    摘要： A vertical shaft type pump including a bearing device in which water in the pump is utilized as lubricating water without supplying water to the bearing from the outside of the pump, thereby repeatedly conducting no-load operation in the air (in such a state that water is not pumped) stably for a long period of time. In the pump, a water storage tank upwardly opened is fixed to a rotary shaft, and the lubricating water (the water in the pump) is retained within the water storage tank so that the bearing is operated while being always soaked in the lubricating water. Also, foreign substances in the water storage tank are mixed with the water without deposition, and the water containing the foreign substances is replaced by the newly pumped water.

    摘要： The process for forming an ultrafine-particle film according to this invention is characterized by irradiating the surface of a target of a raw material with laser energy in a predetermined atmosphere under conditions where a plume is generated, exposing a substrate (a base material) directly to the plume generated, and thereby forming a film. The substrate is positioned in the plume at a distance, from the surface of the target of the raw material, of at least the mean free path of atoms and/or molecules of the raw material (or components thereof). By so positioning the substrate, ultrafine particles of the raw material are deposited on the substrate. The plume containing a large amount of ultrafine particles moves at a high speed; and exposure of the substrate, at the specified position relative to the target, to the plume causes strong adhesion of ultrafine particles contained in the plume to the substrate, resulting in formation of a film.

    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.

    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 covered acceleration sensor element includes a weight portion, a support frame portion surrounding the weight portion, a plurality of flexible beam portions for connecting the weight portion to the support frame portion to support the weight portion, piezoresistance elements provided on the beam portions, and wirings for connecting them. An upper cover and a lower cover enclosing the periphery of the weight portion together with the support frame portion are joined to the face and back of the support frame portion. Acceleration in the directions of three axes, i.e., a first axis in the joining thickness direction, a second axis in a plane perpendicular to the first axis, and a third axis in the plane and perpendicular to the second axis, or acceleration in the direction of any of the axes, is detected from changes in the resistances of the piezoresistance elements. The support frame portion is separated by separation grooves into an inner frame and an outer frame. The upper cover and the lower cover are joined to the outer frame. The inner frame is connected to the outer frame by a plurality of inner frame support portions having flexibility. The beam portions are connected to both sides of the weight portion along the second axis and the third axis. The inner frame support portions are connected to both sides of the inner frame in a direction in which they are rotated nearly 45 degrees from the second axis and the third axis.
