    摘要： A heat transfer member has a heat transfer unit mounted on a mounting sheet. The heat transfer unit comprises a plurality of layers of wire mesh laminated and bonded together and to the mounting sheet. The spaces between the wires of the mesh layers of the heat transfer unit permit liquid to pass through the heat transfer unit so as to conduct heat. A semiconductor element (IC chip) is mounted on the mounting sheet, and to a base. The resulting assembly is immersed in a liquid. Preferably, the planes of the mesh layers are generally perpendicular to the mounting sheet and the semiconductor element and the material of the mounting sheet chosen to have a thermal expansion coefficient between that of the semiconductor element and the heat transfer unit to reduce thermal stresses. The wires of the mesh layers are preferably of copper as this is inexpensive and provides satisfactory heat conduction.

    摘要： A magnetic disk unit comprising a one-piece carriage structure having a small thermal off-tracking amount, with the carriage structure including a rotary shaft; guide arms integrally supported on a guide-arm retainer at their proximal ends and extending independently and parallely; bearing retainers formed on both ends of the guide-arm retainer; and bearings fixed on the bearing retainers rotatably connecting the guide-arm retainer to the rotary shaft. A center line in a direction of thickness of the outermost guide arm is located outside of that of the bearing in a direction of height thereof, and a concave portion is continuously formed on the bearing retainer. Thermal coefficients of expansion of the guide arms and the guide-arm retainer are substantially equal, with the carriage structure being fashioned of an alloy mainly containing Al and Si, eutectic crystal Si particles in the guide arm and/or the guide-arm retainer. The average value of the longest eutectic crystal Si particles therein is 1.6 .mu.m or less or the number of the eutectic crystal Si particles if 5.0 or more per 100 .mu.m.sup.2. In the carriage of manufacturing the carriage of the carriage structure is heated for five to fifteen hours at a temperature of 300.degree. to 500.degree. C. after die casting.
