Title: Production of flux cored wire for welding
Inventor: SAEKI NOBUROU
IPC: B23K35/40
Filed: 1982-09-27
Abstract: PURPOSE:To improve the packing condition of a welding flux and the welding condition with a stable arc by supplying and packing the flux by vibration into a welded steel pipe which is a wound body and wire drawing the pipe to a prescribed diameter. CONSTITUTION:A belt-like steel sheet is formed to a cylindrical shape, and while both side edges are pressed with squeeze rolls, the edges are joined by high frequency induction welding, thereby forming a welded steel pipe 2. The weld beads on the inside and outside surfaces of the pipe are cut away by an external bead cutter and an internal bead cutter. The welded steel pipe is heated in a heating furnace and is then reduced to a smaller diameter with a rolling mill; further the pipe is reduced to a smaller diameter by cold rolling and is taken up and coiled on a steel bobbin. The bobbin is placed on a vibration table and is a powdery flux 3 is packed by vibration in the steel pipe. Since there are no weld beads, the flux is packed extremely smoothly and quickly. The pipe is then drawn and is subjected externally to copper plating thereafter the pipe is reduced to the final wire diameter.

Title: Circuit element tester
Inventor: WAKAMATSU HIDEKI
IPC: G01R27/28
Filed: 1988-07-05
Abstract: PURPOSE:To enable execution of stable and precise measurement over a wide band by a method wherein lines used for connecting a element under test are ended with the respective characteristic impedances on the occasion when four- terminal-pair measurement is conducted. CONSTITUTION:Resistances R1 to R4 connected to terminals on the tester side of central conductors of lines CL1 to CL4 are selected to be equal to the respective characteristic impedances of the lines. Then a transfer function (output/ input) and an input impedance of each line is V2=V1/(coshgammal+sinhgammal)=V1e<-gammal> and Z1=Z0, where the characteristic impedance of the line CL is denoted by Z0, a line length by l, a propagation constant by gamma, a voltage between terminals l1 and g1 by V1, a voltage between terminals l2 and g2 by V2 and the input impedance by Z1. When a loss of the line CL is small accordingly, the voltage V2 turns to be identical with phase-shifted V1, and the amplitude thereof is maintained to be identical with that of the latter. Since besides, a phase shift alone is varied with a frequency in the circuit, the stability of a negative feedback loop is maintained by conducting phase compensation of a narrow band amplification/phase compensation amplifier NBA.
