Abstract: PURPOSE:To cancel the residual magnetic flux of the stator and to enable to avoid the effect due to residual magnetism, by making longer the normal drive pulse width immediately after the corrective of the step motor than that immediately before the corrective drive, in electronic watch of corrective drive system. CONSTITUTION:High frequency signal being time reference is produced from the oscillation circuit 16, frequency dividing circuit 17 sequentially divides this to form one second signal and other circuit operating signal, the control circuit 18 synthesizes various drive pulses and controls the drive-detection circuit 19 suitably, and the drive pulse is fed from the circuit 19 to the motor 20.

Filed: 1982-04-05
Abstract: PURPOSE:To stably control the level of a condensate head tank by a method wherein the change of system flow rate is detected and controlled before said change of system flow rate shows itself in the change of the condensate heat tank level. CONSTITUTION:The level of a condensate heat tank can be controlled to keep constant by controlling outflowing flow rate by means of the controlling of a condensate head tank level control valve 7 based upon an output signal issued by a PID controlling device 15, to which the mismatching between a level setting signal set by a setter 12 and a present level signal issued by a condensate head tank level detector 1 and the mismatching between an inlet inflowing flow rate signal issued by a flow detector 13 arranged at the inlet of the condensate head tank and a flow detector 14 arranged at the outlet of the condensate head tank are inputted. Furthermore, when the system flow rate in a condensate purification system is little, one-element-control by means of the condensate head tank level signal only is possible so as to avert the influence of detection error, which may occur in case of a little flow rate.

Title: Back-up protective relay device for generator
Inventor: SATO OSAMU
IPC: H02J3/38
Filed: 1993-03-16
Abstract: PURPOSE:To make it possible to set a distance relay coordinated with a protective equipment on the power transmission line side by changing the value of an input voltage of the distance relay by using a resistor depending on the operating conditions of other generators. CONSTITUTION:If a plurality of generators T, 8 and 9 are connected to a power transmission bus 3, a current 12 decreases so that an impedance 2 seen from the distance relay 10 becomes larger than the line impedance up to the actual short-circuit point. At this time, among the inputs of short-circuit back-up protection distance relay 10, the voltage of the distance relay 10 is reduced by resistors 25 to 27 having respectively different resistance values switched by auxiliary contacts 19 to 20 of the generators 7, 8 and 9 in an input circuit of voltage (PT secondary voltage) as generator information, by which the value of generator voltage V seen from the distance relay is virtually made smaller in response to the change in T1, and the result V/11 is made constant. In this way, by making constant the impedance seen from the distance relay 10, the protection range can be made constant regardless of the number of operating units of generators.
