Abstract: PROBLEM TO BE SOLVED: To provide a manufacturing method for an electron source capable of uniformly activating the whole electron emission element. SOLUTION: An activation process is so formed that set values of a partial pressure of activation gas are changed in multiple stage and a compensation voltage is not applied prevented for a prescribed period of time after changing the set value. Alternatively, the activation processes are repeatedly performed for multiple times while changing a single line wiring or column wiring and the compensation voltage is prevented from being impressed for the prescribed period of time after changing the line wiring or the column wiring.

Abstract: PROBLEM TO BE SOLVED: To lessen the dispersion of the film thickness by imparting aqueous solution droplets containing an organic metal compound having a surface active agent as ligands between electrodes, and heating burning a substrate to form a conductive film at a droplets-imparted portion to be an electron emission portion. SOLUTION: After an insulating substrate 1 is washed and element electrode material is deposited by a vacuum deposition method, or the like, element electrodes 2, 3 are formed. Organic metal solution is applied to the electrodes 2, 3-provided substrate 1 so as to form an organic metal film, and the same is heating burning treated, is conducted patterning by etching or the like so as to form a conductive thin film 4. A particulate film composed of particulates is used for the thin film 4 in order to obtain excellent electron emission characteristics, and the film thickness thereof is set to be in a range of 10Å to 500Å. When a current is carried between the electrodes 2, 3, a place, where structure change such as braking, deformation, alteration, or the like is locally brought about in the conductive thin film 4, is formed, and the place constitutes an electron emission portion 5. Further the same acts as a surface active agent so as to be effective in wetting control of the substrate, the electrodes, and the like.

Abstract: PURPOSE:To detect the weak infrared absorption spectrum of a low- concentration substance to be analyzed (solute) without diminishing the separating ability of a column by fitting a multiple-reflection prism for infrared rays to the outside of an infrared spectroscopic cell. CONSTITUTION:The window of an infrared spectroscopic cell is formed by hollowing out part of the cell and fitting a multiple-reflection prism for infrared rays 2 in the hollowed out part. Any material, for example, zinc selenide or germanium can be used for the prism 2 when the material is insoluble in the moving phase of liquid chromatograph and transmits infrared rays. However, it is preferable to use a mixed crystal of thallium bromide and thallium iodide, potassium bromide, etc., when a nonpolar organic solvent is used as the moving phase. It is also preferable to attach a secular-finished metallic plate 1 to the prism 2 forming the window of the cell.

Abstract: PURPOSE:To recover a sample dropped from a measuring stage without opening a high-vacuum measuring chamber to the atmospheric air by providing a sample recovering plate for capturing the dropped sample below the sample stage rotatably and vertically movably. CONSTITUTION:A sample recovering plate 16 made of a circular 10-mesh stainless steel net is fixed to a stage rotary shaft 14 below a sample stage 10 in parallel with the stage 10 face. A sample 26 mounted on the sample tray is fed to the stage 10 from the outside by a sample conveying tool 22 via a reserve exhaust chamber 8 and mounted on a mount hole, and it is conveyed near an X-ray source 4 in sequence by the rotation of the stage 10 and analyzed. If the sample 26 is dropped on the recovering plate 16 when it is mounted on the stage 10, the rotary shaft 14 is rotated to move the sample below the conveying tool 22, then the rotary shaft 14 is lifted, and the conveying tool 22 is operated to pick up and recover the sample 26. The rotary shaft 14 is lowered and returned to the original state, and the recovered sample 26 is again mounted on the stage 10.

Abstract: PROBLEM TO BE SOLVED: To miniaturize an electron source manufacturing equipment and to simplify its operability, by providing a container to cover a part of the region where a conductive body is formed on a base surface, a means of introducing a gas to the container connected to the outlet of the gas, and a means of evacuating the container, and a means of applying a voltage to the conductor. SOLUTION: A supporting body 11 holds and fixes an electron base 10, and a vacuum container 12 of glass or stainless steel covers the region where a conductor is formed except for a wiring part to take out the electron source base 10. An organic gas material 21 and a carrier gas 22 are mixed at a fixed rate, and are introduced into the vacuum container 12 from an inlet 15. Mixed gas introduced is exhausted at a fixed exhausting speed by a vacuum pump 26 through an outlet 16, and a pressure in the vacuum container 12 is kept at a constant level. Since the vacuum container 12 is required to cover only the conductor on the electron source base 10, the equipment can be miniaturized, and since the wiring part of the electron source base 10 is outside the vacuum container 12, it can be easily and electrically connected to a driving driver 32.
