Abstract: In a superconducting magnetic thrust bearing with integrated dynamotor, a first fixed core is formed to have a U-shaped cross-section in a direction of the central axis of the cylindrical shape with an opening of the U-shape being directed perpendicularly to the central axis, and a superconducting coil is arranged on the inside of the U-shaped portion of the first fixed core formed into the U-shape. A rotary core has projecting ends at positions opposite to two projecting ends of the U-shape of the first fixed core, and a magnetic flux guide path, at a position opposite to an armature core, with a shape varying at predetermined intervals in the winding direction of the superconducting coil. The rotary core is constituted such that it rotates relatively to the first fixed core and is able to move in the direction of the central axis of the first fixed core.

Abstract: Disclosed is a positive-type photosensitive composition which can form a metal compound film pattern at high resolution and with less affection by organic residues. The positive-type photosensitive composition comprises: a metal complex component (A) which can form a metal compound film when applied and subsequently fired; and a photosensitizing agent (B). In the composition, a ligand in the component (A) is preferably a multidentate ligand having an aromatic compound as its skeleton. According to this construction, even a composition containing substantially no photosensitive resin can impart photosensitivity and a metal compound film pattern can be formed readily.

Abstract: A wheel guard apparatus capable of preventing a wheel from derailing and preventing a vehicle from seriously deviating from a track even if the wheel has derailed includes a fixed portion fixed to a railroad tie located between main line rails; a movable portion supported by a rotating shaft provided on the fixed portion and extending in a horizontal direction and configured to be rotatable around the rotating shaft toward a track center side; and a guard rail located at a position separated from the rotating shaft of the movable portion and held to extend in parallel with the main line rail. The guard rail includes an outer stopper portion configured to prevent the wheel from derailing toward an inner side of the main line rail and an inner stopper portion configured to prevent a derailed vehicle from deviating to an outer side of a track.

Abstract: A derailment prevention guard includes a guard member (3) installed within a gauge and a support member (6) fixed to a sleeper (4) or a concrete slab track. The guard member (3) engages a hold member (8) moveable around an axis (7) supported by the support member (6) as turning center between a main rail (1) and the inside of the gauge on the sleeper. The support member (6) engages the hold member (8) by bolt (12) through turning the hold member (8) toward the main rail (1) around the central axis (7) as turning center on the sleeper (4), and the guard member (3) can be shunted inward by turning the hold member (8) toward the inside of the gauge around the central axis (7) as turning center on the sleeper (4) after loosening the bolt (12).

Abstract: An object of the present invention is to realize a structure able to well retain contact performance between an overhead line and a slider 7b, across the entire lengthwise direction of the slider 7b. The slider 7b formed of slider elements 34a and 34b divided in the crosswise direction of a vehicle, is supported on the upper surface of a slider support body 9. A center support member 12 forming the slider support body 9 is elastically deformed downward in a concaved shape across the longitudinal direction, due to a load applied due to contact between the overhead lines and the slider 7b. Also, together with this, both ends of the center support member 12 are supported on a shoe body 3a so as to allow free oscillation via the respective end section support members 13.

Abstract: A wheel speed detection system including a rotator, a sensor head, a detector, a pulse converter, a speed calculator and a threshold shifter. Plural concave and convex portions are formed on a periphery of the rotator rotating together with a wheel. The sensor head includes a coil to generate an alternate current magnetic field. The detector excites the coil to generate an eddy current on the concave and convex portions, and outputs alternate current detection signals corresponding to changes in the eddy current generated with rotation of the rotator. The pulse converter converts the alternate current detection signals into pulse signals according to preset threshold levels. The speed calculator calculates rotational speed of the wheel based on the pulse signals. The threshold shifter shifts the threshold levels corresponding to a difference between a default average and an average of the alternate current detection signals actually outputted from the detector.
