Title: Production of needle crystal fe-zn alloy magnetic particle powder
Inventor: HORIISHI NANAO
IPC: C09D5/23
Filed: 1979-07-30
Abstract: PURPOSE: To produce magnetic powder of needle crystal Fe-Zn alloy of superior magnetic characteristics by oxidizing an aqueous mixed soln. of Fe(OH) 2  and Zn(OH) 2  by O 2  gas to allow Zn-contg. needle crystal goethite particles to form and subjecting the same to calcine and reduction treatment after filtering.  
     CONSTITUTION: An aqueous finely and uniformly mixed soln. of Fe(OH) 2  and Zn(OH) 2  of 0.1W2.3atom% of Zn(OH) 2  with respect to Fe in Zn equiv. and ≥11 in pH is oxidized by an O 2 -contg. gas to allow Zn-contg. needle crystal goethite particles to form. After these are separated by filtering and are rinsed followed by drying, they are dehydrated under heating and are further calcined by being heated in an atmosphere comprising heating steam and nonreducing gas of 30W100% in steam partial pressure to 350W700°C. Since this yields the needle crystal hematite particles of 0.1W2.0μm mean long axial length and 10W30m 2 /g specific surface area by a BET method, these are reduced at 350W600°C in a reducing gas, whereby the Fe-Zn alloy magnetic particle powder of superior saturated magnetic flux density and coercive force is produced.

Abstract: PURPOSE:To judge whether a moving speed or direction determined through the use of GPS satellites is correct or not, by obtaining the distances up to three satellites based on the times required by respective satellites for reaching a receiving point. CONSTITUTION:A frequency synthesizer 104 delivers a signal of appropriate frequency corresponding to that of a radio wave to be received and a frequency converter 102 receives a target signal GS1 being converted into an intermediate frequency. A carrier tracking circuit 11 monitors the signal SG1 and tracks the carrier of received signal constantly. The difference (Doppler frequency) between a detected carrier frequency and the carrier frequency of a radio wave radiated from a GPS satellite is then delivered as signal SG2 to a spectrum reverse diffusion circuit 12 and a microcomputer 15. Since the position of each satellite constituting the GPS is known along with the accurate signal delivery time thereof, the distance between a satellite and a receiving point can be determined by measuring the time required by the signal delivered from each satellite for reaching the receiving point.

Title: Data processing in chromatography
Inventor: NAKATSUKA KIYOHARU
IPC: G01N30/62
Filed: 1984-05-15
Abstract: PURPOSE:To automatically perform analysis with high accuracy, in the comparison of a plurality of chromatograms, by determining the holding times of one or plural main peaks in each chromatogram and performing data processing so as to coincide with the holding time of each chromatogram with each of said determined holding times. CONSTITUTION:When a plurality of chromatograms are compared to investigate correspondence, one or plural main peaks are determined in each chromatogram. Next, the holding time of each chromatogram is converted so that the holding times of these main peaks are substantially coincided between chromatograms to each other. This conversion is performed by multiplying the holding time by coefficient, by adding or subtracting constant with respect to the holding time, a primary linear regression equation, a min./max. method or spline function. Because the peak coming to the reference of holding time conversion may be determined from expericenc even if the condition of the gradient or flow amount of a migration phase is changed, the analysis of each peak can be performed automatically in almost all cases by a computer.

IPC: B21B37/66
Filed: 1980-07-19
Abstract: PURPOSE:To eliminate the high-frequency-wavelike change of plate thickness and improve plate thickness accuracy and yield by separating the change components of rolling load to every factor and controlling the same respectively separately. CONSTITUTION:At the time of performing rolling through one or more rolling mills having coiling and uncoiling reels, the change components of rolling loads are separated to a load change DELTAPt occurring in a tension change, a load change DELTAP1 occurring in a change of the plate thickness and deformation resistance on inlet side and a load change DELTAPe occurring in roll eccentricity, respectively. The electric currents of reel motors or mill motors positioned before and behind rolling mills are controlled by the change component of the former one, whilist the plate thickness control by roll gaps having been used heretofore and the load compensation control of rolling mill motors are accomplished by the latter two, whereby the high-frequency-wavelike change in the plate thickness owing to the mutual interferences of plate tension in a rolling mill system consisting of rolling mills and reels is eiminated simultaneously with the change in the thickness on the outlet side owing to various factors.
