Title: Analog-to-digital converter
Inventor: TAKEMOTO TOYOKI
IPC: H03M1/20
Filed: 1980-01-19
Abstract: PURPOSE:To make it possible to reduce considerably the number of comparator corresponding to the resistor group to be used to obtain similar accuracy as conventional one has, by inputting a stair step signal into the 1st reference power source terminal and inputting another stair step signal into the 2nd reference power source terminal. CONSTITUTION:Terminal A, circuit B and signal line C represent the analog input signal impressed terminal, sample hold circuit, and signal line to which sample held analog input signal is transmitted, respectively. This signal is input into comparator group F and then becomes one side signal of the differential type comparator, respectively. Moreover, terminals D1 and D2 are the power source terminals to be used for comparison, and each of them is connected both ends of resistor group E, respectively. A stair step signal of 0.5-2V is input into terminal D1 and a similar signal of 0.1-1.5V having a constant difference of 0.5V against the former signal is input into terminal D2. By this, to obtain a similar accuracy as conventional one has, the number of comparator corresponding to the resistor group can be reduced considerably.

Title: Abrasion resistant centrifugally cast casting of cast iron and its production
Inventor: AOKI MASAMI
IPC: B22D27/20
Filed: 1981-01-14
Abstract: PURPOSE:To obtain a cast iron casting of which the outside surface layer has superior abrasion resistance in centrifugal casting by separating by gravity the carbide powder having a specific gravity larger than that of the iron added to molten metal for casting and high hardness and abrasion resistance from said iron. CONSTITUTION:Powder to be added to molten metal for casting is carbide or double carbide, for example, WC powder. This is extremely vulnerable to reaction with the O2 in the atmospheric air and decomposition. Thereupon, as a measure for prevention of its oxidation, carbide is added to the molten metal in the state wherein it is settled in molten flux. The molten flux is preferably the one of the b.p. higher than the temp. of the molten metal (that is, of a low m.p., a high b.p., and low viscosity) at which carbide powder can be added at low temp., and it settles immediately in the bottom of the molten flux and is thereby prevented from oxidizing, and when it is teemed into the molten metal, it does not evaporate and foam. The molten metal mixed with this carbide is subjected to centrifugal casting, and the addition of the carbide is preferably just prior to casting. In this case, the cast iron casting formed with the carbide layer in one piece on the outside surface is obtained.

Title: Liquefaction of coal
Inventor: SUNAMI YOSHIHIKO
IPC: C10G1/00
Filed: 1980-01-18
Abstract: PURPOSE: To raise liquefaction efficiency of coal without investing much money in equipment, by classifying powdered raw material coal into specific particle sizes, followed by feeding coal with smaller particle size and higher active mass than that of coal before the classification to liquefaction process.  
     CONSTITUTION: Powdered raw material coal is proviously classified into coal with particle diameter not more than 15mm, and coal having active mass higher than that of coal before the classification is fed to liquefaction process. Namely, this is based on the fact that a blended coal with high active quality content has relatively better crushability and is readily granulated into fine particles and one with high inactive quality content has poor crushability.  
     USE: Useful for preparing artificial crude oil and binders.

Title: High frequency power amplifier for two bands and moving object communication terminal machine with that
Inventor: FUJIHASHI YOSHIKUNI
IPC: H03F3/60
Filed: 1998-01-14
Abstract: PROBLEM TO BE SOLVED: To stabilize a system and to make it highly efficient with simple circuit constitution by using a 1/4 wavelength line in the stabilization circuit of a high frequency power amplifier for two bands. SOLUTION: The signal wave of a first frequency band is inputted from an input terminal 201 and it is amplified. The signal wave of a second frequency band is inputted to an input terminal 202 and is amplified. Then, it is outputted from output terminals 203 and 204. At that time, the synthesized resistance value of first and second resistors 101 and 111 decides the stability of the high frequency power amplifier for two bands. A connection point 113 is grounded by a capacitor 103 in terms of high frequency. The 1/4 wavelength line 112 inverts the impedance of the second frequency band. The impedance of a connection point 114 is approximated to open and the resistance value of the first resistor 101 decides stability.  On the other hand, the 1/4 wavelength line 112 does not invert the impedance of the first frequency band and therefore the impedance of the connection point 114 is not approximated to open. Then, the synthesized resistance value of the first and third resistors 101 and 111 decides stability.

Filed: 1987-01-14
Abstract: PURPOSE:To respond with equal priority to plural interruption requests, by providing a shift pulse generation circuit, and setting the leading of plural outputting pulses as the sampling timings of corresponding interruption inputs. CONSTITUTION:The leading of the pulses p1, p2, p3, and p4 outputted from the shift pulse generation circuit 1 are set as the sampling timings of the corresponding interruption inputs. And when interruption input signals i1 and i3 are inputted, and first leading transition occurs in the p3, an OR circuit 6 asserts a common interruption signal (i) by asserting the output of a q3 by an FF4, then, all of the shift pulses are invalidated. Next, an interruption processing on the interruption i3 is performed, and when it is completed, all of the shift pulses are validated again. And next, the interruption processing is performed on the interruption i1 with a similar procedure. In this case, it is likely that the i1 is processed first based on the phase state of the shift pulse, therefore, it is possible to set the priority of the interruption i1, i2, i3, and i4 on equal terms.

Abstract: PURPOSE:To enable a high speed scanning of beam by employing an arithmetic circuit for executing an MEM algorithm as a frequency analysis means. CONSTITUTION:An arithmetic circuit is used as a frequency analyzer 12 to implement MEM as a well-accepted power spectrum computation algorism. The frequency resolution function DELTAf of the frequency analyzer 12 is given by a half amplitude level of the spectrum which is obtained as a result of using a sine wave signal of a duration time DELTAt as an input signal 14. As illustrated, the frequency resolution f of the MEM is by far higher than that of the Fourier conversion and additionally by the MEM, a frequency resolution function is obtained  regardless of the duration time DELTAt of the input signal. Therefore, the use of an MEM computing circuit for the frequency analyzer 12 enables the resolving of a Doppler frequency accordinging to a plurality of moving targets regardless of a short time of irradiating the moving target 2 with an antenna beam from a radar 1, ensuring a high speed scanning of the antenna beam from the radar 1.
