Filed: 1979-01-26
Abstract: PURPOSE: To make it possible to make a multi-point forecast with high precision at a high speed through real-time processing without reference to the number of forecast reference points.  
     CONSTITUTION: A sampled input signal is inputted to subtracter circuit 11, where it is subtracted from a forecast signal. The output is inputted to quantization unit 12 and quantized according to fixed quantizing characteristics, and the output is led out as a coded signal through coder 13. The output of quantization unit 12, on the other hand, is added to the forecast signal by adder circuit 14. A forecast circuit which generates newly the above-mentioned forecast signal by receiving the above- mentioned addition signal consists of coefficient circuit part 15 which multiplies the above-mentioned addition signal by coefficients P 1 ∼P n , memory circuits D 1 ∼ D n  delays respectively signals after the coefficient process, and synthesizer circuit part 16 composed of an adder circuit adds the delay processing signal in sequence.

Patent JP-S61167824-A (JP)
Title: Photoelectric converting circuit
Inventor: AKITA SHIGEYUKI
IPC: H03K3/42
Filed: 1985-01-18
Abstract: PURPOSE:To prevent the oscillation frequency of a photodiode from varying greatly with ambient temperature by connecting the 2nd photodiode so that a current flows to the 1st photodiode in the same direction. CONSTITUTION:A dark current flows from the cathode of the 1st photodiode to its anode without reference to the illuminance of light and varies with ambient temperature. This dark current, therefore, flows to a capacitor 13 unless there is the 2nd photodiode 12 and charges the capacitor, so that the oscillation frequency varies. The 2nd photodiode 12, however, is connected to the capacitor 13 in parallel, so the majority of the dark current flows to a minus terminal 102 through it and the capacitor 13 is not charged. Therefore, the oscillation frequency of a signal outputted from an output terminal 103 has almost no influence of the ambient temperature and the photocurrent of the 1st diode 11, i.e. current proportional to the illuminance of light is obtained.
Patent JP-S63178747-A (JP)
Title: Manufacture of cast rotor
Inventor: YAMANISHI HARUO
IPC: H02K17/16
Filed: 1987-01-19
Abstract: PURPOSE:To manufacture a casting without cavity even on the side opposite to the gate side by dividing a cope in the vicinity of the axially central part of an end ring, causing an L-type first pipe and further second pipe to communicate with each other for ventilation and fitting a valve freely opening and closing a duct downstream from said first pipe. CONSTITUTION:If a second pipe 13 is ventilated as shown by the arrow from just before starting of casting, a pressure lowers in adjacent parts communicating with the valve 14 in the second pipe 13. Therefore, air in adjacent parts such as cooling fin forming grooves 4a, 4b flows into a first pipe 12 as shown by the arrow (a), passes through the second pipe 13 and is discharged outward. Further, by a push-out effect of cast conductor 15 and a suction effect in the second pipe 13, air is surely discharged outward and generation of cavity by involvement of gas is prevented. On the other hand, a molten metal conductor having entered the first pipe 12 is biased by closing of a duct in the second pipe 13 with the valve 14 after completion of casting. Therefore, a shrinkage at the time of solidification of an end ring 5 can be completely supplied by a molten metal conductor in the first duct 12. As a result, it is possible to prevent generation of cavity and shrinkage cavity in the end ring 5 on the side opposite to the gate side.

Title: Transmission system of half tone picture
Inventor: SHIMOTOONO SUSUMU
IPC: H04N1/41
Filed: 1984-01-20
Abstract: PURPOSE:To reduce the drop of compressibility without generation of blur by executing compressing encoding using the specific property of a half tone picture when the half tone picture is to be expressed by using a dither method. CONSTITUTION:A transmitted original is once represented by average value at the density level of a fine area unit, converted into addresses in accordance with a dither matrix and compressed and encoded successively to be transmitted. The transmitted data are decoded on the receiving side and picture element positions corresponding to the addresses on the transmission side, i.e. the relation of an address matrix 12, is referred from the decoded addresses. Thus, black picture element density conversion is executed by using the dither matrix indirectly to reproduce the half tone.

Title: Information system for plural types of maps
Inventor: INAGAKI SEIICHI
IPC: G06T11/60
Filed: 1990-01-18
Abstract: PURPOSE:To shorten the display switching time with a simple method by preparing a map type memory and controlling en bloc plural types of maps having different reduced scales and different hierarchies within a map system. CONSTITUTION:The hierarchy-based map information 6 and the common/ hierarchy-based attribute information 14 are stored in a computer 3. When the information 11 showing execution of a process of an electric power system is inputted from an input device 2, each hierarchy component of a power system chart 61 of the information 6 stores the attribute information on the power system chart included in the information 14 of each same hierarchy. When the switch is carried out among maps of different types via the device 2, the information 6 and 14 are stored for each hierarchy number and the same hierarchy numbers are not needed to be stored again owing to the correspondence secured between both information 6 and 14. As a result, the starting job of a map information system can be omitted even though the information 11 is inputted from the device 2 to process a river system chart 62. Then the display switching time is shortened.
