摘要： PURPOSE:To make it possible to pick up stably electric field emission electron beams with low aberration and high luminance by getting magnetic flux trapped in positive electrodes made of a superconductor to make it act as a lens. CONSTITUTION:The first positive electrode 41 or the second positive electrode 45 is or both of them are made of a superconductive material with an exciting equipment 40 provided for trapping flux in this superconductive material. Further a temperature adjusting mechanism is arranged to change individually into normal state or superconductive state the superconductive positive electrode 41 optionally selected from plural superconducive electrodes 41, 45 being close to each other. The first and second positive electrodes 41, 45 forming an electrostatic lens also act as a magnetic field type lens so that a permanent current does not produce Joule heat and degree of vacuum in an electron gun is not deteriorated. Accordingly, the electrodes can be forced to act as a lens with very low aberration and electron beams can be picked up with high luminance and big current.

摘要： PURPOSE:To control scattered material distribution in a branch passage and to produce a large quantity of transistors having the same characteristics for a magnetic field or an electric fieled by so disposing substance or superconductor having higher permeability than that of a substance for forming a plurality of matter wave propagating passage as to shield the passage from a magnetic flux. CONSTITUTION:A matter wave is incident from an incident passage 21, two matter waves capable of interfering at a branch point 22 are generated, propagated at branch passages 23, 23, superposed, interfered at a confluent point 5, and emitted from an emitting passage 26. In this case, a magnetic field is applied perpendicularly to this paper, and the intensity of the wave emitted from the passage 26 is varied. In this instance, in order to prevent the applied magnetic field from passing through the passages 23, 24 themselves, a magnetic shielding layer 18 made of a superconductor is provided to substantially enclose the passages 23, 24. The lines 20 of magnetic force of the applied magnetic field are passed by avoiding the passages 23, 24 by means of Meissener effect of the superconductor. Thus, it can substantially completely prevent the magnetic flux from passing through the two passages.
