摘要:
A ferromagnetic material can be formed in a very small size on the order of an atomic size and is capable of being stably magnetized. The ferromagnetic material comprises basic unit structures each consisting of a first atom (11), a second atom (12) of the same kind as the first atom (11), and a third atom (or atomic group) (13) of the same kind as the first atom (11) or of a kind different from that of the first atom (11). In each of the basic unit structures, the atoms are arranged on a surface of a substrate so that a chemical bond (14) is formed between the first atom or and the third atom or molecule, a chemical bond (14) is formed between the second atom and the third atom or molecule, a chemical bond or an electron path (15) not passing the third atom is formed between the first and the second atom.

摘要:
A ferromagnetic fine line has no loss of spontaneous magnetization even when fabricated ultra-small. The magnetization can be controlled by the proximity of the electrodes and the atomic level structure, and is protected from adsorption of impurities by embedding the ferromagnetic fine line in a nonmagnetic atomic layer.
摘要:
A fine wire is fabricated by supplying metal atoms to one row or a plurality of rows formed by extraction of terminated atoms or molecules to the surface of substance made non-conductive by terminating all dangling bonds on the surface thereof with atoms or molecules. The conductivity of the fine wire can be attained by supplying metal atoms larger in number to that required for just terminating dangling bonds formed by extraction of terminated atoms or molecules.

A fine wire is fabricated by supplying metal atoms to one row or a plurality of rows formed by extraction of terminated atoms or molecules at the surface of a substrate made non-conductive by terminating all dangling bonds on the surface thereof with atoms or molecules. The conductivity of the fine wire can be attained by supplying metal atoms larger in number to that required for just terminating dangling bonds formed by extraction of terminated atoms or molecules.
摘要:
To provide an electron exposure apparatus capable of providing high resolution and performing electron exposure at high speed, integrated tips are used. Only the tips provided at ends control distances between the tips and the surface of a wafer, and the tips used for electron exposure follow the wafer according to deformations of cantilevers, which occur due to the Coulomb force resultant from a voltage applied to each tip.
摘要:
A tool holder, for mounting a bit formed with a groove onto a power tool, includes a tool-holding tool, an engagement member, and a resilient member. The tool-holding tube defines a bit insertion hole that extends in an axial direction. The tool-holding tube is formed with an elongated hole that is in connection with the bit insertion hole and that extends in the axial direction. The engagement member is disposed in the elongated hole and partially protrudes into the bit insertion hole. The engagement member is movable, by abutment with and pressing force from the bit being inserted into the bit insertion hole, in the axial direction and, when located at a retraction position in the axial direction, also outward in a radial direction of the tool-holding tube. The resilient member is disposed to an outer periphery of the tool-holding tube at the retraction position. The resilient member increases in radial dimension from an initial state by pressure from the engagement member moving outward by pressing force from the bit. The resilient member resiliently returns to the initial state when pressure from the engagement member stops because the groove of the bit is located at the retraction position. As a result, the resilient member presses the engagement member inward in the radial direction into engagement with the groove of the bit.
