IPC: H04N19/126
Filed: 1993-01-14
Abstract: PURPOSE:To improve picture quality deterioration at an edge part such as a character periphery and to control the amount of data after compression to a specific value in field or frame units. CONSTITUTION:The edge part is decided from orthogonally transformed data and while a quantization weight distribution is switched, a 1st quantizing circuit 7 performs quantization on the basis of the quantization weight distribution to calculate a quantization coefficient (QM). This quantization coefficient (QM) is multiplied by the quantization weight distribution switched by the edge part decision making and a 2nd quantizing circuit 13 quantizes delayed orthogonally transformed data to generate a variable length encoding output. Thus, the quantization is performed with the quantization weight distribution matching the features of an input image, so recording and transmission of high picture quality are enabled. Further, the total amount of encoded data in one frame or one frame of the input image can be suppressed below a certain value.

Title: Control method of ignition and extinction of burner of multi-fuel combustion boiler
Inventor: ISHIDA SHIYOU
IPC: F23N5/00
Filed: 1984-01-18
Abstract: PURPOSE:To remove a disturbance factor in boiler-turbine cooperative control, by controlling a burner so that a quantity of variation of load is made to adjust by only one kind of fuel and ignition or extinction of a burner of the other kind of fuel does not occur while an ignition or extinction process of the burner of the one kind fuel is in progress. CONSTITUTION:Switches 11, 12 are excited respectively to illustrated positions if an instruction signal 1 is transmitted when a load of a generator is being made to vary by making multi-fuel combustion ratio of fuel A/B uniform. Similarly, signals 6, 3 to be generated by the instruction signal 1 excite also switches 66, 33 to illustrated positions respectively. A memory AM-3 stores a measured flow of the fuel A to be obtained directly before action of the switch 11 and a flow control valve of the fuel A performs fixed value control of the measured flow of the fuel A. Because of this, a variation of burner pressure for the fuel A disappears and ignition or extinction instructions of a burner for the fuel A is blocked. Simultaneously with the above matter, tracking of a measured multifuel combustion ratio is performed by a memory AM-1 through a multi-fuel combustion ratio fixing signal and a memory AM-2 stores a multi-fuel combustion ratio to be obtained directly before appearance of the signal 3. As the flow control valve of the fuel A is under the constant value control of the measured flow of the fuel A, a generation load, which is varying moment by moment, applies instruction of a flow variation to only a control valve of the fuel B. After the lapse of a fixed period of time, the instruction signal 1 becomes excitationless and the flow control valve of the fuel A reopens control based on the multi-fuel combustion ratio.
