摘要:
An aerial line tensioning device which uses an outer casing to protect the slide mechanism and the oscillation mechanism of the gas spring type aerial line tensioning device from disturbance, the slide mechanism comprising a cylinder case and a cylinder rod, and the oscillation mechanism being used to oscillate a connecting bar for connecting the cylinder and the aerial line. This construction improves operation reliability of the tensioning device and reduces maintenance service requirements.
摘要:
A laminate having excellent abrasion resistance to physical stimuli such as dust. The laminate comprises a base layer, a hard coat layer and a top coat layer containing flaky metal oxide fine particles all of which are formed in the mentioned order. The flaky metal oxide fine particles are hardened by at least one method selected from the group consisting of ionizing material exposure, ionizing radiation exposure, infrared exposure, microwave exposure and high-temperature vapor exposure.

Providing a track status monitoring device comprising an acceleration detection unit disposed on a railway car and detecting an acceleration at least in the axle direction among accelerations generated on a wheel of the railway car; a rail position detection unit disposed on the railway car and detecting a value indicating a position of the rail in relation to the wheel in the axle direction; an integration unit that calculates a value based on a 2 nd -order integrated value of the acceleration detected by the acceleration detection unit; and a subtraction unit that counterbalances an undulating component of the wheel by subtracting a value detected by the rail position detection unit from a value calculated by the integration unit, and calculates an amount of horizontal-direction displacement of the rail.

Disclosed is a truck lateral motion restricting device which can prevent a large impact from being applied to a stopper when the truck lateral motion restricting device is operated in the derailment. The device comprises a guard angle (52) which is provided along the inside of the rail (51) and a stopper (25) which projects downward from a more inward position than wheels (15) of the truck (11) and is in slidable contact with the inside surface (52a) of the guard angle, wherein the stopper comprises a slidable contact portion (28), which has a slidable contact surface slidable contact with the inside surface of the guard angle, and guide portions (31) which project at front and rear portions of the slidable contact portion and have a front end inclined in a direction separating from the inside surface of the guard angle and a base having a guide slope (31a) provided continuously to the slidable contact surface.
