摘要： An apparatus in which a magnetic field is generated by an excitation coil provided in the outside of a conduit and electromotive force generated in electrodes attached on the conduit is detected to thereby measure a flow rate of a fluid flowing in the conduit, in which the conduit is made thinner in a manner so that a ratio of the axial length of the conduit to the inside diameter of the conduit is set to a value within a range of from 0.2 to 1.0, and in which correction data previously analyzed in accordance with magnetic permeability and inside surface conductivity of a mate piping to which the conduit is to be connected are stored so that a detection signal from the electrodes is corrected on the basis of the correction data to thereby measure the flow rate of the fluid flowing in the conduit.

摘要： Winding structure for static electrical induction apparatus such as transformers, reactors, or the like. A winding assembly is disposed in a space formed between a pair of inner and outer insulation continuous walls which are disposed in a container so as to commonly include the vertical axis of the container thereby defining the space therebetween. An inner vertical coolant passage is formed between the winding assembly and the inner insulation wall and an outer vertical coolant passage is also formed between the winding assembly and the inner insulation wall. The winding assembly is composed of a plurality of coil units stacked on one another in the vertical direction with separation at predetermined intervals so as to form horizontal coolant passages between vertically adjacent ones of the coil units, the inner and outer vertical coolant passages communicating with each other through the horizontal coolant passages.A plurality of coolant flow control members are disposed in discrete relation from one another in at least selected one of the inner and outer vertical coolant passages in a manner so that a horizontal sectional area of the selected vertical coolant passage is decreased periodically at a pitch of nP along the vertical direction where n represents an integer which is not smaller than two (2) and P represents a pitch of the coil units along the vertical direction.Further, each of the coil units may be divided into at least two, inner and outer, coil sub-units disposed concentrically with each other in a common horizontal plane to thereby additionally form an intermediate vertical coolant passage between the vertically stacked inner coil sub-units and the vertically stacked outer coil sub-units. The coolant flow control members are disposed only in this intermediate vertical coolant passage to decrease periodically the horizontal sectional area thereof at the pitch of nP in the same manner as mentioned above.

摘要： A current collecting apparatus provided with sliders 2 for collecting electric power from a power feeder 1, a current collector 3 for collecting power, an insulator for insulating and supporting the current collector 3, and a flexible conductor for delivering the power collected by the current collector 3 to a conductor 5, which is connected to the flexible conductor and used for supplying the power to the vehicle side. The conductor 5 and the insulator 4 are disposed so that the former is offset with respect to the latter in the crosswise direction of a railway vehicle. With this arrangement, aerodynamic noise emanating from the current collector loaded on the vehicle running at high speed can be substantially reduced.

The winding units are divided into a plurality of winding sub-units to define a central vertical cooling path therebetween, which central vertical cooling path includes a via flow path and a branch inducing flow path, whereby cooling fluid flows in opposite directions and at substantially the same speed in the horizontal cooling paths along upper and lower surfaces of each of the winding units having the branch inducing flow path. In this manner, the entire winding is uniformly cooled.
