Title: Karman vortex flow meter
Inventor: NANUN MUTSUMI
IPC: G01F1/32
Filed: 1986-08-22
Abstract: PURPOSE:To stabilize the generation of a Karman vortex by providing an upstream columnar body whose section is nearly in an isosceles triangle shape and a downstream columnar body whose section is nearly in an isosceles trapezoid shape, and setting the angle of the isosceles sides of the downstream columnar body to about 60 deg.. CONSTITUTION:The section of the downstream body 21 is nearly in the isosceles triangle shape and the section of the downstream columnar body 22 is nearly in the isosceles trapezoid shape. The columnar bodies 21 and 22 are so arranged that the base parts 21A and 22A which have nearly equal lengths d1 and d2 are inserted vertically at a specific interval (a) in the flow direction of fluid and in parallel to each other. Here, the angle beta of the isosceles sides of the columnar body 22 is set to about 60 deg.. Consequently, when vortexes at the time of a low flow rate are visualized, pulsating flow follow-up performance which is highest in the shape of a generated vortex, specially, the mutual interference state between vortexes is obtained. Thus, a Karman vortex flow meter of simple constitution is obtained where Karman vortexes are generated stably against transient variation in the flow velocity of a pulsating flow.

Abstract: PURPOSE:To suppress the breakdown of an underlying substrate by converting the internal stress of a soft magnetic film formed on the substrate after a heat treatment thereof to a compressive stress and to improve the yield of head chips by selecting the coefft. of thermal expansion of the substrate at 155-170X10<-7>/deg. CONSTITUTION:The cause for the generation of the internal stress of the film after the heat treatment of the Fe-Al-Si system alloy film formed by an electron beam vapor deposition method occurs in the thermal stress and, therefore, there is a need for using the substrate, the elongation rate of which increases to the rate larger than the elongation rate of the film in such a manner that the elongation rate of the film and the elongation rate of the substrate at the time of cooling the same from the heat treatment temp. down to room temp. coincide with each other or the internal stress of the film acts as a compressive stress. The nonmagnetic substrate having 155-170X10<-7>/deg coefft. of thermal expansion at the heat treatment temp. of the substrate formed with the film is, thereupon, used as the substrate and the Fe-Al-Si system alloy film is formed thereon by the electron beam vapor deposition method. This alloy film is constituted of the compsn. ratio consisting of 3-6wt.% Al, 8-12wt.% Si and the balance Fe and has a high magnetic permeability and high saturation magnetic flux density.
