An outer pipe and an inner pipe are formed by drawing. Inner pipe is inserted into outer pipe and a metal core is inserted into inner pipe From this state, drawing is performed so that outer pipe presses tightly against inner pipe Metal core is pulled out, resulting in a two-layer clad pipe Alternatively, a two-layer clad pipe can also be made by drawing outer pipe and inner pipe without inserting metal core

Two-layer clad pipe

A split sleeve 1 for optical connectors is provided, which may be constructed from a single part with a reduced cost and which permits retention forces on larger and smaller ferrules to be easily adjusted in uniform manner. The split sleeve 1 includes a cylindrical member made from a metallic material, such as phosphor bronze or stainless steel, representing an appropriate spring-back action. A slit is extended in the axial direction from one end to the other end of the cylindrical member. One end portion 1a of the cylindrical member on one side of an intermediate portion is configured to have a larger diameter, while the other end portion 1b of the cylindrical member on the other side of the intermediate portion is configured to have a smaller diameter.

The invention is aimed at miniaturization and thinning of a magnetic head support device of a floating type. The magnetic head support device includes a load beam 3 having upstanding side rails 22 extending along the longitudinal side edges of the load beam. The magnetic support device also includes a gimbal 2 having upstanding side rails 21 extending along the longitudinal edges of the gimbal for a predetermined distance. The gimbal 2 is disposed below the load beam 3. The upper edges of the side rails 21 of the gimbal are engaged with the lower surface of the load beam 3, so that a predetermined spacing is maintained as between the lower surface of the load beam and the upper surface of the gimbal 2.

A decrease in the quality of parts constituting the magnetic head structure of a magnetic disk device is prevented and the degree of freedom of design for oscillation characteristics is increased. A magnetic head support structure 10 comprising an attaching base portion 12 for a magnetic head at one end and a gimbals spring 14 at the other end which are connected by a load beam 13 is integrally produced by rolling a linear steel material to form a ribbon of profile cross-section, which is then punched or pressed from the lateral surface thereof.
