Filed: 1978-12-25
Abstract: PURPOSE:To decrease the necessary multiplication number and the input addition number by  giving previously the 2-point discrete Fourier conversion to the two input signals against a complex conjugate symmetric matrix element and then giving the real or imaginary number multiplication to the obtained real or imaginary number and furthermore with the 2-point discrete Fourier  conversion given to the output. CONSTITUTION:The 2-point descrete Fourier conversion is given previously to a pair of inputs  f1, f6, f2, f5 plus f3 and f4 which are multiplied by the complex conjugate multiplication term and through 2-point DFT circuits 11-13. Then the real numbers of real number terms Xn-X3n of  the multiplication terms are multiplied addition terms of to the output of adder circuit 14 in  circuits 11-13 each through multipliers 16-18, and imaginary number parts jYn-jYan of  multiplication terms are multiplied through imaginary number multipliers 21-23 to the subtration term which received the subtraction via subtractor 15. Futhermore, the output of multipliers 16-18 are added together through adders 24 and 25, and input f0 is added via adder 26. This  addition result is applied to DFT circuit 29 in the form of the 1st terms, and the outputs of  multipliers 21-23 are added through adders 27 and 28. Thus the addition result of the 2nd term  is obtained to be applied to circuit 29, and the 2-point discrete Fourier conversion is carried  out through circuit 29.

Abstract: PURPOSE:To perform the effective cooling without increasing the engine load by discharging/absorbing the hydrogen gas between metallic hydrides in the first and second heat exchangers by means of the engine waste heat and outside air in a system utilizing the reaction heat of metallic hydrides. CONSTITUTION:The engine waste heat is fed into the first heat exchangers 10a, 10a' from a path 6 through which the engine cooling water is circulating, then the hydrogen gas is discharged from the first metallic hydride M1H in the first heat exchangers 10a, 10a' and is absorbed by the second metallic hydride M2H in the second heat exchangers 10b, 10b'. The second metallic hydride M2H builds-up heat due to this absorption, but is cooled by the outside air fed into a cooling path 8. On the other hand, when the M1H completes to discharge the hydrogen gas, it is cooled by the outside air, absorbing the hydrogen gas discharged from the M2H, then the M2H cools down by itself after discharging the hydrogen gas, thereby the car cooling output is fed through a cold heat take out path 9.

Filed: 1989-06-26
Abstract: PURPOSE:To improve the detection sensitivity of an analysis by reducing the size of the shape of the wick for the optical train used when the analysis is taken by thin layer chromatography (TLC). CONSTITUTION:The wick 1 is arranged in the optical train 2 and the area of the tip part where the wick 1 abuts on a sample cup 3 is set smaller than the area of any other end part.
