There is obtained a wire-rope flaw detector capable of realizing a high signal-to-noise ratio even in the case where only one detection coil is disposed. In the wire-rope flaw detector, there are provided a magnetizer that forms main magnetic flux in a predetermined section located along an axis direction of a wire rope (1) and a detection coil (8) that detects, in the predetermined section, leakage magnetic flux (13) emitted from a flaw portion (10) of the wire rope (1); a magnetic circuit member (7) made of a ferromagnetic material intervenes in a magnetic circuit for leakage magnetic flux that is interlinked with a detection coil (8); and in a space where at least one of the end portions, of the magnetic circuit member (7), that serve as the inflow port and the outflow port for the leakage magnetic flux is inserted between the detection coil (8) and a wire rope (1), an opening portion extends in such a way as to intervene between the foregoing end portion and the other end portion and is inserted between the detection coil (8) and the wire rope (1).

The present invention provides a metal-graphite composite material favorable to two-dimensional diffusion of heat and having a high thermal conductivity in two axial directions, and a production method therefor. The metal-graphite composite material of the present invention includes: 20 to 80% by volume of a scaly graphite powder; and a matrix selected from the group consisting of copper, aluminium and alloys thereof, wherein the scaly graphite powder in which a normal vector to a scaly surface thereof is tilted at 20° or higher with respect to a normal vector to a readily heat-conducting surface of the metal-graphite composite material is 15% or less relative to a whole amount of the scaly graphite powder, and the metal-graphite composite material has a relative density of 95% or higher.

A wire rope flaw detector comprises a back yoke and excitation permanent magnets, which form a main magnetic path in a predetermined section of a wire rope in the axial direction; a magnetic path member arranged in the predetermined section to be magnetically insulated from the back yoke and the permanent magnets and making the leakage flux generated from a damaged part of wire rope detour to the outside of the wire rope; and a detection coil wound around the magnetic path member for detecting leakage flux. The amount of leakage flux can be increased by providing the magnetic path member and since the windable area of the detection coil is increased, the number of turns of detection coil can be increased.

A release mechanism for use in a leveling apparatus that performs a leveling process on a work object that has been wound in a coil configuration as a result of the work object being passed between a front side work roll in contact with the front side surface of the work object and a back side work roll that is in contact with the back side surface of the work, wherein the releasing mechanism switches between a work clamp state that allows performance of the leveling process and a release state that releases the work object from the clamp state by displacing a work roll support member that supports one of the work rolls relative to the another support member to change a distance between the work rolls by utilizing rotational movement of an electric motor.
摘要:
There is provided a layer forming apparatus for forming a photosensitive layer of an electrophotographic photoreceptor, containing no bubbles in a coating liquid. In the layer forming apparatus for forming the photosensitive layer of the electrophotographic photoreceptor through the dip coating method, a lower end port of a dipping cylinder is distanced away in a horizontal direction from a coating liquid discharge port, and the coating liquid discharge port is disposed above the lower end port of the dipping cylinder, in order to prevent a bubble from moving into a coating liquid portion used for actual coating even when a bubble exits in the course of circulation of the coating liquid.
