Title: Measuring tube for electromagnetic flowmeter
Inventor: KOMATSU SHINGO
IPC: G01F1/58
Filed: 1998-06-08
Abstract: PROBLEM TO BE SOLVED: To stabilize the zero point of a measuring tube and to improve the noise resistance of the tube by forming two flat surface sections which are faced to each other in parallel on the outer peripheral surface of the tube over the full length of the tube. SOLUTION: Flat surface sections 20 which are faced to each other in parallel with a pipe line 8 in between are respectively formed on the top and bottom outer peripheral surfaces of a measuring tube 1 over the full length of the tube 1 and exciting coils 2 are respectively fixed to the centers of the flat surface sections 20 perpendicularly to the axial lines of the tube 1 and electrodes 3 so that a magnetic field may be formed in the pipe line 8 in the direction perpendicular to the flowing direction of a fluid to be measured when the measuring tube 1 is conducted. Therefore, the coils 2 are not buried in the tube 1, but entirely exposed on the top and bottom surfaces of the tube 1.  Since thick portions are eliminated from the peripheries of the coils 2 and the occurrence of eddy currents around the coils 2 is prevented by using the flat surface sections 20 as the attaching sections of the coils 2, the influence of magnetic flux differentiating noise can be reduced.

Inventor: AZUMA MASAHIRO
IPC: C25D7/06
Filed: 1987-06-29
Abstract: PURPOSE: To permit uniform plating process of short-cut carbon fibers by selectively taking out the carbon fibers after completion of plating utilizing a difference in specific gravity and/or a magnetic means after the carbon fibers are plated by bring the short-cut carbon fibers into contact with a cathode as they are stirred in a plating bath. CONSTITUTION: Carbon fibers 8 are allowed to float up on the surface of a plating bath 1 by a circulation flow caused by an agitator 2 in the plating bath 1 and come into contact with a cathode 3 and energized, thereby the plating proceeds. At the advancement of the plating process to some extent, the fibers increase their own weight and their wetting properties and are sucked from the downward, then ascend again along the circulation flow, whereby the plating process is repeated in individual carbon fibers. In order to promote the separation of the plated fibers 8 from insufficiently plated carbon fibers 8, air 7 is blown from an air-blowing tube set to the lower part of the plating bath 1.  When the thickness of the plated layer reaches a prescribed value, the stirring and the electric current are stopped and the fibers 8 that sediment to the bottom are taken out by opening a valve 6, whereby the short-cut carbon fibers are uniformly plated.
