摘要: According to the method for preparation of ultrathin magnetic layer on semiconductor of this invention, a non-ferromagnetic metal buffer layer thinner than 40 ML is formed on the semiconductor substrate on which the magnetic layer is to be prepared. The thickness of the non-ferromagnetic metal buffer layer may be 0.5-9 ML, preferably 1-8 ML, most preferably 1.5-6 ML. Thereafter, the magnetic layer is formed on said non-ferromagnetic metal buffer layer. The thickness of the magnetic layer so prepared may be less than 40 ML, close to the limitation of ultrathin. Material for the non-ferromagnetic metal buffer layer is preferably a metal or metal alloy that is immiscible with the magnetic layer when the magnetic layer is formed on the buffer layer. In the embodiments of the present invention, the non-ferromagnetic metal is silver, while material of the magnetic layer is cobalt. This invention also discloses the magnetic structure so prepared.

摘要: The invention relates to heat transfer apparatus for cooling electronic components. There is a continuously increasing demand for compact electronic systems such as portable laptop computers and thirst for high processing power, leading to high heat generated by components residing within these systems. These electronic systems have to be cooled due to their fixed operating temperature ranges. Operating an electronic component beyond its rated operating temperature range will damage electronic components. Instead of conventionally utilising a bigger fan, a smaller sized solution is required for cooling an electronic component contained in a compact electronic system, for example a notebook computer. A heat transfer apparatus includes a heat carrier for conveying heat away from the electronic system into a radiator for dissipation. The radiator is placed into a cooler for directing air through the radiator and expelling heated air, cooling the radiator in the process.

摘要: An integrated cable-termination circuit is presented that can be selectably automatically configured to terminate a signal cable in conformance with one of a plurality of electrical interface standards, including, for example, CCITT/EIA standards V.11/RS-422 and V.35. Selected termination configurations are maintained when input voltages exceed power supply voltages or when power to the circuit is removed. A plurality of cable-termination circuits are provided to form an integrated selectable cable terminator for selectably terminating multiple cables, each in conformance with one of a plurality of electrical interface standards.
