PROBLEM TO BE SOLVED: To provide a heat conductive intermediate structure suitable for utilization when radiating heat from one or a plurality of components mounted to memory modules or other devices.SOLUTION: A heat transfer intermediate material is arranged on or along one surface of a flexible heat conductive sheet, or the flexible heat conductive sheet is jointed to a first layer and a second layer of the heat transfer intermediate material enclosed therein, or interposed therebetween. The flexible heat conductive sheet may be a flexible porous graphite sheet. The heat transfer intermediate material may be a heat conductive polymer. Polymer-polymer bonding easily occurs by forming holes in the graphite sheet. The polymer-polymer bonding can promote the mechanical joint of the first layer and the second layer to the graphite sheet and promote the provision of heat conduction between the first layer and the second layer.

PROBLEM TO BE SOLVED: To provide a shield suitable for shielding electronic parts on a printed circuit board from electromagnetic interference (EMI)/radio frequency interference (RFI). SOLUTION: A shield 100 comprises a shield housing having a sidewall 102 and an integrated upper face 130. The side wall 102 comprises an upper wall part 132 and a lower wall part 108, wherein the wall parts 132 and 108 together demarcate an interlock 104. The upper wall part 132 extends downward from the integrated upper face 130. By means of the interlock 104, the integrated upper face 130 and the upper wall part 132 are attached to the lower wall part 108 in a removable manner. When the interlock 104 is canceled, the integrated upper face 130 and the upper wall part 132 are completely separated from the lower wall part 108. The integrated upper face 130 and the upper wall part 132 can also be attached again to the lower wall part 108 by means of the engagement of the interlock 104. COPYRIGHT: (C)2009,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide a conductive metal coating on a porous filler material. SOLUTION: A method for producing a metal-coated filler includes the steps of: obtaining a supporting mixture by mixing a solution of an organic diol with a plurality of porous filler particles; forming a reaction mixture by bringing a metal-salt solution into contact with the supporting mixture; and heating the reaction mixture to a temperature within the temperature range of 50-200°C. Metal cations in the metal-salt solution are reduced to metal particles by the organic diol and arranged on the porous filler particles and pore surfaces of the filler particles. Then, the metal-coated filler may be isolated. Electrically conductive and/or thermally conductive articles including the metal-coated filler and methods for producing the same are also disclosed.
