Title: Clock intermittent demodulation circuit and intermittent reception demodulation device
Inventor: OGA TETSUAKI
IPC: H04B7/26
Filed: 1994-04-14
Abstract: PURPOSE:To provide an intermittent demodulation circuit which can quickly start the phase control and can shorten the ON time of a receiver by providing a circuit which stops in a power OFF state after holding the frequency and the phase of a symbol clock and a circuit which always oscillates. CONSTITUTION:A reference clock 36 is always oscillated, and the power supplies of other circuits are intermittently turned on and off to wait for reception of the clocks 36. In a power ON state, a reception circuit 32 and a detection identifying circuit 34 demodulate the received signals and send the timing detection signals contained in the demodulation data to a BTR circuit 35 as the clock control signals. A U/P counter 47 operates by the output of a phase detector 46 to change the dividion ratio of a variable division circuit 48 and to set the phsse difference at zero between a symbol clock fS and the signal 39. When the power supply is turned off, the output of the counter 47 is set at zero and the division ratio is set at 1/n. The clock fS keeps its phase that is set right before the signal 39 is cut. In a power ON state, the phase is detected in a state set right before the power supply is turned off. Thus the phase control is quickly started.

Title: Method of estimating life of centrifugal pump
Inventor: YAMAMOTO YOICHI
IPC: F04D1/00
Filed: 1995-03-31
Abstract: PURPOSE: To estimate the life accurately by performing the life estimation, based on the change to the time passage of the increased inner leakage of a centrifugal pump, in the case of performing the estimation of life by the discharge pressure: discharge flow rate characteristic of the centrifugal pump. CONSTITUTION: When the pump has become unable to discharge required flow Qx at the time of working pressure at use place being Px, it is judged that the pump has come to the end of its life. The (discharge pressure P)-(discharge flow Q) characteristic of the centrifugal pump can be approximated by the expression of P=PC-α.Q<2> . But, PC is shutoff pressure (P at the time of Q=0), and α is pressure drop coefficient. Since the shutoff pressure PC(t) of the pump can be operated from the expression using the increased quantity of inner leakage within the pump, pressure drop coefficient, etc., the quantity of inner leakage at a certain time t can be inferred by measuring this shutoff pressure PC (t). The life estimation is performed, based on the change to time passage of the amount of increase of the quantity of this inner leakage.
