:The condensate flow rate 12a and the number 13a of water sampling filter towers are inputted to a filter tower by-pass controller 13 and the difference between the condensate flow rate 12a and a flow rate 13b which is permissible for the filter towers is obtained as a by-pass valve flow rate signal 13c to control the filter tower by-pass valve 3. The valve 3 is closed when the signal 13c is minus or opened when plus. Consequently, the stable condensate flow rate is obtained.
