Title: Recording medium for measuring nonlinear distortion
Inventor: HIRATA TAKAYOSHI
IPC: G11B3/00
Filed: 1979-05-15
Abstract: PURPOSE: To make it possible to measure easily the nonlinear characteristics of a reproducing device by only a simple measuring instrument by recording a composite pulse signal, which has different positive and negative crest values and includes no DC component, and a reference signal for a certain time with fixed amplitude and period.  
     CONSTITUTION: Reference pulse signal B of amplitude V 1  and composite pulse signal A are sequentially recorded as test signals on measuring recording medium 1 for a certain time and similarly signals are recorded up to n-th one. To the output terminal of reproducing device 2, nonlinear distortion measuring meter 3 is connected for measurement. When a reference pulse signal of the 1st amplitude appears at the output terminal of a preamplifier, meter 3 is given adequate amplitude by attenuator 31 and it is applied to BPF32 to measure the magnitude of a frequency component by voltmeter 33, thereby obtaining the 1st reference value. Then, the composite pulse is similarly measured to obtain the 1st distortion measured value. Then, the ratio of the distortion measured value of frequency 1/T to the reference value is unstable in case of a nonlinear system and a characteristic value is obtained corresponding to an input signal. This is repeated (n) times to obtain nonlinearity.

Title: Secam signal detection circuit
Inventor: TSUJI MASAKI
IPC: H04N7/01
Filed: 1990-03-08
Abstract: PURPOSE:To surely detect a SECAM signal by using an LPF to decrease the effect of a noise component in an FM demodulation output and giving the FM demodulation output with a level based on a frequency of a horizontal ident signal to a peak detection circuit. CONSTITUTION:An FM demodulation circuit 4 FM-demodulates a signal for a horizontal synchronizing signal period of an input TV signal. When the input TV signal is a SECAM signal, a horizontal ident signal is inputted to the demodulation circuit 4 and a level of an output of the demodulation circuit 4 changes with each horizontal period. A discrimination means 8 applies peak detection 5, 6 to the FM demodulation output given via a filter 10 to obtain a level difference of the peak detection outputs before and after one horizontal period so as to discriminate whether or not the inputted TV signal is the SECAM signal. Even when noise is invaded in the horizontal ident signal, the filter averages the FM demodulation component of the noise and a signal with a level based on a signal frequency for the horizontal synchronizing signal period is given to the discrimination means 8 and the SECAM signal is surely detected.

Abstract: PURPOSE:To secure the good matching characteristics over a wide band by forming the matching circuit between the SAW (elastic surface wave element) element and at least the high frequency circuit of the front step of the SAW element or the detecting circuit of the rear step. CONSTITUTION:The matching circuit is formed between SAW element 2 and at least high frequency amplifying circuit 1 of the front step of element 2 or the electronic circuit such as detecting circuit 3 or the like of the rear step. In other words, resistances 19-25 form detecting circuit 27D and coils 15 and 16 plus variable cap diode 18 form the matching circuit respectively. Then turning voltage VT is applied to diode 18. The local oscillation frequency becomes high in case voltage VT is high, and thus the capacity of the matching circuit is reduced. As a result, the BPF has the passing region at the high frequency band and has the passing range at the low frequency band in case voltage VT is low respectively. Accordingly, the matching band varies in accordance with the frequency band where the signal exists, thus securing the good matching characteristics over a wide band.

Filed: 1992-03-17
Abstract: PURPOSE:To maintain stable fluidized combustion and realize operation in a high plant load variation rate by discharging or bypassing air and air or gas of a gas system to other systems when a load of a pressurized fluidized bed plant is changed. CONSTITUTION:High pressure air 22 and coal are supplied to a pressurized fluidized bed boiler 14, where combustion gas 23 is produced to be supplied to a gas turbine 2, thus driving an air compressor 1 and a generator 3. In the case where a load is dropped, an extracted air flow rate control valve 41 is opened so that a part of the air 22 discharged from the air compressor 1 is bypassed to an exhaust portion of the gas turbine 2. Otherwise, a part of the air is blown to the atmosphere from a discharge side of the air compressor 1. Consequently, it is possible to control at least either one of a pressure inside the pressurized fluidized bed boiler 14 or a flow rate of the combustion air 22 so that the pressure and the flow rate can speedily follow a transient variation in flow rate and pressure of a gas system at the time of dropping of a load. As a result, stable combustion reaction can be maintained, and operation can be realized at high plant load efficiency.
