Abstract: In an optical fiber cable in which an optical fiber ribbon formed by parallelly arranging a plurality of optical fibers is packaged in an internal space, a core portion of each optical fiber is made of pure quartz and an effective cross-sectional area of the core portion at a wavelength of 1,550 nm is 110 ?m2 or more and 150 ?m2 or less. The optical fiber ribbon is an optical fiber ribbon in which the optical fibers are connected by continuously applying an adhesive resin between adjacent optical fibers. An occupation ratio of the optical fiber ribbon to the internal space calculated from a ratio of a cross-sectional area of the internal space to a cross-sectional area of the packaged optical fiber ribbon is 25% or more and 55% or less.

Abstract: A capacitance type electromagnetic flowmeter whose output is relatively free from fluctuations caused by external vibrations has a flow tube supported in a casing member by means of members having elasticity and viscosity (e.g., O-rings). Magnetic parts such as coils and a core are fixed to the casing member so as to define a space therewith, and protective rings are kept liquid-tight with respect to the flow tube by O-rings interposed therebetween. The equivalent mass of the flowmeter section vibrating integrally with the flow tube is reduced to increase the resonance frequency. Further, since the flow tube is insulated from vibrations of the protective rings, the flow is less subject to vibrations, thereby decreasing fluctuations in output due to external vibrations.

Abstract: An electromagnetic flow meter for industries includes a transducer and a signal processor provided separately from the transducer. The transducer having an exciting circuit, an amplifying and calculating part and a transmitting part outputs an analog flow rate signal and digital signals which are superimposed to the an analog flow rate signal to the signal processor. The analog signal sent to the signal processor is passed through the signal processor without receiving any signal processing and the digital signals are sent into the transducer or taken into the signal processor through alternating current coupling means. The data transmission is diagnosed by checking the conformity between the data stored in the signal sending part and the received data. Data set in a data setting part provided in the signal processor are sent to the transducer through a transmitting cable in which the flow rate data are also transmitted.

The case has a length longer than that of the ceramic measuring pipe and flanges at both ends thereof. Inner diameters of the flanges are slightly larger than an outer diameter of the ceramic measuring pipe.

Abstract: An electromagnetic flowmeter comprises a ceramic measuring tube through which fluid to be measured flows, a pair of electromagnetic coils disposed on the outer surface of the measuring tube in the central region thereof at diametrically opposite positions and generating a magnetic field in a direction perpendicular to the direction of flow of the fluid, a pair of measuring electrodes fixed to the outer surface of the measuring tube in the central region thereof at diametrically opposite positions and having electrode axes perpendicular to both the direction of flow of the fluid and the direction of the magnetic field, and a pair of metallic shields fixed to the outer surface of the measuring tube in surrounding relation to the measuring electrodes. A pair of the measuring electrodes and a pair of the metallic shields are fixed to the ceramic measuring tube by a reaction product due to an interface reaction with the ceramic measuring tube under heating.

Abstract: An electromagnetic flowmeter for measuring the flow rate of a fluid. The flowmeter has a measuring tube made of ceramics and defining a fluid passage therein for the fluid, electrodes having ends exposed to an interior of the measuring tube through holes which are formed in a wall of the measuring tube, a magnetic field generating device disposed around the electrodes, and a case encasing the measuring tube, the electrodes and the magnetic field generating means. A ratio t/R between a wall thickness t and a mean radius R of the measuring tube is determined such that stress generated in the measuring tube by the fluid in the measuring tube does not exceed the rupture stress of the measuring tube. The measuring tube can have flanges on both axial ends thereof, a radial height of the flange from an outer surface of the measuring tube is not greater than the wall thickness of the tube when the tube is made of Al.sub.2 O.sub.
