Abstract: There is provided a method for producing a rope member, provided with a rope of a bundle of synthetic fibers and a clamping member fixed to the rope and forming a portion with which the rope is to be connected or fastened to an external member, wherein a filler having permeability to the rope and containing a liquid and particles of an inorganic material dispersed in the liquid is made to permeate into a part of the rope, and the clamping member is fixed to the rope by installing the clamping member to cover the part of the rope permeated with the filler and by tightening the clamping member. The liquid is evaporated and only the inorganic material particles remain between the fibers of the rope. The clamping member is prevented from slippage even when a high load is applied to the synthetic fiber rope having high tensile force.

Abstract: Projections and recesses or the like are formed or an adhesive is coated on slide contact surfaces of a main cartridge body rotatably accommodating a disk such as a magnetic disk or an optical disk and a shutter mounted movably on the main cartridge body for opening or closing an opening formed in the main cartridge body for exposing a portion of the disk to outside to provide the slide contact surfaces with low friction to prevent wear of the shutter and/or the main cartridge body.

Abstract: A disk cartridge with a write protect mechanism includes a cassette casing in which a disk is rotatably housed. The cassette casing includes upper and lower halves. The upper half includes a planar wall and a standing peripheral wall, and the lower half also includes a corresponding planar wall and a corresponding standing peripheral wall. The cassette casing is formed by facing the standing peripheral walls and firmly securing them to each other. A housing space is provided in the cassette casing for slidably receiving a manually operable switching member of the write protect mechanism therein. An inlet is provided at the standing peripheral walls of the upper and lower halves for communicating the housing space with an outside of the cassette casing therethrough. The manually operable switching member is inserted into the housing space through the inlet provided at the standing peripheral walls.
