    • Disclosed is a pneumatic tire, in which turbulent flow-creating ridges extending from the inner circumference side to the outer circumference side are formed at intervals in the tire circumference direction on the tire surface of a tire side part, wherein: said turbulent flow-creating ridges have edge parts, as viewed in the sectional shape cut in the radial direction; the front wall angle, which is made between the front wall faces of the turbulent flow creating ridges to be hit by an air flow and the tire surface, ranges from 70o to 110o; and, as a side-reinforcing rubber constituting said tire side part, a rubber composition prepared by blending 100 parts by mass of a rubber component containing 10 mass % or more of a modified conjugated diene polymer, which is obtained by conducting a modification reaction between a terminus of a conjugated diene polymer and an alkoxysilane compound having a primary amino group or a precursor capable of forming a primary amino group through hydrolysis to thereby introduce the primary amino group or the precursor capable of forming a primary amino group through hydrolysis to said terminus, and further adding a fusion accelerator to the modification reaction system in the course of the modification reaction or after the completion thereof, with 10 to 100 parts by mass of carbon black having a nitrogen adsorption specific surface area of 20 to 90 m2/g. Thus, it is possible to provide a durability-improvable tire, in which the temperature inside the tire side part can be lowered due to efficient heat radiation, and the durability during run-flat traveling and the rolling resistance during normal traveling, as the rubber composition, can be simultaneously improved.

    • A vortex flow meter includes a measuring tube in which a fluid is carried, a vortex generator provided in the measuring tube for developing a Karman vortex in the fluid, a magnetic field generator generating a magnetic field across the measuring tube downstream of the vortex generator, a pair of electromotive force measuring electrodes provided downstream of the vortex generator for measuring an electromotive force generated by the Karman vortex passing across the magnetic field, a pair of reference electrodes provided at locations upstream and downstream of the electromotive force measuring electrodes, respectively, for measuring a potential at each location, and a detector circuit electrically connected to the electromotive force measuring electrodes and the reference electrodes for calculating the flow of the fluid from the electromotive force and the potential measured by the reference electrodes. The flow is calculated by subtracting the potential difference of the reference potential measuring electrodes from the electromotive force measured by the electromotive force measuring electrodes. This allows the flow meter to have an increased measuring range, meet a wide range of flow conditions, have a simple construction, and have measurement accuracy.
