Filed: 1988-03-14
Abstract: PURPOSE:To measure a mass flow rate of a fluid linearly, by a method wherein a difference between electric resistors wound round on a conduit is adjusted to be proportional precisely to the mass flow rate of the fluid flowing through the conduit. CONSTITUTION:A differential amplifier 20 outputs a potential difference between a potential at the node of a resistance 1 and a resistance 2 and a potential at the node of two resistors A and B. An output E of the differential amplifier 20 is expressed as E=c[(RA-RB)i/2]=c(DELTARi/2) [(c) is an amplification constant] and is proportional to a difference AR in electric resistance between the two resistors A and B. Thus, the output E of the differential amplifier 20 is proportional to the difference DELTAR, and by adjusting a variable resistance Rk of a proportional multiplication circuit 21, an output E+(kE)<2> of a multiplier 22 can be made proportional to flow rate Q. By adjusting the variable resistance Rk beforehand, therefore, the mass flow rate Q of a fluid F flowing through a conduit T can be measured linearly with excellent precision.

Title: Superconducting coil
Inventor: UEDA KAZUO
IPC: H01F6/06
Filed: 1990-03-12
Abstract: PURPOSE:To prevent quenching which can be generated much in the coil center by making two end coils and the center coil independently wound around bobbins. CONSTITUTION:This coil comprises a center coil 11 and end coils 12, 13, which are wound respectively around independent center coil 21 and end coils 22, 23. Therefore, a large axial electromagnetic force occurs in the end coils 12, 13; but the axial electromagnetic force occurring in the center coil 11 is small. Winding the end coils 12,13 separately from the center coil does not allow the axial electromagnetic force occurring in the end coils 12, 13 to cover the center coil 11, and a large compression force is not applied on the center coil 11. This process hardly generates slips of superconductor in the axial center of the center coil 11 where quenching most easily occurs.
