    摘要： A thread groove type vacuum pump in which the gap between a rotor and a stator is not subjected to any influence of the rotor temperature and thus the pumping performance does not deteriorate during plasma combustion in a nuclear fusion reactor. The thread groove pumping portion is formed as a circular cone so that the expansion and contraction of the rotor occurs along the generatrix of the circular cone. The pump exhibits supreme pumping performance throughout the whole running mode of the vacuum pumping system of the nuclear fusion reactor because the gap between the rotor and the stator is kept constant despite changes of thermal expansion due to the temperature change of the rotor caused by the different gas loads.

    摘要： An armature stator comprises an iron core and a coil directly mounted on the iron core. The coil is composed of wound electric wire which has a coating comprising an inorganic material, such as ceramic. A bonding material of the inorganic material is formed over the coil and iron core for filling any gaps and adhering the coil and iron core together into a unitary structure. To improve the reliability of the coil, after the electric wire is wound to form the coil, a filling material comprised of the inorganic material is formed over the coil by vacuum impregnation, and then sintered so as to repair defects in the coating disposed on the electric wire. After the bonding material is formed over the coil, which is directly mounted on the iron core, it is cured under high temperature. The armature stator thus constructed can be used with high reliability in high temperature and high vacuum applications.

    摘要： The present invention relates to improvement of a quadrupole electrode for use in a mass spectrometer or the like, in which two pairs of electrode rods 1, 2, 3 and 4 formed in such a manner that the section of the opposed face of each rod is hyperbolic or circular, and each electrode rod is made of a ceramic and the surface of the electrode is coated with a coating layer 5 of a conductive metal. Further, the present invention relates to a production process, characterized by incorporating such four electrodes at predetermined intervals. Since the electrodes are mainly made of a ceramic which is easily formable with a high dimensional accuracy, the adjustment of the positional relationship between the electrodes during assembling can be made without much effort, which enables a quadrupole electrode having a high performance to be provided with a good reproducibility at a low cost.

    摘要： A vacuum vessel is provided in which the majority of a vessel wall including an annular wall portion (1) and a plate-wall portion (2) is formed of ceramic material such as silicon nitride, for example. To bond the plural wall members together, bonding faces having a surface flatness of not more than 1 .mu.m are prepared thereon, and then a ceramic powder bonding substance with an average particle diameter of not more than 1 .mu.m is interposed between adjacent bonding faces and subjected to heating. Because the generation of gas, such as hydrogen, from the wall of the ceramic vessel is reduced, extremely high vacuum can be generated and maintained in the interior of the vacuum vessel. Also, because the wall of the vacuum vessel has a high permeability with respect to a magnetic field and an electric field, the vacuum vessel can be used as a vessel in a particle accelerator that allows the high precision control of charged particles therein by means of an electromagnetic field.
