Title: Electronic device
Inventor: HEIKE SEIJI
IPC: H01L21/822
Filed: 1996-10-14
Abstract: PROBLEM TO BE SOLVED: To realize an extremely fine patterning exceeding a limit drastically by fabricating an electronic device using a surface level being formed in a band gap through a dangling bond or the like. SOLUTION: A conductive layer on the surface of a semiconductor substrate 1 is stripped by means of a scanning tunnel microscope while leaving only the parts corresponding to a quantum dot 2, a gate electrode 3, a source electrode 4 and a drain electrode 5 thus fabricating a single electronic transistor. The gap between the source electrode 4 and the quantum dot 2 and the gap between the drain electrode 5 and the quantum dot 2 are on the order of 1nm which allows tunneling of electrons. The number of electrons to be tunneled at one time depends on the voltage being applied between the source electrode 4 and the drain electrode 5. Current flowing between the source electrode 4 and the drain electrode 5 is controlled or switched by applying a voltage between the gate electrode 3 and the quantum dot 2 thereby varying the energy level in the quantum dot 2.

Title: Scanning electron microscope
Inventor: TAMURA NOBUAKI
IPC: G01R31/302
Filed: 1997-10-03
Abstract: PROBLEM TO BE SOLVED: To realize a scanning electron microscope by which an insulating part and a conductive part on the surface of a sample can be observed clearly distinctively. SOLUTION: A voltage changing periodically is applied from an oscillator 11 to a substrate of a sample 5. In case that the surface of the sample 5 is composed of an insulator, the strength of secondary electrons generated from the insulator is hardly changed, when the voltage changing periodically is applied to the substrate 12 of the sample 5. On the other hand, in case that the surface of the sample 5 is conductive, generation of the secondary electrons from the surface of the sample 5 is suppressed, and the signal amount of the secondary electrons is decreased during the period when the electric potential of the surface of the sample 5 is kept positive. Conversely, during the period when the electric potential of the surface of the sample 5 is kept negative, generation of the secondary electrons is increased, and the signal amount is also increased.  As a result, when the voltage applied to the sample 5 is modulated by being synchronized with horizontal scanning signals and also is synchronized as the same voltage having the same phase is applied to each positions of the sample 5, the change of the brightness of an image appears as vertical stripes on the part of the conductive material of the surface of the sample 5.

Title: Acceleration detector
Inventor: SAITO HIDETOSHI
IPC: G01P15/12
Filed: 1987-10-26
Abstract: PURPOSE:To detect acceleration as variation in electric resistance value by providing a pendulum type movable part which moves according to the acceleration and varying the intensity of a magnetic field operating on the magneto- resistance element of a detection part by the pendulum movable part corresponding to the acceleration. CONSTITUTION:The weight 3 of the pendulum movable part slants at a constant angle to its moving direction and a peripheral surface part 3a extends slantingly to the moving direction X. Therefore, when the peripheral surface part 3a in a state shown by a solid line moves in the moving direction X and enters a state shown by an imaginary line, it leaves the magneto-resistance element 6b and comes close to the magneto-resistance element 6a. When the peripheral surface made of a magnetic body moves from the state I shown by the solid line to the state II shown by the imaginary line, the intensity of the magnetic field produced by a magnet 8 becomes weak on the side of a magneto-resistance element 6b where the peripheral surface part 3a moves away. Therefore, the potential between terminals B and C varies.
