Abstract:
An assembly for writing/reading high-density data on a recording media as a series of tags comprising a magnetic information bit pattern. The assembly includes an antenna positionable near the media; a source of electromagnetic radiation for producing an incident wave at least a portion of which can be coupled to the antenna; and, a means for coordinating a mutual positioning of the source of the electromagnetic radiation and the antenna, so that the antenna can generate a highly localized electromagnetic field in the vicinity of the media for inducing localized heating of the media. The assembly is capable of writing/erasing said high-density data by using an information signal for modulating the localized field generated in the vicinity of the media; the assembly is capable of reading by coordinating the mutual positioning of the antenna and the media.
Abstract:
An assembly suitable for reading data based on thermal coupling. The assembly can realize resolution/density specifications that can transcend diffraction limited focused laser beam techniques. The assembly includes a temperature sensor supported by a head-like structure, the temperature sensor capable of monitoring thermal coupling between the sensor and a media, and a heater element for heating the temperature sensor. A controller is used for coordinating a mutual positioning of the head-like structure and the media so that changes of thermal coupling between the assembly and a media provide indicia of a media bit pattern.
Abstract:
A thermal assembly comprising at once a reading-writing-erasing capability. The present invention, accordingly, can realize important advantages of providing dual yet independent capabilities or functionalities for manifesting reading-writing-erasing on the nanometer scale. An illustrative such thermal assembly includes a thermal heater for writing on a media; a temperature sensor capable of monitoring thermal coupling between the sensor and the media; and, a heater element for heating the temperature sensor.
Abstract:
An ultrafine tip for AFM and STM profilometry of trenches having sidewalls. The tip includes a lateral circumferential edge protrusion to allow profilometry of the sidewalls of a trench located in a semiconductor or insulator substrate.
Abstract:
Two dimensional profiling of samples, such as integrated circuits containing trenches or lines, is accomplished using contact force atomic force microscopy by controlling the tip position responsive to the real-time measured local slope of the surface in contact with the tip.
Abstract:
A readily oxidizable metal such as lithium formed along a cathode is collected in an electrolytic tank within a collecting chamber, the level of electrolyte is caused to rise to a predetermined top level at which the lithium leaves the collecting chamber and overflows into a transfer compartment, the level of electrolyte is lowered to a predetermined bottom level at which the poured-off lithium leaves the transfer compartment and passes to the discharge compartment, the level of electrolyte is raised to the top level in order to ensure overflow into a discharge tube. A stream of inert gas is passed into the discharge compartment and the lithium is transferred to a chamber for treatment in an inert atmosphere and conversion to ingots in the pure state.
Abstract:
A cooling device for cooling a computer includes: a flexible and conformal fluid heat-exchanger coupled to a surface of the computer; a liquid coolant material circulated through the fluid heat-exchanger to convey heat from the fluid to an external cooling apparatus; an enclosure defined when the fluid heat-exchanger is placed against the computer surface; and a vacuum applied to the enclosure, removably sealing the fluid heat-exchanger to the computer to provide a vapor seal for the enclosure.
