摘要： PURPOSE:To produce a lightweight high damping material excellent in workability as well as in vibration damping property by applying galvanizing to the surface of Al or Al alloy, subjecting the resulting galvanizing layer to homogenizing treatment at specific temp. and then to cooling, and forming a Zn-Al alloy layer of specific thickness. CONSTITUTION:The surface of Al or Al alloy is galvanized. As to the above galvanizing, it is preferable to form a plating layer of >= about 5mum thickness by means of electroplating or hot dipping. Subsequently, homogenizing treatment is applied to the above galvanizing layer at 275-420 deg.C, preferably about 300-400 deg.C, followed by cooling. As the above cooling, rapid cooling by means of water cooling, etc., is preferred. By the above treatment, a Zn-Al alloy layer having a thickness of >=10mum thickness, preferably >= about 20mum, and consisting of a fine eutectoid structure of Zn and Al is formed on the surface layer. By this method, the lightweight Al-base high damping material excellent in workability and having superior vibration damping property can be obtained.

摘要： PURPOSE:To dissipate heat generated from a semiconductor element, and to wholly eliminate noise without resonance with the vibration of the element by forming a pectinated fin of an extruded material of Mg or Mg alloy. CONSTITUTION:A pectinated fin is formed of an extruded material of Mg or Mg alloy, and particularly it is desired to use Mg alloy which contain 0.1-10wt.% of Si, the balance of Mg and unavoidable impurities. If the Si adding amount is less than 0.1wt.%, it is similar to the case of pure Mg, while if it exceeds 10wt.%, its extrusion is deteriorated, and many cracks occur on the surface. The most desirable addition range of the Si is 0.3-3wt.%. Thus, heats generated from a transistor 3, a power IC or a transformer attached to a base plate 2 are dissipated from an extrusion fin type heat sink 1, vibration generated from the transistor 3, the power IC or the transformer is transmitted to the heat sink 1 to be rapidly attenuated by the fin so that the fin itself is not vibrated.

摘要： PURPOSE:To obtain a better surface and enable cooling using a hollow substance for an extruded shape by having an integrally formed screw feeder for feeding bulk material torsionally extruded and manufactured by a spirally-formed extruding die with a bearing. CONSTITUTION:Torsionally extrusion is performed using a spirally-formed extruding die with a longer bearing than that of an usual extruding die. At this time, a hollow substance is used for an extruded shape. The cross section of the vane 2 of a screw feeder is formed in asymmetry with the cross section perpendicular to the axis 1 of the screw feeder. In this way, a long feeder with the better surface is obtained and the temperature rise of bulk material is prevented by hollow makeup to pass cooling medium through the hollow portion.
