Title: Automatic gain control circuit
Inventor: AIISO ATSUSHI
IPC: H03G3/30
Filed: 1987-03-06
Abstract: PURPOSE:To prevent a signal with a small amplitude just after the input of a signal with a large amplitude from being suppressed exceedingly by providing a circuit detecting the amplitude of the input signal and making the AGC effective when the amplitude of the signal input is a prescribed value or over and stopping the AGC function when the amplitude is a prescribed value or below thereby fixing the gain with respect to the input signal to a prescribed value. CONSTITUTION:Gain variable circuits 2, 3, 5 have an automatic gain control (AGC) function keeping the amplitude of an output signal constant, but stop the function forcibly at the input of a small amplitude signal to activate gain fixed circuits 6-8. Since the gain to the input signal in this case is fixed to a prescribed value (e.g., maximum value), even when the negative feedback control signal keeps a value to decrease the gain just after a large amplitude signal is inputted, it is forcibly cancelled and the small amplitude signal is amplified at a gain of the prescribed value and appears at an output terminal. Since the gain fixed circuits 6-8 are not activated at the input of a large amplitude signal, the negative feedback control by the gain variable circuits 2, 3, 5 is applied in this case.

Title: Condenser
Inventor: SODA MASAHIRO
IPC: F28B1/02
Filed: 1983-03-30
Abstract: PURPOSE:To provide a condenser in which the deaerating capacity can be fully used by installing dummy pipes that are not fed with the cooling water in the lowermost part of cooling pipes disposed in a barrel of the condenser. CONSTITUTION:A condenser used for a turbine power generating plant has a square tube-like or cylindrical container whose barrel 1 is opened in the upper part for a steam inlet duct 2 and is opened in the lower part for a condensate outlet pipe 3 that is connected to a suction pipe of a condensate pump. By installing dummy pipes 14 in the lowermost part of cooling pipes contained in the barrel, the rising flow of steam (s) enters from under the dummy pipes 14 and rises from the lowermost part of the cooling pipes 9 toward an air drawing pipe 12. As the dummy pipes 14 are not fed with the cooling water, the pipe temperature of the dummy pipes is maintained at the steam temperature, i.e. the saturated temperature under the pressure in the condenser. Therefore, since the condensate drain dropping from the lowermost part of the cooling pipes 9 to the dummy pipes 14 is heated almost to the steam temperature while dropping through the dummy pipes 14, an adequate deaeration can be done, resulting in an improvement in the deaerating performance.
