Abstract: The present disclosure relates to a MoS2-Ni electrode and, in more detail, to a method for manufacturing an alkaline electrolysis electrode through co-sputtering, improves a 1T structure yield through a single process, and provides an electrolysis electrode with high activity in alkaline water electrolysis.

Abstract: A voice coil motor is disclosed which comprises a yoke member composed of a central portion forming magnetic path, left/right fringes and upper/lower fringes, a moving coil wound movably around the central portion of the yoke member, and permanent magnets being adhered on the upper/lower fringes of the yoke member and applying magnetic field to the moving coil, wherein the yoke member is formed by overlapping at least two members of different permeabilities so as to uniform each reluctance of lines of magnetic force being generated from the permanent magnets and flowing through the yoke member.

Abstract: A voice coil motor is disclosed which conveys a head of optical or magneto-optical disk drive or magnetic disk drive as a kind of a linear motor. The motor comprises a yoke member composed of a central portion, upper/lower fringes and left/right fringes forming magnetic paths, permanent magnets being adhered on the upper/lower fringes of the yoke member and each having an air gap with respect to the central portion. A moving coil is wound slidably around the central portion of the yoke member, and a shorted turn offsets the magnetic flux due to the current flowing in the moving coil, wherein the shorted turn has a plurality of fins on its conductive sleeve-shaped body and is disposed primarily in the yoke member except the section where the moving coil moves. The motor demonstrates an excellent control function while generating a maximum amount of thrust.
