  • Publication number: 20070103874
    Abstract: A heat dissipating device for a memory chip comprises a heat dissipating body; a middle section of each of two opposite sides of the heat dissipating body having a hook; a distal end of each hook being bent as a hooking end; wherein the hook can be hooked to the via holes by the hooking ends to buckle the via holes so as to fix a memory chip to the circuit board. Each of the four corner of the heat dissipating body is extended with a protrusion which is bent from the heat dissipating body to have the same orientation as the hook. The heat dissipating body has a recess at a center portion thereof. An outer side of the bending section is chamfered as a guiding angle. The hooking end may be a flat sheet, a cambered sheet or a U shape sheets.

  • Publication number: 20070092517
    Abstract: The present invention provides novel methods of reducing memapsin 2 ?-secretase activity in a subject, decreasing levels of ?-amyloid peptide in the brain of a subject, treating Alzheimer's disease and/or reducing the size and/or number of ?-amyloid plaques in the brain of a subject. The methods may include the step of administering an effective amount of truncated memapsin 2 protein, anti-truncated memapsin 2 antibody, and/or nucleic acid encoding a truncated memapsin 2 protein or anti-truncated memapsin 2 antibody. The present invention also provides related pharmaceutical compositions and uses thereof.

  • Publication number: 20060203454
    Abstract: A heat sink for memory strips comprises two heat transfer plates respectively attached on two sides of a memory strip. The upper edges of the heat transfer plates are further provided with retaining tongues and retaining rings. The extended portion of the combined heat transfer plated above the memory strip forms a heat radiating section which further includes a multitude of radiating fins for enhancing the cooling effect.

  • Publication number: 20060061975
    Abstract: A protecting device of a memory module comprises two protecting sheets capable of covering a memory. Each upper edge of the protecting sheet has a buckling sheet and a buckling seat. One buckling sheet of one protecting sheet is capable of being buckled to the buckling seat of another protecting sheet. A front edge of each buckling seat is lowered so as to form an upper section surface and a lower section surface. The buckling hole has a lower buckling hole in the lower section surface and an upper buckling hole at the upper section surface. A front edge of the buckling sheet is lowered so as to form an upper section surface and a lower section surface. The lower section surface of the buckling sheet is formed with a buckling piece; and the buckling piece is extended with at least one tenon.
