Abstract: An electron gun according to one aspect of the present invention includes an emission source configured to emit an electron beam, an aperture array substrate, where a plurality of passage holes are formed, configured to form multiple beams by letting portions of the electron beam individually pass through the plurality of passage holes, and a first electrode, where a first opening through which the electron beam can pass is formed, configured to include an opposing plane which is located at a side of the emission source with respect to the aperture array substrate and facing a surface of the aperture array substrate and whose outer diameter is smaller than an outer diameter of the aperture array substrate, the first electrode configured to be applied with a first control potential.

Abstract: A base sequence detection apparatus is provided with a channel formed on a base sequence detection chip. Working electrodes are formed along the channel and include a probe immobilized thereon, counter electrodes are formed on the inner surface of the channel and, reference electrodes are formed on the inner surface of the channel. An introduction port introduces solution or air from the upstream side of the channel, a delivery port delivers the solution or air in the channel, and the sample is injected into the channel through a sample injection port.

Abstract: A method of manufacturing an electrostatic deflecting electrode unit for use in charged beam lithography apparatus comprises a first step of preparing a hollow cylindrical member made of metal, a second step of forming grooves of a predetermined width in a cylindrical member in the direction of radius thereof and along lines that equally divides the periphery of the cylindrical member into eight sections, a third step of attaching a ring-like member made of an insulating material to each of end surfaces of the cylindrical member which are opposed to each other in the direction of axis of the cylindrical member in such a way that bottom portions of the grooves are exposed, and a fourth step of dividing the cylindrical member into eight electrodes by extending the bottom portions of the grooves in the direction of radius of the cylindrical member to reach the hole of the cylindrical member with the ring-like members attached.

Abstract: An apparatus for forming thin organic films includes a plurality of water tanks each containing water. Monomolecular films of different amphiphatic organic molecules are developed on the surface of the liquid in water tanks, respectively. A work is dipped into and drawn up from a desired water tank, by a driving device, in a direction substantially perpendicular to the liquid surface, so that the monomolecular film in the water tank is adhered on a work surface. The work is transported by a transporting device to a position above another water tank, through an area lying above the water tanks. Then, the work is dipped into and drawn up from the other water tank, by the driving device, in a direction substantially perpendicular to the monomolecular film, so that another monomolecular film is adhered on the monomolecular film already formed on the work surface.

Abstract: An organic film forming apparatus includes a trough storing water therein and a work drive device for moving a work with respect to the trough. The surface of the water is partitioned by a rod into a first developing region on which a monomolecular film is developed and a second developing region on which no monomolecular film is developed. The work is moved by the device through the developed monomolecular film so as to adhere the film on the surface of the work. The device has a holding mechanism which has a holding portion engaged with the work, and which holds the work so that when the work passes through the developed monomolecular film, the holding portion is away from the film or passes through the film after almost the entire work passes through the film.

Abstract: An apparatus for forming thin organic films includes a plurality of water tanks each containing water. Monomolecular films of different amphiphatic organic molecules are developed on the surfaces of the liquid in water tanks, respectively. A work is dipped into and raised out of a desired water tank, by a driving device, in a direction substantially perpendicular to the liquid surface, so that the monomolecular film in the water tank is adhered on a work surface. The work is transported by a transporting device to a position above another water tank, through an area lying above the water tanks. Then, the work is dipped into and raised out of the other water tank, by the driving device, in a direction substantially perpendicular to the monomolecular film, so that another monomolecular film is adhered on the monomolecular film already formed on the work surface.
