摘要:
An apparatus and method for producing positive and negative ions and/or electrons in a gas of any atmosphere without producing dust, a method and structure for neutralizing a charged body in a short period of time and for completely preventing static electricity from being generated, and various apparatuses and structures, such as a conveyor, wet bench, and clean room, which use the neutralizing method and structure. The gaseous ion producing apparatus produces positive and negative ions and/or electrons in a gas by irradiating, with electromagnetic waves in a soft X-ray region, the gas under a high pressure, atmospheric pressure, or reduced pressure. In the neutralizing structure an X-ray unit is arranged at an appropriate place to apply the electromagnetic waves in a soft X-ray region to the atmospheric gas surrounding a charged body.

A gas discharge tube (1) having a layer of coating (21) comprising a glass material or a ceramic material on either or both of an inner surface (22A) and an outer surface (22B) of a side tube body (22), so that the side tube body (22) can be formed of various materials irrespective of the nature of a gas sealed in the interior of the gas discharge tube, this enabling the diversification of the worked shape of the gas discharge tube and the miniaturization of the same tube to be compatible with each other, and the mass production thereof to be carried out freely.
摘要:
A gas discharge tube (1), wherein a side tube member (14) is formed of glass with a metal employed for joint portions of a stem (4) and side tube member (14), so as to prolong the lifetime of the discharge tube while lowering a discharge tube assembling temperature, a first metal circumferential portion (15) provided on the stem (4) and a second metal circumferential portion (16) provided on the side tube member (14) being utilized as the joint portions, this enabling the discharge tube (1) to be miniaturized.
摘要:
A gas discharge tube (1), wherein high-temperature heat generated in an anode (6) during the use of the gas discharge pipe is transmitted to a stem (4) via an anode support plate (5) owing to a structure in which the anode support plate (5) is in contact with the stem (4), the high-temperature heat being then discharged from the stem (4) to the outside to improve an efficiency in cooling the anode (6), the anode (6) being stable on the stem (4) since a structure in which the anode (6) is seated on the stem (4) via the anode support plate (5) is employed instead of a floating structure involving a stem pin (10), whereby the earthquake resistance of the anode is improved, this also contributing to an easier and simpler work for assembling the gas discharge tube (1) since the anode (6) can be incorporated in a sealed case (2) by merely placing the anode support plate (5) on the stem (4).
摘要:
A flange portion 4A is integrally formed with a stem 4 which forms a sealing envelope for a gas discharge tube. Accordingly, operation for building and fixing the flange portion 4A is not necessary, so that lamp assembly operation is simplified, and mass production is facilitated. In addition, when a gas discharge tube 1 is to be fixed to an external stem setting portion 17, lamp setting is enabled at higher precision by utilizing positioning holes 22 formed in the flange portion 4A in advance.
摘要:
In a gas discharge tube 1 in accordance with the present invention, one or both of the inner wall face 22A and outer wall face 22B of a side tube body 22 are provided with a coating 21 made of a glass material or ceramics. As a result, the side tube body 22 can be made of various materials regardless of properties of the gas filling the inside, whereby the gas discharge tube 1 can have a wider range of processed forms and smaller dimensions at the same time, and its mass production can freely be carried out.
摘要:
A gas discharge tube, wherein a stem (4) forming a sealed case for the gas discharge tube is provided with a flange portion (4A) integral therewith, this enabling a lamp assembling operation to be simplified without requiring an operation for combining and fixing the flange portion (4A) with and to the gas discharge tube, the gas discharge tube to be easily mass-produced, and, moreover, a positioning hole (22) provided in advance in the flange (4A) to be utilized to fix the gas discharge tube (1) to an external stem setting portion (17), whereby a more accurate lamp setting operation can be carried out.
摘要:
In the gas discharge tube of the present invention, for elongating the life of the discharge tube 1 itself while lowering the assembling temperature, a side tube 14 itself is formed from glass, and a metal is employed in a joint between a stem 4 and the side tube 14. Namely, a metal-made first peripheral portion 15 provided in the stem 4 and a metal-made second peripheral portion 16 provided in the side tube 14 are utilized in the joint. As a result, the discharge tube 1 itself can be made smaller.
摘要:
While high heat is generated in the anode section 6 in the gas discharge tube 1 in accordance with the present invention during its use, the heat is transmitted to the stem 4 by way of the anode support plate 5 due to a configuration in which the anode support plate 5 abuts against the stem 4, and is released outside from the stem 4, whereby the cooling efficiency of the anode section 6 is improved. Since the anode section 6 employs not a floating structure including stem pins 10 interposed therein but a configuration in which it is seated on the stem 4 by way of the anode support plate 5, the anode section 6 is stabilized on the stem 4, whereby the resistance to vibration improves. Also, for assembling the anode section 6 into a sealed envelope 2, it will be sufficient if the anode support plate 5 is mounted on the stem 4, which contributes to improving the easiness in assembling the gas discharge tube 1.
