Title: Spread energy signal eliminating circuit
Inventor: MIYABE KAZUHIRO
IPC: H04N21/647
Filed: 1993-01-11
Abstract: PURPOSE:To eliminate an energy spread signal independently of whether or not a spread energy signal is superimposed on an input signal by adding an inverted triangle wave having a level of a half of an energy spread level. CONSTITUTION:A pulse generating circuit 3 generates a pulse phase-locked with an energy spread signal from which frame synchronization is detected and an integration circuit 4 converts the signal into an inverse triangle wave and inputs it to an adder signal level half reduction circuit 7. This signal is inputted to a clamp circuit 2, in which the signal is clamped to eliminate the remaining spread energy signal having a half level. Furthermore, when no spread energy signal is superimposed, the input signal is a signal subjected to spread energy in a reverse polarity by adding an inverted triangle wave to the input signal. Thus, the signal is eliminated by the clamp circuit.

Abstract: PURPOSE: To reduce the generation of cavitation through regulatin of the rotational frequency of an inducer by controlling an impeller, two shafts of an inducer and the connecting force of a variable speed coupling by way of a control circuit.  
     CONSTITUTION: It is assumed that the rotational frequency of an impeller 2 does not change, while an output signal Hs of a pressure gauge 11 lowers with a drop in the suction pressure of a pump. In this case, as an output signal Hso of a funtion generator 13 into which an output signal N of a tachometer 12 is left unchanged, an output signal (Hso-Hs) of an adder 14 turns to positive value and outputted to an excitation voltage generator 10. The generator 10 outputs an increment excitation voltage proportional thereto to an excitation coil 8 of an electromagnetic coupling which is excited by the sum of an electromagnetic voltage V and a voltage  ΔV. This strengthens the connecting force of the solenoid coupling 7 so much that  the suction pressure of the impeller 2 rises and the rotational frequency of the  inducer increases. Thus, the control of the revolution of the inducer 4 can reduce  the cavitation thereby improving the efficiency of the pump.
